1.3.1 UTILITY THEORY
The analysis of consumer behaviour in economics is concerned with:
How consumers choose what quantity of any good to purchase
Why consumers’ demand for a good generally fall down as its price goes up
How consumers change their spending pattern if their income rises or falls
One theoretical way of explaining this is the concept of utility.
Utility is the satisfaction that a consumer obtains from the consumption of
commodities
For any commodity, the marginal utility that a consumer gets from the
consumption of an extra unit of the commodity will tell, as the consumption
increases. This is the law of diminishing marginal utility
Consumer equilibrium is reached, at a given income level by spending on
goods so as to maximize total utility from all the goods purchased.
Suppose that a household buys two commodities, X and Y.
Let the marginal utility of a unit of X be MUx and the marginal utility of a unit
of Y be MUY.
Let the price per unit of X (in pence) be PX and the price per unit of Y be PY.
The household will attain a utility-maximising equilibrium where the marginal
utility from the last Rupee spent is the same for X and Y.
i.e. where: Y

1.3.2. Indifference Curve Analysis
An indifference curve is a line on a graph that shows the combinations of:
Two products, X and Y or
One product X and ‘all other goods’ which, if purchased, will give consumers
the same total satisfaction or utility.
3
With a given income or budget for spending on goods, consumers will
maximize their total satisfaction or utility by purchasing quantities of X and Y, or
quantities of X and ‘all other goods’ which lie on an indifference curve as far from
the origin as possible. This will be an indifference curve that touches the budget
line at a tangent. (See diagram below).

maximizes consumer utility with a given budge rot

As consumers’ income increases the budget line will move further from the
origin, and an indifference curve that touches the new budget line at a tangent will
also be further from the origin, providing greater maximum total satisfaction for
consumers.
Price effect
A price change given the same total consumer money income, will alter
consumers’ real income.
A price will mean that consumers can afford to buy less
A price reduction will make consumers able to buy more The slope of the
budget line will change.

In the diagram above, an increase in the price of X will alter the consumer’s
budget line from BB to BB1. They can afford less of X with their income.
The new utility-maximising combination of X and Y changes from point J on
indifference curve I2 to point H on indifference curve I1. The higher price of X
4
means that consumers will now buy less. There are two reasons for the shift from J
to H.
Substitution effect
Product Y is now cheaper than before, compared with the price of X.
consumers will therefore buy more of Y. This is illustrated in the diagram by
drawing a line AA parallel to the new budget line BB1, that touches the ‘old’
indifference curve I2 at a tangent.
Given the change in relative prices, if consumers had enough income, they
would now prefer to combine purchase of X and Y at point K rather than at point J.
This is the so-called substitution effect of the price change.
Income effect
But consumers don’t have more income to afford to buy the combination of X
and Y at point J. The rise in the price of X means that they will buy the
combination at point H. The fall in their real income means that they will demand H
rather than K.
This difference is the so-called income effect of the price change. This analysis
can be used to show how consumer demand for most products will fall as the price
of the product goes up.
Exceptions, where demand rises if price rises, are:
‘Giffen goods’
Goods bought for ostentation
1.3.3 CONSUMER SURPLUS
The negative slope of the demand curve (or inverse relationship between price
and quantity demanded) is illustrated in Figure Linear and non-linear demand
relationships gives rise to a concept that has often been influenced in guiding
economic policy known as consumer surplus. This is defined as follows:
A consumer’s surplus is the excess of the price which a person would be
willing to pay rather than go without the good, over that which he actually does
pay.
In other words, the gap between the total utility of a good and its total market
value is called consumer surplus. The surplus arise because we “receive more than
we pay for”: such bonus is rooted in the law of diminishing marginal utility.
It is easy to observe how this consumer surplus arise. We pay the same price
for each egg or glass of water. Thus we pay for each unit what the last unit is
worth. But by our fundamental law of diminishing marginal utility, the earlier
units are worth more to us than the last. Thus, we enjoy a surplus on each of
these earlier units. When trade stops benefiting us the stops giving further
surplus, we stop buying.
This is also sometimes referred to as consumer’s rent. The magnitude of
consumer surplus can be approximated by the area under the demand curve,
5
which represents the additional aggregate payment consumers would pay in excess
of the amounts actually paid for a good at the going price. For example, area p’p’’B
if the product was sold at price p” in Figure Linear and non -linear demand
relationships.

One way of appreciating the meaning of this concept is to imagine that goods
are sold on an open auction basis so that each potential consumer is able to bid the
price that he or she is willing to pay – individual. If the good is being sold by a
discriminating monopolist, the objective would be to ensure that no consumer
surplus remains. In other words, everyone will have paid a price that just equals
the valuation they have each placed on the good. Consider the value (i.e. price) you
would place on a drink of water, if you had been in the desert for a week relative to
that which someone else in a more ‘comfortable’ situation would place on it!
The concept of consumer surplus is useful in making many decisions about
public goods—it has been employed in decisions about airports, roads, dams,
subways, and parks.

In order to maximize profits, a firm endeavours to increase its revenue and
lower its cost. To this end, managers try to produce optimum levels of output, use
the least-combination factors of production, increase factor productivities, and
improve organizational efficiency. If there is no cost, the firm will always benefit
from an expansion of its production. If cost is prohibitive, the firm may not find it
profitable to produce at all. In other situations, the level of production will be
governed by cost of production, among other factors.
Cost of production provides the floor to pricing. It provides a basis for
managerial decisions with respect to the price the firm must quote to its prospective
customers, in deciding whether to accept a particular order or not, whether to
8
abandon an old or establish a new product line, whether or not to increase the
volume of specific outputs, to use idle capacity or rent facilities to outsiders, and
whether to make a particular product or buy it. There are no straight and simple
rules for such decisions and it is necessary to study production and cost analysis
thoroughly to arrive at these decisions. The costs which firms incur are payments
to various factors of production and hence they indicate incomes of these factors
also. An understanding of cost thus helps to understand the distribution of factor
incomes as well.
Production and cost analysis is concerned with the supply side of the market.
Production analysis is done in physical terms while cost analysis is discussed in
monetary terms. The former relates physical output to physical units of factors of
production, and studies the least cost combination of factor inputs, factor
productivities, and return to scale. The latter deals with various types of costs and
their role in decision making, determinants of costs both in the short and long-run,
and the determination of cost functions and their uses in decision making. This
chapter, discusses the production function and related concepts first, and then
goes on to cost analysis.
2.3.2 Production Function
A production function expresses the technological or engineering relationship
between the output of a commodity and its inputs. Traditional economic theory
speaks of four factors of production, viz., land, labour, capital and organization or
management. Technology also contributes to output growth and it is now regarded
as an additional determinant of output. Thus, the output of an industry is a
positive function of the quantities of land, labour and capital, the quality of
management, and the level of technology that is employed in its production.
Symbolically, it can be denoted as follows:
x = f(Ld, L, K, M, T)
f1, f2, f3, f4, f5 > 0
where x = output of commodity X
Ld = land employed in the production of X
L = labour employed in the production of X
K = capital employed in the production of X
M = management employed in the production of X
T = technology employed in the production of X
f = unspecified function
f1 = partial derivative of f with respect to the i th independent variable.
Function above describes a general production function. In a specific situation,
one or the other of these various factor inputs may not be important and the
relative importance of a factor of production varies from one type of product to
9
another. Land is perhaps the most important input factor in the case of an
agricultural product while it is of minor importance in the case of a manufacturing
product. Production of wheat, for example, can be increased through the use of
more and better quality of fertilizers, more and timely irrigation, etc., but beyond a
point increase in land becomes necessary for a further increase in its production. In
contrast to this, the production of steel, for example, can be increased significantly
without any increase in the land occupied by the steel industry. Besides, more land
may not even be available near a steel factory and occupying land at any other
place may not be convenient and profitable. Furthermore, the investment in land is
a significant part of the total cost of wheat production while it is an insignificant
component of the total cost of steel. Similarly, the role of management and
technology may be more crucial in the case of an industrial product than in the
case of an agricultural product. For these reasons, researchers often modify
function above to suit their specific objectives.
For a good exposition of production decision problems, it is convenient to work
with two input factors for an output. If labour and capital are the only two inputs,
the production function (3-1) reduces to
x = f(L,K)
Function has three variables: output of commodity X (x), units of l Labour (L)
and units of capital (K). For a given value of x, there will be alternative
combinations of L and K. These combinations of L and K will vary with variations in
x. generally speaking, both labour and capital are necessary for the production of a
commodity and they are substitutes to each other. Thus for any given level of
output, an entrepreneur will need to hire both labour and capital but he would
have an option to employ any one combination of these factors out of several
possible combinations. The alternative combinations of factors for a given output
level will be such that if the use of one factor input is increased that of another will
decrease and vice versa. To illustrate this, consider the hypothetical example of an
entrepreneur engaged in making shoes. In order to make shoes, he needs at least
one cobbler, and some capital, which consists of leather, thread, sewing tools,
machines, etc. For making a given number of shoes, he would have alternative
combinations of labour (cobbler) and capital, for labour and capital are substitutes
to a certain extent. For example, a cobbler having the minimum tools would hardly
be able to complete one pair of shoes in a day while another cobbler of the same
efficiency having a sewing machine and other useful tools could perhaps make two
pairs of shoes in a single day. The alternative combinations of labour and capital for
making different numbers of shoes per day are illustrated in Table.

6 3 7 4 8 5 9 7 10 10
An isoquant by definition is the locus of all those combinations of labour and
capital which yield the same output. In our example, the entrepreneur could
employ 1 cobbler and 20 units of capital, 2 cobblers and 12 units of capital, 3
cobblers and 8 units of capital,…., or 6 cobblers and 3 units of capital to
manufacture 2 pairs of shoes. If he aims at producing 5 pairs of shoes, the
alternative input combinations open to him are 2 cobblers and 20 units of capital, 3
cobblers and 14 units of capital, and so on. If we plot these alternative input
combinations for a given output and assume a continuous variation in the possible
combinations of labour and capital, we can draw a curve called isoquant for the
given units of output. The isoquants for various output levels of Table are shown in
Figure Isoquants.
The family of isoquants or iso-product curves makes up all the possible
combinations of labour and capital that can be employed to produce different
outputs of a commodity. Thus, they are geometric representation of a production
function. The isoquant in Figure represent the production function in our
hypothetical shoe industry.

Figure Isoquants
The shape of these isoquants is such that
a) they are falling,
b) the higher the isoquant is, the higher the output it represents,
c) they do not intersect each other, and
11
d) they are convex from below.
An isoquant is falling, for it can neither be rising nor constant. A rising
isoquant implies that output does not increase with increase in labour and capital,
which is obviously not true. A horizontal or vertical isoquant means that output
does not respond to variations in one of the input factors, others remaining
constant. This is also not true because usually output increases with an increase in
any one factor of production, others remaining the same. For similar reasons, a
higher isoquant represents a higher level of output.
An isoquant never intersects another isoquant, for if they did it would mean
that with the same units of labour and capital, two different levels of output can be
produced, which is absurd. The isoquants are convex from below because
substitution of labour for capital becomes more and more difficult as more of labour
is substituted for capital. In our hypothetical example, the isoquant x = 2, for
example, is convex from below because when labour is increased from 1 unit to 2
units, capital use is reduced from 20 units to 12 units, a fall of 8 units, a fall of 4
units, and so on. The rate of substitution, which was 1 unit of labour = 8 units of
capital, changed to 1 unit of labour = 4 units of capital. This is because of
increasing difficulties in substitution. If labour and capital were perfect substitutes,
isoquants would have been falling straight lines as in Figure Isoquants when
Factors are Perfect Substitutes.]Figure Isoquants when Factors are Perfect
Substitutes
On the other hand, if one factor of production could not be substituted for
another at all, isoquants would be rectangular as in Figure Isoquants when Factors
are Perfect Non-substitutes.

In addition to the above properties of isoquants, it may be noted that they do not touch either the
labour or the capital-axis. This is because, as stated above, both labour and capital are necessary for
the production of any commodity.
2.3.3 Least-cost Combination of Inputs
The production function indicates the alternative combination of various
factors of production which can produce a given output. Of these, an entrepreneur
would like to choose that combination of input factors, which costs him the least.
To explain how he can determine the least cost combination for a given output, we
need the prices of the factors of production. Let the price of labour (P L) be Rs.9 per
unit and the price of capital (PK) Rs.6 per unit. Assume that any amount of labour
and capital can be bought at these respective fixed prices. Let our entrepreneur
make nine pairs of shoes. The alternative combinations of labour and capital open
to him are as given in the columns headed by x = 9 in Table Input-Output
Relationships and isoquant x = 9 Figure Isoquants. Let us now determine his least
cost combination.
There are two ways to determine the least cost combination of inputs for a
given output. One way is to find the cost of each input combination and choose the
one which has the least cost. The cost of an input combination is found by
multiplying the price of each input by its quantity and then summing it over all
inputs. In our example, there are six alternative combinations of labour and capital
to produce nine pairs of shoes. The cost of each of these combinations will be as
follows:
13
Combination 5 represents the least cost for producing 9 pair of shoes. The
least total cost of producing various other quantities can be determined in a similar
way.
Combination Inputs Units
Costs (Rs.) L K
1 3 20 3 × 9 + 20 × 6 = 147
2 4 13 4 × 9 + 13 × 6 = 114
3 5 10 5 × 9 + 10 × 6 = 105
4 6 8 6 × 9 + 8 × 6 = 102
5 7 6 7 × 9 + 6 × 6 = 99
6 8 5 8 × 9 + 5 × 6 = 102
A more general way to determine the least cost combination is geometrical in
nature. We first draw iso-cost lines as follows. With a given sum of money C and
only two factors of production, labour and capital, the quantities of labour and
capital one can purchase are given by
C = LPL +KPK
If a shoe-maker has Rs.99 at PL = Rs.9, PK = Rs.6, he can buy 11 units of
labour with no capital, 16.5 units of capital with no labour, 7 units of labour and 6
units of capital, and so on. The various combinations of labour and capital that he
could buy with Rs.99 are represented by the line C = 99 in Figure Iso-cost Lines.

Figure Iso-cost Lines
Line C = 99 is an iso-cost line. It is the locus of all those combinations of
labour and capital which could be bought for Rs.99. similar isoquant lines can be
drawn for different sums of money. Figure Iso-cost Lines gives a few iso-cost lines.
It may be noted that all these iso-cost lines are parallel, for factor prices are the
same in all cases.
In order to determine the least cost input combination or the maximum output
for a given cost, we superimpose the isoquant map on the iso-cost map as shown in
Figure Least-Cost Input Combination.
It is seen that the maximum output that can be obtained with an outlay of
Rs.99 is 9 pairs of shoes, where the iso-cost line C = 99 is tangent to the isoquant x
= 9 at point C. Rs.99 is the least cost of producing 9 pairs of shoes, and the least
combination of inputs for this output is 7 units of labour and 6 units of capital. Any
other input combination on isoquant x = 9 will have a cost higher than Rs.99. For
example, input combinations at points C1 and C2 would cost Rs.105 and Rs.102,
respectively. Similarly, the least-cost input combinations for output levels 2, 5, 12
and 14 are given by points A, B, D and E, respectively in Figure Least-Cost Input
Combination. Thus, the line ABCDE represents the least cost combinations of
inputs for different levels of output. It denotes the expansion path and is called the
scale line.
2.3.4 The Analysis of Production Costs
In this part we examine the internal operations of business by analyzing the
nature of costs of production and the impact costs have on business decision -
making. Some of the questions which managers face are as follows:
Whether to increase or reduce production at the margin as bottlenecks are
reached?
Whether to increase production using more labour?
Whether or not to increase the overall scale of production by expanding to a
new plant size?
Just as consumers, given limited incomes, make decisions about what goods
to buy and in what quantity, so managers must make decisions about how much to
produce (the size of output) and how to produce; in terms of the combination of
inputs (i.e., labour, raw materials, capital equipment and so on), again with limited
resources. These decisions will depend heavily on the relevant costs of production.
In this lesson, the following concepts are covered:
The production function.
Variable costs versus fixed costs.
Production decisions in the short run and long run.
Diminishing returns in production.
Maximizing profit and the production decision.
Economies and diseconomies of scale.
15
In managerial decision-making, an understanding of the firm’s costs of
production and how they change as output is increased or reduced is essential. Of
course, behind increases and reductions in costs of production lie considerable
changes in the internal workings of the firm. Hence the good manager constantly
keeps in mind the impact of output decisions on the so-called ‘stakeholders’ in the
firm: employees, shareholders, suppliers, customers, etc. Other management
subjects such as corporate strategy and organizational behaviour deal with the
internal decision-making process within firms and the effect this has an outcomes.
In contrast, economists are more concerned with the nature of the relationship
between the firm and its market – the competitive environment – and more
specifically the relationship between output, price and costs of production, which in
turn affects the employment of factors of production. We therefore start this lesson
by considering the relationship between inputs and outputs as described by the
production function.
The production function and costs of production
Firms are essentially involved in adding value by converting inputs into
outputs. Firms employ labour, purchase materials and components, and invest in
land, buildings, plant and equipment with a view to maximizing the amount of
output that can be derived from these inputs. These inputs can be combined in
different ways (e.g. labour intensive versus capital intensive production) and we
might expect the decision as to the precise combination used to be related directly
to the costs of different forms of production. In this discussion we adopt the
position that managers are interested in minimizing the cost of producing any given
output, though we acknowledge that in practice there may be constraints (e.g.
union manning agreements) which prevent the kind of smooth adjustment process
as set out in the following discussion. Throughout most of the discussion in this
lesson it is assumed that the firm is not wasting resources, that is to say, it is
assumed that it is minimizing its cost of production at any given output.
The production function is a mathematical expression which relates the
quantity of all inputs to the quantity of outputs assuming that managers employ all
inputs efficiently.
In general terms the production function for any firm may be expressed as
follows:
This expression is a shorthand notation to show that the quantity (Q) of output
produced is determined by (or a function (F) of) a range of inputs (I1 to In). The
inputs or factors of production I1 to In are classified by economists under the
general headings of labour, land and capital though the production function can
equally relate output to different types of labour, capital, etc.
It may not always be obvious to managers what the precise technical
relationship is between their firms’ inputs and outputs. However, it must be the
Q = F(I1, I2, I3…….In)
16
case that there is a relationship and economists have derived a number of general
mathematical forms to describe typical relationships.
Variable costs Versus Fixed costs
In the production process some costs are fixed in the sense that they do not
vary as output changes. For example, the lease rent on an office and the capital
cost of a computer (including interest charges) are examples of costs which once
incurred usually remain the same as output rises – the fixed factors of production.
In contrast, those costs which do not change with output are known as the variable
costs. If more goods or services are produced, more inputs are employed and
variable costs increase. The kind of inputs involved are raw materials, components,
energy, telephone usage and, often, staffing levels – the variable factors of
production.
It is useful to analyze the way in which fixed costs and variable costs behave
as the level of production changes. Such analysis allows us to identify whether or
not resources are being used most efficiently. If total fixed costs and total variable
costs are averaged over the various levels of output, we can derive values for
average fixed costs (AFC) and average variable costs (AVC). Combining the AFC and
the AVC gives average total costs (ATC). These costs are illustrated in Figure-the
costs of production. The key points to note about the nature of these costs are the
following:
Average fixed costs: As the fixed costs are distributed across more and more
output, the average fixed costs decline continuously until at very large output levels
they are negligible.
Average variable costs: Average variable costs may fall initially but after a
certain level of output they begin to rise. This occurs because of what economists
term the law of diminishing returns, mentioned in lesson and discussed more fully
below. It is, of course, possible for average variable costs to rise continuously as
output expands (as in Figure - the costs of production), while in some businesses
there may be a large output range over which they are constant.
Average total costs: Average total costs, being the combination of AFC and
AVC, tend to decline initially and then rise after a certain level of output is reached.
Average total cost is often referred to by accountants as the unit cost. It is also
often referred to as average cost.
The extent to which a firm can alter its factors of production is dependent
upon the time period concerned. In general, the longer the time period the more
scope a firm has to vary its inputs. The importance of the time dimension in
production decisions gives rise to the concepts of the short run and long run.

2.3.5 Production decisions in the short run and long run
The short run is the time period during which the amount of at least one input
is fixed in supply (e.g. the amount of capital equipment installed or in some
organizations the number of personnel employed) but the other inputs can be
altered. In essence, the short run is the operating period of the firm where the
management has already made a technical decision about the production
process: for example, in a bank so many cashiers are employed using a given
number of automatic teller machines in a particular branch. To expand the
volume (output) of service it may be possible to employ more staff relatively
quickly, but to expand the floor area of the branch and to incorporate more
capital equipment will usually take much more time and planning.
The long run, therefore, represents a sufficient length of time for management
to be able to vary all inputs into the production process. This is also known as
the planning horizon of the firm in contrast to the current operating period. For
example, in order to meet a growing demand from customers the bank’s
management may decide over the next five years to purchase a much larger
building capable of housing many more cash machines and employing a much
larger number of staff. The bank will therefore over this period have moved
from one scale of operation to another which in turn will give rise to different
set of cost relationships.
18
It is important to appreciate that the terms short run and long run should not
be interpreted too rigidly. They are defined according to the extent to which the firm
is able to alter its inputs and this will vary from business to business. For example,
in large-scale manufacturing plants with high set-up costs, it is obviously difficult
to expand production quickly beyond the capacity of the plant, though it may be
possible to achieve this over a longer time period through more investment. The
length of time in the case of nuclear power generation is many years, while, by
contrast, in service-orientated businesses the planning period may be relatively
short. It may be quicker to buy and install a new microcomputer than to train new
staff.
2.3.6 Diminishing Returns in Production
Assuming that the firm is using its existing resources efficiently, the extent to
which output can be increased is dependent upon the extent to which inputs can be
varied. In the short run, as more and more variable inputs are applied to the fixed
factors of production, we tend to find that at first average (unit) costs fall but eventually
they begin to rise because diminishing returns set in. Economists refer to this trend
as the law of diminishing returns. It is easy to think of cases where this will occur in
manufacturing. For example, if the Maruthi motor company faces a sudden surge in
demand for its Alto range of cars and attempts to meet this extra demand by simply
employing more workers on a given assembly line, a point will be reached when
manning exceed the optimal level and unit costs rise. Therefore, if the company
believes that the increase in demand is permanent, it would be better to begin planning
an increase in capacity. Diminishing returns also apply in the service sector. For
instance, imagine a retail store attempting to serve more and more customers by
simply employing additional sales assistants but without extra cash registers – long
queues would be a reflection of diminishing returns in this case.

Output (Q)
The output at which average costs
are at their lowest is known as the
technically optimum output, and is
output q1, in Figure-costs of production.
At this point the factors of production are
being combined so as to minimize unit
costs.
The change in total costs of
production as output is changed is
referred to as the marginal cost. Marginal
cost is correctly defined as the additional
cost incurred of
producing one more unit of output, though in practice it is often applied in general
terms of any appropriate increment in production, e.g. the addition to total
electricity generating costs of bringing into service the marginal power station.
19
Marginal costs in the short run will only depend on changes in variable costs
because fixed costs are unaltered. In the long run marginal costs reflect changes in
the total costs of production since all inputs are variable. Hence, when discussing
changes in output we need to distinguish the impact on marginal costs in the short
run and long run. Figure Marginal cost and output illustrates a typical relationship
between short-run marginal cost and output (the nature of the long-run marginal
cost is addressed later in a discussion of economies and diseconomies of scale).
Figure: Marginal cost and output
At the margin, as output is increased the additional costs of production will
tend to fall at first but rise as diminishing returns set in, as illustrated in Figure
Marginal cost and output. There is an important relationship between marginal and
average total costs as shown in this figure. As long as the marginal cost (MC) is less
than the average total cost (ATC) of production, then the latter must be falling.
Once marginal cost exceeds average total cost the latter will be rising. If you have
difficulty understanding this relationship think about the effect on the average
score of a sports team when the last player scores more or less than the average
scored by the previous players.
In Figure Marginal cost and output, the marginal cost curve fell and then rose.
However, empirical studies of firms suggest that sometimes marginal costs do not
vary greatly with the level of output but instead are broadly constant over a certain
range of output.
The flatness of the marginal
cost curve between outputs of q1
and q2 in Figure Constant
marginal costs means that
average variable costs remain
constant until around capacity
output is reached. Only variable
costs have a bearing on marginal
costs because fixed costs are
fixed. Often, of course, marginal
costs will start to rise before
absolute full capacity working is
reached as management tries to
squeeze out further output.

2.3.7 Economies and Diseconomies of Scale
In the long run, management decisions will be concerned with how production
costs change as the size of the business alters. Opening up new factories, offices
and shops is associated with a change in the scale of output. There are broadly
three possibilities as follows which may arise:
Constant returns to scale. This arises when the volume of output increases in
the same proportion to the volume of inputs.
20
Increasing returns to scale. This arises where the volume of output rises more
quickly than the volume of inputs.
Decreasing returns to scale. This arises where the volume of output rises less
quickly than the volume of inputs.
These three possibilities are associated with constant cost, decreasing cost and
increasing cost production in the long run respectively. For example, increasing
returns to scale should result in decreasing costs (whether or not costs do in fact
fall also depends on input prices).
The existence of increasing and decreasing returns to scale is explained by the
presence of both internal and external economies and diseconomies of scale in
production.
2.3.7.1 Internal economies of scale
Internal economies of scale arise in industries such as chemicals, oil
extraction, High street banking, etc., where there must be a large output to
minimize long-run average costs. Economies stem from the more effective use of
available resources resulting in higher productivity and lower costs. A number of
internal economies of scale can be readily identified in relation to the following:
Labour. Better use may be made of specialized labour and managerial skills in
large firms and there may be economies in firms can often attract and fully
utilize better quality staff. In addition, a superior division of labour may be
achievable, which is likely to lead to the development of expertise on the part of
staff and a consequent growth in overall productivity.
Investment. There is likely to be a minimum level of investment which is viable
in many businesses – a firm cannot buy half of a computer even though it may
only require that much computing capacity! Investment economies of scale are
likely to be more evident in large – rather than small-scale enterprises.
Procurement. Large firms have muscle and are more likely to be able to gain
cost savings through bulk purchasing. This is particularly evident in grocery
retailing, for example in the United Kingdom where the market is dominated by
a small number of supermarket chains, namely Tesco, Sainsburym Gate-way,
ASDA and Argyle (Safeway and Presto) which are able to exercise considerable
bargaining power over grocery producers. A firm which purchase all or most of
a supplier’s output will be able to exert considerable monopsony (i.e. dominant
buyer) power and drive down price.
Research and development. In industries such as aerospace and
pharmaceuticals the pursuit of competitive advantage requires heavy
investment in R&D. To be viable, the cost must be spread over the very large
output which only large-scale enterprises can hope to achieve.
Capital. Large firms can often raise loan finance more easily and cheaply than
smaller businesses since they usually offer greater security to lenders. Also,
many larger firms are publicly quoted and hence have access to the equity
market.
21
Diversification. Many large firms spread risk by operating in a number of
different markets. For example, ICI supplies paints, fertilizers, pharmaceuticals
and so on. A collapse of one market should not, therefore, jeopardize the whole
company.
Promotion. Large firms are likely to be able to make more effective use of
advertising, specialist sales forces and distribution channel.
By-products. In large enterprises such as oil companies, the opportunity exists
to produce a wide range of by-products in quantities which are commercially
exploitable.
2.3.7.2 External economies of scale
Internal economies of scale relate to the operations and decisions made by the
individual firm. They are therefore directly under the control of the firm’s
management. In contrast, external economies arise at the industry level and are
generally associated with growth over time in the industry. Three main types of
external economies may arise relating to the following:
Labour force. Where firms in an industry group together there is often a large
and skilled labour force in the locality which all firms can utilize.
Suppliers. As an industry grows, it is often the case that specialized ancillary
firms become concentrated in the locality, supplying components, transport,
consultancy services, etc. For example, with the development of the financial
services industry in London, it is not surprising that there is also a
concentration of accountancy and legal advisory services (as well as wine
bars!).
Social infrastructure. A concentration of industry in a particular area will also
lead to the development of educational and training facilities, roads, rail
networks and a greater availability of housing for workers, all of which may
help to reduce industry’s costs. Indeed industry and government often
cooperate to ensure that these facilities are developed in areas of business
expansion, e.g. through new town developments and regional expansion
schemes.
2.3.7.3 Internal diseconomies of scale
A growing firm is likely to benefit from economies of scale which are internal to
its operations. However, as growth continues a point may be reached where certain
internal diseconomies of scale arise. These result in rising long-run marginal and
unit costs. Once this occurs the firm needs to consider whether or not further
expansion is desirable. Such diseconomies may relate to the following:
Management. The larger a firm’s operations become, the more complex the
managerial structure often needs to be. There is a danger that management will
become bureaucratic and unresponsive. This leads to ‘organizational slack’ and
the internal decision-making process slows down as staff becomes alienated.
The firm may also become less responsive to changes in the external market.
How often do we hear the criticism that a firm has ‘too many layers of
management’ resulting from inadequately managed growth?
22
Labour. It is a well-known fact that industrial disputes are more likely to occur
in large rather than small companies. This arises because, as the labour force
grows, the gap between ‘management’ and ‘the workers’ grows and
consequently loyalty to the firm falls. At the same time unionization increases
and this can bring with it more rigid wage-bargaining processes leading to
friction between management and workforce. Costs may rise because of lowered
productivity and the need for greater managerial supervision. Absenteeism and
slacking in work also tend to be more prevalent in large firms.
Other inputs. As the firm grows its demand for inputs increases. If the supply
of these inputs is limited then their unit cost will rise as the firm’s output
expands. This applies not only to materials and components but to certain
skilled labour requirements.
2.7.3.4 External diseconomies of scale
Sometimes costs rise as the whole industry expands in a particular area.
Growth can put pressure on the price of housing and transport and this may
ultimately feed through to higher wage demands and increased distribution costs.
There may also be additional costs associated with congestion and other
environmental hazards.
PRODUCTION COSTS IN THE LONG RUN
As firms expand production over the long run and move to different scales of
operation, if internal and external economies of scale exist unit costs will fall as the
volume of output increases. This represents increasing returns to scale or decreasing
cost production as defined above. Presumably, however, unit costs will not always
decline (otherwise they would eventually approach zero) and hence we would expect
them eventually to level out. The firm is then said to operate under constant cost
production. It is conceivable that at some very large output internal and external
diseconomies of scale might cause unit costs to rise, leading to increasing c ost
production. These three possibilities – increasing, constant and decreasing returns to
scale are illustrated in Figure The long-run average cost curve.

The art of good management is to
capture the benefits of internal and
external economies and, of course, to avoid
the onset of internal and external
diseconomies. Ideally, firms will want to
operate at the level of output which
corresponds to minimum units costs over
the long run or what is sometimes termed
the minimum efficient scale (MES). This
represents the technical optimum scale of
production for the firm. In Figure The long-
run average cost curve an output of at least
q1 must be achieved to minimize long-run
average costs and hence this is the MES.
23
As there is constant cost production between outputs q1 and q2 there is no
single optimum scale – instead, any of the outputs in this range represents a
technical optimum. However, if the long-run average cost curve were U-shaped
there would be one scale of output, at the bottom of the U, which represented the
technical optimum. Achieving MES gives a firm a strong competitive advantage in
the market place over higher-cost producers.
Clearly, management must strive to avoid long-run average costs rising. As
one of the major diseconomies of large-scale production is managerial breakdown,
firms have tended to establish sub-units, separate operating companies and so on
to avoid this.

3.3.1 The Analysis of Consumer Demand
A firm is unlikely to make adequate profits, and hence remain in business for
very long, unless it has a reasonable knowledge of the demand conditions facing it
in the market place. Complete ignorance of these conditions means that it will have
not clear basis – other than guesswork – for deciding how much to produce, what
quantity it can expect to sell, and at what price. By contrast, the successful firm
plans effectively how to allocate its resources so that it can respond positively to
any changes in the demand for its products. For example, it will hold sufficient
finished stocks and maintain an adequate stream of work in progress to meet
expected surges in demand.
In this lesson we develop a number of economic concepts which are useful to
an understanding of consumer behaviour. The key aim is to identify the forces that
determine the demand for a firm’s product and to show how management can
proceed to measure the magnitude and impact of these forces. Therefore, much of
what is presented in this chapter provides a foundation for various aspects of
business management. For example, if management can estimate the importance of
25
factors such as price, advertising or the rate of interest in determining the quantity
demanded, then this will help in a planning useful marketing strategy. At the same
time, if it is possible to predict (albeit with some margin of error) the volume of sales
that can be expected when one or more of these factors is altered, this will have
important implications for the firm’s overall financial and business strategies.
Some of the factors affecting the demand for a firm’s product are under the
direct control of management (such as the advertising spend) while other factors
that influence demand are external. External factors include consumers’ incomes,
the prices charged by competitors, demographic trends and changes in the weather.
As they lie outside the firm they may be described as ‘uncontrollable’ conditions of
demand. Business planning should nevertheless incorporate some estimate of how
these forces might change in the future and what the ultimate impact of possible
changes will be on sales. We shall focus on the measurement and determination of
demand, linking the concepts introduced in this chapter to the determination of
revenues received from sales and to the overall structure of the industry in
question. This provides a useful introduction to the more detailed analysis of
market structure and the nature of competition.
Much of what is presented in this lesson represents a simple and practical
approach to understanding demand, based on a theoretical foundation developed
by various economists over many years. various models of consumer behaviour
have been put forward by economists insights into the decision-making process of
consumers. However, they all draw on the (common sense) observation that
consumers, when spending their hard-earned money, attempt to increase their
utility (i.e. overall satisfaction from their limited budgets). In other words, it is
(realistically) assumed that all consumers are rational in that they desire to
maximize their own well-being.
In this lesson the following central concepts are discussed:
The market demand curve.
Consumer surplus.
The determinants of demand.
The classification of products.
Concepts of elasticity.
The relationship between price elasticity and sales revenue.
When economists discuss the ‘demand’ for a product, they mean the effective
demand, that is, the amount consumers are willing to buy at a given price and over a
given period of time. Demand, in the economists’ sense, does not mean the wants,
desires or needs of people since these may not be backed up by the ability to pay (you
may want a Jaguar motor car but, unless you actually go out and buy one your desire
will have no bearing on the demand for Jaguar cars!). Mangers refer to demand in the
same way, hence readers should have no difficulty with this treatment.
26
At any given time and for any good or service it is possible to perceive of a
consumer’s demand curve.
A Consumer’s demand curve relates the amount the consumer is willing to buy
to each conceivable price for the product.
Clearly, we would expect the consumer to be willing to buy more of something
the lower its price. From the notion of a relationship between an individual
consumer’s demand for a product and its price we can derive the total demand of
all consumers in the market – the latter in turn gives rise to the notion of an
aggregate or market demand curve for a product.
The market demand curve is derived by summing the individual demand curve
of consumers horizontally.
A market demand curve is shown in Figure Derivation of the market demand
curve. DADA represents the demand for the product by Kumar at various price levels
while DEDE represents the corresponding demand by Kavitha. Summing
horizontally it will be seen that, for example, at price P1, a total quantity of Q(A + E) is
demanded, which is equal to the sum of the individual quantities demanded,
QA and QE, at that price.
3.3.2 THE LAW OF DEMAND
Product demand curves, both individual and market, show the relationship
between different possible prices of the good in question and the quantity of the
good which we expect to sell.
In general there is a central law of demand, which states that there is an
inverse relationship between the price of a good.

Figure on Derivation of the market demand curve and the quantity demand assuming
all other factors that might influence demand are held constant
Thus, if price increases, it is normally the case that less will be bought (and
vice versa). In other words, a rational consumer prefers to pay less rather than
more for something. In this respect we think it is safe to assume that most
27
consumers are rational! Economists are sometimes criticized for assuming
‘consumer rationality’, but at least in terms of the way in which it is presented here,
it does not seem to be an outlandish assumption about consumer behaviour.
It is important to be aware of the significance of the expression assuming all
other factors that might influence demand are held constant’. Economic activity is
complex and usually more than one thing is changing at any given time. For
example, at the time a firm is changing the price of a product household incomes
may also be increasing, advertising expenditure may be rising, consumers may be
revising their attitude to the product and so forth. In order to study the relationship
that exists between price and demand, it is necessary to ‘freeze’ the picture. We can
then later study how behaviour changes as we introduce other factors which might
impact on demand, step by step. The assumption of all other factors held constants’
is therefore, merely a convenient framework to begin the study of what we accept is
a much more complex relationships in practice. The assumption is often
abbreviated and stated in its Latin form as ceteris paribus. Also, by initially
examining how demand changes only in relation to changes in price we are able to
illustrate the demand relationship in a simple, two-dimensional, diagram.
We stated above that if price increases, demand normally falls (and vice versa).
The word ‘normally’ is very important and later we shall examine cases where the
law of demand may not apply. For the moment, however, we shall assume that the
demand curve is downward sloping from left to right, with price measured on the
vertical axis and quantity demanded on the horizontal axis as shown by the line DD
in Figure Linear and non-linear demand relationships. Note that if price is
continuously increased, a point must eventually be reached where nothing will be
demanded, point ‘P’ in Figure Linear and non -linear demand relationships.
Likewise, management will eventually discover that the only way it can sell more is
to give the good away (i.e. charge a zero price – point q’ in the figure)! The line DD in
Figure Linear and non-linear demand relationships is referred to, generally, as a
demand ‘curve’, despite the fact that in this diagram it is shown as a straight line.
Economists frequently use linear demand curves as approximations for true
relationships between price and demand which may in fact be non-linear (such as
D’D’ in Figure Linear and non-linear demand relationships). This is purely for
convenience and illustration in text books, though over small sections of the curve
a linear representation will often provide a close enough approximation to predict
actual demand in many practical applications.
3.3.3 The Determinants of Demand
As we have stated above, the study of consumer behaviour generally shows
that as the price of a product falls, consumers will choose to buy more of it, Ceteris
paribus. However, a change in the price of the good itself is only one determinant of
the total quantity of the good demanded. A listing of the most important factors
which affect demand might include the following:
The ‘own price’ of the good itself (Po).
The price of substitute goods (Ps).
The price of complementary goods (Pc).
28
The level of advertising expenditure on the product in question, as well as
on complementary and substitute products (A).
The level and distribution of consumer’s disposable incomes ( Y ), i.e.
income after state direct taxes and benefits.
Changes in consumers’ tastes and preferences (T).
The cost and availability of credit (C).
Consumer’s expectations concerning future price rises and availability of
the product (E).
Changes in population, if we are examining the total market demand (POP).
In relation to particular products some of these factors may be more important
as determinants of demand than others. The factors other than ‘own price’ which
affect demand may generally be described as representing the conditions of demand
(i.e. the ‘environment’ within which consumers decide how much to purchase at
any given price). We can summarize these conditions in a demand function, which
in shorthand notation express the quantity demanded of a product (Qd) over a given
time period, as:
Thus, the demand curve (either DD or D’D’) in Figure Linear and non -linear
demand relationships shows the quantities of the good in question that will be
bought (Qd) at different prices (Po) with all other factors in the demand function held
constant. Clearly, as Po changes, there will be a movement along the demand curve,
say from A to B (in the case of a price rise) or B to A (in the case of price fall).
However, if any of the other factors in the demand function should change, then
there will be a shift in the demand curve as illustrated in Figure Shifts in the
demand curve. This highlights, the fact that, as the conditions of demand change
(except for PO, the ‘own price’), there will be a new price-quantity relationship
established. For example, a population boom is likely to mean that at any given
price, PO*, more will be demanded over time, shown by the increase from Q1 to Q2
in Figure Shifts in the demand curve.

The distinction between a movement along a product’s demand curve and a
shift in the curve is useful because it helps to identify the causes and nature of
changes in demand.
When the own price changes, the outcome is a movement along the demand
curve and when any other determinant of demand changes, there will be a shift of
the demand curve (either to the left, showing a fall in the quantity demanded, or to
the right, showing a rise, depending on the nature of the change).
Some examples of shifts in demand curves are presented in Figure Changes in
conditions of demand.
3.3.4 The Classification of Products
There are two distinct reasons why more of a good is usually demanded as its
price falls (and vice versa). These are referred to as the ‘income effect’ and the
‘substitution effect’ as follows:
The income effect. As its own price falls, consumers are in effect better off
and hence able to buy more of the good. The fall in price has raised their
effective purchasing power, while the opposite applies in the case of a price
rise. The change in price is equivalent, in effect, to a change in income (though
actual income is unchanged).
The substitution effect. As the price of a product falls, it becomes relatively
cheaper than alternatives. Hence, there is a natural tendency for consumers
to switch towards the product in question, substituting more of it for other
goods. The opposite outcome occurs of course, where there is a rise in the
price of the product.
The substitution effect on demand of a price change will always be opposite in
direction to the price change (assuming rational behaviour on the part of
consumers) or zero if no substitutes exist at al. The income effect, however, can
either increase or reduce demand depending not only on the direction of the income
change but on the nature of the good or service. The direction of the income effect
allows us to classify the nature of products under the following particular headings:
Normal products. Goods and services may be classified as ‘normal products’
if the quantity demanded rises as income rise and falls as incomes fall. Here,
as throughout the rest of the chapter, income refers to a change in real
purchasing power rather than simply a nominal change which may be
neutralized by a proportionate price change. For example, family cars would
be classified as ‘normal’ since as household incomes rise (in real terms), the
demand for such cars also generally rises. Note that the key factor is the link
between demand and income – we would still expect an inverse relationship
between price and quantity demanded.
Inferior products. Certain products are classified as ‘inferior’ because the
demand for them falls as incomes rise (and vice versa). For example, as
household incomes rise, there may be a tendency to switch from buying
30
cheaper, lower quality meats to buying Grade A beef. The switch from inferior
to superior products is common as real incomes rise over time. For most
inferior goods, however, there is still likely to be an overall increase in demand
as their price falls. This is because the positive substitution effect (i.e. a switch
towards the relatively inexpensive product) more than offsets the negative
income effect on demand.
Giffen Products. A special case of the inferior product arises when as price
rises, more of the good in question is bought – resulting in an upward sloping
demand curve, contrary to the normal law of demand. Such products are
classified as Giffen products, named after a nineteenth-century English
economist who studied the response to changes in the price of potatoes in
Ireland. Giffen found that as the price of potatoes rose, the Irish at that time
bought more since they could not afford to buy as much of the more expensive
foodstuffs such as meat. This response to a price change is still found today in
many developing countries – as the price of rice rises, people are forced to buy
less meat and fish in order to be able to continue buying sufficient quantities
of rice to stay alive – hence the vicious circle of famine and malnutrition found
common in many parts of Africa

32
In the case of Giffen products, the income effect of a price change is so large
that it swamps the substitution effect, leading to an overall rise (fall) in demand for
the product as its price rises (declines).
Veblen products. It has also been suggested that ‘luxury type’ products also
display perverse price-demand relationships, though for different reasons to
that of the Giffen products case. These are sometimes referred to as Veblen
products, after the American economist, Thorstein Veblen (1857-1929), who
explored the phenomenon. For example, as the price of a piece of jewellery
rises, the demand for it may also rise as consumer attach a ‘snob’ value to
owning and displaying expensive items. Equally, all the price falls there is the
possibility that the product could lose its up-market image – ‘everyone can
afford it, so why bother to buy it’! This situation reflects a change in tastes,
determined by the perception of the product in relation to its price. The
existence of a positive veblen effect is, of course, very advantageous to the
producers concerned since it enables them to charge premium prices for their
products.
3.3.5 Concepts of elasticity
The discussion so far has been concerned with the broad direction of
relationships between price changes, changes in other possible determinants of
demand and the quantity demanded. However, in addition to understanding the
nature of demand, it would of course be very useful if management were able to
estimate the extent to which demand is likely to respond to a price change. Gauging
this responsiveness is referred to by economists as the measurement of price
elasticity. In addition, since, as we have seem, demand is affected by many factors,
we can calculate elasticity (i.e. responsiveness of quantity demanded) wi th respect
to a wide range of variables other than price, notably the price of other goods and
income. Thus we can define the following:
Price elasticity of demand
This measure the responsiveness of quantity demanded of a product to
changes in its ‘own price’. For example, if the price of alcohol increases, what
happens to the quantity of alcohol demanded?
Cross elasticity of demand
This measure the responsiveness of quantity demanded to changes in the
prices of other goods (both complements and substitutes). For example, if the price
of one brand of coffee rises, what happens to the demand for another coffee brand?
Or, if the price of petrol falls, what happens to the demand for cars?
Income elasticity of demand
This measures the responsiveness of demand to change in the real income of
consumers. For example, if real income are rising, on average, by £100 per month,
what will happen to the demand for housing?

In general terms, a coefficient of elasticity can be calculated for each of the
above categories using the following general formula:
We will now examine each of these three elasticity concepts in more detail.
Price elasticity of demand
Based on the general formula, the (own) price elasticity of demand for a
product may be defined as:
Where a product has a downward sloping demand curve (the usual case), the
value of the price elasticity of demand will always be negative – since when price
rises demand falls and when price falls demand rises. Conventionally, however, the
negative sign is omitted when the value of elasticity is stated and we follow the
convention in the following discussion.
Two different types of price elasticity (Ed) can be calculated as follows:
Arc elasticity of demand, and
Point elasticity of demand.
Arc elasticity of demand
Coefficient of elasticity = ariablerelevant v in the change Percentage
demandedquantity in change Percentage
Ed = product theof price in the change Percentage
demandedquantity in change Percentage
34
With reference to Figure Arc elasticity of demand, arc elasticity measures the
responsiveness of demand between two points on the demand curve such as X and
Y, whereas, as the name suggests, point elasticity is concerned with the elasticity at
only one given point of the curve. Since managers are usually concerned with
estimating the effect on demand of, say, a 5% rise in price, the price change causes
a movement along a section of the demand curve and hence the arc elasticity
formula is the one that is often used for practical purposes.
Using the notation shown in Figure arc elasticity of demand we can calculate
arc elasticity as:
O Q
P
Y
X
Q1 Q2½ (Q1 + Q2)
½ (P1 + P2)
P1
P2
Arc elasticity is measured at
midpoint between X and Y; i.e.,
at 1/2 (Q1+Q2) and ½ (P1+P2)
Quantity Demanded
It is important to appreciate the reason why arc elasticity is expressed on the
basis of the average quantity, ½ (Q2 + Q1), and average price, ½ (P2 + P1). When
there is an appreciable price change, the value of elasticity calculated on the basis
of X as the starting point will differ from that calculated on the basis of Y as the
starting point – we end up with two different values for the sensitivity of demand to
price changes which will not be very useful in business decisions. Using the
midpoint, however, ensures that price elasticity is the same regardless of the
direction of movement on the demand curve and, since it is based on the average
price and average quantity, it will be closer to the true estimate of elasticity over the
price range than that based on either of the two extreme points.
Point elasticity of demand
It should be intuitively clear from Figure Arc elasticity that as X and Y come
closer together, the arc shrinks in size and the two values for elasticities calculated

at X and Y separately will get closer to each other. If the distance is negligible, the
arc will end up as a single point and the arc elasticity calculation can be replaced
by that for point elasticity.
While point elasticity is expressed here in relation to Q1 and P1 it will be
appreciated that since the difference between Q1 and Q2 and P1and P2 will be
infinitesimally small, it no longer matters whether we use the ini tial or final price
and quantity values. In business, of course, management is unlikely to be
interested in ‘infinitesimally’ small changes in price since it is impractical to
introduce, say, a 0.0001% change in the retail price of most products.
The term ‘elastic’ and ‘inelastic’ are often used to describe different degrees of
elasticity. In general (and ignoring the negative sign):
Products with a price elasticity of demand of less than 1are said to have a
relatively inelastic demand with respect to price – they are said to be price
inelastic.
Products with a price elasticity of demand greater than 1 are said to have a
relatively elastic demand – they are said to be price elastic.
Products with a price elasticity of demand equal to 1 are said to have a unit
elasticity of demand.
Irrespective of the precise method of calculation, the value of the resulting
price elasticity of demand will vary depending upon the nature of the demand for
the good in question. In Figure Degrees of elasticity of demand the fol lowing three
extreme price elasticities are illustrated (a, b and c) together with a representation
(d) of the elasticities along a down-ward sloping demand curve.
Perfectly inelastic demand: When the demand for a product is entirely
unresponsive to any change in price, the demand curve will be a vertical line as
shown in Figure Perfectly inelastic demand with Ed equal to zero at every point.
This is referred to as a perfectly inelastic demand.
Perfectly elastic demand: Where the demand curve is horizontal, any
quantity of the product can be sold at a certain price, P1, as in Figure Perfectly
elastic demand. Demand is said to be perfectly elastic with a value of infinity at this
price. Any increase in the price, no matter how small, will result in none of the
product being sold. If the price is reduced, even marginally, demand (theoretically)
becomes infinite.
Unit elasticity of demand: A further special case arises when the shape of
the demand curve is a rectangular hyperbola as in Figure Unit elasticity of demand.
At any point on it the value of elasticity is equal to unity.

The three cases above are, in practice, rarely found and should be treated as
theoretical benchmarks for an analysis of actual price elasticities. Small stre tches
of a demand curve though may closely equate to one or other of these extremes.
Figure Range of elasticity shows a situation where the value of elasticity varies
between zero and infinity along its length with a value of 1 at the midpoint. It is
important to appreciate that (excluding the cases of vertical and horizontal demand
curves) even where a product has a linear demand curve, its elasticity changes as
price is altered. This follows because the original price and quantity figures, which
enter into the elasticity calculation (see above). This means that price elasticity
must be recalculated for every price change. If the price elasticity was, say, 0.6
when the price was last increased by 5%, even if in the meantime none of the
conditions of demand have altered – i.e. the demand curve has not shifted (which in
itself is most unlikely) – a further 5% increase in price is likely to be associated with
a price elasticity above 0.6.
Given that the price elasticity of demand is a numerical measure of the
responsiveness of quantity demanded to changes in price, there is obviously a
relationship between the value of the elasticity and the total sales revenue received
by the firm. This has important implications for pricing strategy and we shall return
37
to it later in this chapter. First, we introduce the other elasticity of demand
measures noted earlier, namely cross-price and income elasticity.
Cross-price elasticity of demand
Cross-price elasticity of demand (sometimes simply referred to as ‘cross-
elasticity’) indicates the responsiveness of the demand for one product to changes
in the prices of other goods or services. The concept has most relevance where there
are obvious substitute or complementary commodities and it is, therefore, of key
importance to businesses which face major competition or whose sales vary directly
with the sales of other goods, e.g. mortgages and mortgage protection insurance.
If A is the good or service we are interested in and B is the other product
whose price is altering. We can calculate the value of the cross-price elasticity of
demand for A with respect to B as:
In the case of substitutes, the resulting figure will be positive since a fall in the
price of a substitute will lead to more sales of the substitute and hence a fall in the
demand for the other product being considered. In the case of complementary
products, the resultant value will be negative. If the demands for the two goods
appear to be unrelated then, of course, the cross-price elasticities between them
can be expected to be negligible or zero.
The terminology regarding the degree of cross-price elasticity (ignoring the
sign) is the same as for price elasticity namely:
1 = unit cross-price elasticity.
Less than 1 = inelastic cross-price elasticity.
Greater than 1 = elastic cross-price elasticity.
3.3.6 Income elasticity of demand
As noted earlier, demand is also likely to be responsiveness to factors other
than ‘own price’ or the price of complements and substitutes. One important factor
is real income (i.e. nominal income adjusted for inflation). Empirical studies usually
define nominal income in terms of either household disposable income (i.e. house -
hold income after income tax, and other direct taxes, plus welfare state payments
have been incorporated) or gross national income. Income elasticity of demand is
defined as:
The value of the income elasticity will usually be positive, suggesting that more
is bought as real income rises, though for certain products it may be negative as we
Income Ed = income realin change Percentage
demandedquantity in change Percentage
Cross-price Ed = b of price in the change Percentage
demandedA ofquantity in change Percentage
38
saw earlier, albeit in a slightly different context. The actual values of income
elasticities can be used to classify products into the following two broad categories:
Inferior goods: These are goods of which consumers buy less when real
incomes rise. The value of income elasticity is, therefore, negative. Examples might
be potatoes, Lada cars, cheap package holidays, etc.
Normal goods: These are the most common goods with demand generally
rising as real income rises. They can themselves be further subdivided into two
categories:
Necessities: These are goods and services which exhibit a positive income
elasticity of demand, though the value will tend to be less than 1. Articles such as
basic foodstuffs and ordinary day-to-day clothing fall into this category. Consumers
will purchase a certain amount of these goods at very low levels of income, but they
will tend for any given percentage increase in real income to increase their spending
on the goods by a smaller proportion.
Luxuries: At very low income levels, nothing will be spent on these but, once a
certain threshold level is reached, the proportionate rise in demand for luxury
goods is greater than the proportionate rise in real income, e.g. foreign holidays,
eating out and video recorders.
From the above classification it is obvious that it will pay firms which want to
expand output to concentrate on selling products with high income elasticities
when living standards are rising. With greater purchasing power, people will tend to
buy disproportionately more luxury-type goods. On the other hand, firms producing
goods with low income elasticities will tend to face a more stable market for their
products and will be less affected in times of economic downturn. The food retailing
industry is usually an example of this.
3.3.7 The relationship between price elasticity and sales revenue
In addition to income elasticity, a firm’s fortunes will also be affected by price
elasticity as demand, and hence the firm’s revenue, changes as a result of price
changes. The total receipts or total revenue (TR) earned by a business from sales is
calculated by multiplying the total output sold (Q) by the average unit price (P), i.e.
TR = P X Q. The resulting value of total revenue is illustrated by the shared area in
Figure Demand and total revenue with price at P1 and quantity demanded equal to
Q1. Where there is unit elasticity of demand, as the price is varied the total revenue
earned from sales remains unchanged. For example, a 1% fall in price will bring
about a 1% rise in sales, leaving total revenue unaltered. However, as we indicated
earlier, unit elasticity is an extreme case and unlikely to be found over more than
modest stretches of a demand curve. It will usually be the case that the value of
elasticity will vary along the demand curve, as shown earlier in Figure. As price
changes by a certain proportion, the quantity demanded usually changes by a
greater or lesser proportion.

Quantity demanded
Figure: Demand and total revenue
In general, we can derive the following rules:
With a price inelastic demand:
An increase in price causes a reduction in quantity demanded, but total
revenue increases;
A fall in price causes an increase in quantity demanded, but total revenue
earned declines.
With a price elastic demand:
An increase in price causes such a large fall in sales that total revenue falls;
A reduction in price causes such a large increase in the quantity demanded
that the total revenue rises.
Hence, it is clear that accurate estimates of price elasticity are vital to
business decision-making. Putting this way, ignorance of the market response to
price changes is likely to be a recipe for disaster!
The link between total revenue and price elasticity results from the fact that,
faced with a downward sloping demand curve for a product, management must
lower price if they want to sell more (other factors held constant). But if extra sales
compensate for the lower unit price then total revenue will not decline. Similarly,
management might raise the price of a product to raise revenues, but the resulting
collapse of demand may actually cause total revenue to contract. In other words,
the precise responsiveness of demand to a price change determines the effect of a
price change on revenue received. This introduces another important concept which
40
will be used throughout much of the remainder of this book, namely marginal
revenue.
3.3.8 Marginal Revenue
Marginal revenue is defined as the change in total revenue as a firm sells one
more or one less unit of its output. The size of a ‘unit’ will vary from firm to firm –
for example, the smallest unit of water which is charged to domestic users is likely
to be much more than a single litre, while the car dealer may be concerned with the
sale of a single car. To be mathematically correct, marginal revenue is the increase
in total revenue resulting from an infinitesimally small change in quantity sold. But
it can be approximated by looking at the change in total revenue resulting from a
small, quantifiable, change in output.
In the figure on the relationship between elasticity, total revenue, marginal
revenue (MR) and the demand curve (D). The demand curve is also the average
revenue (AR) curve because it shows the price at which each unit is sold. Provided
that when units are sold they are all sold at the same price, price and average
revenue must be identical.
The key points to note are as follows:
The marginal revenue curve declines at twice the rate of the demand (average
revenue) curve. Hence, the marginal revenue curve cuts the horizontal axis at a
point mid-way between the origin and point C in the Figure Elasticity, marginal
revenue and total revenue. A proof of this mathematical relationship is given at the
end of the chapter.
When total revenue is increasing, marginal revenue is positive. This results
from the fact that demand is elastic between points A and B on the demand curve
DD in Figure about Elasticity, marginal revenue and total revenue.
Total revenue is maximized when marginal revenue is zero which occurs when
the price elasticity is unitary. Therefore, further attempts to increase total revenue
by lowering price below P* will fall since sales volume will not increase sufficiently
to compensate for the price fall.

Marginal revenue is concerned with changes in total revenue resulting from
small changes in sales. Since many business decisions hang on whether to increase
or reduce sales, t concept of marginal revenue is central to much of the discussion
relating to business decision-making in subsequent chapters. It is important,
therefore, that the reader should not proceed further until the concept is fully
understood.

sharp fluctuations in price.

Explanation: the consumer seeks maximum satisfaction from limited income.
Other things being equal, a fall in price of a good increases the satisfaction per
penny spent on it above that available from other goods. The consumer will
increase demand for the cheaper good and cut demand for the other goods.
Changes in the price of the good are reflected by a movement along the
demand curve: a different quantity is demanded at the new prices.
A shift in the demand curve results from changes in the following other factors
influencing demand.
The price and availability of substitutes (eg tea and coffee)
The price and availability of complements (eg CD players and CDs)
The size of household income and, in some cases, the cost and availability of
finance or credit, eg with owner-occupied housing and spending on credit cards
Tastes, fashions, attitudes towards a good
Consumer expectations about future market conditions (eg expected price rises
or supply shortages)

The supply curve (again, price plotted against quantity) represents estimates of
the quantities of a good that firms in the industry will want to supply to the market
per time period at different price levels.
Firms will want to supply more at higher prices, and so supply curve slopes
upwards from left to right. A change in price is reflected by a movement along the
supply curve.

The marginal costs of producing the good. (A market supply curve represents
the marginal costs of production for the industry as a whole)
The prices and costs of making other goods that firms could switch to making
instead

In a free and stable market, the forces of demand and supply will interact so
that an equilibrium (‘market clearing’) price and quantity will be reached. This is
where:
The quantity demanded equals the quantity that firms want to supply (Q in
the diagram above), and so
All production output is purchased by consumers at the market price (P), and
there are no market pressures for a change in price or quantity
Firms now want to supply more of
the good at any given price –

producing the good have
fallen.

4.6 SUMMARY
In nutshell this part of the lesson introduced how the prices of goods and
services are determined using the basic factors ‘demand and supply’ of goods and
services. The law of demand introduces the relationship between price and
quantity demanded. Demand for a good tend to alter from time to time. If the
alteration in demand is due to ‘price’ it is ‘change in demand’. If the demand
change due to the reasons other than ‘price’ it is shift in demand. The concept
‘elasticity of demand’ is a measure to know the extent of change in demand and
supply with respect price, income and prices of related goods. The nature and
degree of responsiveness vary with respect to nature of good in question

PRICING UNDER DIFFERENT MARKET CONDITION
5.1 INTRODUCTION
This part of Economics introduces the Nature of the mechanism of exchange of
goods and services through price determination in a market. Under perfect
competition and monopoly models have proved useful for predicting behaviour in
the market. We understand about the monopolistic competition

5.3.1 The firm Maximizing Profits
For the firm in perfect competition or monopolistic competition, for the
oligopolistic and the monopolist, the profit-maximising condition is the same.
Marginal cost (MC) = Marginal revenue (MR)
You need to understand each model of market structure – perfect
competition, monopolistic competition, and monopoly. Pay attention to
the significance of the number of firms, the nature of the product and the
ease of entry and exit in the industry.

From position Q1 in the diagram above, the firm will expand output to Qm
since the extra revenue it gets from selling the additional units of output exceeds
the extra cost it incurs in producing and selling the additional units.
Higher levels of output are not attractive because the firm will make a loss on
the additional units (MC > MR), reducing overall profits.
In the short term:
A loss-making firm might stay in the market, hoping that in the longer term,
prices will go up or costs will fall
A firm might earn supernormal profits (defined in the last section of Chapter 7
above), even in a competitive market
A firm might succeed in eliminating or reducing competition, or might be
protected from competition, by barriers to entry
Barriers to entry determine the number of sellers in a market, and include the
following:
Patents and copyrights
Government legislation creating/protecting a monopoly
A natural monopoly (economies of scale)
The high costs of getting established in the market (entry costs)
In the short run, the threat of price cuts and a price war (predatory pricing)
Firms will try to earn supernormal profits if they can. However, competition
erodes supernormal profits, and firms may have to be satisfied, when equilibrium is
reached in the long run, with just normal profits.
Equilibrium changes when circumstances change – eg a shift in market
demand or supply.
A firm is in equilibrium when it is maximizing its profits, and can’t make
bigger profits by altering the price and output level for its product or service
An industry is in equilibrium when the following apply
53
Supply and demand are equal at a certain price and output level
There are no firms trying to get into the market
There are no firms trying to get out of the market
5.3.2 PERFECT COMPETITION
Perfect competition refers to a situation in which all firms in the market are
price takers, because they do not have the ability to influence the market price, and
must accept the ruling market price for their product.
The perfect competition model provides: a benchmark against which to
measure the efficiency of other market structures.
Assumptions of perfect competition are as follows.
A large number of buyers and sellers
Producers and consumers acting rationally and possessing the same
information
Homogeneous product
Free entry of firms into and exit out of the market
No transport costs or information-gathering costs
A firm’s demand curve (= price = average revenue or AR curve) differs
according to the type of market the firm is in.
A perfectly competitive firm must accept the ruling market price, and can only
sell its output at that price (AR = MR). This contrast with a price -making firm,
which faces a downward sloping demand curve

If MR > MC in the short, run, firms earn supernormal profits and, under
conditions of perfectly competition, prices will be bid down as new firms enter the
industry and market output rises.
In the long run under perfect competition, normal profits only are earned when
MC = MR, since AC = AR. MC = MR = AR = AC.
To illustrate the position of a price-making firm in an exam answer, a
straight line demand curve can usually be drawn, for simplicity. The MR
curve can then be drawn as a straight line too, cutting the x axis (output
axis) half-way between the origin of the graph and the point where the AR
curve cuts the x axis.

Imperfect competition refers to a situation (such as monopolistic competition,
oligopoly or monopoly – each considered below) in which one or more firms are
price makers, and can have some choice in deciding the price at which they will sell
their product.

Assumptions of pure monopoly are as follows.

Barriers to entry exist

Monopoly Equilibrium
The monopolist’s demand (AR) curve is the industry demand curve.
Where profits are maximized (MC = MR), usually AR > AC and therefore
supernormal profits are earned.
Profits are maximized at output level Q below where AC is minimized
(allocative inefficiency).
Supernormal profits can encourage a firm to become inefficient and wasteful of
resources. This is called X-inefficiency.
55
Possible points in favour of pure monopoly are as follows.
Economies of scale can be achieved
Monopolists can afford to pay for research and development out of
supernormal profits
Monopoly may be more stable than perfect competition
5.3.4 Monopolistic Competition
Product differentiation distinguishes a perfectly competitive market from a
monopolistically competitive market. For instance how producers of pen
differentiate each Varity they make, from the existing ones that are selling in the
market at time.
Detergents, toilet soaps, tooth brushes, beverages and pens we use are the
examples for the goods that are the examples of differentiated products, thought
they are meant for similar use.
Even though there are many firms in a monopolistically competitive market,
the demand curve faced by any one firms slopes downward because each product is
slightly different from all other products, each firm is like a mini monopoly—the
only producer of that specific product. The downward slope reflects the
differentiated nature of the products: the products are not perfect substitutes
(identical goods) as in the case of perfect competition.
Thus, the firm in monopolistic competition is a price maker. As the price of
“X” brand beverage is increased, when other things remains the same, consumers
switch to other beverages and the quantity demanded of “X” brand falls, but not to
zero.
The perfect competition and monopoly models have proved useful for
predicting behaviour in markets in which there are very large numbers of suppliers
or one supplier respectively. Many markets today, however, do not accord with
either of these extremes. Perfect competition assumes homogenous products, but
even where there is a large number of suppliers to a market there is often some
brand “loyalty” so that suppliers are not complete price takes, e.g. in the retail
sector or personal services such as hairdressing.
Monopolistic competition refers to markets in which there are a large number
of firms competing, supplying products which consumers believe are close but not
complete substitutes. Therefore, it is a market in which firms compete through
slight product differentiation, and management has discretion in pricing, trading off
price against quantity sold. The demand curve faced by each firm will be more
price elastic because of the existence of considerable competition. It is assumed
that there is relatively free entry into and exit from the industry and that entry and
exit are regulated by the level of profit earned.
Assumptions of monopolistic competition are as follows.
Relatively large numbers of firms
56
producing essentially similar (‘homogeneous’) products (goods that are meant
for similar use)
Freedom of entry and exit in the long run
Although, in the short term, firms in monopolistic competition may earn
supernormal profits (like a monopolist), in the longer term, the entry of firms and
increase in supply will erode these.

The diagram on short-run equilibrium illustrates the cost and revenue curves
for a typical firm in monopolistic competition. Assuming a goal of profit
maximization, the output q1 is sold (where MR=MC) at price p1 (note that the price
is greater than the marginal cost). By comparing the average revenue cure (AR) and
the short-run average cost curve (ATC) we can see that the firm is earning a pure
profit. This profit is AR-ATC per unit (i.e. P1-C1),which gives a total pure profit.
The profit can be expected to attract new suppliers into the market. The effect
of this is to reduce the demand for the output of the existing firms in the industry
and to increase the price sensitivity of their products. The market demand is
shared out amongst a large number of suppliers competing keenly on price.
Assuming no impediments to the competitive prices, new entry will continue until
all of the pure profit is competed away. The effect is shown in the diagram long run
equilibrium. The demand curve (AR) has shifted inwards and become more elastic
until it is tangential at the profit-maximising output to the long-run average cost
curve. At output q2 and price p2 average revenue equals average cost (AR = ATC)
and now only normal profit is earned. Only if a firm could either convince
consumers that its product was superior – and hence worth paying more for - or
obtain a cost advantage over rivals, would pure profits continue to be earned.
Monopolistic competition model suggests, therefore, that where there is a large
number of suppliers with each supplying a similar product the following will occur.
Competition will lower prices and profits as in a perfect competitive market.
However the price will remain higher and the output lower than under perfect
competition. The firm in a perfectly competitive market sets its price equal to
the marginal cost. In imperfect competition price is set above marginal cost.
57
Production occurs at less than optimum scale. In the diagram on long run
equilibrium it is clear that production, even in the long run, occurs at an
output below that at which average cost in minimized (point X)
Imperfect competition is associated with brand differentiation. This means
more expenditure on advertising and packaging which raises costs.
Firms in monopolistic competition will try to avoid competition on price, in
order to preserve their position as a price maker.

FACTOR PRICING
6.1 INTRODUCTION
Factors of production are fundamental for determining the output that is
generated in total. Factors of production and their pricing and Factor pricing under
perfect and imperfect competition

6.3.3 Demand for Factor Service
6.3.4 Supply of Factor Services
6.3.5 Factor Pricing Under Imperfect Competition
6.3.1 Differences between Factor Pricing and Product Pricing
Though, like product pricing, factor pricing is based on the forces of demand and
supply, yet there are fundamental differences between the two which make factor
pricing as a distinct theory: (i) There are differences in the nature of demand for a
product and a factor. The demand for a product is direct demand based on its
marginal utility. While the demand for a factor is derived demand – derived from the
demand for the product it helps to produce. (ii) The supply of a product depends on its
money cost, of production, while the supply of a factor depends on its opportunity cost,
the minimum earning which it can earn in the next best alternative use. (iii) The
pricing of some of the factors like labour and entrepreneur are influenced by social and
human factor, whereas product pricing is influenced little by these factors. Despite
these apparent differences, “the theory of product prices and the theory of factor prices
are parts of one whole”. As pointed out by Watson: “The costs of firms depend on factor
prices as well as on technology. The demands of consumers depend on their tastes and
on their incomes which they receive from the sale of their factors, i.e. their productive
services. Consumer demands, in turn, along with technology, determine the marginal
productivities of factors.
6.3.2 Factor Prices under Perfect Competition
The price of factor of production, like the price of a product, is determined by
demand and supply. Though the conditions of demand and supply for different factors
are different, yet certain common principles have been laid down by economists.
Assumptions
The analysis of factor pricing under perfect competition is based on the
following assumptions.
1. There is perfect competition in the product market and the factor market.
60
2. The number of buyers and sellers of factor services is large.
3. All units of a factor are homogeneous.
4. Factors of production are perfectly mobile.
5. There is perfect substitutability between factors and their units.
6. All factor-units are divisible.
7. Buyers and sellers of factor services have complete knowledge about market
conditions.
8. Buyers and sellers of factor services have complete freedom to enter and
leave the market.
9. The law of variable proportions operates.
6.3.3 Demand for Factor Service
The demand for a factor service is derived demand which is derived from the
demand for the product that it helps to produce. If the demand for the product is
high, the demand for the factor service will also be high, and vice versa. In fact, the
demand for a factor services depends not only on the demand for its products but
on its elasticity of demand. The more elastic the demand for the product is, the
greater will be the elasticity of demand of factor service used in its production. On
the contrary, the less the elasticity of demand for the product is, the lower will be
the elasticity of demand for its related factor service.

6.3.4 Supply of Factor Services
The supply of a factor service means the number of units which a resource
owner sells at a particular price. There is a direct relationship between price and
the supply of a factor service. This is in the short-run when the supply of
productive service is not perfectly elastic. More of it will be supplied at a higher
price and less at a lower price.
However, the elasticity of supply of a factor service will be determined by the
relative importance of the firm as a buyer of the productive service. Under a
perfectly competitive factor market there are many buyers of a productive service so
that a single firm purchases only a small portion of the total factor service and in
no way influences its market price. It takes the price of the factor service as given
61
and employs as many units as it needs at that price. Thus the supply of a factor
service to the firm is perfectly elastic in the long-run at the given market price. As a
result the average factor cost (AFC) and the marginal factor cost (MFC) of the
productive service to the firm are equal to the price of the factor service, AFC = MFC
= Price of the Factor Service. This is explained in Table.

Determination of Factor Price. Given the demand and supply conditions of the
factor service as enumerated above the firm will continue to employ more units of a
particular factor service so long as the additional revenue obtained from an
additional unit of the factor service (MRP) exceeds the extra cost of employing it
(MFC). It will be earning maximum profits at the point at which the marginal
revenue product equals the marginal factor cost. If the firm employs less than this,
MRP would be higher than MFC and it would be to its advantage to hire more units
of the factor service because they would add to revenue more than costs. In case
the firm decides to hire beyond the point of equality of MRP and MFC, it would be a
loser because costs would rise more than revenue. Thus in a perfectly competitive
factor market the firm will be in equilibrium when MRP MFC which implies two
conditions: first, MRP must equal MFC, and second, the MRP curve must cut the
MFC curve from above at the equilibrium point.

Figure: Units of Factor Service
The pricing of a factor service as stated above can be explained
diagrammatically. In Figure VMP = MRP is the demand curve and AFC = MFC is the
62
supply curve of the factor service. Since the price of the factor service is given and
constant at OP for the firm, the MRP curve cuts the MFC curve at E from above.
This is the equilibrium point for the firm at which it employs OQ units of the factor
service. The MRP curve also cuts the MFC curve at R. But this cannot be the
equilibrium point because MRP cuts MFC from below. It is not the point of
maximum profit for the firm because MRP is higher than MFC beyond this point R.
Thus E is the point of equilibrium in a perfectly competitive factor market when
MRP = VMP = MFC = AFC = Price.
6.3.5 Factor Pricing Under Imperfect Competition
Factor pricing under imperfect competition or monopoly is studied under three
categories: (a) when the factor market is perfectly competitive and the product
market is imperfectly competitive or monopolistic, (b) when there is monopsony in
the factor market and perfect competition in the product market, and (c) when
there is monopsony in the factor market and monopoly in the product market. We
discuss these variants of factor pricing under imperfect competition.
(A) Factor Market Perfectly Competitive and Product Market Imperfectly Competitive or
Monopolistic
In a perfectly competitive factor market, the price of the factor service is given
for the firm and does not affect the volume of its purchases. The supply curve or
the cost curve is horizontal to the X-axis (AFC = MFC). But because there is
imperfect or monopoly in the product market, the MRP curve will lie below the VMP
(value of marginal product) curve. Since we know that under imperfect competition
or monopoly in the product market marginal revenue is less than price (AR) of the
product, therefore the marginal revenue product will be less than the value of
marginal product. Symbolically, MRP<VMP since MR<P (under imperfect
competition both AR and MR curves slopes downward).

The firm will be in equilibrium where MRP equals MFC, the price of the factor
under perfect competition. This is shown in Figure-A Units of Factor Service by
point E where the firm employs OQ units is QE which is less than QA the value of
its marginal product. Thus the factor services gets less than the value of its
marginal product by EA amount. Moreover, when the firm equates MRP with MFC it
employs less units of the factor service because of imperfect competition in the
product market than what it would have had there been perfect competition. Thus
it employs OQ units of the factor, as compared with OQ1 units (where VMP = MFC)
that a competitive product seller would employ consequently. Under imperfectly
competitive product market, the demand for the factor will be less by Q1Q.
(B) Monopoly in the Factor Market and Perfect Competition in the Product Market
A monopolist firm is a single buyer of a particular factor in the market. Since
the firm is the market for the factor in this case, the supply of factor service to the
monopolist is identified to its supply to the market. Thus the supply curve to the
firm (AFC) is positively sloping from left to right upward. The firm can employ more
units of the factor service by offering a higher price per unit. The MFC curve to this
AFC curve will also be sloping upward and will be above the AFC curve throughout
its length. This is illustrated in the Table B. Columns (1) and (2) show the supply of
the factor units at various prices. Column (3) shows the total cost of employing
each unit of the factor service [column (1) X (2)]. Column (4) shows the average
factor cost which is found out by dividing column (3) by column (1). The result is
that column (4) equals column (1), i.e. AFC = Price. Column (5) shows the marginal
factor cost which is the addition made unit of the factor service. It is the difference
between successive total costs shown in column (3). Thus the table reveals that
MFC > AFC = Price.
Since we are assuming perfect competition in the product market, the value of
the marginal product will be equal to the marginal revenue product (VMP = MRP).
The firm can sell any amount without affecting the price of the product and the
value of the marginal product (VMP) therefore coincides with the marginal revenue
product (MRP), as shown in Figure-B.

(C) Monopsony in the Factor Market and Monopoly in the Product Market
When there is monopsony in the factor market and monopoly in the product
market, the MRP < VMP and the MFC > AFC. This implies that the MRP curve will
lie below the VMP curve and MFC curve will lie above the AFC curve, as shown in
Figure C. As usual, the firm is in equilibrium at point E where the MRP curve cuts
the MFC curve from above and equals it. The firm employs OQ units of the factor
service at QP price which is less than QE the marginal revenue product of the
factor.

Thus due to its monopolistic position in the factor market, the firm exploits the
factor units used to the extent of PE (QE-QP). On the other hand, due to its
monopolistic position in the product market, the MRP of the factor is less than its
VMP and the firm exploits the factor units employed further to the extent of EA
65
amount. We may conclude that in the case of monopsony in the factor market and
monopoly in the product market, the factor used in production by the firm is
doubly exploited: first, due to the excess of MRP over the price of the factor, and
second, due to the excess of the VMP over the marginal revenue product of the
factor.

FINANCE FUNCTION
7.1 INTRODUCTION
All business decisions have financial implication. A single decision may
financially affect different departments of an organisation. Financial management
may be described as making decisions on financial matters, implementing the
decisions and review of the implementation. It is the process of managing the
finance function

7.3.1 Functions of a Financial Manager (Management)
Some of the major functions of a financial manager are as follows:
1. Estimating the Amount of Capital Required
2. Determining Capital Structure
3. Choice of Sources of Funds
4. Procurement of Funds
5. Utilisation of Funds
6. Disposal of Profits or Surplus
7. Management of Cash
8. Financial Control.
Finance is the lifeblood of business concern, because it is interlinked with all
activities performed by the business concern. In a human body, if blood circulation
is not proper, body function will stop. Similarly, if the finance not being properly
arranged, the business system will stop. Arrangement of the required finance to
each department of business concern is highly a complex one and it needs careful
decision. Quantum of finance may be depending upon the nature and situation of
the business concern. But, the requirement of the finance may be broadly classified
into two parts: Long-term Financial Requirements or Fixed Capital Requirement
Financial requirement of the business differs from firm to firm and the nature of the
requirements on the basis of terms or period of financial requirement, it may be
long term and short-term financial requirements.
67
Long-term financial requirement means the finance needed to acquire land
and building for business concern, purchase of plant and machinery and other
fixed expenditure. Long- term financial requirement is also called as fixed capital
requirements. Fixed capital is the capital, which is used to purchase the fixed
assets of the firms such as land and building, furniture and fittings, plant and
machinery, etc. Hence, it is also called a capital expenditure.
Short-term Financial Requirements or Working Capital Requirement Apart
from the capital expenditure of the firms, the firms should need certain expenditure
like procurement of raw materials, payment of wages, day-to-day expenditures, etc.
This kind of expenditure is to meet with the help of short-term financial
requirements which will meet the operational expenditure of the firms. Short-term
financial requirements are popularly known as working capital.
7.3.2 Working Capital
Capital required for a business can he classified under two main categories. They are:
a. Fixed capital
Capital required for purchase of fixed assets like land, building, plant,
machinery, office equipment and furniture is called fixed capital. These assets are
purchased for constant use in production. They are not intended for re -sale. These
fixed assets are used on a permanent basis for producing goods and services.
Hence, fixed capital requirements are financed by means of share capital and long
term borrowings. The amount of fixed capital required will depend upon the size of
the organisation and the nature of business.
b. Working capital
Capital required for purchase of raw materials and for meeting the clay-to—
day expenditure on salaries, wages, rent, advertising etc is called working capital.
In simple words, working capital refers to that part of a firm’s capital which is
required for financing short-term operations or current assets such as stock,
debtors, cash etc.
Concept of working capital: There are two concepts of working capital. They are:
a. Gross working capital
In a broad sense, the working capital refers to the gross working capital. This
represents amount of funds invested in current assets, Under the gross concept,
working capital is equal to total current assets. Current assets are those assets
which can he converted into cash within an accounting year (or operating cycle) It
includes I. Cash in hand and at hank 2. Sundry debtors less provision 3. Bills
receivables 4. Closing stock 5. Short-term investments 6. [‘repaid expenses, 7.
Accrued incomes.
b. Net working capital
In a narrow sense, working capital refers to net working capital. Networking
capital is the excess of current assets over current liabilities. Current liabilities are
those claims which are expected to mature for payment with in an accounting year.
68
It includes 1 .Sundry creditors 2. Bills payable 3. Outstanding expenses 4. Bank
overdraft 5.Dividend payable, 6.Provision for taxation.
Net working capital may be positive or negative. When the current assets
exceed current liabilities, the working capital is positive. On the other hand, when
the current liabilities exceeds current assets, the working capital is negative.
Both gross working capital and net working capital concepts are important
aspects of working capital. The gross working capital is suitable to company form of
organisation where there is divorce between ownership and management and
control. But the net working capital concept may be suitable for sole proprietorship
or partnership firm. Of the two, net working capital concept is widely accepted.
7.3.3 Term Loans
An understanding of the several essential elements of a term loan is necessary
in order to appreciate fully the important and unique position that such loans have
come to occupy in the business credit market of the United States. The basic
elements that define a term loan are: (1) credit extended to a business concern; (2)
a direct relationship between borrower and lender; (3) provision at time of making
the loan that some part of the principal is repayable after the passage of one year.1
'While particular types of collateral security, repayment provisions, uses of funds by
borrowers or loan agreements may be associated with term loans, none of these are
essential characteristics
Term Loans Are a Form of Business Credit
The fact that term loans are credits extended to business concerns serves to
differentiate them from many other types of loans, also having terms of more than
one year, that are made by commercial banks, insurance companies and other
financial institutions. The salient factor is that the term lender usually appraises
the probabilities of financial success of a business enterprise in judging the
likelihood of repayment of the loan at maturity. Thus the definition of term loans
excludes consumer loans, where attention is focused on the moral and financial
worth of an individual—who is not necessarily an entrepreneur. Also excluded are
loans to individuals se-cured by mortgages on residential property. In making loans
of this type the lender customarily looks to the value of the pledged In contrast,
even where term loans to businesses are collaterally secured by real estate or other
property, the lender generally looks mainly (or exclusively) to the earning power of
the business rather than to the value of pledged property to protect himself against
loss. The collateral security given by a business concern is usually of a specialized
type that cannot be liquidated by the lender to realize any certain amount in case of
default.
7.3.4 Cash Flow Statement
Cash flow statement is a statement which shows the sources of cash inflow
and uses of cash out-flow of the business concern during a particular period of
time. It is the statement, which involves only short-term financial position of the
business concern. Cash flow statement provides a summary of operating,
69
investment and financing cash flows and reconciles them with changes in its cash
and cash equivalents such as marketable securities. Institute of Chartered
Accountants of India issued the Accounting Standard (AS-3) related to the
preparation of cash flow statement in 1998
Cash plays a very important role in the economic life of a business. A firm
needs cash to make payment to its suppliers, to incur day-to-day expenses and to
pay salaries, wages, interest and dividends etc. In fact, what blood is to a human
body , cash is to a business enterprise. Thus, it is very essential for a business to
maintain an adequate balance of cash. For example, a concern operates profitably
but it does not have sufficient cash balance to pay dividends, what message does it
convey to the shareholders and public in general. Thus, management of cash is
very essential. There should be focus on movement of cash and its equivalents.
Cash means, cash in hand and demand deposits with the bank. Cash equivalent
consists of bank overdraft, cash credit, short term deposits and marketable
securities. Cash Flow Statement deals with flow of cash which includes cash
equivalents as well as cash. This statement is an additional information to the
users of Financial Statements. The statement shows the incoming and outgoing of
cash. The statement assesses the capability of the enterprise to generate cash and
utilize it. Thus a Cash-Flow statement may be defined as a summary of receipts
and disbursements of cash for a particular period of time. It also explains reasons
for the changes in cash position of the firm. Cash flows are cash inflows and
outflows. Transactions which increase the cash position of the entity are called as
inflows of cash and those which decrease the cash position as outflows of cash.
Cash flow Statement traces the various sources which bring in cash such as cash
from operating activities, sale of current and fixed assets, issue of share capital and
debentures etc. and applications which cause outflow of cash such as loss from
operations, purchase of current and fixed assets, redemption of debentures,
preference shares and other long-term debt for cash. In short, a cash flow
statement shows the cash receipts and disbursements during a certain period.
Objectives of cash flow statement
The statement of cash flow serves a number of objectives which are as follows :
Cash flow statement aims at highlighting the cash generated from operating
activities.
Cash flow statement helps in planning the repayment of loan Schedule and
replacement of fixed assets, etc.
Cash is the centre of all financial decisions. It is used as the basis for the projection
of future investing and financing plans of the enterprise.
Cash flow statement helps to ascertain the liquid position of the firm in a better
manner . Banks and financial institutions mostly prefer cash flow statement to
analyse liquidity of the borrowing firm.
Cash flow Statement helps in efficient and effective management of cash.
The management generally looks into cash flow statements to understand the
internally generated cash which is best utilised for payment of dividends
70
7.3.5 Liquidity
Liquidity is the ability of a company to meet the short term obligations. It is
the ability of the company to convert its assets into cash. Short term, generally,
signifies obligations which mature within one accounting year. Short term also
reflects the operating cycle: buying, manufacturing, selling, and collecting. A
company that cannot pay its creditors on time and continue not to honour its
obligations to the suppliers of credit, services, and goods can be declared a sick
company or bankrupt company. Inability to meet the short term liabilities may
affect the company’s operations and in many cases it may affect its reputation too.
Lack of cash or liquid assets on hand may force a company to miss the incentives
given by the suppliers of credit, services, and goods. Loss of such incentives may
result in higher cost of goods which in turn affect the profitability of the business.
So there is always a need for the company to maintain certain degree of liquidity.
However, there is no standard norm for liquidity. It depends on the nature of the
business, scale of operations, location of the business and many other factors.
Every stakeholder has interest in the liquidity position of a company. Supplier of
goods will check the liquidity of the company before selling goods on credit.
Employees are also have interest in the liquidity to know whether the company can
meet its employees’ related obligations: salary, pension, provident fun d etc.
Shareholders are interested in understanding the liquidity due to its huge impact
on the profitability. Shareholders may not like high liquidity as profitability and
liquidity are inversely related. However, shareholders are also aware that non -
liquidity will deprive the company from getting incentives from the suppliers,
creditors, and bankers. Liquidity and Business Decisions One can understand the
liquidity position by analyzing the financial statements of a company. Following
financial items are required to understood to understand the liquidity position of a
company:
Current Assets
Current Liabilities
Liquidity position of a company can examined through financing decisions or
investment decisions. A company can finance its investment by different
combination of current and long term sources. In other words, a company can
invest the money, raised through short term source or long term sources, in the
current assets or non-current assts. Some of the relevant business strategies are as
follows:
Financing the current assets by current sources
Financing the current assets by the long term sources
Financing non-current assets by the short term sources
Financing non-current assets by long term sources One can get an idea about
the above mentioned decisions by seeing the balance sheet or determining the
working capital of a company. Liquidity and Working Capital Financial Accounting
Short Term Liquidity
71
As mentioned in the previous section, working capital helps in understanding
the liquidity position of a company. It also shows the financ ing or investment
decisions of a company. Working capital is the excess of current assets over the
current liabilities. So working capital of a company can take one of the following
directions:
Positive working capital: When current assets are more than the current
liabilities
Negative working capital: When the current liabilities are more than the
current assets
Zero working capital: when the current assets are equal to the current
liabilities
Conventionally, it is accepted that higher the positive working capital, better is
the liquidity position. The rationale of this position is that the it is easier to sell off
the current assets and make the payment towards the current liabilities.

THEORIES OF INTEREST AND PROFIT
8.1 INTRODUCTION
'Interest' is one form of payment made for using someone's money for our
purpose. It can be understood as opportunity cost of the money that someone
forego for our use. Banks charge and pay interest simply applying the above
principle. Interest rate as a concept is very important in determining many vital
factors in any economy
'Profit' is the buzz word for any business house. The extent and the dimension
of profit of a business house may determine the nature of competition in that
industry, it is the reward for the entrepreneurs to run the business

8.3.1 INTEREST
In common parlance interest is a payment made by a borrower to the lender
for the money borrowed and is expressed as a rate per cent per year.
In economics, interest has been defined in a variety of ways. Commonly,
interest is regarded as the payment for the use or service of capital. If retained by
the owner, it can be used by him for further production and the additional product
he gets through the employment of his capital includes interest. For if he had lent
his capital to someone else, he would have received interest in returns. As Carver
said “interest is the income which goes to the owner of capital”.
In Mill’s words: “Interest is the remuneration for more abstinence”. According
to the classical economists, it is only by postponing consumption that capital can
be created. Since to abstain from consumption is disagreeable and painful, the
lender is paid a reward in the form of interest. When people abstain from
consumption they save and thus interest becomes the reward for saving. Saving,
however, does not involve any sacrifice or abstinence on the part of the rich. To
avoid this fallacy, Marshall substituted the word ‘waiting’ for abstinence and
interest is then the reward for waiting to him.
73
Keynes regarded interest as a purely monetary phenomenon, payment for the
use of money. It is the reward for parting with the liquidity of money. In Keynes
words, “The possession of actual money lulls our disquietude; and the premium
which we require to make us part with money is the measure of the degree or our
disquietude”. Interest is thus a premium which is offered to wealth-holders to
induce them to part with their cash.
Gross and Pure Interest
Pure or Net Interest: It is the payment for the use of capital or money only.
This is interest in the true economic sense. It is normally the same during a period
of time even in different markets.
Reward for Risk-Taking: The lender exposes himself to risk when he lends
money. Gross interest includes the reward for risk-taking. The greater the risk
element, the higher is the rate of gross interest. Unsecured loans are more risky
than secured ones and they carry a high premium rate.
Reward for Inconvenience: When a lender loans money he foregoes its use
for the duration of the loan. His money is locked up and cannot be used for more
profitable purposes. Or, if he needs this amount for his personal use, he will have
to undergo the inconvenience of arranging it from some other source. In fixing the
rate of interest the lender includes in it the reward for such inconveniences.
Reward for Management: The lender has to incur expenditure in keeping
proper accounts of the borrowers. He buys account books and even maintains staff.
He has to remind the borrowers and sometimes has to file a suit for the recovery of
loans. The payment that the lender receives from the borrower also includes the
expenses for management.
Pure interest is what remains with the lender after deducting the reward for
risk-taking, management and inconvenience from gross interest.
8.3.2 The Classical Theory Of Interest
According to the classical theory, rate of interest is determined by the supply
and demand of capital. The supply of capital is governed by the time preference and
the demand for capital by the expected productivity of capital. Both time preference
and productivity of capital depend upon waiting or saving. The theory is, therefore,
also known as the supply and demand theory of waiting or saving.
Demand Side: The demand for capital consists of the demand for productive
and consumptive purpose. Ignoring the latter, capital is demanded by the investors
because it is productive. But the productivity of capital is subject to the law of
variable proportions. Additional units of capital are not as productive as the earlier
units. A stage comes when the employment of an additional unit of capital in the
business is jut worthwhile and no more. The demand for capital is inversely related
to the rate of interest, and the demand schedule for capital slopes downward from
left to right. There are, however, certain other factors which govern the demand for
capital, such as the growth of population, technical progress, process of
rationalization, the standard of living of the community, etc.
74
Supply Side: The supply of capital depends upon savings, rather upon the
will to save and the power to save of the community. Some people save irrespective
of the rate of interest. They would continue to save even if the rate of interest were
zero. There are others who save because the current rate of interest is just enough
to induce them to save.
Determination: Assuming the level of income to be given, the rate of interest
is determined by the interaction of the demand curve and the supply curve of
capital. This is shown in figure below. D and S curves intersect at E which is the
equilibrium point when OQ quantity of capital is demanded and supplied at OR
rate of interest. If at any time the rate of interest rises above OR to OR1 the demand
for investment funds will fall and the supply of funds will increase. Since the supply
of capital is more than the demand (R1s>R1d) the rate of interest will come down to
the equilibrium level OR. The opposite will be the case if the rate of interest falls to
OR2. The demand for capital is greater than the supply (R1d1>R2s1) and rate of
interest will rise to OR. The ultimate situation is one of equality between saving and
investment brought about by the equilibrium or the natural rate of interest. If at
any time savings are more than OQ, the rate of interest would fall below OR
because the demand for capital remains the same. (Imagine a supply curve below
the S curve in the figure, D curve being the same). At the lower rate of interest,
people will save less but the demand for the investible funds will increase which will
tend to raise the rate of interest to the equilibrium level OR.

8.3.3 Keynes Liquidity Preference Theory of Interest
Keynes defines the rate of interest as the reward of not hoarding but the
reward for parting with liquidity for the specified period. It “is not the ‘price’ which
brings into equilibrium the demand for resources to invest with the readiness to
abstain from consumption. It is the ‘price’ which equilibrates the desire to hold
wealth in the form of cash with the available quantity of cash”. In other words, the
rate of interest in the Keynesian sense is determined by the demand for and the
supply of money. This theory is, therefore, characterized as the monetary theory of
interest, as distinct from the real theory of the classical.
75
Supply of Money: Of the two determinants of the rate of interest, the supply
of money refers to the total quantity of money in the country for all purposes at any
time. Though the supply of money is a function of the rate of interest to a degree,
yet it is considered to be fixed by the monetary authorities (the supply curve of
money is taken as perfectly inelastic).
Demand for Money: For the second determinant the demand for money,
Keynes coined a new term “liquidity preference” by which his theory of interest is
commonly known. Liquidity preference is the desire to hold cash. The money is
cash “lulls our disquietude” and the rate of interest which is demanded in exchange
for it is a “measure of the degree of our disquietude”. The rate of interest, in Keynes
words, is the “premium which has to be offered to induce people to hold the wealth
in some form other than hoarded money”. The higher the liquidity preference, the
higher will be rate of interest that will have to be paid to the holders of cash to
induce them to part with their liquid assets.
According to Keynes there are three motives behind the desire of the people to
hold liquid cash: (1) the transactions motive, (2) the precautionary motive, and (3)
the speculative motive.
Transactions Motive: The transaction motive relates to “the need of cash for
the current transactions of personal and business exchanges”. It is further divided
into the income and business motives. The income motive is meant “to bridge the
interval between the receipt of income and its disbursement”, and similarly, the
business motive as “the interval between the time of incurring business costs and
that of the receipt of the sale proceeds”. If the time between the incurring of
expenditure and receipt of income is small, less cash will be held by the people for
current transactions, and vice versa.
Precautionary Motive: The Precautionary motive relates to “the desire to
provide for contingencies requiring sudden expenditures and for unforeseen
opportunities of advantageous purchases”. Both individuals and businessmen keep
cash in reserve to meet unexpected needs. Individuals hold some cash to provide
for illness, accidents, unemployment and other unforeseen contingencies. Similarly
businessmen keep cash in reserve to tide over unfavourable conditions or to gain
from unexpected deals.
Keynes holds that the transactions and precautionary motives are relatively
interest-inelastic, but are highly income-elastic. The amount of money held under
these two motives (M1) is a function (L1) of the level of income (Y) and is expressed
as M1 = L1 (Y).
Speculative Motive: Money held under the speculative motive is for “securing
profit from knowing better than the market what the future will bring forth”.
Individuals and businessmen having funds, after keeping enough for the
transactions and precautionary motives, like to gain by investing in bonds at the
opportune moments. The amount of money held under the speculative motive
depends on the rate of interest.
76
8.3.4 Profits
In ordinary sense, profit is the surplus of income over expenses of production
according to a businessman. It is the amount left with him after he has made
payments for all factor services used by him in the process of production. But he
may not have been careful in calculating all such expenses of production in the
economic sense. Therefore, economists regard businessman’s profit as gross profit
as distinct from pure or net profit because it includes the following constituents.
1.Rent on Land: The businessmen may have used his own land for erecting
the factory so that he may be saved of the botheration of paying rent to some other
landlord. This rent is included in his profit. This is implicit or imputed rent which is
not part of his profit. Had he hired land from some other person, he would have
paid its rent. In calculating net profit, implicit rent should be deducted from gross
profit.
2. Interest on Capital: Similarly, he may have used his own capital in his
business in order to avoid the inconvenience of borrowing from some other person.
The implicit interest is again included in his gross profit. If he had borrowed the
same amount of capital for investment in his business, he would have paid interest
on it. This interest should, therefore, be subtracted from his gross profit to arrive at
net profit.
3. Wages of Management: The businessman may have been busy in
organizing, coordinating and managing the entire business himself. Btu he may
have been contented with income received after meeting all expenses of production.
If he had not performed the work of management himself he would have employed a
manager to whom he would have paid wages. This his gross profit includes implicit
wages which are required to be deducted for calculating net profit. In all joint stock
companies, profits are received by shareholders, the managers and managing
directors are all salaried persons whose salaries are included in the expenses of the
firms.
4. Depreciation Charges: During the process of production machinery and
plants depreciate and become obsolete. Expenses incurred on their repairs and
replacements are a part of the cost of production.
5. Insurance Charges
6. Net Profit
a) Reward for Uncertainty Bearing.
b) Reward for Coordination.
c) Rent of Ability.
d) Reward of Innovation.
e) Monopoly Gains.
f) Windfalls.
77
The Dynamic Theory
Prof. J.B. Clark propounded his dynamic theory of profit in 1900. To him,
profit is the difference between the price and the cost of production of the
commodity. But profit is the result of dynamic change. In a dynamic state, “five
generic changes are going on, every one of which reacts on the structure of society”.
They are:
1. Population is increasing.
2. Capital is increasing.
3. Methods of production are improving.
4. The forms of industrial establishment are changing, the less efficient
shops, etc., are passing from the field, and the most efficient are surviving.
5. The wants of consumers are multiplying.
In the static state, competition tends to eliminate these five kinds of changes
so that each factor receives what it produces. The selling price and the cost of
production are equal and there are no profits. What entrepreneurs receive are
simply wages of management.
Profits are the result exclusively of five dynamic changes, i.e., changes in
population, capital, techniques of production, forms of business organization and in
the wants of people.
The Innovation Theory
Prof. Schumpeter attributes profits to dynamic changes resulting from an
innovation.
Schumpeter assigns the role of an innovator not to the capitalist but to the
entrepreneur. The entrepreneur is not a man of ordinary managerial ability, but
one who introduces something entirely new. He does not provide funds but directs
their use. To perform his economic function, he requires two things: first, the
existence of technical knowledge in order to produce new products: and second, the
power of disposal over the factors of production in the form of credit. He gets credit
from the banks and uses his ability to un tap the existing technical knowledge. This
brings about an innovation which disturbs the circular-flow of production in the
economy and leads to the emergence of profits. Thus the role of the entrepreneur is
quite distinct from that of the capitalist.
Profits therefore, accrue to the entrepreneur as a reward for innovating and
not as a reward for risk-taking. According to Schumpeter, an innovation may
consist of:
1. the introduction of a new product;
2. the introduction of a new method of production;
3. the opening up of new market;
4. the discovery of a new source of raw materials; and
5. the reorganization of the industry.
78
When any one of these innovation is introduced by an entrepreneur, it tends to
reduce the cost of production of the commodity below its selling price. Profits
emerge.
The Risk Theory
The risk theory of profit is associated with F.B. Hawley who regards risk-taking
as the main function of the entrepreneur. Profit is the residual income which the
entrepreneur receives because he assumes risks. The entrepreneur exposes his
business to risk, and receives in turn a reward in the form of profit because the
task of risk-taking is irksome. Profit is ‘an excess of payment above the actuarial
value of the risk’. No entrepreneur will be willing to undertake risks if he gets only
the normal return. Therefore, the reward for risk-taking must be higher than the
actual value of the risk.
According to Hawley, the entrepreneur can avoid certain risks for a fixed
payment to the insurance company. But he cannot get rid of all risks by means of
insurance, for if he is able to do so, he would cease to be an entrepreneur and
would earn only wages of management and no profit.
But all persons are incapable of undertaking risks, so risks act as a deterrent
to the supply of entrepreneurs. Those who remain in business are able to earn an
excess of payment above the actuarial value of the risk.
The Uncertainty-Bearing Theory
Prof. Frank H. Knight regards profit as the reward of bearing non-insurable
risks and uncertainties. He distinguishes between insurable and non-insurable
risks. Certain risks are measurable in as much as the probability of their
occurrence can be statistically calculated. The risk of fire, theft of merchandise and
of death by accident are insurable. There are certain unique risks which are
incalculable. The probability of their occurrence cannot be statistically computed
because of the presence of uncertainty in them.
Profit is thus the difference between ex ante and ex post returns. In a
competitive economy if entrepreneurs compete cautiously and do not raise the
prices of factor services to the value of their marginal product, they will earn
positive profit.
Uncertainty-bearing is the most important function in a dynamic state. It is
the entrepreneur who either delegates this function among different personnel or
assumes them himself. The expectation of profit is, in a way, the supply price of
entrepreneurial uncertainty-bearing. In a competitive economy where there is no
risk, every entrepreneur will have a minimum supply price. If his reward fall below
it, entrepreneurial services will not be supplied. But the presence of uncertainty
tends to raise the minimum supply price which is actually a ‘risk premium’ which
the entrepreneur expects to be paid. This is profit.
“Only unpredictable changes give rise to profit. Changes in population and
capital being predictable do not occasion imperfect competition or profit. Thus
79
profit is due to non-insurable risks and uncertainties generated by dynamic
change.
8.3.5 Functions of an Entrepreneur
i) Identifying Entrepreneurial Opportunity: There are many opportunities in
the world of business. These are based on human needs like food, fashion,
education, etc., which are constantly changing. These opportunities are not realised
by common man, but an entrepreneur senses the opportunities faster than others
do. An entrepreneur therefore, has to be creative and innovative.
ii) Turning Ideas into Action: An entrepreneur should be capable of turning
his ideas into reality. He collects information regarding the ideas, products,
practices to suit the demand in the market. Further steps are taken to achieve the
goals in the light of the information collected.
iii) Feasibility Study: The entrepreneur conducts studies to assess the
market feasibility of the proposed product or services. He anticipates problems and
assesses quantity, quality, cost and sources of inputs required to run the enterprise
by preparing a ‘project report’.
iv) Resourcing: The entrepreneur needs various resources in terms of money,
machine, material, and men to running the enterprise successfully. An essential
function of an entrepreneur is to ensure the availability of all these resources.
v) Setting up of the Enterprise: For setting up an enterprise the
entrepreneur may need to fulfil some legal formalities. He also tries to find out a
suitable location, design the premises, install machinery and do many other things.
vi) Managing the Enterprise: He has to manage men, material, finance and
organise production of goods and services. He has to market each product and
service, after ensuring appropriate returns (profits) of the investment. Only a
properly managed organisation yields desired results.
vii) Growth and Development: Once the enterprise achieves its desired
results, the entrepreneur has to explore another higher goal for its proper growth
and development. The entrepreneur is not satisfied only with achieving a set goal
but constantly strives for achieving excellence.

8.6 SUMMARY
Rate of interest in the Keynesian sense is ‘price’ which equilibrates the desire
to hold wealth in the form of cash with the available quantity of cash. For Keynes
80
there are three motives that drive people to hold liquid cash. 1. Transaction motive
2. Precautionary motive 3. Speculative motive. Profit can accrue in the following
forms; rent, interest on Capital, wages, Depreciation. Profit is the dynamic changes
resulting from an innovation of many types. For Professor F.B. Hawley, profit is an
excess of payment above the actuarial value of the risk. But for professor Frank H.
Knight profit is the reward of bearing non-insurable risks and uncertainties.

MONEY
9.1 INTRODUCTION
Money as a medium of exchange completes transaction of goods and services
among various parties. After introduction of money the 'barter' system hardly
exists. It paved way for various other forms of money
9.2 OBJECTIVES
To know history of various forms of money from the genesis till date
To understand various functions of Money
To know the relationship between money supply and GDP
9.3 CONTENTS
9.3.1 The Origin of money
9.3.2 Money supply
9.3.3 Demand for money
9.3.4 Relationship between money supply and GDP
9.3.1 Introduction – The Origins
The origins of money are lost in antiquity; most primitive tribes known today
make some use of it. The ability of money to free people from the cumbersome
necessity of barter must have led to its early use as soon as some generally
acceptable commodity appeared.
Metallic money
All sorts of commodities have been used as money at one time or another, but
gold and silver proved to have great advantages. They were precious because their
supply was relatively limited, and they were in constant demand by the rich for
ornament and decoration. Thus they tended to have a high and stable price.
Before the invention of coins it was necessary to carry the metals in bulk.
For the reasons of abuse of metallic money other forms of money came into
existence.
Paper Money
When it first came into being, paper money was a promise to pay on demand
so much gold, the promise being made first by goldsmiths and later by banks.
Banks, too, became known for their vaults (safes) where the precious gold was
stored and protected. As long as the institutions were known to be reliable their
pieces of paper would be a “as good as gold”. Such paper money was backed by
precious metal and was convertible on demand into this metal.
The history of nineteenth and early twentieth century banking on both sides of
the Atlantic is full of examples of banks ruined by “panics,” sudden runs on their gold
reserves. Central banks were a natural outcome of this sort of banking system.
Fiat Currencies
As time went on, note issue by private banks became less common and central
banks took control of the currency. Central banks in turn became governmental
institutions. In time only central banks were permitted to issue notes. Originally
the central banks issued currency that was fully convertible into gold.
82
During the period between World War I, II almost all the countries of the world
abandoned the gold standard; their currencies were no longer convertible into gold.
Money that is not convertible by law into anything valuable depends upon its
acceptability for its value. Money that is declared by government order or fiat, to be
legal tender for settlement of all debts is called a fiat money. Today almost all
currency is fiat money.
Functions of Money: Money is what money does. Anything that performs
the functions of money is money. There are three function of money.
Medium of exchange: It is the first and foremost function. It is usable in
buying and selling goods and services. As a medium of exchange, money allows
society to escape the complications of barter and thereby to reap the benefits of
geographic and human specialisation
Standard of value: Society finds it convenient to use the monetary unit as a
yardstick for measuring the relative worth of heterogeneous goods and resources.
Just as we measure distance in miles or kilometres, we gauge the value of goods
and services in terms Rupees. This has distinct advantages. With a money system,
we need not state the price of each product in terms of all other products for which
it might possibly be exchanged; we need not state the price of cows in terms of
grains, cloths, barrels of oil etc., This use of money as a common denominator
means that the price of each product need be stated only in monetary unit. Money
is also used as standard of value for transactions involving future payments. Debt
obligations of all kinds are measured in terms of money.
Store of Value: Because money is the most liquid of all assets, it is a very
convenient form in which to store wealth. Most methods of holding money do not
yield monetary returns such as one gets by storing wealth in the form of real assets
(property) or paper assets (stocks, bonds, and so forth). However, money does have
the advantage of being immediately usable by a firm or a household in meeting any
and all financial obligations.
There is distinction between money and income. What we earn is not money.
Money is used only to pay the income. We need money because it serves as a
common item in which the prices of all goods and services can be set.
9.3.2 Money Supply
It is currency and chequeable deposits with the banks. This is the narrow
definition of money and denoted by M1 in our monetary statistics. There is also a
broad definition of money. Broad money includes, in addition to M1, fixed or time
deposits with banks, which are not usually available for spending until the end of
the term, but, nevertheless, can be converted into saving or chequeable deposits in
no time, with some loss of interest. Broad money, there more is defined as
currency + all bank deposits and is denoted by M3 in our monetary statistics.
When we talk of money supply, we usually refer to M3.
9.3.3 Demand for Money
An individual’s wealth can be held, broadly, in two forms
(a) Interest bearing assets
83
(b) Non-interest bearing assets or, money
The interest bearing assets are bonds. So when we are asking why do we
demand money, we are, essentially, asking as to why would anyone like to demand
money which either yields no interest (Currency) or which yields very low interest
(chequeable deposits) when this money can be held as interest bearing bonds?
When we are talking about demand for money we are referring to real money
demand. In other words we are saying that if the price level doubled over night,
then the amount of money people would want to hold would also double. Thus the
demand for money is proportional to the level of prices. Real money demand, then,
is quantity of money demand divided by the price level.
First we demand money to buy goods and services. This is called the
transaction demand for money. This is the primary motive. The demand for money
to transact in goods and services is the positive function of income (GDP). Higher
the income greater will be the need to buy goods and services and hither will be the
transaction demand for money. But is also a negative function of interest rates. If
interest rate rises, we are foregoing a higher return by holding money. So the
temptation to hold less at any point of time. For example, instead of drawing
money for the whole month I may draw money weekly and let the balance money
earn interest in the meantime.
The second reason for holding money is precautionary. Individuals and firms
hold money with a precautionary motive for unforeseen contingencies. It will also
depend on how much interest we are foregoing on this money held. Thus
precautionary demand for money is also a positive function of income and a
negative function of interest rates.
The speculative demand for money, thus, arise because people think that by
holding a certain stock of money, they can make capital gains or avoid capital
losses. There is an inverse relationship between bond prices and interest rate.
Speculative demand for money is also a positive function of income to the extent
that the more income you have the more you can afford to speculate. We can
conclude then, the demand for money is an increasing function of income and
decreasing function of interest rate.
9.3.4 Relationship between Money Supply and GDP
GDP is the total production goods and services in the economy and money
refers to a stock of liquid assets, which can be exchanged for goods and services. A
given stock of money flows through the economy a number of times (called velocity
of circulation) each time resulting in a new transaction, and the value of the GDP is
nothing but the sum total of all these transactions over a period of time. GDP
therefore depends on the stock of money multiplied by the speed with which the
money changes hands. If the number of times money changes hands, or the
velocity of circulation, is assumed to be stable, then there is a close relationship
between the stock of money and GDP. As the stock of money increases, more goods
and services will be exchanged and the GDP will rise. However, there is a catch. If
the economy is already operating close to full capacity, and the money supply
continues to grow they have a situation where the money supply is rising but the
84
supply of goods and services, which can be exchanged for this money, is not rising
correspondingly. There is more money chasing few goods and services. As a result
prices will increase more than the increase in real output and the policy maker may
have to carefully, weigh the trade-offs, considering the fact that price stability is one
of the paramount objectives of macroeconomic policy
On the other hand, if the GDP is below the capacity of the economy to
produce, an increase in the money stock can plan a simulative role in the economy
by increasing real output with little rise in prices.

COMPONENTS OF ECONOMY
10.1 INTRODUCTION
The functioning and strength of any economy is explained by the strengths of
the various sectors of that economy. The nature of growth of any economy is
explained by how effectively the sectors interact with each other
10.2 OBJECTIVES
To understand the sectoral contribution of various sectors for the
development of a country
To understand the nature and problems of urbanisation and its impact on
economy
10.3 CONTENT
10.3.1 Sectors
10.3.2 Trends in change in growth of economic development
10.3.3 Urbanisation
10.3.1 Sectors
Primary Sector
When the economic activity depends mainly on exploitation of natural
resources then that activity comes under the primary sector. Agriculture and
agriculture related activities are the primary sectors of economy.
Secondary Sector
When the main activity involves manufacturing then it is the secondary sector.
All industrial production where physical goods are produced come under the
secondary sector.
Tertiary Sector
When the activity involves providing intangible goods like services then this is
part of the tertiary sector. Financial services, management consultancy, telephony
and IT are good examples of service sector.
10.3.2 Trends in Change in the growth of Sectoral contribution to Economic Development
Structural transformations in modern economic growth include the shift away
from agriculture to non-agricultural activities (Primary to secondary) and from
industry to services sectors (Secondary to Tertiary). A change in the scale of
productive units, and a related shift from personal enterprises to impersonal
organisation of economic firms, with a corresponding change in the occupational
status of labour experienced.
The share of the agricultural sector in total product declined in all developed
countries except Australia.

On the other hand share of the industrial sector rose to more than 50 per cent
by the end of the long period for the following countries

MANUFACTURING

FRANCE 52

JAPAN 49
GERMANY 52

USSR 58
NORWAY 53
The rapidity of structural transformation in modern economic growth can also
be illustrated by the changes in the distribution of labour force among the three
major sectors. For example, By end of the long periods of growth, the share of
labour force attached to the agricultural sector was 5 per cent in Great Britain -
lowest among the world countries.
Consequently the share of labour force attached to the industrial sector ranged
between 50 per cent among the developed countries.
The intersectoral shifts were accompanied by growth in the scale of firms and
changes in the type of organisation within sectors such as manufacturing or trade,
from small incorporated forms to the large corporate units with the rapid shifts in
industrial structure and rapid change in technology.
There were also rapid shifts in allocation of product among types and sizes of
producing firms and consequently in the allocation of labour force. There was high
inter-industry, inter-status, and inter-occupational mobility of the labour force
among employees from blue-to white-collar jobs, from less to more skilled
occupations and from small to large enterprises.
10.3.3 Urbanisation
Modern economic growth has been characterised by the movement of an
increasing proportion of the population in developed countries from rural areas to
urban areas is known as urbanisation. This urbanisation is largely a product of
industrialisation.
87
1. Urbanisation affected the level and structure of consumer expenditure in
developed countries in three ways
2. Urbanisation lead to an increasing division of labour, growing specialisation,
and the shift of many activities from non-market oriented pursuits within the
family or the village to specialised market-oriented firms
3. Urbanisation made the satisfaction of an increasing number of wants more
costly. Urban life became costlier because of congestion and overcrowding.
This created difficulties of housing, sanitation, water, intra-city and city
transportation and similar basic amenities in the cities.
The demonstration effect of the city life lead to imitation of consumption
patterns by the large immigrants, which lead to increased consumer expenditure.
Problems in Urban areas/Cities: parasitic Components
Cities have always placed demands on their sites and their hinterlands. In
order to extend their usable territory, urban developers often reshaped natural
landscapes, levelling hills, filling valleys and wetlands, and creating huge areas of
made land.
On this new land, they constructed a built environment of paved streets,
malls, houses, factories, office buildings, and churches. In the process they altered
urban biological ecosystems for their own purposes, killing off animal populations,
eliminating native species of flora and fauna, and introducing new and foreign
species.
Thus urbanites, constructed a built environment that replaced the natural
environment and created a local micro-climate, with different temperature gradients
and rainfall and wind patterns than those of the surrounding countryside.
City populations require food, water, fuel, and construction materials, while
urban industries need natural materials for production purposes. In order to fulfill
these needs, urbanites increasingly had to reach far beyond their boundaries.
In the twentieth century, as urban population increased, the demand for food
drove the rise of large factory farms. The subject of the flow of food and other such
commodities into 19th century cities and its subsequent marketing, however, still has
to find its historian. Cities also require fresh water supplies in order to exist --
engineers, acting at the behest of urban elites and politicians, built waterworks, thrust
water intake pipes ever further into neighbouring lakes, dug wells deeper and deeper
into the earth looking for groundwater, and dammed and diverted rivers and streams
to obtain water supplies for domestic and industrial uses and for fire-fighting.
In the process of obtaining water from distant locales, cities often transformed
them, making deserts where there had been fertile agricultural areas. The
acquisition of protected water shed areas and the building of reservoirs often
resulted in the flooding of many towns and farms.
City entrepreneurs and industrialists were actively involved in the
commodification of natural systems, putting them to use for purposes of urban
consumption. The exploitation of water power from rivers and streams for instance,
88
provided power for manufacturing cities, also sharply altered river dynamics,
destroying fish populations and depriving downstream users of adequate and
unpolluted supplies.
For materials to build and to heat the city, loggers stripped millions of acres of
forests, quarrymen tore granite and other stone from the earth, and miners dug
coal to provide fuel for commercial, industrial and domestic uses.
Urbanites had to seek locations to dispose of the wastes produced. by their
construction, manufacturing and consumption. They were, seeking an "ultimate
sink" for the wastes, but often ended up polluting downstream locales. Initially,
they placed wastes on sites within the city, polluting the air, land, and water with
industrial and domestic effluents and modifying and even destroying natural
biological systems. In the post-Civil War period, as cities grew larger, they disposed
of their wastes by transporting them to more distant locations.
Cities constructed sewerage systems for domestic wastes. They usually
discharged the sewage into neighbouring waterways, often polluting the water
supply of downstream cities. In order to avoid epidemics of waterborne disease
such as typhoid and cholera, downstream cities sought new sources of supply or
used technological fixes, such as water filtration or chlorination, but the choices
were not simple. Industrial wastes also added to stream and lake pollution, and
urban rivers often became little more than open sewers.
The suburban out-migration, which had begun with commuter trains and
streetcars accelerated because of the availability and convenience of the
automobile, now increased to a torrent, putting major strains on the formerly rural
and undeveloped metropolitan fringes. To a great extent, suburban layouts, ignored
environmental considerations, making little provision for open space, producing
endless rows of resource-consuming and pesticide-and fertilizer-dependent lawns,
contaminating groundwater through leaking septic tanks, and absorbing excessive
amounts of fresh water and energy.
The growth of the edge or outer city since the 1970s, reflected a continued
preference on the part of Americans for space-intensive single-family houses
surrounded by lawns, for private automobiles over public transit, and for Greenfield
development. Without greater land use planning and environmental protection,
urban areas will, as it has in the past, continue to damage and to stress the natural
environment.

environment. The issues are solid waste generation, Air Pollution, Water pollution
and shrinking sources of potable water. Transport and traffic management is a day

NATIONAL INCOME
11.1 INTRODUCTION
As a concept it is different from Private income. Private budget (income
expenditure statement) adjusts expenditure according to income. Whereas public
budget decides the expenditure first and augments income for the expenditure.
National income is one of the indicator of Economic Growth of an Economy
11.2 OBJECTIVES
To introduce different methods of estimation of National Income
To know the concept of circular flow of income.
To know the relationship between money supply and GDP
11.3 CONTENTS
11.3.1 National Income
11.3.2 Gross National Product
11.3.3 Gross Domestic Product
11.3.4 Economic Units and Circular Flow of Income
11.3.5 National Income Measurement
11.3.1 NATIONAL INCOME
National Income – income of the nation during a period of time – provides a
comprehensive measure of the economic activities of a nation. Its annual
magnitude divided by the nation’s population, called the per capita income, is
used as a measure of the standard of living of the people in the nation, and the
distinction between rich, middle income and poor countries is based on the
magnitude of the per capita income.
The growth rate of an economy is also measured by the rate at which its real
national income is growing. Knowledge of the national income and its movements
over time is of significance to a business organization also, as this provides a
measure of the nation’s ability to buy goods and services, and, thus, business sales
are dependent on its magnitude.
Income Concepts
There are several versions of national income, though, strictly speaking, only
one of them is referred to as the national income. These include:
Gross National Product (GNP)
Net National Product (NNP)
These measures define both at the market price as well as at the factor cost.
Thus, we have the GNP at market price (GNPM), NNP at the market price (NNPM),
NNP at the factor cost (NNPF).
91
11.3.2 Gross National Product
The GNP at market price stands for the monetary value of all goods and
services that are
(a) Currently produced.
(b) Sold through the official market.
(c) Not resold or used in further production during the measurement period.
(d) Produced by nationally owned resources (factors of production).
(e) Valued at market prices
A brief rationale and explanation of these factors follows
GNP is expressed in terms of money (rupees in India) because the goods and
services are non-additive in physical quantities due to differences in the units of
measurements (tonnes of wheat, metres of cloth, number of cars, number of
haircuts etc) and the per unit values (one car is not equal to one haircut or even
one scooter). It is said that ‘you cannot add apples and oranges’. By using the
prices, the GNP is constructed. Quantities of various goods are multiplied by their
respective prices, and then the various money magnitudes are added to give GNP.
Income is a flow concept and so the GNP includes only those items that are
produced during the period of time for which the GNP stands. Thus, the GNP in
1991 includes the production of all goods and services between January 1, 1991
through December 31, 1991 only. The changes in inventories during the pe riod are
treated as positive or negative purchases by the producer for the purpose of
reconciling the production measure with the end-use expenditure measure.
The GNP accounts only for goods that are traded through the official market.
This is a limitation of the measure but it is resorted to internationally owing to the
difficulties in measuring non-marketed or not officially marketed production. Thus,
it ignores the ‘do it yourself’ activities (which are not paid for) as well as the
un/under reported productions. For example, the household work, including
babysitting, white washing of own house, and tutoring of own children and other do
it yourself activities are excluded, while payments to maid-servants, washermen,
paid babysitters, private tuitions and so on are included in the GNP. Also, activities
like painting, drawing, photography, etc, which are carried out for self-consumption
(or even for sale but not in the current year), are left out of the GNP. Similarly,
unreported productions (though a part of market transactions but not a part of
official transactions) triggered by the desire to avoid excise duties or for other
reasons, are not included in the GNP. These give rise to what is called as the black
(parallel) economy.
Raw materials and intermediate goods (i.e., goods resold or used for further
production during the measurement period) are not included in the GNP, so as to
avoid double counting of production. Thus, wheat used in making bread, leather
used in making shoes and tyres used in cars are excluded because these are
contained in the values of bread, shoes and cars, respectively.
92
The GNP belongs to the nation, and thus, it must be produced by its owned
factors of production only. Since some factors of production like labour,
entrepreneur, and capital are globally mobile and we do have multinationals
operating in many countries, a part of this GNP is produced abroad and a part of
foreign GNP is produced under a nation’s territory. Thus, if an Indian resident
professor takes up a four-month’s Visiting Professorship in a University in the
United States, his income in there will be a part of India’s GNP and similarly the
profit that a foreign owned firm (say Citibank) makes in India is not a part of India’s
GNP. Thus, for GNP, the location of production is immaterial.
11.3.3 Gross Domestic Product
The GDP refers to the value of the goods and services produced within the
nation’s geographical territory, irrespective of the ownership of the resources.
GDPF = GNPF – NIA
From the point of the employment generation at home, GDP is more relevant
than GNP, and hence, the former often receives greater attention than the latter.
Corresponding to GNP and GDP, there are NNP and NDP. The difference
between the gross and the net is the capital consumption, called depreciation (D).
Thus,
NNPF = GNPF – D
NDPF = GDPF – D
It is the NNPF which is referred to as the national income. This is because
depreciation is really the consumed part of the fixed capital in the production
process and it is difficult to measure it accurately (what we have is the accounting
and not the economic depreciation).
11.3.4 Economic Units and Circular flow of Income
On the basis of the economic units, the nation could be studied through five
sectors: (a) households, (b) firms, (c) financial institutions (capital market), (d) the
government and (e) the rest of the world. These five sectors interact, produce and
circulate the income.
All the factors of production are assumed to be owned by households.
Households supply these factors to firms (governmental, private and joint), who
produce all the GNP. The firms pay factors’ rewards (rent, wage, interest and profit)
to households, corporate tax to the government and for imports to the rest of the
world, and maintain the balance as savings with financial institutions. The firms, in
turn, receive payments for supplying consumption goods to households and to the
government.
93
Circular Flow of Income
They also receive subsidies from the government for their exports to rest of the
world, and raise funds for the investments from financial institutions. The
government receives corporate tax from firms and personal tax from households
and advances subsidies to firms and transfer payments to households, besides
paying firms for their expenditure on goods and services. Its savings (lack of
savings) go to (come from) financial institutions. Financial institutions receive
savings from all the three sectors (households, firms and government) and pay for
all the investment goods to firms. Households receive payments for all owned

factors of production from firms and transfer payments from the government. It
pays firms for consumption goods, personal tax to the government and puts its
savings in financial institutions. This process continues period after period and this
is how income is produced and circulated among the various sectors of the
economy.
The circular flow of income shows leakages (withdrawals) from the national
income, which does not form a part of the expenditure on national product. These
are savings (S), taxes (T), and imports (M). Also, it indicates injections (additions)
into expenditure on national product, which do not come from national income.
These are investment (I), government expenditure (G) and exports (X). These
injections and leakages are related. Saving finances investment, partly or fully, as
do taxes finance government expenditure, Also, some of the expenditure on imports
provides foreigners with the means to purchase our exports.
Although the leakages may eventually finance the injections, they do not cause
them. There is no reason for S = I, T = G, and M = X, but the total planned leakages
must equal the total planned injections for the equilibrium to hold:
S + T + M = I + G + X
11.3.5 National Income Measurement
National income could be measured in three different ways:
Production or value added approach
Income approach
Expenditure approach
And if done correctly, the following equation must hold:
Production = Income = Expenditure
This is because the three approaches are circular in nature. It begins at
production, through recruitments of factors of production, generating and going as
incomes to factors of production, who expend it on production. A brief discussion of
these approaches follows.
Production Approach
Under this approach, the GDP at the factor cost, is measured as the sum of
the values of the flows of value added from various production centres or of the
production of final goods and services. Thus, the GDP at the factor cost is given by
GDPF = P1Q1 + P2Q2 + ……… + PnQn

Incidentally, note that equation assumes that all productions can be valued in
money terms.
The production sectors are conveniently classified into (a) primary, (b)
secondary and (c) tertiary. The primary sector includes agricul ture, forestry and
fishing, and mining and quarrying. The secondary sector consists of
manufacturing, electricity, gas and water supply, and construction. The tertiary
sector consists of all items under services. The contribution of each of these sectors
and their sub-sectors to the GDP at the factor cost (at current prices) during 1950-
51, 1980-81, 1990-991 and 2000-01 is reported in Table.
A distinction is also made between the agriculture, industry and services
sectors. The first sector includes items 1 and 2 of the table, the second, items 3, 4,
5 and 6 and items 7 through 12 go in the third sector.

A careful examination of the data in Table would reveal that in the last
50 years, the share of both the secondary and tertiary sectors in GDP has increased
substantially at the cost of that of the primary sector. Further, the role of the
tertiary sector has grown at the fastest rate. This is a sign of prosperity, provided of
course, the requirements for wage-goods are met reasonably well.
Income Approach
Under the cost or income approach, the national income equals the sum of the
costs of production of goods and services, which equals the earnings that
households receive for their factors of production. These include the wages and
96
salaries received for the supply of labour (W); rents for land, buildings, equipments,
and the like (R); interest for borrowed capital (I); and profit for entrepreneurship (P).
Thus, the NDP at the factor cost is given by
NDPF = W + R + I + P
Transfer payments/receipts, such as unemployment benefits and pensions are
not included in income. Since there are self-employed people in all countries, and
they rarely classify their incomes into the above four components, the functionally
distributed national income data contains a mixed income category. Further, a
significant proportion of the Indian people are self-employed and accordingly, the
mixed income category is a dominant component here. The Indian data on income
by factors’ share (functional distribution of income) for the selected few years are
given in table. Some columns in this table are blank as comparable data is not
available. The data reveals that labour commands the maximum share in NDP
(above 40 per cent) and that its share has increased over time. The labour share is
over whelming in all countries.

Expenditure Approach
Under this method, national income is measured as the sum of all final
expenditure. Final expenditure consists of expenditure on private consumption (C),
gross investment – both private and public (I), expenditure on government (federal,
state and local) consumption (G), foreigners’ expenditure on our exports of goods
and services (X), net of our expenditure on imports of goods and services from
abroad (M). Therefore, GDP at the market price could be measured as
GDPM = C + I + G + X – M
It must be noted that what is not consumed is saving. Further, while saving
equals investment in the world as a whole, the same is not necessarily true for a
country. This is so because some countries save more and some less than they
need to invest. The balance between the supply of savings and demand for
97
investments is met by financial flows between economies, the net of which is given
by the difference between imports and exports of goods and services. Thus, saving =
income – private consumption – government consumption = investments + exports –
income.

LESSON - 12
INFLATION AND DEFLATION
12.1 INTRODUCTION
Inflation is an everyday phenomenon impacting everyone in the economy. This
lesson details on what is the implications of it in every sector of the economy
Deflation is a phenomenon not very common to every country. It spread worse
impact than inflation in an economy if experienced.
12.2 OBJECTIVES
To familiarise various types of inflation
To explain various causes of inflation
To understand various measures to control inflation
To understand the impact of deflation
To study various policy options to combat deflation
12.3 CONTENT
12.3.1 Inflation
12.3.2 Deflation
12.3.1 Inflation
Inflation refers to a continuous rise in general price level. In India, we
estimate inflation based on the movement in wholesale price index (WPI) which is
reported every week with a two week lag. Consumer price index (CPI) is used to
arrive at cost of living changes and for the calculation of dearness allowance or cost
of living allowance. In many other countries inflation is derived from movements in
Consumer price Index (CPI)
Causes of Inflation: It can be caused by
1. Demand factors referred to as “Demand Pull” inflation can be caused by an
increase in any of the components of aggregate demand i.e., consumer
demand (C), Investment Demand (I) Government Demand (G) or, net
foreigner’s demand or some combination of the above. It is however increase
in Government demand which is the primary cause of demand pull inflation.
When the demand increases the extent of price increase depends on the
supply situation. At one extreme, let us assume that there is massive excess
capacity all around the economy and the suppliers in the economy can meet
the excess demand for goods and services without resorting to increase in
prices, then we may not see any rise in prices consequent to an increase in
demand. At the other extreme, let us assume that the economy is operating
at its full capacity and there is no scope for increasing production. In that
case, the entire increase in demand will be dissipated by way of a rise in
prices. In real life, however, we neither encounter economy wide massive
excess capacity not do we come across a situation where output cannot be
increased at all. In real life, as demand increases, price and output both
99
increase; when the economy is closer to capacity output, price ruse is steeper
and, vice versa, when there is some excess capacity in the economy.
2. Cost-push is driven by an increase in costs, independently of demand. The
Logic underlying this phenomenon is as follows. Conceptually, the
contribution that a factor of production, say labour, markets to the revenue of
a firm is the additional output that the firm gets by employing that labour
times the price of the output. The wage that they labour gets, therefore, is
supposed to reflect this. Now if, because of union pressures, wages are
pushed up without any increase in the worker’s contribution to the output,
per unit cost of production goes up at each level of output. If firms fact a rise
in costs, they will respond partly by raising prises and passing the cost on to
their consumers and partly by cutting back on production. Note that unlike
demand-pull inflation where both prices and output go up, cost-push inflation
results in a rise in prices and fall in output. We have taken the example of
labour costs here, but costs could also go up because of an increase in
material costs, import costs, due to increase in oil prices, strong bargaining
power of producers etc. in short any increase in costs or money gain greater
than productivity will result in increase in process.
Inflation can also be expectation driven. If people expect inflation to be say 5%
then based on this expectation, people will revise prices and actually take the
inflation to 5%. Expectations are formed based on post inflation rates. Policy
change, under the circumstances, lies in finding ways to douse the expectations.
Policy credibility is key to this. Otherwise, expected inflation may drive actual
inflation.
Kinds of inflation
An examination of the time series data across countries would suggest that all
countries have experienced some, though varying degrees of inflation over time. By
the degree of inflation and the trend in the inflation rate, five kinds of inflation are
distinguished.
(a) Hyperinflation/Runaway inflation
(b)High inflation
(c)Galloping inflation
(d)Low inflation
(e)Crawling inflation
Hyperinflation: Phenomenon where the rate of inflation is around 1000
percent per year (=22 percent per month, compounded) it has happened in a few
countries in the past monthly) and more. This appears to be too high an inflation
rate to prevail anywhere but it has happened in a few countries in past
Country Year of start Rate of inflation
Germany January 1922 322 percent per month
100
Hungary August 1945 19800 percent per month
Brazil 1980 – 1990s 1009-2938 percent per year
High Inflation: Inflation at the high two digit rate to the top of the three digit
rate per year. Such inflation was witnessed in the Russian federation and in Nigeria
during 1990s
Galloping inflation: is the inflation where the inflation and high inflation
countries, and would surely be found in some countries at least for few years. Most
countries in the world experienced fairly high inflation during 1974 through 1982.
Low inflation: Refers to the inflation whose rate falls within one digit to the
low two digits per year. This is the most common kind of inflation and it has been
experienced by most countries in the last 50 years or so.
Crawling inflation: The one which is low and which moves up and down
slowly. This is the common form currently.
STABILISATION POLICY: INFLATION MANAGAMENT
Stabilising the price level so as to avoid secular stagnation and secular
inflation is the prime objective of any Government. The main instruments of
stabilisation policy are:
(a) Monetary policy
(b) Fiscal policy
(c)Direct controls
Instruments of Monetary Policy
The instruments of monetary policy are of two types: first, quantitative, general
or Indirect; and second qualitative, selective or direct. They affect the level of
aggregate demand through the supply of money, cost of money and availability of
credit.
Bank Rate Policy: The bank rate is the minimum lending rate of the central
bank at which it rediscounts first class bills of exchange and government securities
held by the commercial banks. When the central bank finds that inflationary
pressures have started emerging within the economy, it raises the bank rate.
Borrowing from the central bank becomes costly and commercial banks borrow less
from it. The commercial banks, in turn, raise their lending rates to the business
community and borrowers borrow less from the commercial banks. There is
contraction of credit and prices are checked from rising further.
Open Market Operations: Open market operations refer to the sale and
purchase of securities in the money market by the central bank. When prices are
rising and there is need to control them, the central bank sell securities. The
reserves of commercial banks are reduced and they are not in a position to lend
more to the business community. Further investment is discouraged and the rise in
prices is checked.
101
Changes in Reserve Ratios: Every bank is required by law to keep a certain
percentage of its total deposits in the form of a reserve fund in its vaults and also a
certain percentage with the central bank. When prices are rising, the central bank
raises the reserve ratio. Banks are required to keep more with the central bank.
Their reserves are reduced and they lend less. The volume of investment, output
and employment are adversely affected.
Selective Credit Controls: Selective credit controls are used to influence
specific types of credit for particular purposes. They usually take the form of
changing margin requirements to control speculative activities within the economy.
When there is brisk speculative activity in the economy or in particular sectors in
certain commodities, and prices start rising, the central bank rises the margin
requirement on them. The result is that the borrowers are giving l ess money in
loans against specified securities.
FISCAL POLICY
Fiscal policy is a powerful instrument of stabilisation. “By fiscal policy we refer
to the government actions affecting its receipts and expenditures which we
ordinarily take as measured by the government’s net receipts, its surplus or deficit”.
The government may offset undesirable variations in private consumption an
investment by anti-cyclical variations of public expenditures and taxes.
Instruments of Fiscal Policy
Fiscal policy through variations in government expenditure and taxation
profoundly affects national income, employment, output and prices. An increase in
public expenditure during depression adds to the aggregate demand for goods and
services and leads to a large increase in income via the multiplier process; while a
reduction in taxes has the effect of raising disposable income thereby increasing
consumption and investment expenditures of the people. On the other hand, a
reduction of public expenditure during inflation reduces aggregate demand,
national income, employment, output and prices; while an increase in taxes tends
to reduce disposable income and thereby reduces consumption and investment
expenditures. Thus the government can control deflationary and inflationary
pressures in the economy by a judicious combination of expenditure and taxation
programmes. We discuss below the various instruments of fiscal policy.
Direct Controls
The aim of direct controls is to ensure proper allocation of scarce resources for
the purpose of price stabilization. They are meant to affect strategic points of the
economy. They affect particular consumers and producers. Such controls are in the
form of licensing, rationing, price, and wage controls, export duties, exchange
controls, quotas, authorization, anti-hoarding control, monopoly control, etc. They
are more effective in overcoming bottlenecks and shortages arising from inflationary
pressures. Their success, however, presupposes the existence of an efficient and
honest administration. Otherwise, they lead to black marketing, corruption, long
102
queues, speculation, etc. Therefore, they should be resorted to only in emergencies
like war, crop failures and hyper-inflation.
12.3.2 Deflation
From the beginning of the present century, many countries have been facing
the opposite threat—deflation. It must be impressed that deflation is really worse
than inflation. Recessions generally occur when there is a widespread drop in
spending often following an adverse supply shock or the bursting of an economic
bubble. Governments usually respond to recessions by adopting expansionary
macroeconomic policies, such as increasing money supply, increasing government
spending and decreasing taxation.
This is explained through the costs of deflation—some of which are highlighted
below.
a) Deflation causes real wage to rise, which tends to raise unemployment and
reduce profit, which in turn, triggers investment fall and thereby a fall in
aggregate demand and income and increase in unemployment.
b) Deflation leads to an increase in real interest rate, which tends to raise the
cost of debt and thereby discourages investment, causing income to fall and
unemployment to rise.
c) Deflation causes the expected price fall, which, in turn, causes consumption
and investment to fall and aggregate supply to rise. The latter two events
reinforce each other to cause price to fall further.
d) Deflation tends to redistribute income in favour of creditors and fixed income
groups (like pensioners, widows and salary earners to some extent) whose
marginal propensity to consume is relatively lower, it tends to lower
consumption, aggregate demand and real income.
The factors given above are obviously very harmful to any economy and
therefore all governments, including the United States, are currently trying their
best to overcome the deflationary threat. Interest rates have been reduced
considerably throughout the world in the last three or four years and currently the
federal fund rate in the United States stands at a 45 years low of 1 percent
FISCAL POLICIES TO OVERCOME DEFLATION
Budget Deficit – Fiscal Policy during Depression: Deficit budgeting is an
important method of overcoming depression. When government expenditures
exceed receipts, larger amounts are put into the stream of national income than
they are withdrawn. The deficit represents the net expenditure of the government
which increase national income by the multiplier times the increase in net
expenditure.
Compensatory Fiscal Policy
The compensatory fiscal policy aims at continuously compensating the
economy against chronic tendencies towards inflation and deflation by
manipulating public expenditures and taxes. It, therefore, necessitates the adoption
103
of fiscal measures over the long-run rather than once-for-all measures at a point of
time. When there are deflationary tendencies in the economy, the government
should increase its expenditures through deficit budgeting and reduction in taxes.
This is essential to compensate for the lack in private investment and to raise
effective demand, employment, output, and income within the economy.
Discretionary Action: Discretionary fiscal policy requires deliberate changes
in the budget by such actions as changing tax rates or government expenditures or
both. It may generally take three forms:
i) changing taxes with expenditures constant,
ii) changing expenditures with taxes constant, and
iii) variations in both expenditures and taxes simultaneously. The first method
is more effective in controlling inflation by raising tax rates and keeping
government expenditure unchanged. The second method is more useful in
controlling deflationary tendencies.
Public Expenditures
We have seen above that all variants of fiscal policy involve public
expenditures. It is therefore, instructive to study the nature and problems of public
expenditures as a stabilizing instrument. Public expenditures are of two types:
(i) compensatory spending, and (ii) pump priming.
Compensatory Spending: is resorted to for the purpose of compensating the
decline in private investment. Any shrinkage in private investment expenditures is
offset by public expenditures on public works and relief measures. Public works are
“durable goods, primarily fixed structures, produced by the government”. They
include roads, airports, railroads, post offices, canals, dams, sewage system, school
and hospital and other buildings, flood and erosion control, parks, etc. Relief
measures are the social security payments like relief payments, subsidies,
unemployment insurance, pensions, etc. When private investment shows signs of
decline and there is a likelihood of recession, the government should immediately
take up public works programme and increase its expenditure on relief measures.
Pump Priming: is one of the variants of public expenditure. the basic idea is
that public spending may be used in modest and temporary does to “prime to
pump” of economic activity which will sooner or later operate on its own motive
power and bring the economy to the path of steady economic growth without
further public spending. It signifies that a certain volume of public spending will
serve at start up the economic machine, which thereafter will reach satisfactory
level of output on its own power.

development.

2. What is primary sector?
12.6 SUMMARY
Deflation is just opposite of inflation. Deflation causes expected price fall
results in fall in investment and hence in consumption, resulting in aggregate
supply to rise. These events reinforce each other to cause further fall in price level.
Fall in price level is very harmful to the economy and therefore to government.
Compensatory Fiscal Policy and increase in Public Expenditure are the policy
options adopted worldwide.

ORGANIZATIONAL BEHAVIOUR
13.1. INTRODUCTION
Organizational behaviour is a study of human behaviour, attitudes, and
performance in organizations. It divulges the various aspects of motivation, leader
behaviour, power, interpersonal relations and communication, group structure and
problems, learning, attitudes, perception, change process, conflict, job design and
work stress etc. The study involves interaction among the formal structure, the
tasks to be undertaken, the technology employed and the method of carrying out
work, the behaviour of people, the process to management and the external
environment in which an organisation is functioning.
13.2 OBJECTIVES
To understand the meaning and importance of organizational behaviour

13.3.1 Definition and Meaning of Organizational Behaviour
Organizational behaviour is the study of the behaviour of people within an
organizational setting. It involves the understanding, prediction and control of
human behaviour and the factors which influence the performance of people as
members of an organisation. The study of it is to utilize it as a tool for human
benefit. It can broadly be applied to the behaviour of people in all types of
organizations, such as those of business, government, and service organizations.
According to Keith Davis, organizational behaviour is the study and application
of knowledge about how people act within organizations. It relates to other system
elements such as structure, technology and the external social environment.
In the words of Stephen P. Robbins, organizational behaviour is the study of
the impact that individuals, groups, and structure have on behaviour, within
organizations, for the purpose of applying such knowledge toward improving the
effectiveness of an organization.
Organizational behaviour is a field of study. This means that it is a distinct
area of expertise with a common body of knowledge. What does it study? It studies
three determinants of behaviour in organizations: individuals, groups, and
106
structure. Organizational behaviour is an applied study. It applies the knowledge
gained about individuals, groups, and the effect of structure on their behaviour in
order to make organizations work more effectively.
13.3.2 Basic Approaches of Organizational Behaviour
The study of organizational behaviour mainly tries to integrate four basic
elements viz. people, structure, technology, and the environment, therefore, it rests
on an interdisciplinary foundation of fund -concepts about the nature of people and
organizations. Thus the basic approaches and dimensions in which the subject can
be understood are as follows:
1. Interdisciplinary Approach: The study of organization behaviour cannot be
undertaken in terms of a single discipline atone. It is necessary that the approach is
interdisciplinary, and through behavioural sciences. It brings together social sciences
and other disciplines that contribute to its study. It appropriates from these disciplines
ideas that will improve the relations between people and organizations. The interest of
various social sciences in people is sometimes expressed by the general term
"behavioural science" which represents the systematized body of knowledge pertaining
to why and how people behave as they do.
2. Human Resource Approach: The human resource approach is
developmental. It is concerned with the growth and development of people toward
higher levels of competency, creativity and fulfillment, because people are the
central resource any organisation and in any society. This, approach can be very
easily understood by comparing it with the traditional management approach where
the manager decides to do something and then gets it done through people
according to his directives and under his strict control and supervision without
taking his workers into confidence just to satisfy his whims. The human resource
approach, on the other hand, is developmental and facilitative. It help people grow
each developing self-control responsibilities and other in them so as to create a
climate where all can contribute to the orgnisation to the limits of their improved
abilities. It will get satisfaction by making fuller use of their capabilities. It is similar
McGregor's theory.
This approach is also known as the supportive approach because in this approach
manager’s role changes. He does not control the employees get the work done, he rather
supports them to grow according to the abilities. Supportive managers provide a good
organizational climate in which people can grow and be productive.
3. Contingency Approach: Traditional management relied on principles to
provide a "one best-way" of managing. There was a correct way to organise, to
delegate, and divide work regardless of the type of organisation or situation
involved. Management principles were considered universal. As the field of study of
organizational behaviour developed the concept of universality gained support.
Behavioural ideas, it was thought, can apply to any type of situation; for example
an employee-oriented leadership should consistently be better than a task oriented
leadership, whatever the circumstances
107
The widely accepted view now is that there are only a few across the board-
concepts that apply to all situations, it has been found are much more complex
than first perceived, and different variables require different behavioural
approaches. The result is the contingency approach to organizational behaviour,
which holds that different situations require different behavioural practices for
effectiveness.
It is presumed that there is no one best way. Each situation must be analysed
carefully to determine the significant variables that exist in order to establish the
kinds of practices that will be more effective. The strength of the contingency
approach is that it encourages analysis of each situation prior to action, while
discouraging habitual practices based on universal assumptions about people in
organizations.
4. Productivity Approach: Most organizations now-a-days try to be
productive, so it is productivity that governs organizational behaviour. Productivity
is a ratio that compares units of output with units of input. If more can be
produced from the same amount of input, productivity is improved or alternately if
lesser input can produce the same output, productivity has increased. The idea of
productivity does not imply that one should produce more, rather, it is a measure
of how efficiently one produces whatever output is desired. Consequently, better
productivity is a valuable measure of how well resources are used by the society. It
means that as a lesser quantity is consumed to produce each unit of output, there
is minimum waste and better management of resource.
Productivity is often measured in terms of economic input and output, but
human and social input and output also are important. For example, it better
organizational behaviour can improve job satisfaction a human output or benefit
occurs. In the same manner, when employee development programmes lead to a by-
product viz. better citizens in a community, a valuable social output results.
Organizational decisions typically involve human, social and/or economic issues,
and productivity is usually a significant part of these decisions.
5. System Approach: While classical theorists paid too much attention to the
structure of organisation, the human resource experts people paid attention solely
to the feelings and attitudes of the workers. What was missing in understanding
management was the simultaneous examination of the structural as well as the
human aspects of the organisation. The system theory people argue that an
organisation is a purposeful system with several sub-systems which are, closely
interconnected. Any action that is taken to solve the problems of one sub-system
will have its repercussions on other sub-systems as well, since all the parts of the
organisation are closely interconnected.
The supporters of this approach identified five sub systems: (1) the production
sub-system which attends to all the production tasks of the organisation (2) the
maintenance sub-system which offers stability and predictability via the proper
selection of employees, the inspection of incoming raw materials, and the like (3)
108
the boundary sub-system & interactions with the external environment are carried
out to monitor changes that take place in the economic, social, technological,
market and other significant environments lacing the organisation. (4) The adaptive
sub-system which deals with the concerns of long-range planning and innovations;
and (5) the managerial sub-system which cuts across all of the functions mentioned
above.
Thus the systems approach envisions the organisation as a purposeful system
with its five sub-systems which should operate in unison because of their
interconnection in achieving the goals of the organisation. The systems theorists,
primary among them, Katz and Kahn (1966), describe organisation as "open to
external environment" receiving certain "inputs" from the environment such as
human resources, raw materials and other necessary ingredients to run the
organisation, engaging in operations that transform the inputs into the final
product; the process known as "throughputs", and finally turning out the 'outputs"
in its final form to be sent back to the environment The organisation, since open to
the environment, also receives "feedback" from the environment and takes
corrective action as necessary and it can be applied especially to the social system
of the organisation.
13.3.3 Importance of Organisational Behaviour
People: The success and failure of an organisation mainly depends upon the
type of people with which it is working people make up the internal social system of
the organisation. They consist of individual employees who are expected to perform
the tasks allotted to them, the groups (may be small or large) who work as teams
and have the -responsibility for getting the job done. Besides, these groups or be
unofficial, informal groups and more official, formal ones. Groups are dynamic.
They form, change, and disband. The human organisation today is not the same as
it was yesterday, or the day before. People are the living, thinking, feeling beings
who work in the organisation to achieve their objectives. Organizations exist to
serve people, rather than people existing to serve organizations.
Structure: Structure refers to the formal or official relationships of people in
the organisation. Different jobs are required to accomplish all of an organisation
activities. There are managers and employees, accountants and assemblers. These
people have to be related income structural way so that their work can effectively be
co-ordinated. These relationships create complex problems of co-operation,
negotiation, and decision- making. The structure of the organisation has to fit with
several other factors such as the technology, size and the environment facing the
organisation in order for the system to be effective. Hence, managers have to deal
with and manage the structural aspects of the organisation as wel1.
Technology: Technology is the mechanism by which the end product or
service of the organisation is produced. It provides the resource with which people
work and affects the tasks that they perform. People cannot perform or accomplish
much with their bare hands, so they build buildings, design machines, create work
109
procedures and assemble resources. The technology used has a significant
influence on working relationships. An assembly line is not the same as a research
laboratory; and a steel mill does not have the same working conditions as a
hospital. The great advantage of technology is that it allows people to do more and
better work, but it also restricts people in various ways. It has costs as well as
benefits. Thus, managing technology is an important component of effective and
efficient performance.
Environment: No single organisation exists alone and isolated. Rather all
organizations operate within an external environment. It is part of a larger system
that contains many other elements such as government, the family, and other
organizations. All of these mutually influence each other in a complex system that
creates a context for a group of people. Individual organizations, such as a factory
or a school, cannot escape being influenced by this external environment. It
influences the attitudes of people, affects working conditions, and provides
competition for resources and power. It must be considered in the study of human
behaviour in organizations and more particularly in the work context.
13.3.4. Fundamental Concepts of Organizational Behaviour
In order to understand the object of organizational behaviour comprehensively,
it is needed to thoroughly study the fundamental concepts revolving around the
nature of people and organisation. A summary of these ideas follows in the
following paragraphs.
The nature of people
With regard to people, there are four basic concepts: individual differences, a
whole person concept, motivated behaviour and the value of the person. Koith
Davis analyses the assumptions about the nature of people as under;
a) Individual Differences: All individuals in the universe are different from
each other. This is a fact even supported by science. The idea of individual
differences comes basically from psychology. Individual differences mean that
management can get the greatest motivation among employees by treating them
differently. If it were not for individual differences, some standard across-the-board
way of dealing with employees could be adopted, and minimum judgement would
be required hereafter. Individual differences require that a manager's approach to
employee should be individual, not statistical. This belief that each person is
different from all others is typically called the law of Individual differences.
b) Whole Person Concept: Although some organisations may wish they could
employ only a person's skill or brain they actually employ a whole person, rather
than certain characteristics. Different human traits may be separately studied, but
in the final analysis they are part of one system making up a whole person. Skill
does not exist apart from background or knowledge. Home life is not totally
separable from work life, and emotional conditions are separate from physical
conditions. People function as a total human being.
110
If the management practises organizational behaviour of various techniques, it
implies that, it is trying to develop a better employee but also it wants to develop
better person in terms of growth and of fulfilment. Jobs in organizations shape
people somewhat as people perform them, so management needs to be concerned
about its effect on the whole person. Employees belong to many organ izations other
than their employees, and they play many roles inside and outside the firm. If the
whole person can be improved then benefits will extend beyond the firm into the
larger society in which each employee lives.
c) Motivated Behaviour: An important determinant of individual behaviour
and performance in an organisation is motivation. From psychology it can be
learned that normal behaviour of Individuals has causes closes may relate to a
person's needs and/or the consequences that result from acts. In the case of needs,
people are motivated not by what we think they ought to have but by what they
themselves want. To an outside observer a person's needs may be realistic, but they
are still controlling. This fact leaves management with basic ways to motivate
people. It can show them how certain actions will increase their need fulfilment, or
it can threaten decreased need fulfilment if they follow an undesirable course of
action. Clearly a path toward increased need fulfilment is the better approach.
Motivation is an essential stimulant through which the operations of an
organisation can be accomplished. No matter how much modern technology and
equipment an organisation has, these things cannot be put use until they are
released and guided by people who have been effectively motivated towards the
expected ends.
d) Value of the person: This concept is of a different order from the other
three because it is more an ethical philosophy than a scientific conclusion. If
mainly asserts that people are to be treated differently from factors of production
because they are of a higher order in the universe. It recognises that because
people are of a higher order, they want to be treated with respect and dignity. Every
job, irrespective of its natures the people who do it to proper respect and
recognition of their unique aspirations and abilities. The concept of human dignity
rejects the old idea of treating, employees simply as economic tools. Since
organizational behaviour always involves people, ethical philosophy is involved in
one way or another in each action. Human decisions cannot be made apart from
values.
The Nature of Organizations
Organizations are the outcome of interactions among people. So with two
organizations, the two key concepts are that they are social entities and that they
are formed on the basis of give and take principle. The nature of organisation
embodies two basic assumptions as quoted by Davis, relating to
1. Social systems: It can be learned from sociology that organizations are the
social systems in which individuals and groups fill their roles, and perform the
activities therein. These roles and activities are governed by social laws as well as
111
psychological laws. Just as people have psychological needs they also have the
social roles and status. Then behaviour is influenced by their group as well as their
individual drives and motives. In fact two types of social systems exist side by side
in organizations. One is the formal social system and the other is the informal
social system
The existence of a social system implies that the organizational environment is
one of dynamic change, rather than a static set of relations, parts of the system are
interrelated, interdependent and subject to influence by any other. The idea of a
social system provides a framework for analysing organizational behaviour. It helps
make organizational behaviour problems understandable and manageable and
finally to achieve the organizational goals effectively.
2. Mutual benefit: Mutual benefit is represented by the statement
organizations need people, and people also need organizations any organisation
irrespective of its nature and type has human purpose. They are formed and
maintained on the basis of some mutuality of interest among their participants.
People see organizations as a means to help them reach their goals, while
organizations need people to help reach organizational objectives. If give and take
between organisation and employees working therein is lacking, it makes no sense
to try to assemble a group and develop co-operation. It also provides a
superordinate goal that integrates the efforts of individuals and groups. The result
is that they are encouraged to attack organizational problems rather than each
other. Indeed, this mutuality of interests provides a superordinate goal and forms a
basis for mutual cooperation. The same can be seen in the following
Mutual interest provides a superordinate goal for employees and the
organisation.
Holistic organizational behaviour
When the six fundamental concepts of organizational behaviour are considered
together, they provide a holistic concept of the subject. Holistic organizational
behaviour interprets people-organisation relationships in terms of the whole
person, whole group, whole organisation, and whole social system. It takes an
across - the-board view of people in organizations in an effect to understand as
112
many as possible of the factors that influence their behaviour. Issues are analysed
in terms of the total situation affecting them rather than in terms of an isolated
event of problem.
Historical origins
As quoted by Keith Davis in his book "Human Behaviour at work" that
although human relations have existed since the beginning of time, the art and
science of trying to deal with them in complex organisation is a relatively recent
origin. In the early days people worked hard alone or in such small groups that
their work relationships were easily understood and handled. It has been popular
to assume that under these conditions people worked in a Utopia of happiness and
fulfilment, but this assumption is largely a nostalgic reinterpretation of history.
Actual conditions were brutal and back breaking. People worked from morning till
evening under intolerable conditions of disease, filth, danger, and scarcity of
resources. They had to work this way to survive, and very little effort was devoted to
their job satisfaction.
Then came the industrial revolution. In the beginning, the conditions of people
did not improve, but at least the seed was planted for potential, improvement.
Industry expanded the supply of goods and knowledge that eventually gave workers
increased wages, shorter hours, and more work satisfaction. In this new industrial
environment Robert Owen, a Welsh factory owner, about the year 1800, was one of
the first to emphasize human needs of employees. He refused to employ young
children. He brought his workers cleanliness and temperance and improved their
working conditions. This could hardly be called modern organizational behaviour,
but it was a beginning. He was called "the real father" of personnel administration
by an early writer.
Andrew Ure incorporated human factor into his philosophy of manufactures in
1835. He recognised the mechanical and commercial parts of manufacturing but he
also added a third factor, which was the human factor. He provided workers with
hot tea, medical treatment, "a fan apparatus" for ventilation, and sickness
payments. The ideas of Owen and Ure were accepted slowly or not at all, and they
often, deteriorated into a paternalistic do- good approach rather than a genuine
recognition of the importance of people at work.
Scientific management movement
It was in the latter part of the nineteenth century when the human element in
organizations attracted marked attention. It was awakened by Frederick. W. Taylor
in the United States. He is often called "the father of scientific management", an d
the changes he brought to management paved the way for later development of
organizational behaviour. Prior to this workers were considered as slaves to be
purchased and sold in the market and very little attention was paid to them as
human beings. Taylor's main concern was with the efficiency of both workers and
management. He believed that his methods of scientific management would lead to
113
improved management-labour relations, and contribute to improved industrial
efficiency and prosperity
Taylor adopted an instrumental view of human behaviour together with the
application of standard procedures of work. Workers were regarded as rational,
economic beings motivated directly by monetary incentives linked to the level of
work output. Workers were viewed as isolated individuals and more as units of
production to be handled almost in the same way as machines. Hence, scientific
management is often referred to as a machine theory model. This movement
overlooked the significance of interpersonal behaviour in work settings.
The contributions made by Taylor continue to evoke much criticism and
comment by many management experts. As M. Rose argues Taylor's diagnosis of
the industrial situation was based on the single theme inefficiency. Among his
criticisms are that Taylor selected the best workers for his experiments and
assumed that workers who were not good at one particular task would be best at
some other task. There is, however, not certainty of this practice. Taylor regarded
workers from an engineering view point and as machines, but one best way of
performing a task is not always the best method for every worker. Rose also argues
that the concept of a fair day's pay for a fair day's work is not purely a technical
matter. It is also a notion of social equity and not in keeping with a scientific
approach.
The Hawthorne studies
It was in the 1920s and 1930s that stand out as a landmark in the history of
human behaviour at work when the Hawthorne studies' were conducted at Western
Electric company in America by Elton Mayo and R.J. Roethlisberger at Harvard
University. They gave an academic stature to the study of human behaviour at
work. The result of these studies was the concept that an organisation is a social
system and the worker is indeed the most important element in it. Their
experiments showed that the worker is not a simple tool but a complex personality
interacting in a group situation that often is difficult to understand.
There were four main phases to the Hawthorne experiments.
a) The Illumination Experiments: The original investigation was conducted
on the lines of the classical approach and was concerned, in typical scientific
management style, with effect of the intensity of lighting upon the workers
productivity. The workers were divided into two groups, one is an experimental
group and the other a control group. The net result of these tests were inclusive as
production in experimental group varied with no apparent relationship to the level
of lighting, but actually increased when conditions were made much worse.
Production also increased in the control group although the lighting remained
unchanged. The level of action was influenced, clearly by factors other than
changes in physical conditions of work. This prompted a series of other experiments
' investigating factors of worker productivity.
114
b) The Relay Assembly Test Room: In the relay assembly test room the work
was boring and repetitive. It involved assembling telephone relays of putting
together a number of small parts. A control room was setup for the purpose, in
which measurement could be taken of humidity, illumination and other physical
factors. Six women workers were transferred from their normal departments to a
separate area. This group of six was segregated from others and also insulated from
the traditional practices of management. The experiment was divided into 13
periods during which the workers were subjected to a series of planned and led
changes to their conditions of work, such as reducing of work, rest pauses and
provision of refreshments. The general environmental conditions of the test room
were similar to those of the normal assembly line. During the experiment the
observer adopted a friendly manner, consulting with the workers, listening to their
complaints and keeping them informed of the experiment, following all but one of
the changes there was continuous increase in the level of production. The
researchers formed the conclusion that (1) better and more sympathetic
supervision, (2) closer and more informed interpersonal relation among the group,
(3) greater autonomy of the group as well as its members, and (4) a sense of
belonging promoted in them.
c) Mass interviewing programme: Another significant phase of the
experiments was the interviewing programme. The test room studies showed that
the type of supervision influenced morale. So the problem was how to improve
supervision? Why not get the frank opinions of the workers themselves on this
issue?
Accordingly, the programme was taken up of interviewing them. It had two
phases. In the first phase from September 1928 to the middle of 1929 it was the
direct type interview i.e. they were asked a few specific questions, to which the
answers were supposed to reveal their attitudes. It was found in course of these
interviews that the workers wanted to speak about many other things than those
embodied in the pre-determined questionnaires. So second phase of the interview
programme was launched in the later part of 1929. It was the depth or non
directive interview, in which the interviewer instead of asking the worker set
questions, encouraged him to talk freely on topics of his own choice. The average
length of the depth interview was one and a half hours, compared to only 30
minutes in the earlier straight interview. By 1931 over 20,000 employees were
interviewed separately many of them twice, informally and in confidence, with the
onset of the Depression, however, this programme was suspended.
The main conclusions arrived at experiments were that the supervisors should
be trained in such a way that they do not behave with the workers as their bosses.
Instead they should be kind and sympathetic to them. They should be trained more
to listen to talk, to be more result oriented, more concerned with the workers and
more skilled in handling social personal situations.
115
d). Bank Wiring Group Observation: The earlier investigations had revealed
that informal groups among workers could influence to a great extent the behaviour
of their individual members. An important trend in such behaviour was restriction
of output. So the experimenters wanted to ascertain how a group could put
pressure on an individual member for lowering production in a high-incentive
system. Accordingly, the Bank wiring Group was set up and its behaviour was
studied for seven months from November 1931 to May 1932.
The group chosen for study comprised 14 men operators who assembled
switches for central office switchboard equipment. It was noted that the men
formed their own informal organisation with sub-groups or cliques, and with
natural leaders emerging with the consent of the members. The group developed its
own pattern of informal social relations and 'norms' of what constituted proper'
behaviour. Despite a financial incentive scheme where the workers could receive
more money for more produce, the group decided on a level of output well below the
level they were capable of producing. Group pressures on individual workers were
stronger than financial incentives offered by management. The group believed that
if they increased their output management would raise the standard level of rates.
The new emphasis on people at work was a result of trends that had been
developing over a long period of time. It helped bring human values into balance
with other values at work. But unfortunately, the term human relations' gradually
lost favour, although it continues to be used especially at the operating level
because of its appropriateness. An example is the statement. 'The supervisor is
effective with human relations. As the field became more mature and research-
based, the new term that arose to describe it was Organizational behaviour".
13.3.5. Role of Behavioural Science
The behavioural science offers several ideas to management as to how human
factor should be properly emphasised to achieve organizational objectives. Human
factor is not merely an instrument in the organisation but the very core of
organizational existence. An organisation is a conscious interaction of two or more
persons. This suggests that since organisation is the interaction of persons, they
should be given adequate importance in managing the organisation. This becomes
more important specially because of the changing dimensions of human behaviour,
changing from money-motivated behaviour to multi-motivated behaviour. The
changing behavioural pattern suggests that organizational structure and process
should be based on human characteristics. From this point of view managers must
understand the behavioural pattern of the people. Behavioural science provides this
opportunity by analysing human behaviour for understanding and prescribing
means for shaping human behaviour a particular direction.
Understanding Human Behaviour
Behavioural science provides a way for understanding human behaviour in the
organisation. For shaping human behaviour in definite direction for achieving
certain predetermined objectives, managers must know how the people in the
116
organisation behave. Behavioural science paves the way for understanding human
behaviour in all the directions in which beings interact. Thus human behaviour can
be understood at the dual level, interpersonal level, group level and intergroup
level.
1. Individual Level: The behaviour of human beings as social men is first
issue in behavioural science. It offers for analysing why and an individual behaves
in a particular way. As will be seen later, human behaviour is a complex
phenomenon and is affected by a large number of factors - psychological, social,
and cultural, and others. Behavioural Science integrates these factors to provide
simplicity in understanding human behaviour.
2. Interpersonal Level: Human behaviour can be understood at the level of
interpersonal interaction. Such interpersonal interaction is normally in paired
relationship which represents man's most natural attempt at socialisation. When
one focuses on the influence of one's peer and its effect in working relationship, or
examines the two-person subordinate relationship, it is obvious that the two-person
relationship is inevitable in the organisation. Behavioural Sci ence contributes
means for understanding these interpersonal relationships in the organisation.
Analysis of reciprocal relationship, role analysis, and transactional analysis are
some of the common methods which provide such understanding.
3. Group Level: Though people interpret anything at their individual level,
they are often modified by group pressures which thus becomes a force in shaping
human behaviour. Thus individuals should be studied in group also. Research in
group dynamics has contributed vitally to the behavioural science and shows how a
group behaves in its norms, cohesion, goals, procedures, communication pattern,
leadership, and membership. These research results are furthering managerial
knowledge understanding group behaviour which is very important for
organizational morale and productivity.
4. Intergroup Level: The organisation is made up of many groups that develop
a complex of relationship to build its processes and substance. Understanding the
effect of group relationships is important for managers in today's organisation. Inter
group relationship may be in the form of co-operation or competition. The co-
operative relationships help the organisation in achieving its objectives. Behavioural
science provides means to understand and achieve co-operative group relationships
through interaction, rotation of members among groups, avoidance of win -lose
situation, and focus on total group objectives.
Controlling and Directing Behaviour
After understanding the mechanism of human behaviour, managers are
required to control and direct the behaviour so that it conforms to standards
required for achieving organizational objectives. Thus managers are required to
control and direct the behaviour at all levels of individual interaction. For this
purpose, behavioural science helps managers in many areas: use of power and
117
sanction, leadership, communication, and building organisation climate conducive
for better interaction.
1. Use of Power and Sanction: Organizational behaviour can be controlled
and directed by the use of power and sanction which are formally prescribed by the
organisation. Power is referred to as capacity of an individual to take certain action
and may be utilised in many ways. The use of power is related with sanction in the
organisation. However, more use of power and sanction in the organisation is not
enough for directing human behaviour. Moreover, these can be used in several
ways and not all ways are equally effective. Behavioural science explains how
various means of power and sanction can be utilised so that both organizational
and individual objectives are achieved simultaneously.
2. Leadership: Another method of bringing human behaviour in tune with
organizational requirement is leadership. Today, the difference between a
successful and failing organisation lies in the quality of leadership of its managerial
personnel. Behavioural science brings new insights and understanding to the
practice and theory of leadership. It identifies various leadership styles available to
a manager and analyses which style is more appropriate in a given situation. Thus
managers can adopt styles keeping in view the various dimensions of organizations,
individuals, and situations.
3. Communication: Communication is the building blocks of an organisation.
It is communication through which people come in contact with others. People in
the organisation, particularly, at higher level spend considerable time in
communication. To achieve organizational effectiveness, the communication must
be effective. The communication process and how it works in interpersonal
dynamics has been evaluated by behavioural science. The factors that affect
communication have been analysed so as to make it more effective.
4. Organizational Climate: Organizational climate refers to the total
organizational situations affecting human behaviour. Organizational climate takes a
systems perspective and affects human behaviour. Behavioural science suggests
the approach to create organizational climate, in totality rather than merely
improving the physiological conditions organising employee satisfaction by
changing isolate work process. Satisfactory working conditions, adequate
compensation, and the necessary equipments for the job are viewed as only small
part of the requirements for sound motivational climate. Other greater importance
are the creation of an atmosphere of effective supervision, the opportunity for the
realisation of personal goals, congenial relations with others at the work and a
sense of accomplishment. Thus, behavioural science has discovered a new
approach of managing people in the organisation.
5. Organizational Adaptation: Organizations as dynamic entities are
characterised by pervasive change. In this age of environmental variability, real job
of a manager is to provide continuity in organizations because organizations have to
adapt themselves to the environmental changes making suitable internal
118
arrangements. However, such organizational arrangements are mostly resisted by
the internal people. Thus, managers have to face dual problems, identifying need
for change and then implementing the changes without adversely affecting the need
satisfaction organizational people. Behavioural science has the ongoing process as
its goal. It is also the essence of managing change. Management of change is seen
as a self- perpetrating ever-evolving phenomenon.
13.3.6. Constraints or limitations of organizational behaviour and managerial performance
In the words of Keith Davis, organizational behaviour primarily emphasizes
only on the human side of organizations and the kinds of benefits that attention to
it can bring. Further he says organizational behaviour will not absolutely abolish
conflict and frustration among the employees in the organisation but it can only
reduce them. It is a way to improve the whole not an absolute answer to problems.
Furthermore, it is part of cloth of an organisation. We can discuss organizational
behaviour as a separate subject, but to apply it we must tie it back to whole reality.
Improved organizational behaviour will not solve unemployment. It will not make
up for our own deficiencies. It cannot substitute for poor planning, input
organisms, or inadequate controls. It is only one of many factors operating within a
larger social system.
The major constraints of organizational behaviour can be discuss under.
Behavioural Bias: People who lack system understanding may develop a
behavioural bias, which gives them a narrow view point that emphasizes satisfying
employee experiences while overlooking the broader system of the organisation in
relation to all its public. This condition is often called as 'tunnel vision' because
view points are narrow, as if people were working through a tunnel. They see only
the view at the other end of the tunnel while missing the broader landscape.
It should be evident that concern for employees can be so greatly overdone
that the original purpose of joining people together productive organizational
outputs for society - is lost. Sound organizational behaviour should help achieve
organizational purposes, not replace them. The person who ignores the needs of
people as consumers of organizational outputs while championing employees needs
is misapplying the ideas of organizational behaviour. It is also true that the person
who pushes production outputs without regard for employee needs is misapplying
organisation behaviour. Sound organizational behaviour recognises a social system
in which many types of human needs are served in many ways.
Behavioural bias can be so misapplied that it harms employees as well as the
organisation. Some people, inspire of their good intentions, so overwhelm others
with care that they are reduced to dependent and unproductive - indignity. They
become content not fulfilled. They find excuses for failure, rather than taking
responsibility for progress. As happened with scientific management years ago
concern for people can be misapplied by over eager partisans until it becomes
harmful.
119
Thus, employees as well as managers can handicap a fellow employee through
unrestricted concern and care.
The law of diminishing returns: Over emphasis on organizational behaviour
practice may produce negative results as indicated by the law of diminishing
returns. It is a limiting factor in organizational behaviour the same way that it is in
economics. In economics the law of diminishing returns refers to a declining
amount of extra outputs when more of a desirable input is added to an economic
situation. After a certain point, the output from each unit of added input tends to
become smaller. The added output eventually may reach zero and even decline
when more units of input are added.
The law of diminishing returns in organizational behaviour works in a similar
way. It states that at some point increases of a desirable practice produce declining
returns, eventually zero returns, and then negative returns as more increases are
added. The concept implies that for any situation there is an optimum amount of a
desirable practice such as participation. When that point is exceeded, the re is a
decline in returns. In other words, the fact that a practice is desirable does not
mean that more of it is more desirable. More of a good thing is not necessarily good.
Diminishing returns may not apply to every human situation, but the idea
applies so widely that it is of general use. Furthermore, the exact point at which an
application becomes excessive will vary with the circumstances but an excess can
be reached with nearly any practice.
Generally one question may be raised saying that why does the law of
diminishing returns exist? Essentially, it is a system concept. It applies because of
the complex system relationships of many variables in a situation. The facts state
that when an excess of one variable develops, although that variable is desi rable, it
tends to restrict the operating benefit of other variables so substantially that net
effectiveness declines. For example too much security may lead to less employee
initiative and growth. This relationship shows that organizational effectiveness is
achieved not by maximizing one human variable but by working all system
variables together in a balanced way.
Employee autonomy as an example. Employee autonomy is a higher - order
need that is frequently emphasized. Some observers speak autonomy as an ideal,
implying that, if employees could have complete autonomy, then the ideal state
would be achieved, but this kind of reasoning ignores the law of diminishing
returns. As shown in figures effectiveness tends to decline when too much
autonomy occurs. On reason probably is that, excess autonomy prevents
coordination toward central goals. Different units of the organisation cannot work
together, the labour of employees is wasted.
At the end of the continuum, the lack of autonomy also is ineffective. When
autonomy declines below an appropriate level, the organisation fails to develop and
use the talents of employees. The result is that effectiveness declines with both
excessive use and miserly use of autonomy. Most success is gained in the broad
120
middle ground of use. This relationship produces a humpback curve for autonomy
when it is chatted with effectiveness.
The law of diminishing returns serves as a warning that although increases in
desirable practices can be beneficial, an excess of any of them will be
counterproductive. Moderation is required. People observed with building only
autonomy or creating maximum. Employee security will not be contributing to
organizational success. There can be too much of a good thing just as there can be
too little of it.
Other problems: One problem that has plagued organizational behaviour has
been the tending for business firms to have short time horizons for the expected
pay off from behavioural programmes. This search for a 'quick fix' sometimes leads
managers to embrace the newest fad to address the symptoms while neglecting
underlying problems or to fragment their efforts within the firm. The emergence of
organizational development programmes that focus on system wide change and the
creation of long-term strategic plans for the management of human resources have
helped bring about more realistic expectations concerning employees as a
productive asset.
Another challenge that confronts organizational behaviour is to see whether
the ideas that have been developed and tested during periods of organizational
growth and economic plenty will endure with equal success under new conditions.
Specifically, the environment in the future may be marked by some shrinking
demand, scare resources, and more intense competition. When organizations
stagnate, decline, or have their survival threatened, there is evidence that stress
and conflict increase. Will the same motivational models be useful in these
situations? Are different leadership styles called for? Will the trend toward
participative processes be reversed? Since no easy answers to these and many
other questions exist, it is clear that there is still tremendous room for further
development of organizational behaviour.
Manipulation of people: A significant concern about organizational behaviour
is that its knowledge and techniques can be used to manipulate people as well as to
help them develop their potential. People who lack respect for the basic dignity of
human being could learn organizational behaviour ideas and use them for selfish
ends. They could use what they know about motivation or communication to
121
manipulate people without regard for human welfare. People who lack ethical
values could use people in unethical ways.
The philosophy of organizational behaviour is supportive and oriented toward
human resources. It seeks to improve the human environment and help people to
grow forward their human potential. However, the knowledge and technique of this
subject may be used for negative as well as positive consequences. This possi bility
of true of knowledge in most any field, so it is no special limitation of organizational
behaviour. Nevertheless, we must be cautions that what is known about people is
not used to manipulate them. The possibility of manipulation means that people i n
power in organizations need to be people of high ethical and moral integrity who
will not misuse their power. Without ethical leadership, the new knowledge that is
learned about people becomes a dangerous instrument for possible misuse. Ethical
leadership will recognise such guides as the following as quoted by Wayne F.
Cascio.
a) Social responsibility, Responsibility to others arises whenever people have
power in an organisation.
b) Open communication: The organisation shall operate as a two-way open
system with open receipt of inputs from people and open disclosure of its
operations to them.
c) Cost-benefit analysis: In addition to economic costs and benefits human and
social costs and benefits of an activity shall be considered in determining
whether to proceed with it.
What is the difference between genuine motivation and manipulation of
people? Basically the conditions of use need to be examined. If people understand
what is happening and have substantial freedom to make their own choices, they
are not being manipulated. But if they are being covertly directed and/or lack free
choices, they are being manipulated. This is true whether the manipulator is a
social scientist, another employee or a manager.
As the general population learns more about organizational behaviour, it will
be more difficult to manipulate them, but the possibility is ways there. That is why
society needs ethical leaders. But ethical leader cannot succeed unless there also
are ethical followers.
13.3.7. Understanding Individual
This heading divulges with understanding individual behaviour in an
organization. It explains the nature of human being as an individual, as an
employee in the organization. The human beings may have several similarities as
well as differences among them. These similarities and differences will have impact
on the behaviour of employees in the organization. The personality of employees
and the determinants of personality which will have an impact on an individual
behaviour are also dealt in this unit. Learning is a process wherein environment
plays a major role. People act as they perceive. Different people perceive things
122
differently. Values play an important role in the study of organizational behaviour
as they lay the foundation to understand perception, attitudes, and personality.
In any human activity, nothing of any consequence happens until an
individual wants to act. The success or failure of any organization depends not only
on the organizational functions - production, finance, marketing and also on the
quality of human character. What individual can accomplish depends to a great
extent on how much and why one wants to act. The individual's will to work is
different from his capacity to work. Management can buy employee's time, his
physical efforts but not his enthusiasm, initiative or loyalty. One of the serious
problems in organizations is to get maximum efforts and contribution of
individuals.
The Individual
The Individual is a person with distinct character and personality traits or
behavioural patterns. Every person has his own individuality, which means that the
individuals who form the groups have individual differences. Obviously, any group
is characterised by individual differences. An individual moves from childhood,
through adolescence, to adulthood; and accordingly his personality attains the
necessary change and maturity. The more the maturity the more the adjustability.
The individual starts his development from the very moment of birth. The
biological factor, sociological factors, historical factors, genetic factors, cultural and
environmental factors as well as heredity substantially influence the developmental
processes of perception, learning and motivation. It ultimately develops a
personality of his own, i.e. any individual has a personality of his own.
The individual develops into adolescence through infancy and childhood.
Freud pointed to the possibility of identifying the basis for adult personality
patterns in the problems of early childhood. Many other thinkers have also
provided identical view of the behaviour of individual in the early norms of test
performance at each age in developing mental abil ity. Regarding individual
development Kolasa's remark seems to be relevant: "Up to age two the child is
immersed in problems of his sensor motor operations. Preconception thought,
where concrete things are recognised a standing for real ones, develops before age
four though classification of these concepts takes place up until age seven. Even at
this age however, the child is tied to concrete states (though in greater number) and
not until approximately age 11 is there a move to abstract thought and use of logic
and hypotheses. While the stages may be too rigidly defined, Piaget’s research does
show the changing nature of the individual and his ability proceed in the world.
Thus, the individual in the process of change to reach his real self as a long line of
transition. Again dogmatic positions may be faced by the individual at certain ages
during the period of maturity.
The basic input for human behaviour is sensation of information. Hence,
development of individual necessitates development of sensational also. Cognitive
process is another critical function in individual behaviour for which the variables
123
like perception, learning, abilities), concept formation, problem solving, language,
etc. are important. Any individual has to develop these qualities in him for an
important cognitive process to take place in him. These qualities, in some
magnitude, are prevalent in every individual. The greater the development of them
the greater would be the cognitive process.
Management and human factor
The functions of management are planning, organizing, motivating, and
controlling. These functions that comprise the management process-a step-by-step
way of doing something-are relevant regardless of the type of organization or level of
management with which one is concerned. As Harold Koontz and Cyril O'Donnell
have said: "Acting in their managerial capacity, presidents, department heads,
foremen, supervisors, college deans, bishops, and heads of governmental agencies
all do the same thing. As managers they are all engaged in part in getting things
done with and through people. As a manager, each must, at one time or another
carry out all duties. The Planning involves setting goals and objectives for the
organization and developing "work maps" showing how these goals and objectives
are to be accomplished. Once plans have been made, organizing becomes
meaningful. This involves bringing together resources-people, capital and
equipment in the most effective way to accomplish the goals. Organizing, therefore,
involves an integration of resources.
Motivating plays a large part in determining the level of performance of
employees, which, in turn, influences how effectively the organizational goals will be
met. Motivating is sometimes included as part of directing, along with
communicating and leading.
William James of Harvard in his study found that hourly employees could
maintain their jobs (that is, not be fired) by working at approximately 20 to 30 per
cent of their ability. His study also showed that employees work at close to 80 to 90
percent of their ability if highly motivated. Both the minimum level at which
employees might work and yet keep their jobs and the level at which they could be
expected to perform with proper motivation. This shows us that if motivation is low,
employees' performance will suffer as much as if ability were low. For this reason,
motivating is an extremely important function of management.
Another function of management is controlling. This involves feedback of
results and follow-up to compare accomplishments with plan and to makes
appropriate adjustments where outcomes have deviated from expectations.
Even though these management functions are stated separately, and as
presented seem to have a specific sequence, one must remember that they are
interrelated. While these functions are interrelated at any one time one or more
may be of primary importance.
Skills of a manager
The three areas of skill necessary for carrying out the process of management
as specified by Paul Hersey and Kenneth H. Blanchard. They are Technical skill,
124
Human skill and conceptual skill. Technical skill -ability to use knowledge,
methods, techniques and equipment necessary for the performance of specific tasks
acquired from experience, education, and training.
Human skill-ability and judgement in working with and through people,
including an understanding of motivation and an application of effective leadership.
Conceptual skill-ability to understand the complexities of the overall
organization and where one's own operation fits into the organization. This
knowledge permits one to act according to the objectives of the total organization
rather than only on the basis of the goals and needs of one's own immediate group.
The appropriate mix of these skills varies as an individual advances in
management from supervisory to top-management positions. To be effective less
technical skill tends to be needed as one advances from lower to higher levels in the
organization but more conceptual skill is necessary. Supervisor at l ower levels need
considerable technical skill because they are often required to train and develop
technicians and other employees in sections. At the other extreme, executives in a
business organization need to know how to perform all the specific tasks at the
operational level. However, they should be able to see how all these functions are
interrelated in accomplishing the goals of the total organization.
While the amount of technical and conceptual skills needed at these different
levels of management varies, the common denominator that appears to be crucial at
all levels is human skill.
Importance of human skills
The human skills were considered unimportant in the past, but they are of
primary importance today. For example, one of the great entrepreneurs John D.
Rockefeller, stated: "I will pay more for the ability to deal with people than any other
ability under the sun". These words of Rockefeller are often echoed. According to a
report by the American Management Association, an overwhelming majority of the
two hundred managers who participated in a survey agreed that the most
important single skill of an executive is ability to get along with people. In this
survey, management rated this ability more vital than intelligence, decisiveness',
knowledge or job skills, management skills necessary at various levels of an
organization.
Nature of man
Human Nature: The term "human nature" refers to the characteristics of
mankind which generally enable us to distinguish humans from animals, from
inanimate objects, and from social abstractions such as society or organization.
The descriptions of human nature, however, vary enormously. Human nature
can be the set of motives, mental and emotional capacities, and psychic
mechanisms common to human being. More broadly speaking, it is a set of human
needs, drives, predispositions, tendencies, propensities, and actual behaviours.
Human nature can be conceptualized in a negative way in the absence of
socialization. This sociological and psychological perspective treats human nature
125
as a source of systematic variance in behaviour. Man's nature can be described in
terms of: Levels; Dialectic; Norms; Innateness; and learning:
(i) Levels: Here mankind is assumed to have a biological nature, a social nature,
and a creative nature (Murphy, 1958).
(ii) Dialectic: Man is seen as having more separate natures, which behave as a
result of their dialectical interaction.
(iii) Norms: With a metaphysical philosophy one can make lists of behaviours
required of humans if they are give evidence of being human.
(iv) Learning: A less restrictive approach to that of the sociobiologisls allows pan-
human learned behaviour to be called part of human nature. Thus a learned
behaviour, is a characteristic of human nature. Human nature is a measure of
central tendency among human not necessarily observable in a given human
being.
(v) Innateness: In this sociobiological approach almost every individual has a set
of genetically determined characteristics which do not diffe rentiate that
individual from others.
Definition
The Greek philosophers described human nature as a rational principle
governing humans in an almost law-like manner. Man is driven to be rational
because the universe is rational. This law- boundedness characteristic of human
nature carried over into the medieval view although the content of the law changed,
mankind was driven not to be rational but to seek out perfect good.
Humans were viewed as purposeful creatures who use reasons to carry out the
dictates of their will. A focus on the passions and emotions emerged, which led to
two opposing views. Mantaigne characterized "human as inconsistent, irresolute,
and untamable". These thinkers could-not envisage any kind of malleability in
human nature which would make humans manageable or teachable in any complex
way. A second view however, stressed the plasticity of man's nature, and believe
that essentially, man's nature could be moulded.
Adoption and selection theories of organizations are based on assumptions
that humans are controlled by their environments, while strategic choice theories
focus on the role of voluntarism.
If human nature is the result of, or caused by, or emerging from something
external to humankind, then it can be called law bound. This means that human
characteristic can be explained, predicted, accounted for, controlled by reference to
metaphysical, biological, historical, cultural, social, or environmental forces.
Alternatively, if human nature is the result of something internal to humankind
then it can be called self bound. In this view human nature emerges out of human
purposiveness or sense making rather than in response to external law.
Similarities and differences among individuals
Individuals differ in personal characteristics and these differences create
difference in work performance and behaviour of individuals at work place.
126
Individuals differ in physical build up, appearance, intelligence attitudes,
personality, interests, motives, skills, training education, job knowledge and skills.
Such differences have their important impact in industry as they affect, the job
behaviour of the people. The behaviour of any individual responds to any particular
situation depending upon what he brings into the situation, in terms of abilities,
education, skills, trainings, desires, interests, habits and understanding.
Psychology assist in studying the difference of one individual with another. People
differing their physical characteristics, intelligence, intellectual attitude, interests,
temperament and in character. Human nature is greatly influenced by the
environment, acquired habits, traits and characteristics. The management can
change the behaviour of persons by changing the work environment and by
educating and by training them. Certainly there are differences between
individuals. Placed in similar situations all people do not act alike. However, there
are certain fundamental similarities underlying the behaviour of all individuals that
can be identified and then modified to individual differences.
Individual difference can be assessed in terms of differences in individual
characteristics. Most prominent among them can be (1) Physical characteristics. (2)
Personality traits, (3) Perception, (4) Attitudes, (5) Emotions, and (6) Memory. The
other characteristics are interests, motivation, behaviour and approaches especially
frustration, role behaviour, the overall personality, and so on. The prominent, ones
are described here.
1. Physical Characteristics: are weight, arm span, vital capacity, strength of
the grip, visual acuity, auditory acuity, fatiguability, appearance and countenance,
facial expressions and gestures, etc. Evaluation of such differences in the physical
characteristics is important so the individual performance generally depends on
such characteristics.
2 Personality: Traits are also known as temperamental or emotional qualities
of a person, can be the essential characteristics of the behavioural pattern of the
individual. These traits are: dominant, cheerful, cowardly, dishonest, timid, honest,
moody, etc. Many such personality traits or characteristics are found in great
magnitude in some persons: especially characteristics like aggressiveness,
persistence, sociability, dominance, helpfulness, orderliness etc. are very dominant
in certain individuals. Some psychologists are of the opinion that personality traits
are different, from emotional traits, character traits of personal traits.
Characteristics like spirituality, honesty, truthfulness, integrity, etc. are character
traits; while emotional maturity, cheerfulness, aggressiveness, neuroticism,
pessimism, etc. are emotional or temperamental traits. Personal traits are specific
and typical ways of an individual's behaviour such as co-operative attitude,
submissiveness, humbleness, meekness, dominance, optimism, etc. Though these
traits can be inborn, they can be achieved through experiences and learning, too.
3. Perception: Differences in perception also substantially differentiate
individuals. There are no two opinions that people differ in their perception ability.
127
What we see is based on the way the brain organises the nervous impulses which
come from the eye. The difference in perception is characterised by difference in
what we see, hear and understand, which is brought about by how the figures are
framed in the process of seeing, hearing and understanding. In this context, it can
be observed that what we perceive depends not only on our power of seeing or
hearing but also the frame of reference in which it is seen or heard. If a person is
exposed to different situations or if different people are exposed to one situation,
their perception is bound to differ. It shows that the perception ability differs from
person to person and from situation to situation. At the same time the manager's
performance efficiency depends on his perception ability. The greater the perception
ability the greater would be the managerial efficiency.
4. Attitude: Attitude is another very important concept in individual
differences on the one hand and, in psychology and organizational behaviour on the
other. It is very often used as an important variable to determine individual
differences.
5. Emotions: Individual differences can be judged in terms of emotional
differences also. Emotion is a complex state involving conscious feeling,
physiological changes, and an evaluation of a given situation as having significance
of some kind for the individual. Many emotions are accompanied by action
tendencies toward approach or withdrawal. For example, if somebody, who is
closely associated with us, behaves in an unexpected and opposite direction from
what we desired of him, then we would be provoked to have a strong feeling of
anger, which is our emotion, in fact, every individual has certain 'wired in'
resources for emotional behaviour that tend to develop in a pattern of emotional
development which, as a matter of fact, can be universal. However, learning
influences the emotional pattern considerably, which cannot be ignored.
6. Memory: Memory is the ability to retain and recall what is conceived. It is
the faculty for keeping things in one's mind. Memory therefore, is an essential
faculty of individuals, which is closely associated with perception and learning.
Though it can be an inborn quality considerable amount of memory power can be
achieved through recollection also. Individuals differ in their memory power which
is the ability to remember things after some interval. Though it is an essential
faculty, under certain circumstances ability to forget is also a blessing.
Interests, behaviours and approaches, motivation, and such other factors also
differ considerably from individual to individual. Accordingly, individual behaviour
may also differ.
Model of human being
The self, or human nature, interacts with world through "connectedness" this
is the continuity between internal psycostructure and external objects. To
understand the behaviour of people which is a very complex thing, there is need to
examine the structural integrative and field properties of a human system. Let us
128
make an attempt to broaden our perspective of man's nature by analysing and
understanding the major models of a human being.
Psychoanalytic Model of a Man: It is based on the pioneer work of Sigmund
Freud. The underlying principle of this model is based on the clinical analysis. This
model is complied and outlines three sets of concepts (id, ego and super ego) and
their interaction. The behaviour is the result of interaction of three key sub-systems
within the personality, 'id' 'ego' and superego’. The 'id' contains the innate drive of
man such as hunger, thirst and aggression. These innate drives are constructive,
primitive and sexual in nature which provides the basic energy of life. The ' id'
operates as pleasure seeking principle and is concerned with immediate pleasure. It
is there selfish and unconcerned with reality or moral considerations. The second
sub-system the 'ego' develops to mediate between the demands of the ‘id’ and the
realities of life. The initial concept of 'ego' was that it is meet the 'id' demands. But
‘ego’ in fact is the central control of personality and operates in terms of reality. The
third key system the ‘superego’ which contemplates moral values of society, it is the
conscience which is concerned bad, right or wrong. Superego is the additional inner
control coming into central operation to cope with the uninhibited desire of the 'id'.
Anxiety
Anxiety is both a painful experience and a warning of impending danger and
hence forces the individuals to do something to adjust with the situation. Ego can
cope with anxiety by rational measures. Freud distinguished three types of anxiety
(a) Reality anxiety (b) Neurotic anxiety (c) Moral anxiety. The reality anxiety stems
from threats in external environment. The neurotic anxiety arises when 'id' is
threatened to break ego control and the resulting behaviour will lead to
punishment. The moral anxiety when individual contemplates doing something.
Another point of importance in psychoanalytic model of man is the psychosexual
development. Freud said psychosexual development as a succession stages
characterised to achieve libidinal pleasure. Following stages of psychoanalytic
formulation.
Oral stage: This occurs during the first year of life when libidinal pleasure is
achieved primarily through stimulation of the lips and mouth
Anal Stage: It involves the second and third year of life in which the libidinal
pleasure is associated with defecation.
Phallic Stage: The stage of “Phallic” is between 3 and 5 years ago when the
child seeks pleasure through self manipulation of the genitals.
Latency Stage: The stage of "Latency" is between 6 and 12 years ago when
sexual pleasure recedes in importance and the child is busy in developing various
skills.
Genital Stage: The final stage is the genital stage in which real pleasure
comes from heterosexual relations. Thus psychoanalytic man is dominated by
instinctual biological drives an unconscious motives.
129
Behaviouristic Model of Man: The concept of behaviour stems from the early
work of John Watson. He emphasised that through the objective observation of
behaviour and stimulus conditions, the psychologists learn to predict and control
man's behaviour. The behaviourists make a distinction between respondent and
apparent behaviours. The respondent responses include simple reflexes and
emotional responses which are elicited by appropriate stimuli even prior to
learning. The term apparent is brought in because in such responses the individual
operates upon or modifies the environment. Crucial to both respondent and
apparent condition is reinforcement which refers to the strengthening of the new
responses by presentation of suitable stimulus.
Reinforcement may be negative as well as positive. Reinforcement is effective
because it reduces the level of tension created by biological drives like hunger and
other physiological needs (primary drive) and psychological needs like social drives,
self- esteem, social approval (secondary needs) etc. learned condi tioning. Similarly
generalisation is the tendency for a response developed by a conditioned stimulus
to become associated with other stimulus. Similarly discrimination occurs when the
individual learns to distinguish between similar stimuli and respond to one and not
to another. According to this model complex processes such as perceiving, forming
concepts, solving problems, taking decisions etc. are based on the core idea of
discrimination operation.
Humanistic Model of Man: Humanistic model attributes great importance to
human learning but emphasises reflection, reasoning and creative imagination
rather than conditioning. Much of human behaviour is influenced by past
experience. The human being is self aware, future oriented and capable of resisting
environmental influences. The idea of self is somewhat synonymous with the of ego.
The humanistic model emphasises the concept of uniqueness of individuals,
recognition actualisation.

LESSON - 14
MOTIVATION AND PERSONALITY
14.1. INTRODUCTION
Motivation describes the forces acting on or within a individual that cause the
individual to behave in a specific and goal directed manner. Motivation is the most
important concept in understanding the behaviour of the individual. Every
organisation has people with-outstanding abilities who perform better than the
others. Why do some people perform well while others do not? We try to answer the
questions by understanding the meaning of the motivation.
People in the organisation have dignity, self-respect, values, sentiments and
aspirations apart from the economic status. Because of these the efficiency of the
enterprise is related not only to the efficiency of the sophisticated machines
installed but also importantly upon the satisfaction and desire of people to put their
mind and heart into the work.

14.3.1. MEANING
Motivation encompasses numerous complex aspects of human behaviour to
which contribution has been made by Sociologists, Social Anthropologists,
Psychologists and the business executives.
The term motivation was generated from the Latin word 'movere' which means
'to move'. People who are 'motivated' exert greater efforts to perform than those who
are not motivated. However, this definition is relative. Berelson and Steiner (1964)
defined 'A motive is an inner statement energies, activities or moves, and that
directs or channels behaviour towards goals'. Sanford and Wrightsman (1970)
described that a motive is a restless-ness, a lakh, a yen, a force, once in the group
of motive, the organism does something. It most generally does something to reduce
restlessness, to remedy the lakh, to alleviate the yen, to mitigate the force; a more
descriptive and less substantive definition would say that motivation is the
willingness to do. Willingness to do is conditioned by the need for satisfaction.
"Motivation refers to the way in which urges, drives, desires, aspirations, strivings
or needs, direct, control or explain the behaviour of human beings" (DALTON).
132
The definition of motivation includes the following:
The urges, drives, desires, aspirations, strivings or needs of a human being
influence human behaviour,
The factors to influence human behaviour are Psychological sociological,
economical or managerial.
The efficiency of such behaviour - this may be tested by the resultant action.
Whether this behaviour has directed, controlled or implemented the desired action.
If the individual feels motivated, his behaviour will result in the performance of
desired action. Volumes have been written on human motivation, the two
outstanding works of Abraham Maslow and Frederick Herzberg may be considered.
To be the pillar posts on this subject Professor A.H. Maslow wrote motivation and
personality and Professor Frederick Herzberg, Bermard Mausener and Barbara
Block Synderman wrote books on motivation to work. The word 'motive' has been
interpreted the many words like 'desires', 'counts', 'wishes', 'aims', 'goals', 'needs',
drives' and 'incentives'.
Motivation process
The motivation process is depicted in the following figures:
Figure – I
Figure – II
Motivation of people depends on their motives. Motives are defined more often
as needs, wants, drives or impulses within the individual. Motives are generally
directed towards goals. These goals may be conscious or sub conscious.
An unsatisfied need creates tension which stimulates drives within individual.
The drives generate a search behaviour to find a particular goal that, if attained,
will satisfy need and lead to reduction of tension, Motivated employees are in a
state of tension. In order to relieve this tension, they engage in activity. The greater
the tension, the more activity will be needed to bring about relief. When individuals
work hard at some activity, we can conclude that they are driven by a desire to
achieve some goals that they perceive as having value to them.
It is, however, underivable that motives are directed to the attainment of goal
which in turn determine the behaviour of the human beings. This behaviour
ultimately leads to goal directed activity' such as preparing food and goal activity
such as eating food (Hersey & Kenneth). The motivation process is built on the
foundation of unsatisfied need. Although infrequently viewed as self-serving
desires, human beings behave in a way that they perceive to be best in their se lf
interest. Ever, consciously or unconsciously asks, himself, what is in kit form of
engaging in any form of behaviour. The principle that individuals are motivated by
their self interest underlies almost every economic theory and is contained,
133
explicitly or implicitly in all theories of motivation. Whether it is called self serving
behaviour, need satisfaction or whatever, the underlying concept is the same:
individuals act so as to maximise their own self interest. Thus, self interest is the
ultimate motivating process.
In systems sense motivation consists of three interacting and independent
elements, motives, behaviour and goals.
Behaviour
All behaviour is a series of activities. Behaviour is generally motivated by a
desire to achieve a goal. At any moment individuals may indulge in multifarious
activities like working, talking, eating and the like. They switch over from one
activity to another activity quickly. In order to predict and control the behaviour
managers must understand the motives people.
Motives (needs)
The terms motives, needs and drives are used interchangeably Motives are
action-oriented and provide thrust toward goals accomplishment. Needs are created
whenever there is a physiological or psychological imbalance. For example, the
needs for food and water are translated into the hunger and thirst drives, and the
need for friends becomes a drive for affiliation.
Goals
Motives are directed towards goals. Motives generally create a state of
disequilibrium, physiological or psychological imbalance within the individual.
Attaining a goal will tend to restore physiological or psychological balance. Goals
are the ends which provide satisfaction human wants.
Types of needs - primary needs (Motives)
Psychologists classified needs into different categories. A simple classification
is primary needs and secondary needs. The primary needs include physiological
needs. Physiological needs are food, shelter, clothing, water, air etc. These needs
arise from the basic physiology of life and are important to survival and
preservation. Therefore, these needs universal in people but the intensity of these
needs may vary from person to person. These physiological needs are conditioned
by social, pu.1et.1ces and are physiologically based. The primary motives include
hunger, thirst, sleep and material concern.
General Motives
General Motives are those which lie between the primary and secondary
motives. The motives of competence, curiosity, manipulation, activity and affection
can be included in this category. An understanding if these motives is important to
the study of human behaviour. They are relevant to organizational behaviour than
the primary motives.
The competence motive
Robert White (1959) built his tie of motivation around competence. He believes
that people strive to have control over their competence. This motive is mostly
134
exhibited at the age of nine by venturing out into the world on their own by
crossing the road by themselves, ride a bicycle, play basket ball etc. These needs
are manifested by the drive for competence, or mastery over the environment.
This motive has interesting implications for job design in an organization.
People may be motivated by the challenging job of trying to master the job or to
become competent in the job.
The curiosity manipulation and activity motives
Although these drives often get the small child into trouble, curiosity
manipulation and activity, if carried forward to adulthood can be very beneficial to
the organisation. If the employees are stifled from expressing curiosity,
manipulation and activity motives the organisation will eventually suffer.
The affection motive
Affection Motive is associated with both primary and secondary motives.
Affection motive is associated with love and affiliation. Affection deserves special
attention because of its growing importance to the world where we suffer from
interpersonal, inter-individual and national conflict where quality of life and human
rights are becoming increasingly important to modern society.
Secondary motives
The Secondary drives are undoubtedly critical to the study of the human
behaviour. As a human society develops economically and becomes more complex,
the primary drives and to a lesser degree, the general drives give way to the learned
secondary drives in motivating behaviour. Secondary needs vary among people
much more than primary needs. This exists even as opposites in two different
persons. One person has a need for self assertion and is aggressive with people. A
second person on the other hand may be submissive and to yield to others
aggressions. Needs also change according to the situation. Secondary needs
produce a variety of motives in each person. For example, the behaviour-
absenteeism can result from lack of interest in the job conflict with a co-worker or
for a variety of other reasons.
Characteristics of secondary needs
Secondary needs are often hidden, so that a person cannot recognize them.
This fact alone makes motivation difficult. Since secondary needs are so vague,
dissatisfied workers often say their dissatisfaction is caused by something easier to
identify, such as low wages. In summary, secondary needs are strongly conditioned
by experience. They vary in type and intensity among people. They are subject to
change within an individual work in groups rather than alone. They are often
hidden from conscious recognition. They are vague feelings instead of specific
physical needs and influence behaviour.
Although human needs have been classified as Primary and secondary needs,
in an individual person, they are inseparable. The state of the physical body affects
the mind and the state of mind can affect the physical body. Everyone must be
treated as a whole person.
135
Need for power, need for achievement and need for affiliation are some of the
important secondary motives. They are commonly referred to as n Pow, n Ach and n Aff.
The power motive
McClelland has also done research on N. power. His latest work discusses the
two faces of power. McClelland (1976) differentiates between personal power and
institutional or social power. McClelland describes the institutional power manager
exercises power in the interests and the welfare of the organisation. Institutional
power managers are said to be very effective since they are wil ling to somewhat
sacrifice their own interests for the organisation's overall well being.
Clayton P. Alderfer (1911) explained the power need as the need to manipulate
others or the drive for superiority over others. Any one in a responsible position in
business, government, unions, education or the military may exhibit a considerable
need for power. Power motive has significant implications for organizational
leadership and for the informal, political aspects of organization, power has
emerged as the one of the most important dynamics in the study of organizational
behaviour
The achievement motive
David Mc Clelland (1961) used the Thematic Apperception Test (TAT) which
proved to be very effective tool in researching achievement. One picture in the TAT
shows a young man ploughing a field, the sun is about to sink in the west. The
person supposed to take the test is suppose to tell a story about what he or she
sees in the picture. The story will project a person's major motives. For example,
the test taker may say that will the picture is sorry the sun is going down because
he still has more land to plough and he wants to get the crops planted before it
rains. Such response indicates high achievement. A low achiever might say that.
the man in happy the sun is finally going down so that he can go to the house relax
and have a cool drink.
Individuals high in N. Ach exhibit certain characteristics and can easily be
spotted in organization. High N. Ach individuals like to work on jobs which are
fairly challenging. Too little challenge will bore them, since there is no opportunity
to satisfy their urge to achieve. High N. Ach individuals will not try to work on jobs
that are so challenging that successful task accomplishment becomes doubtful.
High N. Ach individuals hence seek jobs that are so challenging that successful
task accomplishment becomes doubtful. High N. Ach individuals hence seek jobs
that are moderately challenging. The achievement motive can be expressed as a
desire to perform interims of a standard of excellence or to be successful in
competitive situations. The specific characteristics of a high achiever can be
summarised as follows.
The affiliation motive
Affiliation plays a very complex but vital role in human behaviour. Individuals
high in N. Affiliation (N.Aff) like to interact with colleagues in the organisation. They
have a strong desire for approval and reassurance from others and they are willing
136
to conform to the norms of groups to which they belong. In effect, they have needs
to develop affinity and warm relationships with people in the work system. They
usually like to work with others in a friendly atmosphere.
Sometimes affiliation is equated with social motives and or group dynamics.
When we go back to the Hawthorne studies conducted many years ago, the
importance of affiliation motive in the behaviour of organizational participants is
very clear. Employees have a very intense need to belong to and be accepted by the
group. This affiliation motive is an important part of the group dynamics. People
high in N. Affiliations are said to perform better in their jobs when they are given
supportive feedback. Co-operative work norms where pressure for increased output
comes from friends also increase outputs. Thus friendly managers and supervisors
can influence individuals high in N. Affiliation and motivate them to work harder.
The security motive
Security is a very intense motive. Security motive appears to be very much
simpler. Humans have learned security motive to protect themselves from the
contingencies of life and actively try to avoid situations which would prevent them
from satisfying their primary, general and secondary motives. The simple conscious
security motive is typically taken care of by insurance policies, personal savings
plans, and other fringe benefits at the place of employment. On the other hand the
more complex, unconscious security motive is not so easily fulfilled but may have a
greater and more intense impact on human behaviour.
The status motive
Status or prestige is more relevant along with security in today's dynamic
society. The modern affluent person is often painted as a status seeker and is
accused of being concerned with material symbols of status like the right clothes,
the right car, or the latest personal computer than the more basic, human oriented
values in life. Status can be simply defined as the relative ranking that a person
holds in a group, organization or society. Everyone has status, but it may be high
or low depending on how the relative positions are ranked. Sociologist Talcott
Parson, identified the membership in a family, personal qualities, achievements and
authority and power possession are the sources of status.
14.3.2. THEORIES OF MOTIVATION
Theories of motivation can be categorized broadly under content or need theories,
cognitive or process theories. Maslow, Alderfer, Murray. McClelland are some of the
people who have made significant contribution to the content theories which basically look
at the motives or needs in individuals that influence behaviour.
The content theories of work motivation
The content theories of motivation which are basically concerned with the need
patterns of the individuals are given below.
The content theories of work motivation attempt to determine what is that
motivates people at work. The contents theorists are concerned with identifying the
137
needs/drives that people have and how these needs/drives prioritised. At first,
money was felt to be the only incentive (scientific management) and then a little
later it was felt that incentives include working conditions, security and perhaps a
democratic style of supervision (human relations).
Recently the content of motivation has been deemed to be the so called 'higher-
level' needs or motives, such as esteem and self actualization (Maslow),
responsibility, recognition, achievement and advancement (Herzberg) and growth
and personal development (Alderfer) A thorough understanding of work motivation
leads to specific application techniques.
Maslow’s hierarchy of needs
Abraham Maslow (1954, 1968) need hierarchy theory is probably the most
widely known theory of individual needs and motivation. Abraham Maslow
recognizes that needs have a certain priority. As the more basic needs are satisfied,
a person seeks to fulfil the higher-level needs. If one's basic needs are not met, they
claim priority, and efforts to satisfy the higher-level needs must be postponed. A
need hierarchy of five levels of AH Maslow has gained wide attention. He has
synthesised these problems and postulated a need hierarchy, while suggesting that
a need if fulfilled easily will not be motivation. The five levels include
1. Physiological needs
2. Safety and Security needs
3. Belonging and Social needs
4. Esteem and status needs
5. Self actualization and fulfilment needs
The important point about need levels is that they usually have a definite
sequence of domination. Second-level needs do not dominate until first-level needs
are reasonably satisfied. Third level needs do not dominate until first and second
level needs have been reasonably achieved and so on. as illustrated in the Figure -3.
Maslow’s Hierarchy of needs
138
Lower order needs
People must labour to satisfy their physiological needs. These needs comprise
food, clothing, shelter, sex, etc. When these are satisfied to some degree, it becomes
their wish to satisfy other needs.
The need that next tends to dominate is for safety and status. Having satisfied
their basic physiological needs today, people wants on assurance that these needs
will be met tomorrow and thereafter. Because of individual differences, people need
different amounts of security. These needs are also called as economic needs.
Higher order needs
Third level needs are belonging and social involvement. Some people say that
these needs are met mostly off the job. However, one third-to one-half of an
employee's working hours are spent at work. People work in a social environment,
and some of their social needs must be met there as well as away from work.
Emotional needs for affection, love, warmth and friendship are satisfied by
being in the company of friends, relatives, or other groups such as work groups,
play groups and voluntary groups.
The needs at fourth level include those for esteem and status. We need to feel
made ourselves that we are worthy, to feel also that others think we are worthy,
(status) and to believe that they likewise are worthy. The ease of self worth and ego
can be satisfied with respect, recognition, esteem, appreciation and applause from
others. The fifth level need is that for self actualization, which means becoming all
one is capable of becoming. This need is less apparent than others because many
people in the developing countries are busy wi th first, second level needs and the
people in the developed nations are busy with third and fourth level needs. Though
self actualization dominates few people, it influences nearly all people. They choose
occupations that they like and they get certain satisfaction from accomplishing
their tasks.
Hierarchy of needs - an interpretation
Maslow suggested that there are five Levels of needs arranged in hierarchical
fashion. Maslow further suggested that all satisfied need is not a motivator. He
contended that on unsatisfied need motivates a person.
Lower needs are primarily satisfied through economic rewards. People earn
money as a medium of exchange to purchase satisfaction for physiological and
security needs. Their higher order needs are primarily satisfied through
psychological and social rewards. These higher needs require different ways of
thinking about people. Managers have felt sometime that wages i.e. money solves
everything.
The five-way classification of needs is somewhat artificial, because individual
difference causes many expectations to it. In a real situation all needs are
interacting together within a whole person. They try to overlap and combine.
139
However, the five way classification does give managers useful insights into which
needs are likely to dominate a person in a specific situation.
The concept of hierarchical needs may be helpful to the management to design
a motivational model which includes the level of priorities attached by the worker
for the fulfilment of his needs. Individuals will certainly like to fulfil the first
category needs before switching to the second category needs. Every individual
would like to fulfil the needs falling in the first two categories. The remaining needs,
highly situational, are influenced by the society, culture and individual's own
characteristics.
What the need hierarchy model essentially says is that gratified needs are not
as strongly motivating as unmet needs. That is employees are more enthusiastically
motivated by what they are seeking than by what they already have. In other terms,
people work for food alone when they have no food i.e., satisfied need is not a
motivator or an unsatisfied need is a motivator. Managers who understand the
need pattern of their people can provide the types of work environment that will
satisfy their needs at work. Managers can motivate employees by giving appropriate
organizational support which will gratify individuals needs. Maslow's theory helps
managers in understanding the needs of individuals and motivate them.
Herzberg's two-factor theory of motivation
Herzberg developed a specific content theory of the work motivation which is
an extension of Maslow's need theory. Herzberg's research concluded that job
satisfiers are related to job content and that job dissatisfies are related to job
context. Herzberg titled satisfiers as motivators, and the dissatisfies as hygiene
factors. Hence, it is known as the Herzberg's two factor theory of motivation.
Hygiene factors
Company policies and administration, supervision, working conditions, inter
personal relations, money, status and security may be thought of as maintenance
factors. These are not an intrinsic part of the job, but they are related to the
condition under which a job is performed. Herzberg found that Hygiene factors
produced no growth in worker output capacity.
Motivators
Satisfying factors that involve feelings of achievement, professional growth and
recognition that one can experience in a job of less challenge and scope are referred
to as motivators, Herzberg used this term because these factors seem capable of
having a positive effect on job satisfaction.
Herzberg's (1966) theory is closely related to the Maslow's need hierarchy. The
hygiene factors are similar to the Maslow's lower order needs (see Fig. 3). The
hygiene factors are preventive and environmental in nature. These hygiene factors
prevent dissatisfaction, but they do not lead to satisfaction.
The hygiene factors do not motivate but they prevent the development of
dissatisfaction. Motivators will motivate on the job. Maslow's higher order needs
140
and motivators are approximately the same. According to Herzberg an individual
may be motivated with a challenging job content. Herzberg's two factor theory has
thrown light on the content of work motivation. Management are often perplexed
because they are paying high wages and salaries, giving excellent fringe benefit
package and provide best working conditions, but their employees are not still
motivated. Most of the management concentrate on hygiene factors. Whenever they
face the problem of morale, they give higher pay, more fringe benefits and better
working conditions. Herzberg's theory offers an explanation by stating that
management are concentrating on hygiene factors rather than on motivators.
Herzberg identified certain characteristics with job satisfaction and others to job
dissatisfaction. Intrinsic factors such as achievement, recognition and the work
itself, responsibility and advancement seem to be related to job dissatisfaction. On
the other hand when they were dissatisfied, they cite extrinsic motivators, such as
company policy and administration, supervision, inter personal relations, and
working conditions.
According to Herzberg, the factors leading to job satisfaction are separate and
distinct from those that lead to job dissatisfaction. Therefore, managers who seek to
eliminate these factors that can create job dissatisfaction can remove
dissatisfaction but not necessary motivation. When the Hygiene factors are
adequate, people will not be dissatisfied. If we want to motivate people, Herzberg,
suggests using achievement recognition, the work itself, responsibility and growth.
These are the characteristics that people find intrinsically rewarding. Herzberg was
the first to say that the hygiene factors are absolutely necessary to maintain the
human resources of an organisation. According to Herzberg's theory only a
challenging job which has the opportunities for achievement, recognition,
responsibility, advancement and growth will motivate personnel. The theory has
been criticized for the following weaknesses.
1. Herzberg's theory over simplified the work motivation.
2. The Reliability of the methodology is questioned.
3. A person may dislike part of his or her job, yet still think the job is acceptable.
4. The motivation - hygiene theory ignores situational variable.
5. Herzberg assumes that there is a relationship between satisfaction and
productivity. But the research methodology he used looked only at satisfaction
but not productivity.
Inspire of the limitations Herzberg contributed substantially to the study of
work on motivation. Herzberg also drew attention to the importance of job content
in work motivation which has been neglected or totally overlooked. The job design
technique of job enrichment is-also one of Herzberg's contributions. Overall,
Herzberg also failed to give a Comprehensive theory of work motivation. It also
partially describes the complex nature of motivational process of people in the
organisation.
141
14.3.3. PERSONALITY
Behaviour always involves a complex interaction of the individual and the
situation. When are some people quiet and passive, while others are loud and
aggressive? or certain personality types better adopted to certain Job types? What
do we know from theories of personality that can be help us to explain and predict
the behaviour of individuals in organizations? This section, to answer such
questions.
What is personality?
When we talk of personality, we do not mean that a person has charm,
attitude toward life. When psychologist talk of personality, the dynamic concept
describing the growth and development of a fair psychological system rather than
looking at part of the person, personality looks at some aggregate whole that is
greater than the parts. A human personality is determined by four very closely
interconnected aspects.
1. Moral qualities which are the social aspect of the personality.
2. Temperament which is the biological basis of the personality
3. Individual characteristics of the psychic process; sensations, perceptions,
attention, thinking, memory, emotion, etc.,
4. Schooling - the persons knowledge and skills.
The term personality' is derived from the Latin word 'per sonnare" as to speak
through". The Latin term was used to denote the actors used to wear in ancient
Rome and Greece. Personality totally referred to how people influence others
through their appearances (actions). But for an academician personality external
appearance and behaviour, (ii) the inner awareness of permanent organizing force
and (iii) the particular organization of measurable traits, both inner and outer.
Thus, a thoroughly complete definition of personality becomes a jigsaw puzzle
because human being operates as a whole, not as a series of distinct parts. Though
psychologist scientists unanimously agree to the importance of personality, able to
come out with an unanimous definition. Personality has various views by many
people in different ways as found below
Personality is a broad, amorphous designation relating to all approaches of
persons to others and themselves. To most its and students of behaviour, this term
refers to the study of the characteristic traits of the individual, relationships
between these ' the way in which a person adjusts to other people and situations.
Personality is a pattern of stable states and characteristics of a person, that
influence his or her behaviour towards goal achievement. Each person has unique
ways of projecting these states.
Personality is a very diverse and complex psychological concept. The word
'personality' may mean something like outstanding, invigorating interpersonal
abilities.
142
We must also recognize and explain the fact that development results in man
by acquiring a distinctiveness or uniqueness which gives him identity which
enables him and us to recognize him as apart from others. These distinguishing
characteristics are summarized by the term personality.
The most frequently used definition of personality was by GORDON ALLPORT
more than fifty years ago. He said personality is "the dynamic organisation within
the individual of those psycho physical system that determines his unique
adjustments to his environments. Hence, personality is the sum total of ways in
which an individual reacts and interacts with others. A person's moral qualities are
the most important traits of personality, that dominates over all its other traits and
determines his behaviour. These qualities largely depend on the persons outlook,
his views and conceptions of the surrounding world and natural and social
phenomena. So personality is a combination of body and mind. Personality is
neither exclusively mental nor exclusively physical but it is a function of mind and
body in unity. It is an universal phenomena found in individual
Personality Attributes
Four personality attributes have been identified that appear to have more
direct relevance for explaining and predicting behaviour in organizations. These are
1. Locus of control
2. Authoritarianism
3. Machiavellianism
4. Risk propensity
1. Locus of Control: Some people believe that they are masters of their own
fate. Other people see themselves as pawns of fate, believing that what happens to
them in their lives is due to luck or chance. Locus of control is internal; these
people believe they control their destiny. Those who see their life controlled by
outsiders are externals. The employees who rate high in externality are less
satisfied with their jobs. More alienated from the work setting and less involved in
their jobs are internals. A manager might also expect of find that externals blame a
poor performance: evaluation on their boss's prejudice their own other events
outside their control. Internals would probably explain the same evaluation in
terms of their own actions
(2). Authoritarianism: It is the belief that there should be status and power
differences among people in organizations. The extremely high authoritarian
personality is intellectually rigid in judging of others. They are differential to those
above and exploitative of those below, distrustful and resistant to change.
Possessing a high authoritarian demands sensitivity to the feelings of others, tact
and the ability to adapt to complex and changing situations. On the other hand,
where jobs are highly structured and success depends on close conformity to rules
and regulations, the high authoritarian employee should perform quite well.
143
(3) Machiavellianism: It is named after NICCOLO MACHIVELLI who wrote in The
16th century on how to gain and manipulate power. An individual executing strong
Machiavellian tendencies is pragmatic, maintains distance and believes that ends
can justify means. Do high machs make good employees? That answer depends on
the type of job and whether you consider ethical implications in evaluating
performance. In jobs that quite bargaining skills (such as labour negotiator) or
where there are rewards for winning (as in commission sales) high machs may be
productive. The ends cannot justify the means or there are no ability standards of
performance, our ability to predict a high machs perform will severally be reduced.
(4) Risk Propensity: People differ in their willingness to take chances.
Individuals with a high risk propensities make more rapid decisions and less
information in making their choice than low risk propensity individuals. Managers
might use this information to align employee risk tasking propensity with specific
job demands.
Stages of Personality Development: Personality development as by Floyed L.
Ruch is concerned with "the process by which the child gradually acquires patterns
of overt behaviour, thinking, problem-solving and, above all, the motives, emotions,
conflicts and the ways of coping up conflicts that will go to make up his adult
personality". The development approach, though a form of personality theory, is
different from personality theories which will be discussed separately.
Personality in modern times is consisting of both elements-physiological which
interact to result in desirable action by an individual. 'Hence, it is needless to argue
heredity versus environment or motivation versus learning. In fact, all these
variables, heredity, environment, or motivation and learning- contribute to the
development of human personality. A personality variable usually processes three
characteristics; (i) ability over time, (ii) generality across situation and (iii) interim]
variability in either frequency of occurrence or intensity.
The stages of personality development may be identified as follows.
(1) Psycho-analytical or Freudian stage
(2) Social learning or Neo-Freudian stage
(3) Cognitive stage.
Psycho-analytical or Freudian Stage: Psycho-analytical theory propounded
by Sigmund Freud in 1932 concentrates largely on five identifiable stages of
psycho-sexual development through which a child passes. These stages are (i) Oral,
(ii) anal, (iii) phallic or Oedipus, (iv) latency and (v) genital. These stages are
explained earlier.
Though these stages did lead to the acquisition of particular motives such as
sexuality, hostility, dependency, etc. they have not been accepted by modern
psychologists on two grounds: (i) improper use of terminology and (ii) stretching the
stages to the degree of illogical ends. Regarding choice of words Mischel makes the
following observations:
144
"Without having at hand a suitable set of learning concepts and terms for
personality development, Freud relied on his own preference for a 'body language',
he preferred to say 'oral' rather than 'dependent', 'anal' rather than 'compulsive',
'genital' rather than 'mature'.
The other shortcoming in his philosophy was his over-emphasis or sex which
overshadowed the underlying concepts which he intended to project.
Neo-freudian Stage: Julian Rotter in 1954 and Albert Bandura in 1962 laid
greater emphasis on social learning theory to acquire motive values, expectancies
and behaviours through social reward and punishment. Erik Erikson in 1962 also
highlighted the need for social rather than sexual adaptation of an individual.
Erik Erikson has identified eight psycho-social stages of development. They are
stages, (1) Mouth and senses (2) Eliminative organs and musculature, (3)
Locomotion and genitals, (4) Latency develop during birth to sixth year of age. The
remaining stages (5) Puberty and adolescence (6) Early adulthood (7) Young and
middle adulthood and (8) Mature adulthood develop later.
Erikson thought it strongly that psycho-social crisis occurs within each of the
above stages; to have a normal fulfilling personality, it is necessary that each crisis
should be resolved optimally. Most vulnerable crisis is associated with the stage of
adolescence which provides a point of criticality to re-integrate the past with future
goals. However, from organizational behaviour point of view, it is the young and
middle adult stage which is most important. Most organizational participants are
found in this stage which are seen struggling between "generatively" and
"stagnation". Young and middle-aged adults may overcome their crisis by being
productive to organization which will ultimately result in the development of their
healthiest personalities. It enjoins on the organizations to take benefit of this
productivity drive implemented by the adults.
Cognitive Stage: The cognitive stage of personality development breaks
further apart from the Freud's psycho-analytical theory. The most Representative
work on cognitive theory is of Swiss psychologist Jean Piaget. Unlike Freud, Piaget
was convinced that it was conscious and not the instinctive unconscious was the
most important variable in the development of individual's personality. He is also
accredited as the forerunner in the development of child psychology. Earlier
psychologists did not consider child as their subject, of research. He felt that
learning consists of an important accompaniment of development which cannot
crystallise unless the child has the necessary cognitive structure to assimilate new
information. This was a new challenge to the behaviourists. He identified four major
stages of cognitive (intellectual) development: They are (1) Sensorimotor (0-2 years)
(2) Pre-operational (2-7 years), (3) Concrete operational (7-11), (4) Formal
operational (11 and above years).
In the earliest stage, "Children acquire knowledge or cognition about their
surroundings through simple, sensorimotor manipulations". During this stage
when the child is of few months, he repeats acts which bring him reward or some
145
interesting outcome. After reaching the age of about two years, he starts solving
simple problems. He also realises that there are objects in the world separate from
themselves which they can affect or control to get the desired results. It is the stage
when shift takes place from sensorimotor to conceptual or operational level. During
the per-operational stage children begin to use symbols and language in their
thought process so as to develop a class or category.
He enters the concrete stage of cognitive development. It is at this age that he
understands concepts such as conservation which may best explained by the
following example given by Fred Luthans:
“Water is first poured into two identical containers. Children in either pre-
operational stages will readily acknowledge that the two containers contain equal
amount of water. Then the water in one of the flat containers is poured into a tall
container in front of the child. When asked which container has more water,
children in the pre-operational stage will generally say tall container, but children
who are in the concrete stage will say that there is the same amount of water in
both the flat and tall containers".
The above example shows that only on reaching the concrete stage of
development the children may understand concepts such as conservation.
Piaget's empirical researches have revealed that certain social and political
attitudes depend on the stage of cognitive development. These results are of
immense relevance to the study of organizational behaviour.
The formal operational stage is reached by the mature and intelligent adults
who function in an organization. At this stage, there is no need for the
manipulation of objects. They have the needed capacity and skills to analyse,
reason, imagine and evaluate events.
It may, however, be stated that the four stages of cognitive development cannot
be equated with the personality stages in the same manner as Freud's psycho-
sexual stages. Both theories contribute partially to understanding human
personality.
Chris Argyris continuum from immaturity to maturity
Chris Argyris feels that the personality instead of passing through precise
stages develops along a continuum "from immaturity as an infant to maturity as an
adult".
He has identified seven characteristics in the immaturity- maturity continuum
in the following table.
Immaturity-Maturity Continuum
Immaturity Characteristics Maturity Characteristics
Positivity Activity
Dependence Independence
Few ways of behaving Diverse behaviour
146
Immaturity Characteristics Maturity Characteristics
Shallow interests Deep interests
Short-time perspective Long-term perspective
Subordinate position Superordinate position
Lack of self-awareness Self-awareness and control
He explains further the scope and the conditions under which his concept operates:
1. The seven dimensions represent only one aspect of the total personality. Much
also depends upon individual's perception, self-concept and adaptation and
adjustment.
2. The seven dimensions continually change in degree from the infant to the
adult end of the continuum.
3. The model, being only a construct, cannot predict specific behaviour. However,
it does provide a method of describing and measuring the growth of any
individual in the culture.
4. The seven dimensions are based upon latent characteristics the personality
which may be quite different from the observable behaviour.
He has made an assumption that the personality of a man in organization is
towards the mature end of the continuum. This will warrant a formal organization
to ensure activity for passivity, independence for dependence, long for short
perspective, superordinate to subordinate position and self- awareness and control,
to lack of awareness and perhaps external control.
Argyris feels that generally reverse happens with the result that the mature
organizational participant" becomes frustrated which results in conflict with the
organisation. In the light of this fact he rightly visualises incongruity the mature
man and the organization.
Probably Argyris has wrongly made a supposition that all organizational men
are mature. There are many persons even in private or governmental organizations
who, inspite of all aberrations in their personality, continue to function in the
organization. Their age and years of service have not bestowed any maturity and
commitment on them. This concept will vary if the basic assumption proves wrong
in the light of living examples in public and private enterprises in India and
elsewhere.
Personality Determinants
There has been an argument in personality research that whether an
individual's personality is the result of heredity or environment. Is the personality
predetermined at heredity in or is the result of individuals interacts with its
environment. However, personality appears to be a result of both influences. An
adult personality is generally considered to be made up of both hereditary and
environmental factors moderated by situational condition.
147
People are enormously complex; their abilities and interests and attitudes are
diverse. The drama of life unfolds in fantastically broad patterns from nursing
infant to the lonely senile adult; from the teens to the stable fifties; from the
idealistic to realistic; from tragedy of comedy; from the birth to death. The journey
of an individual through life can take infinite number of paths. But the question
arises I are the determinants of individual personality? We often notice personality
characteristics such as extroversion, assertiveness and warmth etc. greatly
contribute to success of an individual in his jobs. Most hires on job, however, are
not a tributable to a person's amount of intelligence alone but also to certain
personality characteristics. We frequently hear such comments as, "He is very
intelligent but lazy", "He is mediocre but hard-working" etc. The most pertinent and
relevant question is how personality originates and develops? The major
determinants personality of an individual can be studied under three broad -
headings-biological, environmental and situational.
Biological factors
Biological factors may be studied under three heads-the heredity, the brain the
physical stature.
1. Heredity: The relative effects of heredity comprises an extremely lament in
personality theory. Certain characteristics, primarily physical in nature, are
inherited from one's parents, transmitted by genes in the chromosomes contributed
by each parent. Research on animals has showed that both physical and
psychological characteristics can be transmitted through heredity. But research on
human beings is inadequate to support this viewpoint. However, psychologists and
geneticists have accepted to the fact that heredity plays an important role in one's
personality. The importance of heredity varies from one personality trait to another.
For instance, heredity is generally more important determining a person's
temperament than values and ideals.
2. Brain: Another biological factor that determines personality is the role of
brain of an individual. Though some promising inroads are made by researchers,
the psychologists are unable to prove empirically the contribution of human brain
in influencing personality. Preliminary results from the Electrical Stimulation of the
Brain (ESB) research gives indication that better understanding of human
personality and behaviour might come from the study of the brain.
3. Physical Features: Perhaps the most outstanding factor that contributes to
personality i.e. the physical stature of an individual. An individual's external
appearance is proved to be having a tremendous effect on his personality. For
instance, the fact, that a person is short or tall, fat or skinny, handsome or ugly,
black or fair will undoubtedly influence the person's effect on others and in turn,
will affect the self-concept. According to Paul H. Mussen a child's physical
characteristics may be related to his approach to the social environment, to the
expectancies of others, and to their reactions to him. These in turn may have
impacts on personality development. Similarly, a rapidly maturing girl or boy will be
148
exposed to different physical and social situations and activities than will a slowly
maturing boy or girl. Psychologists contend that the different rates of maturation
will also influence the individual's personality.
II. Environmental
Among the factors that exert pressures on our personality formation of the
culture in which we are raised, our early conditioning, the norms among our family,
friends and social groups and other influences that we experience. The environment
that we are exposed to plays a critical role in shaping a personality. Culture
established the norms, attitudes and values that are passed along from one
generation to the next and create consistencies over time. Heredity sets the
parameters or outer limits, but an individual’s full potential will be determined by
how well she adjust to the demands and requirements of environment.
III Situational
The situation influences the effects of heredity and environment on
personality. An individual personality changes in different situations. The different
demands of different situations call for different aspects of one's personality. Thus
situation will influence an individual personality.
Personality Traits: These are enduring characteristics that describe in
individuals behaviour. Popular characteristics include shy, aggressive, -
submissive, lazy, ambitions, loyal and timid.
16 Primary traits
1. Reserved Outgoing
2. Less intelligent More intelligent
3. Affected by feelings Emotionally stable
4. Submissive Dominant
5. Serious Happy go lucky
6. Expedient Conscientious
7. Timid Venturesome
8. Tough-minded Sensitive
9. Trusting Suspicious
10. Practical Imaginative
11. Forthright Shrewd
2. Self assured Apprehensive
13. Conservative Experimenting
14. Group dependent Self-sufficient
15. Uncontrolled Controlled
16. Relaxed Tense
Stages in personality development: The various stages of personality from
birth to maturity can be divided into following ten stages. Every individual passes
through these stages. They are:
(i). Stage of Dependence: Every individual starts his life completely
dependent on others. A few individual never weaned out from this dependence and
always lean on parents or friends or on someone.
149
(ii) Stage of Comfort and Eating: In this stage the chief interest is the
physical comfort and food. A few grow-up with a feeling that comfort is the most
important thing in life.
(iii) Stage of Impulsiveness: The parents praise the child when he takes his
first step, in the process of learning for walking by himself. But when he tries to
walk by himself on the street, his parents scold him. The child is unable to make
out the difference between the two activities and is in a stage of impulsiveness. He
is not able to understand the change from praise to punishment for walking. The
child acts first and thinks next, many adults who have outgrown childhood are

LEADER AND LEADERSHIP QUALITIES
15.1. INTRODUCTION
The role of the supervisor and his relationship with the worker are vital for an
effective functioning of any organization. Supervisors are a very important part of
management and this is because wider range of managerial responsibility falls on
the shoulders of the supervisors. The function and qualities of a supervisor is
linked with attitude, morale job satisfaction, industrial disputes and ultimately
production. The concept of leadership and the role of a leader or supervisor has
been changed, due to the growth of new social values. So Maier (1970) has
remarked “The supervisors become the pivotal around which many things revolve.
The type of personal contact which he builds can obviously make and break
morale”.
The supervisor of a fabricating plant remarked that his headaches were not
with the problem of production, but with the problem of supervision. Bass (1960)
has defined leadership as the observed effort of one member of change another,
member’s behaviour by altering the motivation of the other members or by
changing their habits.
Leadership is accomplishing something through other people what wouldn’t
have happened if you weren’t there. Today, leaders are being able to mobilise ideas
and values that energise other people.
15.2 OBJECTIVES

15.3.9 Training and Methods
According to Maier, the effectiveness of a leader is determined by whether
there is any change in the observed behaviour of the followers. This change is
induced by changing motivation and by initiating structure into the work situation.
The part played by leadership today in industrial relations is gaining importance
with increasing recognition. Blum and Naylor (1968) have said “Just as society
looks for a leader to define its purpose and lead it forward, so both management
152
and labour have been concerned in the selection and development of men who can
successfully attack the many perplexing problems that confront them”. Many
studies have shown that the supervisor who mostly determines the employee -
employer relationship is the centre and the crux around which the vari ed problems
of industrial psychology more.
15.3.1. Qualities of a Successful Supervisor
The congenial relationship between the employee and the employer mainly
depends upon the supervisor. It is absolutely essential for the supervisor to possess
certain qualities and characteristics in order to be successful in his role of
supervision. An employer has to maintain close contact with the workers. The main
problem is to lead, to guide and above all direct them. The employee -employer
relationship is not an unilateral affair but one of bilateral relationship. The problem
of maintaining sound interaction between the leader and the group has great
importance not merely in industry but in every field of activity.
It is rather difficult to give various criteria of successful leader. This is because
there is a variety of ways of defining the success of a leader. However, one
important criterion of determining good leadership is to find out, how far his
subordinates follow his order without question.
According to the behavioural approach the best way is to study what leaders
do, rather than in terms of what leaders are. So in this approach emphasis is
placed more upon the leader's behaviour rather than with the leader's traits.
Regarding leadership characteristics research findings show that the qualities of a
successful supervisor is behavioural or situational. In other words, it is related to
the interactions of the leader and the group. In short, a supervisor is not born, but
made. So the good qualities of a supervisor depend primarily upon the
environment. Further, it depends upon the situation at hand. Regarding the
personality factors, there is a wide variation in the qualities of a successful
leader/supervisor. For instance, a leader who is successful in an autocratic group
may not be so, in a democratic group.
In the words of Puckey, a leader must be able, to coordinate besides should
have the power to reflect the progress of the group. According to Dr. May Smith
(1952) a leader should have intelligence, insight and imagination, good judgement,
a sense of humour, a sense of justice and above all, a well balanced personality.
In fact, the overall personality of an individual is largely responsible for
determining leadership. In India, for example, besides other factors, the overall
personality of Mahatma Gandhi, Pandit Jawaharlal Nehru, Netaji Subhash
Chandra Bose, Shri Jaya Prakash Narayan, Mrs. Indira Gandhi and others, has
attracted many followers. And all of them are glittering examples of leaders who
possessed a great attraction for the people.
Some of the important qualities essential for a successful leader have been
mentioned by the Industrial Conference Board such as the ability to learn, to
analyse and gather new information, industriousness, resourcefulness and persis-
153
tency in attacking work problems, willingness to accept any criticism, emotional
stability and a sense of humour, the ability to inspire confidence, respect for other's
capacity for decision and ability to express oneself orally and so on.
According to Craig and Charters the necessary characteristics of a successful
leader are personal interest in employees, self-confidence, forcefulness, ability to
command and respect, ability to praise and blame effectively and so on.
Gibb (1922) has chalked out a list of seven aspects of leadership behaviour.
And they include performing professional and technical speciality, knowing
subordinates as well as showing consideration for them, getting channels of
communications open, accepting personal responsibility and setting an example,
initiating and directing action, training men as a team and making decisions.
A good leader possesses eleven qualities in the opinion of Kretch and
Crutchfield (1948), According to them, a good leader is a planner, an executive, a
gatekeeper, a mediator, an expert, a law maker, a father figure and so on. In the
words of Blum and Naylor (1968) a successful leader is a person "whose men
respect him, whose men follow his orders without question, whose men like him,
whose work group has high morale and who looks out for his men". In brief, the
leader should act as an ideal or an examples for the follower. Further he must be
capable of fulfilling the needs of the followers and by doing so he could win over the
confidence of his people.
15.3.2. Functions of a Supervisor
The foreman or supervisor today is something like a statesman according to
Tiffin. In other words, the foreman is both a commander and a helper to his
workers. In short, his personality and behaviour towards the workers determines to
a great extent the rate of production. By tracing the history of the supervisor, one
can note that a supervisor was all powerful. In fact, he was the monarch of all
hierarchies. He was rather interested in hiring and in firing the workers. The
supervisor was always considered right, while the workers were always considered
to be wrong. The supervisor in the past had to do a lot of work. For instance, he
was in charge of wage, rate of work, controlling the quality of work, method of work,
training the workers, maintenance of machinery, problems of discipline etc. All
these being his main functions, he was called a "jack of all trades but a master of
none". At that time, no consideration was given to the executive ability of the
supervisors. This was perhaps because, it was not needed at that period.
But in the modern period, drastic changes have taken place in the role of a
supervisor, especially with the development of scientific management and the
growth of new social values. Of late, the supervisor has become democratic and he
is no more a dictator. In the modern industrial development, the foreman's
responsibility has increased considerably. He is the representative of the
management to the workers. Further his role and position become very important,
since the average workers come into direct contact with him. Many of the old
functions of the supervisor have been changed and taken away such as the living of
154
the workers, maintaining discipline, lay off and strikes. And these functions have
been taken over by the personnel department. Similarly the Job evaluation
department has taken up task of fixing the rate of payment. Quality control is given
to a specialised technical department. Time and motion (movement) analysts
department are in charge of the rate or method of work. Maintenance and repair
work come under the custody of maintenance and repair department while training
programme is put under the control of tuning departments.
Although many of these duties have been taken from him, still the supervisor
has several other important duties. For example, the supervisor has to know a little
of law matters. The factories acts, wages acts, and contracts are handled by him.
Quick decisions are to be taken on account of the urgency of the matter. Disputes
are increasing as a result of the formation of several kinds of labour unions. In the
olden days, the supervisor was viewed always as right and the worker was found
always as wrong. But today, due to change in the status of the employees, both
groups are partly wrong and partly right. The supervisor has to tackle both the boss
and the worker. Sometimes in a critical situation, he has to handle several
conflicting orders with high degree of social skill. The technique of dealing will the
employees today has changed from an autocratic way to democratic one.
Understanding has become more important and suppose the supervisor is not
careful in all his dealings and transactions, he may breed hostility and
discontentment among the workers. In short supervisor is the pivotal around which
many problems revolve.
According to Brown (1958), "The supervisor is the conductor of an orchestra
rather than, a one-man band and he realises that his job is to coordinate and
creating willingness to work among employees".
On the psychological aspects, the supervisor-cum-employer has a terrific role
to play while dealing with employees. The employer works as a father-figure and the
employees depend upon him for emotional security, self-realisation and release of
tensions. So the supervisor should have the ability to take the workers into
confidence. At any stage, there should not be any type of sudden change, without
the knowledge of the workers. The employee must be in a position to predict, what
is expected of him. And as such the actions of his supervisors will be predictable.
Mild and consistent discipline by the employer must be encouraged instead of strict
and rigid discipline. It has been observed that leaders of several organisations who
are in the habit of showing their disapproval and dislike towards their employees in
the public, have been proved to be worst leaders. These leaders fail to understand
that each person has an ego and any insult would deeply hurt the person,
particularly when such damaging remarks are made in the presence of others or in
public. So, any criticism towards the employees should be expressed in private but
praise or appreciation can be made in public.
15.3.3. Types of Supervisors
Bardford and Lippitt (1946) have classified the supervisors into four types.
155
1. The hard boiled autocrat
2. The benevolent autocrat
3. The Laissez - faire supervisor
4. The democrat.
1) The Hard Boiled Autocrat
The hard boiled autocrat constantly checks production. He gives orders and
expects immediate acceptance. Mostly he is a rigid disciplinarian and he believes
that praise will spoil the workers' efficiency. He is very much status conscious. And
he does not trust the employee's initiative. Under such circumstances, the workers
criticise the leader at his back, which can be called as 'back-biting'. This kind of
behaviour makes the group to feel that he is insecure, tense, aggressive and
egocentric. But usually the Indian employees show an uncritical acceptance of
authority. According to Kakar (1971) the autocratic authority is the ideal image of
the Indian employees.
2) The Benevolent Autocrat
This is another type of leadership. A benevolent autocrat dominates all
employees. Suppose the employee fails to meet the standards, this makes him feel
hurt, angry and surprised in such a group, the employees depend upon the leader
for all decisions. Further these employees exhibit a slow regression to more
submission, dependency and inability to accept responsibility.
3) The Laissez-faire Supervisor
This type of leader often makes himself busy in paper work. And as such, he
tends to keep away from the employees. A leader of this kind has no goal and he is
indecisive. Such a group has the tendency of find out scapegoats. Further it is
unstable and it has low output. Finally, the laissez-faire group lacks direction. And
in such, a directionless group, failure and insecurity as well as frustration are
typical.
4) The Democrat
In this category the democratic supervisor shares group decisions. He spends
time for planning and he is quite decisive. He has high self-confidence and security.
He often encourages employees to function in a democratic framework as remarked
by Lippit and Bradford.
There are two major dimensions to the managerial grid, according to Blake and
Mounton (1964). That is to say, first there is concern for production and next there
is concern for people. And this two-fold categorization leads to five types of
managers.
1) The exacting task master is mainly concerned with production and least
bothered about human relations. In this type, the supervisor - subordinate
relationship is one of authority and obedience. 2) The second type is Worker -
Oriented Manager. He is highly concerned with human values and he is a
humanist. He helps the workers in their difficulties. He is not boss. And as such, he
156
gently persuades the employees to follow certain principles, without forcing them.
3) The third type is passive manager. He is neither concerned with production nor
with people (workers). He simply works formally as a manager by maintaining the
status quo. He has minimum involvement with the organisation. In short, somehow
he wants to manage and retain his position. 4) The fourth type is Complete
Manager. The basis of this manager is to promote the conditions which integrate
creativity, high productivity and high morale, through concerted team action. So he
is viewed as a complete manager who relies o mutual understanding. Adequate or
proper communication between the manager and staff is encouraged by the
complete manager. In other words, this type o manager believes in the bilateral
communication but not unilateral. 5) The final type is Individual - Organisational
Centered Manager. This type of Manager importance to optimum-coordination
between the needs of the workers and the requirements of the organisation. To him
the system of work should be designed and planned in such a way that both the
employees and the management achieve the best.
15.3.4. Selection of Supervisors
Supervisors were usually selected in the past, on the basis of the production
record. But this was not a desirable system. In the words of Gray (1952) "The
supervisor may understand how to control the machine, but not how to control his
men. Much of the time of the experts in industry is spent repairing damage to
human feelings by their supervisors, who do not know how to deal with their men.
While the supervisor is the master craftsman with material he is a novice with the
personnel". In other words, the supervisor takes care of the machine elements but
leaves the human elements untouched or unnoticed. So the selection of supervisors
has to be done from the humanitarian standpoint. And for the successful
supervisor, the production record is not that much important as the right attitude
and the right practice of this attitude of the employees.
According to Blum and Naylor (1968) in the selection: "several different types
of employees, psychological tests have been successful. But in the selection of
potential executives these tests have not been to any great help till now. A job
analysis of the qualities of a supervisor are quite essential for the selection of a
supervisor. So long as this has not been done, it is rather difficult to select a
supervisor. On the basis of tests and interviews supervisors may be selected.
However, the right method of selecting them has not yet bee i developed.
According to Kretch and Crutchfield (1948), the supervisor should know how
to behave and how to deal with the workers. Further, he should know how to apply
his potentiality in the right direction. In the word of Blun and Naylor (1998) by and
large, psychologists can effectively describe a person's characteristics, such as his
intelligence level, ambition level, maturity level, interests and abilities with the help
of psychological tests. Further by using these variables and their probable inter-
relations as his psychologists can provide descriptive evidence that will enable the
management to decide whether it wants such a person, for a specific executive
position. Suppose the criterion is known, the psychologist? Can do the matching!
157
But with regard to many executive positions, the trouble either the criterion, is
usually not clearly defined to perhaps the criterion varies from company to
company.
To sum up the successful qualities of a leader or supervisor can use developed
through proper training. In short, supervisors are made and they are not born. And
the qualities of a supervisor are situational and behavioural, suppose training is
given at all levels, a lot of inefficiency can be avoided. With the realisation of this
fact, the need for training all types of administrators has been well recognised and
put into practice.
15.3.5. Types of Leadership
“Leadership is the ability to persuade others to seek defined objectives
enthusiastically.”
Leadership can be classified into three categories or levels as given below, for
the purpose of management.
1. The big boss or the Top management.
2. The boss or the Middle management.
3. The Foreman and supervisors or Front line management.
The above mentioned three types of leaders function at different levels and
they have different duties and responsibilities. However, all the three categories are
concerned with the problem of how to deal with the employees and lead them. So, it
is essential to always keep contact with people. Thus, an effective and successful
leader is one who always tries to keep close contact with the workers or the
employees. According to Slum and Naylor (1968) that leadership is not an one way
affair. But it involves interaction of the leader and the group. From this stand point,
the first-line supervisor is considered as the leader or the supervisor for all practical
purposes. This is because he is the only person with whom the workers come into
immediate and direct contact for all practical purposes.
According to Barnard (1938) the job of an executive is responsible for devising
a system of communication, which will allow the organisation to function smoothly.
An executive should show a strong willingness to cooperate with people since he is
always concerned with securing services from individuals. In the words of Slum and
Naylor (1968) "The-executives formulate the general purposes of the organisation
and they must-indoctrinate their subordinates with these general purposes, so that
the organisation will function in a unified manner".
In an aircraft factory, Bose (1955) studied the importance of supervision on
productivity. High productivity was associated with employee centered supervision,
rather than close supervision and skill in supervising the group as a whole. In 1956
Ganguli conducted investigations on the worker perception of supervisors and an
analysis of their role in the government railway workshop at Kharagpur. The
findings were similar to those found in the western studies.
158
15.3.6. Michigan Studies on Leadership
Likert, Kate, Maccoby, Kalm and Seashore have conducted studies on
leadership behaviour at the Institute for Social Research, Michigan University. The
initial study was carried out by Kate, Maccoby and Morse (1950). This classical
study illustrates the early Michigan approach to leadership. The results showed
that supervisors in charge of high producing section were found to be employee
centered while expressing their attitude. On the contrary, supervisors in charge of
low producing sections were found to be production centered in their orientation.
The study conducted by Lawshe and Nagle (1953) has suggested that the
attitude of supervisors appeared to be related to the productivity of the work group.
Lewin, Lippit and White (1939) studied the behaviour of children of 10 to 11 years
by giving them training in authoritarian, democratic and "laissez faire" leadership.
That is to say, each group was exposed to each of the three kinds of leadership. The
results showed that there was more ego involvement and "we" feeling in the
democratic atmosphere and this was not so in the authoritarian atmosphere. The
authoritarian group shared either a sense of apathy or aggression. But
aggressiveness was very low in the democratic group. Further it was noted that
some boys preferred the autocratic to the democratic order, probably because of
their home background, this interesting finding has been supported by Peaks study
(1945).
15.3.7. Situational Leadership Theory
The situational leadership model is developed by Paul Hersey and Kenneth
Blanchard which suggests that the leadership effectiveness depends upon the
situation in which leadership is exercised. In their model, the authors have
employed two dimensions of leader behaviour as were used in Ohio State University
studies. The two dimensions were task (production-oriented) and relationship
(people-oriented) The level of followers' development, or say, maturity is categorized
into four levels based on their abil ity and willingness to accept responsibility for
completing their task. Followers who are unable and unwilling are categorized as
the least mature, and those who are both able and willing are termed as the most
mature. The model suggests that the two different types of styles are used to
influence the followers of four different levels of maturity as is depicted.
The leaderships style varies across the levels of followers' maturity. A leader
needs to use a telling style of leadership with immature followers who are both
unable and unwilling to take responsibility for completing their work. Once the
followers mature to the second level, the leader needs to exercise a selling style.
Followers further matured i.e., able but unwilling, need to be led by employin g
participating style by the leader. Finally, the most mature followers who are able as
well as willing require to be led by the delegating style of leadership for the simple
reason because the followers accept responsibility entrusted upon them.
What leadership style should be employed at which maturity level of followers
is now tabulated as follows:
159
Table: followers Maturity level Vis- a vis leadership style
S. No. Maturity level Recommended Leadership Style
1. Low ability, low willingness Telling (directive, low support)
2. Low ability, high willingness Selling/ coaching (directive, supportive)
3. High ability, low willingness Participating /supporting (supportive/ low direction)
4. High ability, high willingness Delegating (low direction, low support)
However, one key limitation of the situational leadership model is the absence of
central hypotheses that could be tested. It also does not have a widely accepted
research base which would make it a more valid and reliable theory of leadership.
Nonetheless, the theory has intuitive appeal and is widely used for training and
development in corporation. It has achieved considerable popularity and also
awakened many managers to the idea of situational approaches to leadership styles.
15.3.8 What Makes Leadership Effective?
Although deciding what makes leadership effective seems as if it should be a
simple decision, the theories and research reviewed earlier illustrate the complexity
of the issue. By now, you know that leadership means taking along people in the
fulfillment of certain desired goals or set objectives. Leadership does not mean
imposing willing or unwilling working under one in an office or a factory. In
practice, people are always impressed by something extraordinary and great and
are prepared to follow it if it really touches their hearts. Thus, leadership needs to
win the hearts of others to attain some desired goals. The following points will be of
great help in this regard:
1. Mental and Physical Health
A healthy mind rests in a healthy body. A leader needs to have sound health
both mental and physical to be able to bear the pulls and pressures of his role as
leader. He must also possess stamina and balanced temperament.
2. Knowledge and Intelligence
One most important requirement of a leader is to have required knowledge of
human-behaviour, psychology and professional competence. In order to evince his
convincing competency, the leader also must update himself continuously and keep
renewing himself.
3. Clear-cut and Worthy Goals
Actions without clearut directions lead nowhere. That is why there is very little
achievement inspite of a lot of movement in life. Hence, a leader needs to be very
clear in mind about what to achieve, how to achieve and then reinforce it by a
strong will-power and conviction.
4. Conviction
Swami Vivekananda said "Great convictions are the mothers of great deeds". It
is always man and women with convictions who influence others. There are millions
with opinions but very few with convictions. Leader must have courage of
conviction to impress upon his subordinates.
160
5. Sense of Responsibility
A leader also must be of sense of responsibility for the task assigned to him. In
other words, a leader must discharge his responsibility thrusted upon him willingly
and cheerfully. This enjoins upon us to put our heart and soul into the work, with
single minded dedication, and devotion. This ensures our success in performing the
particular task.
6. Motivation
Effective motivation comes from within not from outside. Strictly speaking, real
motivation cannot be imposed or injected from outside. In order to inculcate
motivation from within the subordinates, a leader needs to have capacity to
appreciate others and look at things from his subordinates angle.
7. Initiative and Drive
You know that electric energy locked up in the power house is of no use unless
it is flown through the cables and manifested itself through the medium of various
gadgets so as to be beneficial. Similarly, passive goodness of leader is never helpful
unless it is action-oriented and result producing. Initiative and drive are, therefore,
the essential prerequisites of effective leadership.
Besides, some writers have identified a number of other factors that influence
leadership effectiveness. The important ones are:
1. The leader's own personality, past experience and expectations.
2. The expectations and behaviour of his superiors.
15.3.9 Training and Methods
There are mainly two types of techniques by which managers can acquire the
knowledge, skills and attitudes and make themselves competent mangers. One is
through formal training and the other is through on-the job experiences
Off- the-Job Training Method
i) Lecture: It is the simplest of all techniques. This is the best technique to
present and explain series of facts, concept and principles. The lecturer
organizes the material and gives it to a group of trainees in the form of talk.
ii) Conferences and Seminars: A conference or seminar is a meeting of several
people to discuss the subjects of common interest. Better contribution from
members can be expected as each one builds upon the ideas of other participants.
iii) Case studies: They are commonly used in managerial training on MBA
university programmes and the like. Cases are prepared on the basis of
actual business situations that happened in various organizations.
iv) Role playing: A problem situation is simulated by asking the participants to
assume the role of a particular person in the situation. The participant
interacts with other participants assuming different roles.
v) Business Games: Under this method, the trainees are divided into groups or
different teams. Each has to discuss and arrive at solutions concerning such
subject as production, pricing, research expenditure, advertising etc.,
assuming it to be the management of a simulated firm.
161
vi) Vestibule Training: In vestibule training, employees are trained on the
equipment they are employed, but the training is conducted away from the
place of work. For training machine shop operator, a vestibule or separate
room is arranged for training in which all necessary equipment and machines
required in an actual machine shop, are duplicated. In pilot training, for
example, airlines use flight simulators for safety, learning efficiency and cost
savings, including savings on maintenance, pilot cost, fuel and the cost of not
having an aircraft in regular services.
vii) Sensitivity Training: The main objectives of sensitivity training are the
development of awareness of sensitivity to behavioural patterns of one self
and others.
Electronic Training
Computerized and internet-based and/or CD-ROM systems to interactively
enhance his or her knowledge or skills. Trainee start with a computer screen that
shows the applicant’s completed employment application, as well as information
about the nature of the job.
Video Conferencing
Companies use video conferencing to train employees who are geographically
separated from each other or from the trainer. This method permits people in one
location to communicate live via a combination of audio and visual equipment with
people in another city or country or with groups in several towns or cities.
Training through the Internet
Many companies use the internet and/or their proprietary intranets to deliver
computer based training. For instance, silicon graphics transferred many of its
training materials to CD-ROMs. Later silicon graphics therefore replaced the CD-
ROM system by distributing training materials via its intranet.
On-the-Job Training Method
i) Job Rotation: The transferring of executives from job-to-job and from
department-to-department in a systematic manner is called Job Rotation.
When a manager is posted to new job as part of such a programme, it is not
merely an orientation assignment. He has to assume the full responsibility
and perform all kinds of duties.
ii) Coaching: In coaching, the trainee is placed under a particular supervisor
who acts as instructor and teaches job knowledge and skills to the trainee.
He tells him what he wants to do, how it can be done and follows up while it
is being done and corrects errors.
iii) Understudy: An understudy is a person who is under training, to assume at
a future time, the full responsibility of the position currently held by his
superior.
iv) Multiple Management: Multiple management is a system in which
permanent advisory committees of managers study problems of the company
and makes recommendations to higher management. It is also called junior
board of executives system.

PRINCIPLES OF SCIENTIFIC MANAGEMENT
16.1. INTRODUCTION
Management means many things to many people. economists regard it as a
factor of production. sociologists see it as a class or group of persons while
practitioners of management treat it as a process in simple terms, management is
what a manger does. it has been called by mary parket follet: “the art of getting
things done through people”. this definition throws light on the fact that managers
achieve organisational goals by arranging others to perform rather than performing
the tasks themselves
16.2 OBJECTIVES
To understand the nature of management.
To gain insights into the historical perspective of management.
To appraise the major contributions to the management thought.

Management, in fact, is much more that no one single definition has been
universally accepted. Nor can anyone definition capture all the facets of
management, given its dynamic nature. That is why, it is often said that there are
as many definitions of management as there are authors in the field. However, the
definition given by James A.F. Stoner encompasses all the important facets of
management. According to him :
“Management is the process of planning, organising, lead ing and controlling
the efforts of organisation members and of using all other organisational resources
to achieve stated organisational goals”. This definition suggests:
Management is a process because all managers irrespective of their level in
the organisation, engage in certain intendedly activities in order to achieve the
desired goals:
Managers use all the resources of the organisation, both physical as well as
human :
Management aims at achieving the organisations goals.
The practice of management is as old as human civilization. In fact much of
the progress of mankind over the centuries may be attributed to the effective
management of resources. The irrigation systems, existence of public utilities, the
construction of various monuments like Taj Mahal, and the Egyptian pyramids of
the bygone era amply demonstrate the practice of management in the olden days
164
also. The ancient civilisations of Mesopotamia, Greece, Rome and Indus-valley
displayed the marvellous results of good management practices. However, the study
of management in a systematic way as a distinct body of knowledge is only of recent
origin. That is why, management is often described as “oldest of the arts and
youngest of the sciences”. Thus, the practice of management is not new. It has been
practiced for thousands of years. But the science part of it ‘the systematic body of
knowledge’ is, no doubt, a phenomenon of the present century.
The traditional management practices remained quite stable through the
centuries until the birth of Industrial revolution in the mid 18th century. The
industrial revolution brought about the substitution of machine power for man
power through several scientific inventions. As a result, within a few decades, the
picture of industrial activity had undergone a metamorphic change. Man’s quest for
new ways of doing things, coupled with his ingenuity in adopting the scientific and
technological inventions in the production of various goods and services resulted in:
Mass production in anticipation of demand :
Advent of corporate form of organisation which facilitate such large scale
production.
Spectacular improvements in the transport and communication facilities ;
Increase in competition for markets :
The Establishment of the new employer - employee relationship and so on.
Industrial revolution had thus sown the seeds of modern management. The
early scientific inquiries into the practice of management began. In what follows in
this lesson, the evolution of management thought over the years is discussed in a
chronological way.
Management Levels
Though the terms ‘manager’ is used to mean anyone who gets the things done
through other people, we find the managers in any organisation with varying
authority and responsibilities. In any company the total management job requi res
many skills and talents. Obviously, therefore, the job of manager is divided and
subdivided. Such an arrangement implies different levels of management.
Front - Line Managers
This is the entry level job in the management. Managers at this level direct the
operating employees (workers). They are close to the action, for their job involves
supervising the activities of operatives. Front-Line managers are called foreman,
supervisor, inspector and so on in any organisation.
Middle Level Managers
Middle management level includes in many organisations, more than one level.
Managers who work at all the levels between the lower and top levels constitute the
middle management. Department heads, Regional managers, Zonal managers and
the like fall in this category. They report to top managers. Their principal
165
responsibilities are to direct the activities of lower level managers who implement
the organisation’s policies.
Top level Managers
This level consists of a small group of executives. Board of Directors,
Chairman, Managing Director and the top functional heads and divisional
managers comprise this level. Top managers are responsible for the overall
management of the organisation. They decide the enterprise objectives, policies and
strategies to be pursued to achieve those objectives. They provide direction to the
organisational by guiding the organisation’s interactions with its environment.
16.3.1. MANAGEMENT AS A SCIENCE
It is therefore relevant to examine the exact nature of management whether it
is a science or an art. ‘Before arriving at a conclusion, let us understand the nature
of science as well as art. Any branch of knowledge to be considered as science, (like
the ones we have physics, chemistry, engineering, etc.,) should fultil the following
conditions :
The existence of a systematic body of knowledge encompassing a wide array of
principles :
The principles have to be evolved on the basis of constant enquiry and
examination ;
The principles must explain a phenomenon by establishing cause - effect
relationship;
The principles have to be amenable for verification.
Looked at from this angle, management as a discipline fulfils the above
criterion. Over the years, thanks to the contributions of man thinkers and
practitioners. management has emerged with own principles. The application of
these principles helps any practising manager to achieve the desired goals.
However, while using the principles, one should not lose sight of the variables in
the situation, since situations differ from one another. Thus, the importance of
personal judgement cannot be undermined in the application of principles. Further,
management is a dynamic subject in that it has drawn heavily from economics,
psychology, sociology, engineering and mathematics, to mention a few. It is multi-
disciplinary in nature. But a word of caution. Though management, considering its
subject matter and the practical utility, may be considered as ‘Science’ for reasons
discussed below, it cannot be viewed as an’ exact science’.
16.3.2. Scientific Management ERA
Frederick Winslow Taylor (1856-1915) should be ever remembered for his
contribution to the management movement. In an effort to address several
organisational problems. Taylor developed the body of knowledge what is now called
“Scientific management”. Taylor investigated the effective use human beings at the
shop floor level in the industrial organisation. He defined managing as the art of
“knowing exactly what you want men to do and then seeing that they do it in the
166
best and cheapest way”. For the emphasis he had placed on the scientific way of
doing things, he is often called the “father of scientific management”.
16.3.3. Salient Features of Scientific Management
Taylor conducted various experiments at the work place to find out how
human beings could be made more efficient by standardising the work. These
experiments have provided the following features of scientific management.
i. Separation of planning and doing
Taylor emphasized the separation of planning from actual doing. Before
Taylor’s Scientific Management, a worker used to plan about how he had to work
and what instruments were necessary for that. This was creating lot of problems.
Taylor insisted that planning should be left to the supervisor and the worker should
concentrate on doing the work.
ii) Functional Foremanship
Separation of planning from doing resulted in the development of
supervision system. For this purpose, Taylor evolved the concept of functional
foremanship based on specialization of functions.
iii. Job analysis
According to Taylor the best way of doing a job is one which requires the least
movements. consequently less time and cost. He analysed the various jobs to find out
the best way of doing the things with the help of Time and Motion and Fatigue studies.
a) Time study involves the determination of time, a movement takes to
complete. The movement which takes minimum time is the best one. This helps in
fixing the fair work for a period.
b) Motion study involves the study of movements which are involved in doing a
job and thereby elimination the wasteful movements and performing only necessary
movements.
c) Fatigue study shows the amount and frequency of rest required in completing
the work. Thus job analysis, as given by Taylor, suggests the fair amount of a day’s
work requiring certain movements and rest periods to complete it.
iv. Standardization
Instruments and tools, period of work, amount of work, working conditions
and cost of production have to be standardized on the basis of job analysis and
various elements of costs that go into the job.
v. Scientific Selection and Training of Workers
Taylor suggested that workers should be selected on a scientific basis taking
into account their education, work experience, aptitude, physical strength, etc., A
worker should be given work for which he is physically and technically most
suitable. Apart from selection, proper emphasis should be laid on the training of
workers to make them efficient and effective.
vi. Financial Incentives
167
Taylor introduced financial incentives to motivate workers to put in their maximum
efforts. he applied the concept of differential piece rate system. According to this scheme, a
worker who completes the normal work gets wages at higher rate per piece and one who does
not complete gets at lower rate. To make the differential piece rate system work, he has
suggested that wages should be based on individual performance.
vii. Economy
While applying scientific management, not only scientific and technical aspects
should considered but adequate consideration should be given to economy and
profit. For this purpose, techniques of cost estimates and control should be
adopted. The economy and profit can be achieved by making the resources more
productive as well as by eliminating the wastages.
viii. Mental Revolution
Taylor strongly suggested a change in the attitude of employees and
employees. Mutual conflict should be replaced by mutual cooperation which is
beneficial to both. Taylor argued that mental revolution is the most important
feature of scientific management because in its absence, no principle of scientific
management could be applied.
In his crusade against the unscientific methods of management which were
prevalent at that time. Taylor had to face bitter criticism from different quarters. It
is an irony that in the beginning both workers and the managements did not
understand Taylor’s preaching’s correctly. Workers had struck work in protest
against the proposed changes in the work routine and systems. The American
congress had even called Taylor for an explanation. Taylor’s philosophy, in simple,
as reiterated by him before the congress and also in his book “The principles of
Scientific Management”. rested on the following four basic principles :
the development of a true science of management, so that the best method for
performing each task could be determined :
The Scientific selection of the workers, so that each worker would be given
responsibility for the task for which he or she was best suited :
The scientific education and development of the worker: and
Intimate, friendly co-operation between management and labour.
16.3.4 Management Principles
F.W Taylor
In 1911, Frederick Winslow Taylor published his work, The principles of
Scientific Management, in which he described how the application of the scientific
method to the management of workers greatly could improve productivity.
Scientific management methods called for optimizing the way that tasks were
performed and simplifying the jobs enough so that workers could be trained to
perform their specialized sequence of motions in the one "best" way. Prior to
scientific management, work was performed by skilled craftsmen who had learned
their jobs in lengthy apprenticeships. They made their own decisions about how
168
their job was to be performed. Scientific management took away much of this
autonomy and converted skilled crafts into a series of simplified jobs that could be
performed by unskilled workers who easily could be trained for the tasks.
Taylor became interested in improving worker productivity early in his career
when he observed gross inefficiencies during his contact with steel workers.
Taylor's 4 Principles of Scientific Management
After years of various experiments to determine optimal work methods, Taylor
proposed the following four principles of scientific management:
1. Replace rule-of-thumb work methods with methods based on a scientific
study of the tasks.
2. Scientifically select, train, and develop each worker rather than passively
leaving them to train themselves.
3. Cooperate with the workers to ensure that the scientifically developed
methods are being followed.
4. Divide work nearly equally between managers and workers, so that the
managers apply scientific management principles to planning the work and
the workers actually perform the tasks.
These principles were implemented in many factories, often increasing
productivity by a factor of three or more. Henry Ford applied Taylor's principles in
his automobile factories, and families even began to perform their household tasks
based on the results of time and motion studies.
Drawbacks of Scientific Management
While scientific management principles improved productivity and had a
substantial impact on industry, they also increased the monotony of work. The core
job dimensions of skill variety, task identity, task significance, autonomy, and
feedback all were missing from the picture of scientific management.
While in many cases the new ways of working were accepted by the workers, in
some cases they were not. The use of stopwatches often was a protested issue and
led to a strike at one factory where "Taylorism" was being tested. Complaints that
Taylorism was dehumanizing led to an investigation by the United States Congress.
Despite its controversy, scientific management changed the way that work was
done, and forms of it continue to be used today.
Scientific management, or Taylorism, is a management theory that analyzes
work flows to improve economic efficiency, especially labour productivity. This
management theory, developed by Frederick Winslow Taylor, was popular in the
1880s and 1890s in manufacturing industries. While the terms "scientific
management" and "Taylorism" are often treated as synonymous, an alternative view
considers Taylorism to be the first form of scientific management. Taylorism is
sometimes called the "classical perspective," meaning that it is still observed for its
influence but no longer practiced exclusively. Scientific management was best
known from 1910 to 1920, but in the 1920s, competing management theories and
methods emerged, rendering scientific management largely obsolete by the 1930s.
169
However, many of the themes of scientific management are still seen in industrial
engineering and management today. Important components of scientific
management include analysis, synthesis, logic, rationality, empiricism, work ethic,
efficiency, elimination of waste, and standardized best practices . All of these
components focus on the efficiency of the worker and not on any Frederick Winslow
Taylor Frederick Winslow Taylor is considered the creator of scientific management.
specific behavioural qualities or variations among workers. Today, an example of
scientific management would be determining the amount of time it takes workers to
complete a specific task and determining ways to decrease this amount of time by
eliminating any potential waste in the workers' process. A significant part of
Taylorism was time studies. Taylor was concerned with reducing process time and
worked with factory managers on scientific time studies. At its most basic level,
time studies involve breaking down each job into component parts, timing each
element, and rearranging the parts into the most efficient method of working. By
counting and calculating, Taylor sought to transform management into a set of
calculated and written techniques.
Frank and Lillian Gilbreth
While Taylor was conducting his time studies, Frank and Lillian Gilbreth were
completing their own work in motion studies to further scientific management. The
Gilbreths made use of scientific insights to develop a study method based on the
analysis of work motions, consisting in part of filming the details of a worker's
activities while recording the time it took to complete those activities. The fil ms
helped to create a visual record of how work was completed, and emphasized areas
for improvement. Secondly, the films also served the purpose of training workers
about the best way to perform their work. This method allowed the Gilbreths to
build on the best elements of the work flows and create a standardized best
practice. Time and motion studies are used together to achieve rational and
reasonable results and find the best practice for implementing new work methods.
While Taylor's work is often associated with that of the Gilbreths, there is often a
clear philosophical divide between the two scientific management theories. Taylor
was focused on reducing process time, while the Gilbreths tried to make the overall
process more efficient by reducing the motions involved. They saw their approach
as more concerned with workers' welfare than Taylorism, in which workers were
less relevant than profit. This difference led to a personal rift between Taylor and
the Gilbreths, which, after Taylor's death, turned into a feud between the Gilbreths
and Taylor's followers. Even though scientific management was considered
background in the 1930s, it continues to make significant contributions to
management theory today. With the advancement of statistical methods used in
scientific management, quality assurance and quality control began in the 1920s
and 1930s. During the 1940s and 1950s, scientific management evolved into
operations management, operations research, and management cybernetics. In the
1980s, total quality management became widely popular, and in the 1990s "re-
170
engineering" became increasingly popular. One could validly argue that Taylorism
sent the groundwork for these large and influential fields we practice today.

LESSON - 17
COST, DEPRECIATION AND VALUATION
17.1. INTRODUCTION
Cost function plays a vital role among all the functions of an organisation to
ensure success and organisational growth in the environment of global competition.
Generally fixed assets, except land, such as Plant and Machinery, Furniture,
Buildings and Equipment have a short period of useful life. As these assets are
permanently used in the business they necessarily go down in value in course of
time. Depreciation is thus, diminution in the value of a fixed asset due to use and /
or the lapse of time.
The term depreciation is derived from the Latin words ‘do’ (meaning down) and
‘pretium’ (meaning price) in business, it is used to denote loss or value which arise
through wear and tear or some other form of material deterioration or the affluxion
of time.
17.2 OBJECTIVES
To impart an understanding about installation of Cost accounting.
To familiarise you the basic costing concepts, principles and types of cost.
To acquaint you with the different costing techniques available to exercise
cost control.
To give brief note about different methods of Depreciation.
To explain the managerial significance of Depreciation Accounting.
To know about the value and value analysis

17.3.1. COST ACCOUNTING
The cost control has to happen at the point of incurrence and it is necessary
that the facilities available are fully utilized to swell the volume of operations which
will automatically bring down the cost per unit. The impact of volume on Cost Per
Unit is certainly a measure of efficiency, productivity and the intensity of utilisation
of resources.
Cost Accountancy has many aspects like cost accounting, budgetary control,
cost control and cost audit. Cost accounting denotes the formal mechanism by
means of which costs are ascertained.
173
Cost Accounting is classifying, recording and appropriate allocation of
expenditure for the determination of the costs of products or services, and for the
presentation of suitably arranged data for purposes of control and guidance of
management.
“It is the application of costing and cost accounting principles, methods and
techniques to the science, art and practice of cost control and the ascertainment of
profitability. It includes the presentation of information derived there from for the
purpose of managerial decision - making”
Institute of Cost and Management Accountant (ICMA), London.
The term ‘Cost Accountancy’ includes Costing and Cost accounting. Its
purposes are Cost-control and Profitability - ascertainment. It serves as an
essential tool of the management for decision-making.
Costing and Cost Accounting
It is defined as “the classifying, recording and appropriate allocation of
expenditure, for the determination of costs, the relation of these costs to sale value
and the ascertainment of profitability”. So this is a technique and processes of
ascertaining costs.
Cost Accounting
“The process of accounting for cost from the point at which expenditure is
incurred of committed to the establishment of its ultimate relationship with cost
centres and cost units. In its widest usage it embraces the preparation of statistical
data, the application of cost control methods and the ascertainment of the
profitability of the profitability of activities carried out or planned” - ICMA.
It is defined as “the application of accounting and costing principles
methods and techniques in the ascertainment of costs and the analysis of savings
and / or excesses as compared with previous experience or with standards.” So it is
a formal system of accounting for costs by means of which costs of products and
services are ascertained and controlled.
Applications of costing
The application is wide. All types of activities, manufacturing and non
manufacturing in which monetary value is involved. Wholesalers, retailers, banking
and insurance companies railways, hotels, hospitals, colleges and the like, all have
to adopt cost accounting techniques to operate efficiently.
17.3.2. OBJECTIVES OF COST ACCOUNTING
1. To ascertain the cost per unit of the different products manufactured by a
business concern.
2. To provide a correct analysis of cost both by process or operations and by
different elements of cost.
3. To disclose sources of wastage and to prepare such reports which may be
necessary to control such wastage.
4. To furnish requisite data to guide in fixing the price.
174
5. To ascertain the profitability.
6. To exercise effective control of stocks.
7. To advice management on future expansion.
8. To help in the preparation of budgets.
9. To assist in taking various financial decisions such as introduction of new.
products, replacement etc.
10. To organise cost reduction programmes with the help of different department
managers.
11. To offer specialized services of cost audit in order to prevent the errors and
frauds and to facilitate prompt and reliable information of the Management.
12. To provide suitable means and information to the top management to control
and guide the operations of the business organisation.
13. To compare actual costs with the standard costs and analyse the causes of
variation.
14. To contribute necessary information to develop cost standards and to
introduce the system of budgetary control.
15. To enable the management to know where to economic on costs, how to fix
prices, how to maximize profits and so on.
16. Cost accounting provides management with cost data relating to products,
processes, jobs and different operations in order to control the costs and
maximize the earnings. It plays’ a vital role in all the business activities.
17.3.3. ESSENTIALS OF INSTALLING COSTING SYSTEM
The general considerations to be observed in installing a costing system are as
follows :
The Objective: Whether the objective of installing the costing system is
limited to a specific area, e.g. material management, or fixing selling price, or to
arrive at a certain managerial decision or the object is to install the system for
covering all the aspects of cost affecting the business. The approach to install the
system will be dependent on its objective.
The Area of Operation: Having decided the objective, the areas of operation of
the system are to be studied, by which the management can be best benefited. If
production is slack, attention will have to be paid to increase if production is good
but the sales are receding, study will be made to increase the sales and action
taken according to the results of study and analysis. Such areas, which require
immediate attention, are to be carved out on priority basis to be handled by the
cost system.
The Organisation of the Business: No system of cost installation would
succeed until the organisation structure of the business is taken into account. The
organisational part would help to determine the scope of working and improvement.
If the interest of management call for certain minor changes in the organisational
structure, to its advantage, the same may have to be done.
175
The Conception & Reception of the Idea: The idea of the installation of the
cost system is to be placed before the staff and the workers in a manner that it is
well received and not objected to on flimsy grounds. The success of the system
would depend on the co-operation of the persons engaged in the enterprise, and the
co-operation will be forth coming only if the idea and plans are well conceived and
received. The benefits of introducing the system to all the sections should be well
explained.
Collection of Data & Prompt Information: The cost data works as a base for
decision making. There should be evolved a proper system for the collection of the
required cost data and information promptly. Secondly, there should be a system to
verify the correctness of the data supplied, otherwise the conclusions drawn would
be wrong and time spent in its working would go waste.
Cost Records & Cost Books: The maintenance of cost records and cost books
depends on the size and nature of the business, but the basic requirements. The
manner in which the financial accounts could be interlocked into an integral
accounting system has to be studied and worked out. Decision has to be taken if
two separate set of books-one for financial accounts and other for cost accounts-
have to be maintained and thereafter the results are to be reconciled. Proper books
and records are to be kept and maintained to meet the requirements of either of the
two situations mentioned above.
Control system for the Elements of Cost: System would have to be devised
for recording and controlling costs of materials, labour and overheads, in
accordance with costing principles and procedures.
Type and Method of Costing: The choice of method of costing would depend
on the nature of production, e.g. Job Cost method or the Process Cost method. For
cost control, standard costing along with budgetary control may have to be selected
and applied. Similarly, for decision-making, Marginal and Differential costing
techniques may be found useful. Preparations for the application of the particular
method and technique / type should be made initially.
Responsibility Accounting: Responsibility accounting is a technique of cost
control by delegating, etc., known as responsibility centres. It has to be judged
whether a particular official who had been assigned a particular function, has
implemented the same or not within the time allotted to him, or not, and thus the
responsibility has got to be fixed for failure-action on individual persons, for the
sake of control of cost. For this purpose, a system of responsibility accounting
should be evolved.
The specific considerations as distinct from general considerations to be kept
in view while installing a cost system are as follows :
Size and Nature of Business: In a business of big size, a detailed cost system
is necessary while in a small business, the system should be within the
requirements so that the expenses on the installation and its working may not out-
weigh the utility.
176
The cost system is good for business engaged in manufacturing or in service -
rendering concerns but for others. Even in production enterprise like colliery where
the production costs are all direct costs, the financial accounts may be so designed
as to obviate the need of any cost system, unless otherwise called for.
Products: The nature of product determines the method of costing to be applied. If
the material content of the product is more valuable, the material cost records need be kept
in comparatively more elaborate manner so as to make material cost control effective.
Same is the position with regard to labour and overhead.
Organisation: The organisational set up for a costing system should be
modelled that the control part is exercised by the Cost Accountant, as such, the
present organisational set up of the costing department need close study to suggest
necessary changes.
Functional study: The functional divisions of an undertaking based on cost
are a) Manufacturing, b) Administration, and c) Selling & Distribution. A study of
the present working of the different departments is necessary to suggest
improvements.
17.3.4. ELEMENTS OF COST
For proper control and managerial decisions management is to be provided
with necessary data to analyse and classify costs. For this purpose the total cost is
analysed by elements of cost based on nature of expenses. The elements of cost are
further analysed into different elements as follows.
By grouping the above elements of cost, the following division of cost are
obtained;
1. Prime cost-Direct materials + Direct labour + Direct expenses
2. Works of factory cost - Prime cost + works of Factory overheads
3. Cost of production - work cost - Administration overheads.
4. Total cost or cost of sales- cost of production + selling and distribution
overheads.
The difference between the cost of sales and selling Price represents profit or
loss.
Direct Materials
It is the one which can be identified in the product and can be conveniently
measured and directly charged to the product, Ex: Timber in furniture.
Classification of direct materials
1. All raw materials like jute in the manufacture of gunny bags pig iron in
foundry and fruits in eating industry.
2. Materials specifically purchased for a specific job, process or order like glue
for book binding, starch powder for dressing yarn.
3. Parts or components purchased or produced like batteries for radio.
4. Primary packing materials like cardboard box.
177
Indirect materials
In some cases, though the material is a part of the finished product yet it is
not treated as direct materials. ex: nails in furniture making. This is because it is
used in small quantities. Even certain items which do not physically become a part,
of the finished products, ex: coal, Greece etc.
Direct Labour
It includes payment made to the following groups of labour :
1. Labour engaged on the actual production of the product in carrying out an
operation or process.
2. Labour engaged in aiding the manufacture by way of supervision
maintenance, tools setting, transportation of material cost.
3. Inspectors, analysis etc, specially required for such production.
Indirect Labour
It is of general character and cannot be conveniently identified with a
particular cost unit. Indirect labour is not directly engaged in the production
operations but only to assist or help in production operations, direct or chargeable
expenses. It includes all expenditures other than direct material or direct labour
that are specifically incurred for a particular product. Such expenses is charged as
part of the - prime cost. Ex: Excise duty, Royalty.
Overheads: It may be defined as the aggregate of the cost of indirect materials,
indirect labour and such other expenses including services as cannot conveniently
be charged direct to specific cost units. Thus, overheads are all expenses other than
direct expenses. In general terms overheads comprise all expenses incurred for or
in connection with the general organisation of the whole or part of the undertaking.
The main groups into which overheads may be sub-divided are the following.
1. Manufacturing overheads.
2. Administration overheads.
3. Research and Development overheads.
Expenses excluded from costs: The total cost of a product should include
only those items of expenses which are a change against profit. Items of expenses
which are relating to capital assets, capital losses, payments by way of distribution
of profits and matters of pure finance should not form a part of the costs. ex:
Income tax, dividends etc.
Cost sheet or statement of cost: It is to show the output of a particular
accounting period along with break-up of costs. The date incorporated in cost sheet
are collected from various statements of accounts which have been written in cost
account either day-to -day or regularly records.
It is generally presented in column in the form of total cost of current period,
per unit for the period, total cost per unit etc. Cost sheet is a Memorandum
statement. Therefore, it does not form part of double entry cost accounting records.
178
Advantages
1. It discloses the total cost and the cost per unit of the units produced during
the given period.
2. It enables a manufacturer to keep close watch and control over the cost of
production.
3. By providing a comparative study of the various elements of current cost with
the past results and standard costs, it is possible to find out the causes of
variations in costs and to eliminate the adverse factors and conditions which
go to increase the total cost.
4. It acts as a guide to the manufacturer and helps him in formulating a definite
useful production policy.
5. It helps in fixing up the selling price more accurately.
6. It helps the businessman to minimise the cost of production when there is a
cut throat competition.
7. It helps the businessman to submit quotations with reasonable degree of
accuracy against tenders for the supply of goods.
17.3.5 DEPRECIATION
“Depreciation represent that part of the cost a fixed asset to its owner, which is
not recoverable when the asset is finally put-out of use by him. Provision against
this loss of capital is an integral cost of conducting the business during the effective
commercial life of the asset and is not dependent upon the amount of profit cleared.
The Institute of Chartered Accountants of Australia
“Depreciation is the allocation of the entire cost of depreciable assets to the
operating expense of a series of fiscal period”.
Mr. Montgomery
“Depreciation is the process of spreading the value of a fixed asset over
accounting periods comprising its service life”.
17.3.6 METHODS OF DEPRECIATION
1. Straight - line Method
As this method is very simple and easy to understand, it is widely used. This is
otherwise as “Fixed Instalment method” or “Original Cost System”. Under this
method a fixed amount is to be charged as depreciation for each year of expected
use of the asset. The annual charge is computed by dividing the depreciable cost,
total cost minus salvage value by the estimated working life expressed in years.
Suppose an asset is purchased for Rs. 80,000 and its residual value at the end of
its tenth year of life during the course of 10 years at the rate of Rs. 7,200 per year.
It is suitable for use in connection with patents. leaseholds and machinery etc, as
depreciation is connection with patents, leaseholds and similar assets having a
definite life and it is not suitable for plant and machinery etc. as depreciation is
constant while the repairs will be heavy in later years. This method is generally
followed regarding ocean going ships etc.
179
2. Service - Hours Method
This method takes into consideration the “running time” of the asset for the purpose of
calculating the amount of depreciation. For example, in the case of air-craft the estimated
useful life may be calculated in terms of “flying hours”. The formula is,
D= C – S
× Service Hours n
This method is useful 1) where obsolescence is not a primary factor 2) use of
asset can be measured in terms of time and 3) the utility of the asset is directly
related to its working time.
3. Productive Output Method
In this method it is essential to make an estimate of the units of output the
asset will produce in its lifetime. For example, in case of a truck, estimated useful
life may be in terms of kilometres operated and for a stamping machine, a certain
number of stamps. Depreciation is calculated as under.
D= C – S
× units of output n
4. Diminishing Balance Method
This method is otherwise known as Reducing Balance Method or Written Down
Value Method. This method yields its diminishing annual depreciation charges by
applying a constant rate to the written down value of the cost an asset. Here
depreciation is provided on the basis of a percentage. Though this percentage
remains the same, the actual provision drops year after year, because the
percentage is based on the diminishing value. Suppose the cost of an asset is
Rs.20,000. At the rate of 10% depreciation for the first year is Rs. 2,000. For the
next year it is Rs. 1,800
(20,000-2,000=18,000 × 10 ).
100
It is clear that the depreciation is written off on the basis of the balance in the
account of the asset.
The main advantage of this method is that the decreasing depreciation charges
in the later years on a asset’s life fund to compensate the increasing cost of
maintenance and repairs as the asset grown older and thus help to make the total
cost of using the asset more or less content. Hence, this method is suitable for a
assets like plant and machinery, boiler, lorry, motor, car and buildings.
5. Sum of the years Digit Method
Depreciation rate, under this method is expressed a fractions. For getting the
fractions, one has to add the numbers representing the period of life, use the sum
thus obtained as a denominator and use as numerator, the same numbers take in
reverse order and finally multiply the net asset value by the fractions thus
produced. For example a fixed asset costing Rs. 50,000/- (Rs. 10,000/- residual
180
value) with estimate useful life of 5 years the denominator of the fraction for each
would be 15 (1+2+3+4+5) years The allowable depreciation, for the first year is 5/15
of cost, for second year 4/15 of the cost and so on.
6. Double Declining Balancing Method
Under this method the depreciation is charged on the reducing balance
method but the rate of depreciation is determined by multiplying the straight line
rate by two. Here residual value is ignored. This method is often used in the U.S.A.
7. Revaluation Method
Assets such as Loose Tools, Pattern Copyrights, Models Livestock, Packing
Materials, Bottles, Jigs etc, Cannot be depreciated under Straight Line Method or
Reducing Method, as they do not depreciate uniformly. So they are revalued at the
end of each accounting year. The difference between the opening value and the
revaluated amount is treated as used cost or depreciation. This method is ideal for
special utility assets purchased for use on a specific project and whose utility at the
end of the project is problematical. If the revaluation discloses any appreciation in
the value of asset it should be treated as capital reserve.
8. Replacement Method
This system is frequently utilised in public utility companies. This system does
not record depreciation until a unit is replaced. When unit is replaced at time, the
amount equal to the cost of the new assets (less the residual value of the old asset)
is charged to depreciation.
9. Annuity Method
Earlier methods ignore interest on the capital sunk in the acquisition of the
asset. Hence, this method takes the case of the fact that the business decides
losing the original cost of the asset also loses interest (on the amount used for
buying the asset) which he would have earned had the same amount been invested
in some other form of investment. Under this system the amount of total
depreciation is determined by adding the cost of asset and interest thereon at an
expected rate. As the calculation of depreciation is difficult, a depreciation Annuity
Table has been specially constructed for this purpose. This shows the amount that
can be written down annually, as depreciation on the asset along with a certain
rate of interest on the capital sunk, in the asset. The depreciation to be written off
can be found out from the Annuity Table.
This system is an exact method of providing depreciation. It is applicable only
to leaseholds which generally involve considerable capital outlay over a specific
term of years. It is not applicable to plant and machinery as they are subject to
frequent calculations on account of additions and dismantling of them.
10. Depreciation Fund Method
The method is otherwise known as Sinking Fund Method. This system
combines both the depreciation of asset and its replacement under one
comprehensive approach of providing ready cash for purchasing new asset at the
time of replacing the old one. For this purpose the depreciation amount is set aside
181
and invested in Government bonds, Securities etc. Interest on these investments is
also invested on similar investments. When the life of the asset comes to an end,
the securities are sold and a new asset is purchased with the help of the sale
proceeds. The amount that is kept aside as depreciation and invested every year is
such that the accumulated amount with compound interest, will be equal to the
cost of the asset, less residual value if any, at the time when it becomes worthless
to the business. For this purpose “Sinking Fund Table” is used which shows how
much is to be invested every year to get Re. I for some years with certain percentage
of interest. Such figure is multiplied by the value of asset.
11. Insurance Policy Method
It is similar to Depreciation Fund Method instead of making investments,
arrangements are made with an insurance company which will receive premium
annually and pay at the end of the fixed period the required amount. The premium
amount has to be paid in the beginning of each year. The annual premium is
treated as the annual depreciation. The amount is credited every year to the
Depreciation Fund Account by debiting Depreciation Account. Fund Account by
debiting Depreciation Account. On payment of the premium. Depreciation fund
Policy Account is debited. Here there is no entry for interest as no interest will be
received from the Insurance company.
12. Depletion Method
This method is most suitable for mines, quarries etc, from which a certain
quantity of output is expected to be obtained. The value of mine depends only upon
the quantity of minerals that be obtained. When the whole quantity is taken out,
the mine loses its value. Hence, one can say that the mine depreciates according to
the quantity mined. The rate of depreciation is worked out as so much per tonne. It
is obtained by simply dividing the cost of the mine by the total quantity of the
mineral expected to be available.
17.3.7. VALUATION
This is a process which is useful for managerial decision making by which
unnecessary costs are indentified and eliminated without impairing the quality and
efficiency. It is also concerned with exploring channels of performance improvement
and in endeavours to get value for a given cost by a continuous process of planned
action.
This is an effective tool of cost reduction value analysis probe into the
economic attributes of value. It improve performance, increases the value of the
product and reduces the costs by a continuous process of planned action.
Value and value analysis
Value is used in a broader sense and it has different meanings for different
persons. Ex. For Management it is the return on investment.
TYPES OF VALUE
i) Use value
There are certain characteristics of a product which make it useful for certain
purpose.
182
Example
Pen for writing, it measures the quality of performance of a product. The use
value may be primary and secondary. Primary use value indicates the attributes of
a product which are essential for its performance as engine, steering wheel and axle
in a motor car without which car cannot move. Secondary use value refers to such
devices as bonnet or the mudguard or the wind screen without which motor car can
be driven but they are necessary for the protection of engine and other parts.
Esteem value: Certain properties of product do not increase its utility or
performance but they make it esteemable which would induce customers to
purchase the product. ex: Going for Palmolive soap though Lifebuoy serves the
purpose.
Cost value: The value is measured in terms of cost involved :
Exchange value: Certain characteristics of a product facilitate its exchange for
something else and what are the exchange value of that product.
Value analysis: It seeks to provide the different values required in a product or
service at the least cost without impairing its qualify, efficiency and attractiveness.
Relationship between value, function and cost
Value = Function
Cost
Value can be improved by the following ways :
a) by improving function, cost remaining constant
b) by improving cost, function remaining constant
c) by improving function and reducing cost.
17.3.8 PROCEDURE OF VALUE ANALYSIS
1. Identification and definition of the problem.
2. The feasibility of the alternatives and exploring the best method of performing
the work at the minimum cost.
3. The investment, if any, required for the alternative.
4. Percentage of the return on new investment.
5. Costs resulting indirectly out of a decision to change to alternative like costs of
items becoming obsolete, cost training etc.
6. The benefits from the alternative like reduction in costs and increased
revenue.
7. Recommendation of the final proposal for implementation after considering the
above points which will increase use value or esteem value.
Techniques of value analysis
Lawrence & Miles of the General Electric company who is known as the father
of value analysis has developed the following techniques :
183
1. Work is specific
Here people at the top will be influenced by the specific proposal and it is
possible that the right manufacturing process may be developed after careful
examination. Hence, avoid generalities because they serve only to prevent changes
and protect the status quo.
2. Obtain all available costs
Information about all available costs should be obtained. The specific method
may slightly increase cost in department but may lead to reduction in other
departments resulting in overall reduction. Relevant costs for each function may be
obtained, if not available it must be calculated accurately.
3. Information from the most Authentic Source
Information on any aspect of cost, methods of manufacture, finishing packing
etc., should be obtained from the most reliable source. To get the correct
information, a questionnaire should be developed. The following things may be
taken care while collecting information.
a) Design of the product and its value.
b) Relationship of cost proportionate to the use value or esteem value.
c) Selecting the essential features alone.
d) Searching for better substitute.
e) Chances of reducing the material cost.
f) Deciding whether all labour operations are necessary.
g) Possibility of standardisation and simplification of products.
4. Evaluate function by comparison
Here comparison is made with the functions of other concerns, the cost etc.
This will lead to a number of alternatives which can be examined to see if any of
them is likely to result in a cheaper but reliable alternative.
5. Discuss with specialists and take advantage of their expertise knowledge
It is highly needed to get specialised knowledge form suitable specialist,
without such expertise knowledge status quo will be continued and opportunity of
improving value and reducing cost will be lost.
6. Use real creativity
Value analysis involves a creative appeal for finding out unnecessary costs.
The human mind is capable of developing new ideas which lead to cost reduction
and performance improvement. Creative thinking can be helpful in cost reduction
by simplifying the existing part or item to do the same function.
7. Consult your suppliers for new ideas
As your suppliers are dealing with many others who are in the same line of
business, their ideas and suggestions will be great help to you.
184
8. Use Standard parts whenever possible
Standard parts are interchangeable and cheaper than specially made parts
because parts are generally made by mass production methods leading to reduced
costs. Specially made parts should be used only when it is unavoidable to do so.
9. Refine ideas till only one acceptable alternative remains,
10. Get the maximum cooperation from colleagues to other department with whom you
have to deal.
Advantages of value analysis
1. It is a powerful tool for cost reduction because its basic objective is the
identification of unnecessary costs in a product or service and efficiently
eliminating them without impairing its quality and efficiency.
2. It is scientific tool for increasing the productivity of a concern because it
aims at exploring various alternatives for efficient use of all types of resources in
employment and making available goods and services of the kind and quality most
wanted by customers, at lower and lower costs.
3. It helps to keep management abreast of the latest technology and other developments
because value analysis aims at examining new methods and techniques of doing things with a
view to reducing the cost and increasing the value of the items.
4. It ensures the fullest possible use of resources because it aims at
eliminating all unnecessary costs.
5. It induces the creative ability of the staff because it involves a creative
approach for finding out unnecessary costs.
6. It creates proper atmosphere for increased efficiency because it aims at a
continuing research for improvement in efficiency.
7. It is helpful in any drive for import substitution because i t explores new
methods and techniques of manufacturing indigenous goods which may serve the
same purpose.
8. It can be applied at the stage from initial design stage of an item right up to
the final stage of its packing and dispatch because it aims at iden tifying
unnecessary costs at all levels with a view to eliminating them systematically.

JOB EVALUATION, WAGE AND INCENTIVES
18.1. INTRODUCTION
Job evaluation is a practical technique, designed to enable trained and
experienced staff to judge the size of one job relative to others. Job evaluation is the
outcome of job analysis. Job analysis provides the information necessary for appraising
or evaluating a job like tasks to be performed in a job, skill, knowledge, abilities,
aptitude etc., necessary to carry out the tasks, responsibilities, authority and
accountability requirements to perform a job successfully. Job description and job
specification and employee specification are three sub-systems of job analysis. Job
description provides the information relating to minimum acceptable human qualities
like knowledge and skill necessary to perform a job. Employee specifications indicate
minimum employee qualifications like physical, educational, behavioural etc., which
represent the possession of minimum acceptable human qualities. Thus, job analysis
provides information necessary for job evaluation Employees are paid in monetary
and non-monetary forms for their work. The former is the most basic elements by
which individuals are attracted towards an organisation is the wage or salary. The
monetary compensations are primary and incentive. The primary compensation is
the wage or salary, wage is used to denote payments to hourly-rated production
workers and the salary is used to denote payment to clerical, supervisory and
managerial employees.
18.2 OBJECTIVES
To compare the duties, responsibilities and demands of a job with that of
other jobs.
To determine the hierarchy and place of various jobs in an organization.
To understand the different methods
Solving wage controversies
To distinguish among minimum wage, living and fair wage
To understand the different methods of wage payment
To analyse the types of wage incentive plans

19.3.1 Job evaluation
Job evaluation deals with money and work. It determines the relative worth or
money value of jobs. The International Labour Organisation defined job evaluation
as, “an attempt to determine and compare demands which the normal performance
of a particular job makes or normal workers, without taking into account the
individual abilities or performance of the workers concerned”.
Wendell L. French defined job evaluation as, “a process of determining the
relative worth of the various jobs within the organization so that differential wage
may be paid to jobs of different worth”.
Job evaluation is defined as, “the overall activity of involving as orderly,
systematic method as procedure of ranking, grading and weighting of jobs to
determine the value of a specific job in relations to other jobs”.
British Institute of Management (1970) defined job evaluation as “the process
of analyzing and assessing the content of jobs. In order to place them in an
acceptable rank order, which can then be used as a basis for remuneration system.
Job evaluation, therefore, is simply a technique, designed to assist in development
of new pay structure, by defining relativities between jobs on a consistent and
systematic basis.”
Thus, job evaluation may be defined as a process of determining the relative
worth of jobs ranking and grading them by comparing the duties and
responsibilities, requirements like skill, knowledge of a job with other jobs with a
view to fix compensation payable to the concerned job holder.
Procedure
Job evaluation is an aid to measure the contribution of human resource to the
job and the organization. Proper ground should be prepared to measure the
contributions of human resources and to appraise relative worth of jobs. It is very
difficult for a single man to study, review and evaluate all jobs. Hence, appointment
of a job evaluation committee consisting of technical and non-technical people is
more appropriate.
The next step in the preparation of ground work is analyzing the jobs which
are to be evaluated. Job knowledge can be obtained from the job description and
job specification records. Job knowledge can be gathered and collected through
interviews, observations, activity sampling, questionnaires, critical incidents,
dairies etc.
The next step is identification of compensable factors like knowledge in respect
of education, experience, skill etc. This ground work is more useful for systematic
job evaluation.
18.3.2. Uses of job Evaluation
Job evaluation has certain advantages over other techniques of pay fixation.
They are:
188
1. It is a logical and to a certain extent an objectives method of ranking and
grading the jobs.
2. It helps to fit the newly created jobs in the existing structure.
3. Employee grievances, doubts and complaints would be at the lower level, as it
is a systematic and objective methods of wage fixation.
4. It eliminates some undesirable factors like inequalities in bargaining
capacities of employees and employers, fluctuations in market rates etc.
5. It satisfies the principles of fair wage, wage equity, uniformity in wages etc.
6. It helps to redesign the jobs for minimizing wide wage differentials.
7. It ensures employee satisfaction about wage level and wage equity.
8. It also helps to redesign the jobs by reallocating the easy and difficult tasks
equally among various jobs.
18.3.3. Limitations of Job Evaluation
Though there are certain advantages of job evaluation, it suffers from some
problems. They are:
1. Job evaluation is not exactly scientific
2. Modus operandi of most of the techniques is difficult to understand even to
the supervisors.
3. The factors taken by the programme are not exhaustive.
4. There may be wide fluctuations in compensable factors in view of changes in
technology, values and aspirations of employee etc.
5. Employees, trade union leaders, management and the programme operators
may perceive differently in selecting the compensable factors, in giving
weightages or digress etc.
6. The results of job evaluation may not exactly coincide with social evaluations,
which in turn, result in employee dissatisfaction.
7. Job evaluation is only one among several factors in determining wage level.
Sometimes other factors like government policy may dominate the job
evaluation.
8. It also helps to redesign the jobs by reallocating the easy and difficult tasks
equally among various jobs.
9. Job evaluation programme once structure may not be useful for the next time.
Despite these limitations or problems, job evaluation is the most appropriate
techniques for fixing and revising wage, as it is a system and objectives method of
wage fixation.
18.3.4. Job Evaluation Methods
Ranking Method, Grading Method, Point System, Factor-Comparison Method.
Jobs are evaluated on the basis of various techniques. These techniques are
grouped into two classes viz., conventional and non-conventional techniques.
Conventional techniques are divided into quantitative and non-quantitative
techniques. Non-quantitative techniques include ranking (simple ranking and
paired comparison) and job classification and grading method. Quantitative
189
techniques include point rating and factor comparison method. Non-conventional
methods consist of (i) time-span of discretion theory, (ii) decision making,
(iii) solving compensable factor, (vi) guide line method, (vii) Urwick or profile method
and (viii) profile method.
Conventional Non-Quantitative Techniques or Methods
Conventionally, non-quantitative- simple and crude techniques were
developed. They are ranking and job classification methods.
Ranking Method
a) Simple Ranking: This is the most simplest and administratively the most
easiest technique. The evaluator compares one job with other jobs based on duties,
responsibilities and demands made by the jobs on job incumbent and the degree of
importance of the job to the organization and ranks all the jobs from the most
important to the least important. The evaluator has to appraise and rank the jobs
but not the job incumbents.
b) Ranking the key Jobs: Ranking all the jobs at a stretch under simple
ranking method is difficult. The evaluator, in order to minimize this problem, has to
identify the key or representative jobs at the first stage: rank they key jobs at the
second stage; identify and rank all other jobs at the third stage.
c) Paired Comparison: Another problem of ranking method is that each job
cannot be compared with all other jobs for the purpose of ranking. The method of
paired comparison can be adopted to minimize this problem. Under this paired
comparison method, the evaluator ranks each job in turn against all other jobs to
be appraised, so that a series of paired rankings is produced. This method is more
comprehensive, logical and reliable, compared to the simple ranking method.
d) Single Factor Ranking Method: Another problem in ranking method is
difficulty of operation of the method as ranking has to be done on the basis of
number of factors. In view of this, Goldenberg has suggested a single factor ranking
scheme. The single factor considered is the discretionary contents present in each
job related to other jobs. The single most important task to be performed in a job is
identified and compared within the other jobs. Thus, pure ranking does not cover
these refinements.
The jobs are to be priced after they are ranked. In other words, money value
should be assigned to each job. Key jobs with known monetary values will be used
as the basis to determine the money value of other jobs. Generally there is
agreement about the rates of key jobs.
Advantages
Advantages of this method include- (i) This method is the simplest, quickest
and least costly from the view point of time and money, (ii) it is also appropriate for
ranking the top managerial personnel in large organizations, and (iii) it is useful as
a first and basic step of job evaluation.
190
Disadvantages
Despite the above mentioned advantages, this method suffers from the
following disadvantages- (i) This method provides no yardstick for measuring the
relative worth of one job against the other, (ii)Job requirements, job specifications
and employee specifications are not considered in evaluation. (iii) It does not
indicate the extent or degree to which one job is worthy than the other. (iv) It is not
a comprehensive and systematic technique.
Job Classification and Grading Method
Class and grade are used differently in this method. A grade is a groups of
different skills to perform. A class is a subdivision of a given occupation. For
example, Assistant Accountant, Accountant, Seminar Accountant. The jobs within
a class have fairly similar tasks to be performed, whilst the jobs within a grade may
be different as far as tasks are concerned. However, classes and grades are
designed for the similar jobs and thus receive similar pay. For example, a grade
may consist of jobs like Financial Accountants, Cost Accountants and Management
Accountants and a class may consist of Assistant Financial Accountant, Financial
Account, Senior Financial Accountant and Chief Financial Accountant.
Under this method, jobs at different levels in the organization hierarchy are
divided into various grades, with a clear cut definition of each grade. Grades are
formulated on the basis of nature of tasks. Requirements of skill, knowledge,
responsibilities and authority of various jobs. There are several steps in the
mechanism of this method. The important among them are:
1. Determine the shape and size of organizational structure i.e., tall or flat
organization, geographical or functional organization etc.
2. Preparation of job descriptions
3. Preparation of grade descriptions based on various components.
4. Establishment of a number of job grades and division of the organization into
various grades like Grade- I, Grade-II, Grade- III.
5. Discussion and negotiation with trade union representatives regarding the
number of grades, descriptions, getting their consent, finalizing the number of
grades and grade description and recording them.
6. Selection of key jobs and grading them.
7. Grading the entire jobs.
8. Classifying the jobs of each grade
9. Assigning the money value of the key grades first and then to all other grades.
Advantages
This method enjoys the following advantages:
i) It is simple and easy to understand and operate. (ii) It provides an
opportunity for a systematic organization structure. (iii) Pay grades are better and
appropriate for comparison with those of other organizations. (iv)It is more
elaborate than ranking method.
191
Limitations
i) If sometimes seems to be arbitrary, though it takes the views of the
representative of the trade unions. (ii) Writing grade descriptions is not easy in this
method. However, classification and gradation represent a link in the historical
development of job evaluation between ranking and a points system.
Conventional Quantitative Techniques or Methods
There are two methods under conventional quantitative techniques, viz., points
rating and factor comparison system.
Points Rating Method: This method was introduced by Merrill R. Lott. This was
one of the earliest approaches for evaluating jobs based on quantitative values. This
method is analytical in the sense that jobs are broken into components for
purposes of comparison. This method is quantitative as each component of the job
is assigned a numerical value. Thus, characteristics of factors considered to have a
bearing on all jobs in the programme like skill, knowledge, responsibility, working
conditions etc., are selected under this method. Each factor is divided into degrees
or levels and point value is assigned to each level. The total of point values assigned
to each factor gives the total point values for each job which can be compared.
This method of job evaluation should be developed systematically and applied
methodically in order to avoid the anomalies. The important steps insteps in the
process of developing this techniques are:
1. Constituting a representative committee of members from various
departments for job evaluation.
2. selecting a sample of jobs and preparing job descriptions, job specifications
and employee specifications
3. Selecting and defining those factors which are related to all jobs and are
considered to be most critical in determining the relative degrees of difficulty
and responsibility between jobs. Eight to twelve factors are most desirable.
The following factors may be considered for this purpose.
a) Skill: education, training, judgement, analysis, mental complexity,
mental dexterity, adaptability etc.
b) Effort: Physical demand, visual, effort, concentration, mental effort,
alertness etc.,
c) Responsibility: For preventing monetary loss, machines, materials
safety policy etc.,
d) Job conditions: working conditions, hazards etc.
4. Determining the weight of each factor according to its relative importance.
Assigning the percentage value to each factor. The total percentage of all
factors is 100.
5. Defining each factor, specifying the scope and elements of each factor.
6. Determining relative value of each level within factors. Factors can be
divided into point values by arithmetic or geometric progression.
192
7. Testing the mechanism. Get the total points with the help of above discussed
method for a new sample jobs and compare them with the results obtained
through other methods.
8. Appraise all the jobs and arrive at a composite numerical value for each job.
9. Price the points in order to arrive at the wage level and establish a wage
structure with the help of organisational hierarchy of jobs and salary policy.
There are no hard and fast rules regarding factors, sub-factors assigning the
weightages, deciding upon degrees and values.
This system is only a preliminary step in arriving at an equitable pay
structure. There are no scientific technique to guide in respect of assigning money
value to the points. But various factors like influence of trade unions, pay structure
in comparable industries, financial points system will help in arriving at an
equitable pay structure. The important task in this context is conversion of point
scores into monetary values be assigning a standard unit of money to each point.
money value of various scores can be attained by plotting a graph with points
ratings on the X- axis and money value on the Y- axis. Important one is showing
current salary rates on Y-axis against the score of the job concerned on X-axis.
Trend line through a scatter of points is seen. In case point score is divided among
various grades of jobs in an organisation, the pay level can be related to the grades.
The minimum and maximum pay of each grade are shown in the figures. The pay
scale of various jobs will be fixed within the minimum and maximum limits of the
pay.
This method is superior to other methods discussed so far, as this is analytical
as well as quantitative. The advantages on this method are:
Advantages
1. Almost the same pay scale can be arrived at for the same jobs because
agreement among rates on the same is very close.
2. Definitions are written in applicable terms to jobs.
3. Assigning monetary values is very easy.
4. Prejudice, bias and error of human judgement are minimized in this
technique.
5. Point score or monetary values cannot be manipulated very easily.
6. Assignment of point score or money values is consistent and accurate.
7. Once the score is assigned to a particular job it is long standing.
8. Wage differentials would be systematic and according to the content of the job
under this method.
9. Despite these merits, this technique also suffers from various disadvantages.
Disadvantages
1. It is difficult to determine factor levels and assign point values.
2. It would be somewhat difficult to explain the mechanism and operation of this
method of employees, supervisors and trade union leaders.
193
3. Operation of this method involves heavy expenditure, spending of much time
and clerical work.
However, this technique is superior to the conventional non-quantitative
techniques in several respects. Another conventional quantitative technique is the
point factor or factor comparison method.
The Point Factor or Factor Comparison Method
This method is based both on the principles of points rating and principle of
ranking. This method is analytical as jobs are broken into sub-factors and
components. Under this method, first the components or sub-factors are ranked
under various factor headings. The next step is assigning the monetary values to
the components or sub-factors of each job. Thus, each job is ranked a number of
times (i.e., number of compensable components or sub-factors).
The mechanism or modus operandi of this method involves the following steps:
1. Developing job descriptions, job specifications or job requirements, covering
physical requirements, mental requirements, skill requirements, training and
experience, responsibility and authority working conditions etc.
2. Selecting a number of key jobs. This step is more critical and useful from the
point of evaluation as the other jobs are assigned monetary values based on the
fixed wage rates arrived for the key jobs on the basis for negotiations. A key job
must be clearly divisible into sub-factors and components. This step also
involves dividing the job into sub-factors and components.
3. The third step is ranking of key jobs. The sub-factors of each key job must be
given relative ranks, based on their individual contribution to the total job.
4. The fourth step involves valuing the sub-factors of each of the key job. This
step is also known as factor evaluation. Money worth of each sub-factor of
the key jobs is ascertained in order to know the total money value (or salary)
of each of the key jobs.
5. The fifth step is integrating the monetary value of sub-factors arrived through
factors evaluation with those of ranking of factors. It is to find out whether
the difference among factors as per the ranking and factor evaluation is one
and the same or not. Cross checking is provide where the money value of
each sub-factor is given in brackets.
6. The sixth step is comparing all the jobs (factor by factor) of the same grade of
level with the related key job and establishing monetary value of the sub-
factors of various jobs based on the monetary value of sub-factors or key
jobs. There are certain advantages to this technique over others.
Advantages
1. It is analytical and quantitative method
2. This method is a combination of two techniques i.e., ranking and factor
comparison
3. Since ‘modus operandi’ of this system is relatively easy to understand, it can
be operated and explained to supervisors, employees and trade union leaders.
194
4. This technique is more reliable and valid, compared to other techniques, as
each job is compared with all other jobs from two respects. i.e., factor rank
order and factor comparison.
5. This technique assigns money value more or less fairly and objectively and
there is cross-checking of money value with rank order.
6. However, this technique suffers from certain disadvantages.
Disadvantages
1. It is costly and somewhat difficult to operate compared to the convention
non-quantitative techniques.
2. Factor evaluation in this method is not that such objective as that of point-
rating technique.
3. This technique does not consider all the sub-factors as the operation of the
system would be difficult is it considers all the factors.
Apart from these conventional techniques of job evaluation, there are some
developments in job evaluation techniques in recent years. These techniques will be
discussed under non-conventional techniques.
Market pricing method
In different job evaluation methods like job comparison or ranking method,
grading or job classification method, point rating method and factor comparison
method, points or factors are calculated. After calculating these points, they are to
be converted into monetary value i.e., in terms of rupees. Under the market pricing
method the points/factors are converted on the basis of market factors like demand
and supply. For example, if a particular skills demand is more than the supply
compared to other skills, that particular skill enjoys higher market price and thus
the points of that particular skill is converted at that higher market price compared
to other skills whose supply is more than the demand for the same and ultimately
are quoted at less price in the market. Thus, the jobs with greater demand are
priced at high and consequently higher salaries are fixed for them. And the jobs
with lower demand, lower market price are fixed lower salaries.
Job pricing method
As stated earlier, the points or factors arrived through the methods like
ranking/job comparison, grading/ job classification, point rating and fac tor
comparison are converted into monetary values. These points/ factors are
converted at the price which is fixed on the basis of mental ability, physique,
analytical ability, sharpness, difficulty in carrying out the job etc.
18.3.5 Wage and salary
Wage and salary are often discussed in loose sense, as they are used
interchangeably. But ILO defined the term wage as “the remuneration paid by the
employer for the services of hourly, daily, weekly and fortnightly employees”. It also
means that remuneration paid to production and maintenance or blue collar
employees.
195
The term salary is defined as the remuneration paid to the clerical and
managerial personnel employed on monthly or annual basis.
This distinction between wage and salary does not seem to be vali d in these
days of human resources approach where all employees are treated as human
resources and are viewed at par. Hence, these two terms can be used
interchangeably. As such, the term wage and/or salary can be defined as the direct
remuneration paid to an employee compensating his services to an organization.
Salary is also known as basic pay.
Earnings are the total amount of remuneration received by an employee during
a given period. These include salary (pay) dearness allowance, house rent
allowance, city compensatory allowance, other allowance, overtime payments etc.
Nominal Wage
It is the wage paid or received in monetary terms. It is also known as money wage.
Real Wage
Real wage is the amount of wage arrived after discounting nominal wage by the
living cost. It represents the purchasing power of money wage.
Take home salary
It is the amount of salary left to the employee after making authorized
deductions like contribution to the provident fund, life insurance premium, income
tax and other charges.
Minimum wage
It is the amount of remuneration which could meet the “normal needs of the
average employee regarded as a human being living in a civilized society”. It is
defined as the amount or remuneration. “which may be sufficient to enable a
worker to live in reasonable comfort, having regard to all obligations to which an
average worker would ordinarily be subjected to”.
Statutory minimum wage
It is the amount of remuneration fixed according to the provisions of the
minimum wage Act, 1948.
The need-based minimum wage
It is the amount of remuneration fixed on the basis of norms accepted at the
15th session of the Indian Labour Conference held at New Delhi in July, 1957.
The conference recommended that minimum wages should ensure the
minimum human needs of industrial workers. The norms laid down by it are: (i) in
calculating the minimum wage, the standard working class family should be taken
to comprise three consumption units for one earner, the earnings of women,
children and adolescent being disregarded (ii) minimum food requirements should
be calculated on the basis of a set intake of calories as recommended by
Dr. Aykroyd for an average Indian adult of moderate activity. (iii) Clothing
requirements should be estimated on the basis of per capita consumption of 18
yards per annum which would give for the average worker’s family of four a total of
196
72 yards. (iv) in respect of housing, the rent corresponding to the minimum area
provided for under Government Industrial Housing Scheme should be taken into
consideration in fixing the minimum wage, (v) fuel, lighting and other
miscellaneous, items of expenditure should constitute 20 per cent of the total
minimum wage.
The living wage
According to the committee on fair wages, the living wage is the highest
amount of remuneration and naturally it would include all amenities which a
citizen living in a modern civilized society is entitled to expect, when the economy of
the country is sufficiently advanced and the employer is able to meet the expanding
aspirations of his workers.
The fair wage
Fair wages are equal to that received by workers performing work of equal
skill, difficulty or unpleasantness.
Incentive wage
This is the amount of remuneration paid to a worker over and above the
normal wage as an incentive for employee’s contribution to the increased
production or saving in time or material.
Wage rate
It is the amount of remuneration for a unit of time excluding incentives,
overtime pay etc.
Standard wage rate
It is the amount of wage fixed for a unit of time fixed on the basis of job
evaluation standards.
Need for sound salary administration
Management has to formulate and administer the salary policies on sound
lines as (i) most of the employee’s satisfaction and work performance are based on
pay. (ii) Internal inequalities in pay are more serious to certain employees;
(iii) employees compare their pay with that of other (iv) employees react only to
gross external inequities. (v) employee comparisons of pay are uninfluenced by
levels of aspirations and pay history; and (vi) employees compare the pay of
different employees with their skill, knowledge, performance etc.,
18.3.6. Method of payment of wages
Time wages
Here payment is made on the basis of time. In this system better quality can
be expected. It is easy to understand and also assured of stable income and better
handling of machines and less wastages. But efficient people are not motivated
because there is no incentive. Here planning the output is difficult.
Piece Rate system
This system is adopted by most of the organization, where wage is based on
the performance. This used were the standard of performance is established and
197
measured accurately when completed. Normally a guaranteed minimum is
incorporated under this system.
This provides incentive to the workforce, reduces supervisory burden,
minimizes cost of production enables the organization to estimate cost of
production and spreads the overhead costs over-greater number of products.
But it reflects on the health of workers and condition of machinery. Additional
expenses are to be incurred for keeping extra records. This is not applicable when
group effort is required for the completion of the job. Indirect contributions are
increased wastage, careless handling of machineries and equipments, uncertainty
about wage and decreased morale.
Balance or Debt Method
Under this method, workers are guaranteed time rate with an alternative piece
rate, if the earnings calculated on piece rate exceeds the amount which he ought to
have got, if it is calculated on time rate, he gets credit balance. If the piece rate
equals the time rate, the question of excess payment does not arise. When the piece
rate is less than the time rate worker is paid the time rate and the excess payment
is debited in his accounts. Adjustments are made periodically and balance is paid
to him. This system enables the efficient worker to earn more and also below
average worker is not penalized.
Wage Differentials
1. Occupational differentials
2. Skill differentials
3. Geographical differentials
4. Inter firm differentials
5. Inter industry differentials
6. Differential based (Male/ Female)
Occupation differentials
Occupational differentials are used to motivate young person’s to incur costs
for training themselves and to make them to shoulder higher responsibilities. These
differentials meet the satisfy needs of employees.
Skill differentials
Skilled and unskilled jobs are differentiated, manual and non-manual jobs are
also segregated.
Geographical differentials
Here workers in the same industry and the same occupation living in different
geographical areas are paid different wages. The need for such differentials arise
due to climatic conditions, cost of living, availability of manpower and other factors
peculiar to different geographical segments.
Inter firm differentials
Differences in technological advances, managerial efficiency, capacity to pay
size of the company other advantageous features of the organization are responsible
for disparities in interfirm wage rates.
198
Inter industry differentials
Differential arise because of variable in the work of different industries
Differentials based on sex
These arise due to the inherent capacity difference of male and female. But the
government policy is to give equal pay for equal work but still the difference persist.
Wage differential reflects the physical and mental ability of workers differences
in productivity and labour turnover. At times wages are conditioned by competitive
environment. The level of supervisory skill required also contributes to the
existence of differentials.
Wage incentives
Wage incentive plans reward to employee for his good job-performance. Almost
all commonly employed wage incentive schemes guarantee a minimum wage plus
incentive based upon operator’s performance, if it exceeds a plan wide standard.
Normally, the wage incentive plans should depend on the standards set by work
measurement. The wage rate may be the result of mutual agreement between
employer and employee of formal/ informal evaluation of the employer, operator’s
performance depends upon estimates of standard output.
18.3.7. Requirements of good incentive plan
1. It should be simple, easy to understand and, to operate. It should involve least
clerical work.
2. It would be well planned and guarantee a minimum wage.
3. A worker should be rewarded in proportion to his efforts and achievements
reward should be promptly paid.
4. A worker should get enough and adequate incentive for his contributions.
5. The scheme should preferably be based on time- study data.
6. It should give incentive both for quantity and quality of production.
7. Standards should be fairly set
8. The scheme should be just for workers as well as the management
9. Standards and the allowed time should be altered only when there is a change
in the work method.
10. Standardization should preferably be the basis for all incentive schemes, work
methods, materials, work place, working conditions etc., and all should be
standardized.
11. Worker should be suffer his incentive for reasons beyond his control
12. No limit should be put on a worker’s incentive earnings,
13. The plan should be installed with the consent of the employees.
14. Once installed, the incentive scheme should-be rigidly maintained.
Advantages
1. It helps in the process of pr-determination of labour costs
2. It reduces absenteeism
3. It enhances creativity
199
4. It increase productivity
5. It identifies inefficient workers
6. It reduces need for supervision
7. It provides relaxed environment wherein they can utilize their efficiency fully
for getting maximum emoluments.
8. The burden of proof of individual worth is vested with the employees.
9. It allows possibility of immediate financial reward for initiative and
industriousness.
Disadvantages
1. Quality may be sacrificed in order to increase quantity.
2. It may develop conflict among the workers.
3. It may increase scrap and rejects
4. Impracticable incase of new jobs
5. Affects the health of the workers
6. Feeling of insecurity, emotional strains
7. Delays beyond the control of employees such as power out inadequate in
material supply, failure in the automated system develops strain in their
relationship with managements.
8. Transfers may not be acceptable to them in view of changes in earning
capacity.

PLANT LOCATION
19.1. INTRODUCTION
The location of the plant can have a crucial effect on the profitability of a
project and scope for future expansion. many factors to be considered when
selecting a suitable site
The location of a plant is a major decision and is affected by many factors both
internal and external to the organizations operations. Internal factors include the
technology used, the capacity, the financial posi tion and the work force required.
External factors include the economic, political and social conditions in the various
localities.
19.2 OBJECTIVES
To understand about the various process characteristics and site selection.
To know the principles and different types of plant layout
To find out the uses of maintenance and also compare the breakdown and
preventive maintenance.

19.3.1 Area selection
19.3.2 Community selection
19.3.3 Layout Introduction
19.3.4 Plant layout factors
19.3.5 Types of layout
19.3.6 Maintenance
19.3.1 AREA SELECTION
Area or territory selection calls for the information of a more general nature. In
this initial phase, management is involved in selecting region or general area in
which the plant should be located. The following are the important factors that
influence its selection.
Market
The market is a location of the buyers. It is a factor to be considered in plant
location. Depending on the product, market may be concentrated or widely
dispersed. When a market is concentrated, the market factor lend to influence the
investigator to locate close to this concentration.
For a product servicing a dispersed market the influence of the Market factor
becomes less obvious. It is possible to determine the center market, which is a
statistical device helpful in approximating that point which will provide the lowest
cost for distribution. The center of the market can be used only as a guide for plant
location. The method used to locate a market center is analogous to locatin g the
center of gravity, of a two dimensional object in mechanics.
Locating plant near the markets for this products and services is of primary
importance in a plant location decision. Particularly this factor should be
202
considered if the manufacturing increases the bulk or weight of the product,
renders it more fragile or make it capable of being easily spoiled. Besides, adding
transportation costs, distance adds to transmit time and slows down delivery thus
affecting promptness of service.
If the product is relatively inexpensive and transportation costs (e.g. bricks,
cement) add substantially to the price, a location near the market is desirable. Also
if the product is custom-made, close customer contact is essential. In assembly
type industries many raw materials are gathered together from diverse locations
and assembled into single units. Such industries tend to locate near the market.
Raw materials
The location of raw material is influential in the location problem. Some
industries by the nature of their manufacturing process are forced to locate the
near raw material sources. The steel industry has traditionally located close to the
coal fields since it uses coal in large quantities. However, since new processes have
been developed for basic steel refining which eliminate the need for coal , this
change in the raw material demand could lead to a complete relocation of the steel
industry.
The raw material could be treated in three classes.
1. Pure material which are included in the manufacturing part without loss of
weight.
2. Weight losing materials, only a part of whose weight is represented in the
weight of the finished article.
3. Materials found virtually everywhere.
By assuming uniform rates per distance traveled, which is are
oversimplification, the following generalisation regarding the effect of raw material
on plant location may be made.
1. When a single raw material is used, without loss of weight, locate the plant
at the raw material source, at the market or at any point in between them.
2. When a weight losing material is demanded for the plant, then locate the
plant at the raw material source.
3. When a material found everywhere is used, locate close to market area,
since the material is available everywhere.
Ease of access to suppliers of raw materials, parts, tools, equipment, may be
important. Promptness and regularity of delivery from suppliers and minimization
of freight costs are important.
In general this factor is most likely to be important in transportation of
materials and parts represents the major portion of unit costs and these inputs are
available only in a particular region. If the raw material is bulky and if it is greatly
reduced in bulk by transferring into various products and by-products in
processing, then location near raw material sources is important. If the raw
material is perishable and processing makes it less, then also locating near raw
203
material source is important. If raw material comes from a variety of locations, the
plant may be situated so as to minimize total transportation cost.
In calculating transportation costs, the fact that should be considered is that
these costs are not simply a function of distance but vary depending upon specific
routes and specific product classifications.
Transportation
The problem of transportation is an important factor in plant location. The
movement of material can consume a very high percentage of the final cost to the
customer. One plant location analysis for a specific plant done by an analyst
showed that locating the plant as little as 400 kilometres from the best location
caused loss potential projects of as much as Rs. 30 lakhs per year. This penalty
included higher cost of labour, power and fuel as well as higher transport costs.
The different transportation medium may be listed as follows.
i) Railroads - all classes of traffic,
ii) Water carriers - all classes of traffic
iii) High way vehicle - all classes of traffic.
iv) Pipe lines - Bulk liquid and gases.
v) Aircraft - Where speed is essential and where access by the surface
agencies is difficult.
vi) Pack animals - in different terrain.
vii) Belt, cable or rail conveyers of various types -short distance.
viii) Human carriers - short distance and small quantities.
ix) Electric cable - electric energy.
x) Telecommunications - information commercial negotiations.
Each of the above transportation mediums has its advantages and limitations.
In order to select the proper transportation media, the shipper should consider the
following.
i) Type and extent of material handling facilities at origin and destination.
ii) The relations cost of the various media
iii) The demand for special services, e.g. refrigeration.
Transportation cost vary with the type of route, media and the type of media
selected as well as the length of distance traveled. In general the cost of moving
material per unit distance traveled tapers off as the length of distance traveled
increase.
Adequate transportation facilities are essential for the economic operations of
a production system. The bulk of all freight shipment is made by rail. Rail transport
offers a great deal of flexibility and speed. Most firms required access to railways
which they consider to be essential carriers of their products.
For companies that produce or buy heavy and bulky commodities, water
transportation is an important factor in locating plants.
204
Truck transport is also important particularly for intercity transport.
Availability of pipelines may also influence location. Use of aircraft is expanding
and so the proximity to airports be vital. Travelling expenses of management and
sales personnel should also be considered.
Labour supply and wages
Not only the labour force must be available but also they must contains skills
required in a given manufacturing process.
The history of labour relations in a prospective area for location be studied.
For obvious reasons, it is difficult to secure objective comments from area leaders
and local government officials particularly are promoting their community. The rate
of labour turnover is a good indication of the relationship between management and
labour. A high turnover rate shows up in a high labour cost and it is directly related
to productivity.
The labour force required by a particular industry is predominantly the
location problem takes on some different aspects compared but whose labour force
is predominantly male. Wage levels must also be considered. Wages and skill
available may be lower in a particular and therefore industries requiring many
unskilled workers, which wages are attractive to such regions.
Manpower is one of the most important and costly inputs in production
systems. An ample supply of labour is essential. Firms often the areas in which
there will be more than three or four times of the permanent job applicants
available than the required number. It advantageous to locate in places where there
is diversification industries and business. It is not desirable to have more than his
available work force in manufacturing. The type and level of possessed by the
labour force is important. If company requires particular skills that are not wide
spread, it may have to locate near the particulars areas where these skills are
available. Otherwise, training costs might be more and inadequate productivity
would result. In these cases, labour is desirable but not essential since all the
workers will require some training anyway. It should be noted that a firm can
relocate from a high skill/high cost to a low skill/low cost operation if sufficient
process mechanization is achieved to permit trading off the higher in machinery for
less manpower and lower wages and level of skills.
The existence of regional wage rate differentials may be important particularly
in those cases in which labour cost represents the bulk of total production cost as
in the textile industries. This factor must be considered in light of the skills
available in the area, the size of the labour force, productivity levels, etc., the extent
of unionizations, prevailing labour- management attitudes history of labour
relations turnover rates, absenteeism. etc, should also be considered.
Climate and fuel
Climate greatly influences human efficiency and behaviour. A plant whose
production process require a constant temperature of 20°C find no such situation.
205
It should be located on a site that has a temperature of 20°C and standard
deviation of 5. This will call for least amount of artificial heating and cooling.
Heating engineers can compute heating costs on the basis of temperature
data. In addition to fuel costs, climate can influence selection of a territory because
of the amount of precipitation or pollution. Wind velocity and direction can also
influence plant location these become very important factors when the possibility of
radioactive fallout resulting from an attack upon a distant city is considered.
Location of other plants and warehouses
Firms always try to place new plants where they will complement sister plants
and warehouses and minimize total cost. They look market needs and supply and
demand disparities and locate where in markets have been served by long distance
travels. The location competitors plants and warehouses must also be considered,
the object being to obtain an advantage in both freight costs and the level customer
service.
19.3.2 Community selection
Once the general territory for location has been selected, it becomes necessary
to choose a community and a site. A decision must be made regarding the size of
the community in which the plant is to be locate the alternative choices can be
classified as
1) City location
2) Suburban location
3) Country location
City Vs Suburban Vs Country
The advent of the automobile has brought new mobility to the working force.
This is one of the reasons for the present day industrial rush to the country. Wide -
open spaces and freedom to expand are probably two of the biggest inducements.
The type of manufacturing process may dictate the site relation. For example,
a country location is desirable for a plant producing explosives some of the general
conditions leading to the selection of an appropriate type of community might be
listed as follows:
A) Conditions suggesting a city location
i) Large skilled labour required
ii) Process heavily dependent upon availability of city utilities
iii) Multi floor building desirable
iv) Close contact with suppliers is demanded
v) Rapid public transportation is available.
B) Conditions suggesting a suburban location
i) Semiskilled labour force required
ii) Avoidance of heavy city taxes and insurance desired
iii) Labour force residing close to the plant
206
iv) Plant expansion is easier than in city
v) Community close to but not in large population center
c) Conditions suggesting a country location
i) Large site required for either present demand or expansions
ii) Lowest property taxes available desired
iii) Unskilled labour force required
iv) Low wages required to meet competition
v) Morale of working force improved by country location
vi) Manufacturing process is dangerous or objectionable
The choice of the community depends upon the region already chosen Most
community selection factors cannot be quantified and can e evaluated subjectively.
Managerial preferences
This often plays an important role in plant location decision. Many due to
community ties companies will not relocate. When firms locate the location
selection in some cases is heavily influenced by preferences of the managers who
will be transferred.
Community facilities
This involves such factors as quality of life, which in turn is a function of the
availability of such facilities as schools, churches, medical services, police and fire
protection, cultural, social and recreational opportunities, having good streets and
highways. Also important are the communication facilities and the range frequency
and reliability of transportation facilities.
Community attitudes
Community attitude is an another factor to be considered in location the plant.
The cultural, social and educational community atmosphere is being given more
attention by plant location investing a since management has recognised that these
aspects are often important to key employees.
The political climate of a community might well be investigation the tendency
of government bodies to encroach on the privilege business has caused
management to carefully study the political climate in a prospective location. The
back issues of the local newspaper a period of time can level such aspects.
These can be difficult to evaluate. Unless the industry is for so reason of an
offensive nature, most communities welcome new industries However, the
formation of anti-industrial pressure groups or a lack co-operation, interest and
enthusiasm on the part of community can result in poor relation between the
relocating firm and local government labour and the general public.
Community, government laws and taxation
State and local laws should be studied when considering various location.
Labour laws, workmen's compensation laws, etc., vary widely from one location to
another.
207
Some of the aspects of industrial operation regulated by law hours of work,
minimum wages and working conditions for women employees. The respective laws
should be investigated which penalize certain types of industry in certain areas.
Waste disposal smoke reduction and nuisance regulations should be studied for the
various alternative locations.
Some industrial concerns pay excessive taxes. Taxes should considered in
selecting a site but a plant location analysis says that incentives are relatively
unimportant secondary factor of location. Given the governing factor, the tax
incentive may induce a specific local within the area defined by the basic factor. If
the location offering incentives is not within the area set by the governing factor it is
simple not considered.
Stable, honest and co-operation of government officials are important asset as
most of the local legislations affecting industry under their control. Restricting,
unreasonable local ordinary concerning building codes, zoning, pollution control
etc., can seriously inhibit operations.
Tax rates are important but must be considered in terms of service provided.
There should be some attempt to forecast these charges, future expansion of
community services and facilities is likely, taxes probably increase.
Financial Inducements
Many central and state governments offer subsidy and financial inducements
to companies to influence them to build plants in their areas. Government may
provide loans for plants for newly established plants within their regions. However,
the companies should not allow temporary inducements to overshadow the basic
merits of any location.
Profile of present Industry
The kinds and quality of industrial concerns already in the community area
also pertinent factory to be considered in plant location.
Site Selection
This is the final stage in the plant location analysis.
One thumb rule regarding the size of a site is that it be not less than five times
the actual size of the plant itself. This is considered a minimum in order to allow for
loading platform, siding, transport access, parking facilities and storage area.
Wherever possible, open land is desirable or two or more sides to allow for future
expansion.
Unfortunately, tempting offers of a fine site or attractive tax frequently
influences plant location decision. Objective data is essential to good plant location.
Researchers in plant location says, that in order to properly select a list of
general specification should be as follows.
i) Description of the building to be constructed including the sketch.
ii) Size of the plot.
208
iii) Necessary railroad, highway and waterway facilities.
iv) Minimum size of water main, gas line and power line.
v) Volume of ground water to be utilized.
vi) Sewage and effluent disposal requirements.
vii) Safety area for offensive odours, noise, smoke, etc.
viii) Provisions for sprinkler pressure (ground tank or local water main)
The maps published by the Geographical Survey are useful in electing a good
plant site. These maps show the land elevations, water feature, dams, buildings,
railroads and power lines. When choosing a site the following factors should be
investigated.
Topography
The topography, soil mixture and drainage must be suited to the type of
building required and must be capable of providing with a proper foundation. If
considerable land improvement is required, low-priced land may turn to be
expensive.
Utilities
The cost, adequacy and reliability of the supply of power and water must be
evaluated.
Power
All Industries today require electric power of some sort. In addition there are
certain industrial processes that require large amount of electric power. For
example the refining of Aluminium require cheap electricity in large amounts and
for this reason Aluminium processing plants are located in areas where large
sources of inexpensive power is available.
In a situation where a large amount of steam is utilised for processing or
heating it is sometimes advisable to use this steam for power generation purpose.
The following check list may be helpful when examining the power situation in
a given area.
i) Type of service
a) Hydro - electric
b) Steam
c) Other
ii) Reliability of service - history of stoppages,
iii) Adequacy of supply - seasonal restriction.
iv) Kind
a) phase
b) cycle
c) voltage
v) Rates
209
vi) Availability of off peak contracts.
vii) Fuel adjustment.
viii) Lighting allowances
ix) Discounts and penalties.
Hydro-electric power Is usually associated with cheap rates, although the
original installation of the hydro electric plant considerably more costly than that of
steam plant. Technical developments leads to constant improvement in power
generation and
Water
There are certain industrial processes which requiring large of water. Selecting
a site with a good water supply is essential in steel, paper board, paper pulp, food
and chemical processes.
Water is generally available from three sources,
(i) surface - water from lakes, streams, etc.,
(ii) ground - springs and wells and
(iii) rain water
Surface water varies greatly in its chemical analysis and microscopic and
vegetation may add taste and colour harmful to specific manufacturing processes.
Hard water can damage steam boilers, pumps and circulating systems, engines and
other water jacket equipment. The PH factor is the measure of hydrogen ion
concentration of water and it expression of its acidity or alkalinity. This factor
should be checked tress affect the manufacturing process.
The cost of the supply of power and water are sizeable and constantly
recurring costs. Accurate cost determination requires contact with the local utility
company. Use restrictions may be imposed and may be wide variations in
availability. The water supply must be sufficient to meet peak needs and
compensate for dry spells. If water is poor quality it may require chemical treatment
or purification. The cost of connecting these services to the plant must not be
overloaded. Sometimes it can be done only at high costs.
Waste disposal
This must be considered when selecting the site. The plant should it be
positioned so that prevailing winds carry any fumes from populated areas and so
that waste may be disposed of properly and at reasonable expense.
Waste disposal is getting to be more and more of a problem as industrial
concentration built up. As the radioactive materials finding industry in increasing
numbers, the problem of disposal of radioactive waste has become quite critical.
Enterprising businessman heavily industrialized area might establish profitable
business of collecting and disposing of radioactive wastes from the industries.
210
Transportation facilities
Railroads and highways should be close by in order to minimize the cost of rail
lines and access roads. There must be enough through highways and railroads to
serve the community itself. Special requirements for water or air transport must be
considered. The plant itself should be easily accessible by car or preferably public
transport.
Intangible factors to consider include the dependability and character of the
available carriers, frequency of service and freight and terminal facilities. Cost and
time required to transport the finished product to market and the time required to
contact or service a customer must also be considered.
Land costs
These are generally of minor importance as they are non-recurring and make
up a relatively small proportion of the total cost of locating a new plant.
It should be emphasized that plant location analysis is a periodic task. The
world is rapidly changing and the management should not, expect a location to
remain optimal forever. Every organization should periodically reassess its
environment whether any long term changes have occurred that may make it
advantageous for the organization to alter or possibly relocate some portion of its
facilities.
19.3.3. Layout
Plant layout is the integrating phase of the design of a production system. The
basic objective of layout is to develop a production system that meets requirements
of capacity and quality in the most economical way. The specification of what to
make (drawings and specifications), how it is to be made (route sheets and
operation sheets) and how many like (forecasts, orders or contracts) become the
basis for developing integrated system of production. This integrated system must
provide for machines, workplaces and storage in the capacities required so that
feasible schedules can be determined for the various parts and products. The
system should also provide a transportation system which moves parts and
products through the system. It should provide auxiliary services for production
such as tool cribs and maintenance shops and for personnel such as medical
facilities and cafeterias.
Principles of a good layout
An optimum plant layout is one which provides maximum satisfaction to all
parties concerned; that is the employees and management as well as the stock
holders. Each of the parties involved has certain interest in obtaining a good plant
layout. Keeping these interest in mind the major principles of a good layout are:
1. provide over all simplifications
2. minimise cost of materials handling
3. provide high work-in-process turnover
4. provide effective space utilization
211
5. provide for worker convenience and promote job satisfaction and safety
6. avoid unnecessary capital investment
7. stimulate effective labour utilisation
Simplify the production process
This is the broadest objective in obtaining a good layout. A good layout should
be planned to facilitate the over-all manufacturing process so that it can be carried
on in an optimum manner. More specifically, simplification may come from the
following:
a) Equipment should be arranged to provide greater utilisation. Equipment
involving high capital inventory should be located so that it can be
conveniently used on a multiple- shift basis. Material handling equipment,
like conveyors should be located so that a group of products can utilise it
conveniently.
b) A good layout will minimize production delays and reduce congestion,
production delays may be reduced or eliminated by good line balancing.
Provision of proper amount of storage space reduces congestion on the
floor.
c) Good plant layout allows for the needs of maintenance of equipment.
Equipment must be located so that routine maintenance is easy to
perform. Good layout calls for prediction of future maintenance problems.
d) Increasing output or shortening manufacturing time can be provided in an
improved layout. Increased output means greater output with the same or
less cost, saves the man hours and reduce machine hours. Manufacturing
time can be reduced by eliminating idle time and removing unnecessary
storages.
Minimizing Materials Handling
In a plant the production machines should be arranged such that the
materials pass directly from one machine to the another. Material handling is
brought to a minimum by this arrangement of machines. In many situations
manual material handling is most economical. Even in this situation reducing the
distances required for manual material handling should be considered when
planning.
Providing high work-in-process turnover
Every day material remains in the plant and adds cost to the product because
of the tied-up capital investment. In the process industries, for example, in
petroleum refineries where the product is in the liquid state, work-in-process
turnover is high and unnecessary in-process stages are reduced to a minimum.
When the product is in the solid state, it is much more likely to involve a high
capital investment in work-:in-process. Although this is primarily a production
control problem, good layout can be helpful in reducing work-in-process.
212
Effective space utilisation
Making good use of space involves considering not only production and storage
areas, but also the floor area required by service departments. Stock bins spread
out on only one level, idle aisles, and unorganised storage areas are all lead to poor
space utilisation. The cost of floor space varies from one location to another location
but considerable thought have to be given for accurately calculating floor area cost.
Worker convenience and Job satisfaction
Workers want to work in a convenient environment. Providing the worker with
a place to leave his tools and with easy access to materials storage, reducing
excessive noise with sound- deadening walls, as well as considering his safety are
factors that should be examined when planning a layout. Attention to such items as
heat, ventilation, light and removal of moisture and dirt is important in promoting
worker's job satisfaction. Layout that calls for unstable stacking of materials should
be changed to correct safety hazards. The layout engineer should keep close contact
with the safety engineer in order to assure that safety has been thoroughly
considered in a given layout.
Unnecessary capital investment
Capital investment in equipment can sometimes be reduced by the proper
arrangement of machines and departments by conveniently locating a particular
piece of equipment two different parts, both requiring part-time use of a broach,
may be routed through the same broach. Thus the cost of a second machine is
avoided. During the process planning phase capital investment can be minimized
by making use of idle time on previously owned equipment. This type of problem is
primarily one of the production scheduling, but by being aware of the problem the
layout man can facilitate production scheduling by installing a good layout.
Labour utilisation
Every year so many productive man-hours are wasted because of poor layout.
Proper layout does not guarantee but certainly stimulates the effective utilisation of
man power. The following suggestions should be considered in making effective
utilisation of labour.
a) Direct labour utilisation: Improper layout can make the production;
extremely wasteful. Making it necessary for the production worker walk
great distances to obtain tools or materials can waste a number of man
hours. Good methods engineering and line balancing can minimise worker
idle time.
b) Indirect labour utilisation: Building design to provide ease of maintenance
can save many rupees per year. Proper design of ailes can result in better
utilisation of fork-lift operator.
c) Better supervision: A supervisor should theoretically be in contact with his
department at all times. An enclosed office should be provided for a
foreman with direct line authority. This is essential when a foreman finds
it necessary to discipline a subordinate.
213
19.3.4. Plant Layout Factors
Every one with in an industrial organisation is concerned with plant layout in
some way and everyone within a plant is interested in its layout to some degree.
The worker is interested in the arrangement of his work station. The foreman is
interested in layout as it affects the output of his department. Middle management
is interested in layout as it affects the output and costs. Suggestions that result in
plant layout thinking may come from anyone in the organisation from the director
to the production worker.
Most plant layout decisions are stimulated by one of the following factors.
a) product-design change
b) new product
c) change in volume of demand
d) facilities becoming obsolete
e) frequent accidents
f) poor working environment
g) change in the location or concentration of markets
h) cost reduction
Product-design changes
Automobile models are radically changed frequently which usually require a
change in plant layout. A full time plant layout department is essential in an
automobile industry. In industries manufacturing a more stabilised product, plant
layout may not be a crucial problem. These concerns must solve the plant layout
problems whenever a product change comes even though it may occur infrequently.
New product
The addition of a new product as well as the dropping of an old one is a
development which results in thinking about the plant layout problem. Progressive
companies are continually on the alert for new product developments. Research
and development departments are continually providing new products for the
industrial or home consumer. As these products come to the production -planning
stage plant layout should be integrated with the planning of the production
processes.
Changes in the volume of demand
An increased demand for a product may result in the revision of a present
plant layout. It may result in the planning of a completely new plant. A decreased
demand for a product may also result in plant layout changes.
Facilities becoming obsolete
Plant layout problems are often created by the obsolescence of industrial
equipment, processes and buildings. Equipment replacement results in only minor
changes in a present layout. On the other hand, when an industrial process
becomes obsolete, changes in plant layout are usually demanded. Buildings that
become obsolete, whether because of size limitations or some other reason, may
214
result in plant expansion of present building, the building of a new plant or a move
into a new building Any one of these alternatives involve considerable plant layout
work.
Frequent accidents
Hazards to safety must be foreseen while designing good plant layout Where
electric welding is a part of an industrial process, shields or screen must be
provided around the arc-welding production centers in order to prevent injury to
the eyes of personnel in surrounding areas. Aisles should be designed so as to
minimise the possibility of accidents caused by materials handling equipment.
Poor working environment
Worker complaints regarding working conditions such as noise or changes in
temperature, may be resolved by changes in plant layout. Providing the worker with
easy accessibility to materials, tools and instructions are considered in good plant
layout. A layout which considers these factors helps to establish the reputation of a
firm as a good place to work.
Change in the location or concentration of markets
Changes of market locations lead not only to plant layout problems but often
make plant location studies necessary. Often the planning of a completely new
plant is the answer to changes in market location.
Cost reduction
Cost reduction is a general term indicating management's device to reduce any
one of the numerous costs involved in operating an industry. Since the time of the
Industrial Revolution it has been one of cost vital of all the considerations in
manufacturing industries. It must continue to have top priority if productivity
curves are to continue upward.
Costs can be reduced in many ways. New materials develop which can be
substituted for expensive materials. The development of a faster production process
can reduce the inventory tied-up in work-in process inventory. Improved layout is
synonymous with improved methods. In addition, improved plant layout can result
in the reduction of cost brought by better utilisation of buildings, tools and
equipment. With automatic factory on its way, the costs of maintenance will rise
rapidly compared to the costs of production. Proper layout can facilitate
maintenance procedures and thereby achieve cost reductions.
Basic types of layout
Layout choices must closely tied to higher level decisions. Several fundamental
strategic choices must be made in layout planning.
Determining what to move
Productions consist of combining and manipulating men, materials and
machines. These elements may be combined in various ways during production
activity. The proportion in which these elements will be used depends on their
relative cost and on the production process selected before laying out a plant it is
215
necessary to determine which of the elements are to be fixed and which will be
mobile during the process a production. Various alternatives are available in
determining which factor to move.
a) to move the product and worker from one workstation another workstation
b) to move the product from one workstation to and workstation, keeping
machine and worker stationary
c) to move the worker and the machine to the product which held at one
location
The decision as to which arrangement to employ depends on relative mobility
of each factor in plant and on the comparative cost each method.
The first method that is moving both product and worker from machine to
machine is not very common in modem production. It employed in some job-lot
production plants turning out custom – made products, worker moves with his
work from machine to machine usually operating a limited variety of machines.
The second method is common in the manufacture of standardised products.
Product moves through machine work stations and continuous process equipment
which are fixed to locations and attended by work Example is the flow of materials
in any automobile manufacture.
In the third arrangement the worker and the machines are brought to the
materials. Manufacturing operations producing bulky products as steam turbines,
boilers, generators, locomotives and ships.
Fabricated and assembly of smaller parts are usually carried out the first and
second arrangement. There are many instances where the machining of large
castings and other parts of the product is done portable machine tools which are
brought to the product. In most manufacturing concerns producing standard
products and custom made products employs the first two alternatives.
19.3.5 Types of Layout
This is designed for the non-repetitive, intermittent types of production where
special orders are handled. In process grouping similar processes or equipment are
grouped together. When strategy calls for focus, resources (employees and
equipment) must be organised the around process. A process layout accomplishes
this purpose by clustering in one center the resources that perform similar
functions. For example all grinding is done in a grinding department, all bills are
processed in the same area of a shop and all bills are processed in an accounts
payable section. This format is most commonly used when many different products
(customers) must be produced or served intermittently at the same work stations.
Demand levels are too low or unpredi table to allow human and capital resources to
be set aside exclusively for a particular product line or type of customer. Resources
relatively general purpose, flexible and less capital intensive. The process layout is
less vulnerable to changes in product mix or new marketing strategies. Employee
supervision can be more specialised which is important when the job con tent
requires a good deal of technical knowledge.
216
PROCESS LAYOUT
Advantages of process layout
(i) Lower capital investment
Less capital is needed because production machines will utilised to greater
capacity. Machine can be kept operation most of the time. Equipment is highly
productive.
(ii) Wide flexibility in production facilities
Greater variety of jobs can be handled on a comparative small investments
because of utilisation of various types general purpose equipment. Each machine
can perform a wide range of similar kinds of operations. Moreover there is flexibility
in planning production. Jobs are scheduled for a department as a whole. So it is
possible to assign work to any available machine in the given department.
(iii) Effective supervision readily achieved
Each foreman supervises only a limited range of machine operations like
foreman over welding and grinding. Because task for each foreman is not too
diverse, he becomes highly proficient in time and with practice. He is able to direct
the setup and performance of every kind of operation done on the equipment. He
also becomes expert in maintenance and repair of equipment, inspection
requirement and planning production control of his department.
(iv) Machine failures do not seriously disrupt production schedules
Industrial machine break-downs do not hold up subsequent operations. If
there is break-down in one machine in department the work can be easily
transferred to machine in the same department.
Disadvantages of process layout
(i) More material handling
There will be no definite channels through which all the work will flow. Work
in-process, may return to the same department more than once for processing and
this makes back tracking of work making higher cost of materials handling.
(ii) Greater total floor area required
A greater proportion of the floor space is required for service activities which
result in a lower proportion of total plant area being devoted to actual production
activities. There is greater need for aisles, temporary storage at each department.
All of these need more floor space per unit of product turned out.
(iii) Higher skilled labour and difficulty in labour procurement
Workers must be skilled because they operate a number of general purpose
machines doing a variety of jobs. More highly skilled labour is required and wage
rates will be usually higher. Further there may be difficulty in procuring such
labour on short notice.
(iv) Need for more frequent inspection
Inspection is generally necessary before the work goes to the next operation in
another department. Strict departmental responsibility for quality of work turned
217
out is the main reason for the need of inspection in each department. Subsequent
rejection of material by another department causes a considerable amount of
handling, confusion and rerouting to rework the faulty part.
(v) Longer processing times
Total time needed for processing production orders under process layout is
greater than that required in product layout. More time is consumed because work
necessary for loading the machines must be delivered to each department and after
processing work is to be held for inspection. More over large amount of material s
handling is necessary between departments. It is difficult to co-ordinate material
handling because personnel cannot always be made available to move when it is
released from a department. The end result is longer period of processing time.
Process layout is suitable for intermittent production. It is employed - the
same facilities are used to fabricate and assemble a wide variety of parts when part
and product designs are not stable. From historical of view process layout preceded
product layout. Any considerable growth in demand for product of any industry
gradually makes advisable aversion of layout in part or whole from process to
product. A gradual transition from process to product layout may take place as and
increases for products. Product layout is introduced first either arts of fabricating
activities or in assembly operations. The complete product layout arrangement is
finally introduced to whole production process.
PRODUCT LAYOUT
Equipment needed to fabricate or assemble the product is brought together
and setup in accordance with the required sequence operations. Material flows
through predetermined channels of operations from the receipt of raw materials to
fabrication of various component parts to final assembly, layout is designed for the
flow type of production where continuous or repetitive operations are carried on to
produce large quantities standardised product. Under product grouping all the
machines needed to produce part or sub assembly are arranged sequentially
continuous line in the order in which the successive operations product must be
performed. The part flows from machine to machine-moving a short distance at a
time until all required operations completed. This arrangement results in
processing of the product forward flow from the receipt of raw materials to
shipment of finished product. Straight line production has been adopted in
numerous continuous process industries such as sugar refineries, cement plants,
automobiles etc. In recent years many other industries have recognised the
advantages to be gained by adopting line production methods.
Advantages of product layout
1. Channelised flow of work reduces materials handling: Definite and direct
channels for the flow of materials, short distances between operations elimination
of backtracking and mechanisation of handling are features of product layout.
These reduces materials handling cost.
218
2. Low cost labour and easy in procurement and training: Because of the
use of special purpose automatic or semi-automatic machine's and elaborated
tooling product layout an effectively utilise low - cost unskilled and semiskilled
labour.
3. Less inspection required: A limited amount of inspection at the end or at
some critical in the line is usually sufficient.
4. Floor area more productive: Minimum aisles. General absence of large
banks of, temporary storage and numerous inspection. There is less need for
movement of quantities to centre and temporary storage.
5. Short processing time: Intermediate activities between machine operations
such as travel, storage and inspection occurs less frequently. Therefore,
opportunities for delays will be reduced. Hence, the total time for processing
product is shortened.
6. Simplicity and easy production control: As long as changes in design of
product are held to a minimum and operations are standardised engineering and
production planning activities is largely limited to initial program necessary to
establish production. At the beginning it is necessary to prepare drawings, list of
parts, materials requirement, routing procedures and so on. This simplifies
production planning and control problem.
Disadvantages of Product Layout
1. Higher initial investment
In product layout frequently at various work centers more than sufficient
capacity will exist. This condition result in an unavoidable duplication of facilities
and increases the investment required for product layout.
2. Production line shut down will occur
If a machine fails under product layout there is a shutdown of production.
Shut down of line can also be caused by a miner shortages of material, employee
absenteeism or poor production
3. Supervision more difficult
Line is a collection of numerous kinds of machine requiring wide range of
knowledge on the part of supervisor Foreman's job involves supervision of diverse
activities because each machine requires a knowledge of various setups, kin of
operations and operating feeds. He is also responsible for the quality control of
many kinds of jobs being simultaneously processed. He must be also familiar with
maintenance requirements of his equipment.
4. Inflexibility of facility
Equipment under product layout consists of facilities designed to perform
special operations. Usually no machine unit of the line is exactly interchangeable in
capacity, kind of work performed with any other unit. This characteristic of strict
product layout results in inflexibility of facilities makes for interruption, costly
change over or makes replacement design changes are made.
219
HYBRID LAYOUT
More often a positioning strategy combines elements of both product and
process focus. This is an intermediate positioning strategy which calls for a hybrid
layout. Some portions of the facility designed as a process layout and other portions
are designed as product layout. This treatment is often applied when group
technology cells, one-worker-multiple-machine stations, or flexible manufacturing
systems are introduced. These "islands of automation" represent miniature product
layouts, since all resources needed to make the family of parts are together as one
center. At the same time, not all production can be handled this way and the rest of
the facility represents a process layout. Hybrid layouts also are found when
facilities have both fabrication and assembly operations. Fabrication operations,
where components made from raw materials, tend to have a process focus. As
operations tend to have a product focus.
Another example of a hybrid layout is a retail store, merchandise may be grouped so
that customers have a fairly good of where to find desired items (a process layout). At the
same customers often are routed along fairly predetermined paths layout. The motive is to
maximise exposure to the full array of thereby stimulating sales.
FIXED POSITION LAYOUT
The fourth basic type of layout is the fixed-position layout a product is
particularly massive or bulky it does not make move it from one work station to
another as with process, product hybrid layouts. Such is the case in shipbuilding,
assembling airplanes or making huge pressure vessels, building dams or repairing
home furnaces. Workers, along with their tools and equipment, come to the product
to work on it until it is finished, or at least until much of work is completed. This
layout type minimizes the number of times that the product must be moved and
often is the only feasible solution.
19.3.6. Maintenance
Efficient use of plant and equipment is a vital factor for the industrial growth,
particularly in a developing country like ours. Plant and equipments besides being
very expensive, are in many cases imported involving valuable foreign exchange.
Further the cost of plant and equipment forms a considerable portion of the total
cost production. Thus' it is imperative to look after them as careful, possible. Plant
maintenance is of great importance as it provides a means to maintain the plant
and equipment in a high state of operating efficiency and enhance its productivity.
Generally in Indian industries the utilization of plant and equipment needs to
be considerably improved. While there may be many reasons for under utilization,
downtime due to unscheduled breakdowns and stoppages is one of the primary
causes. It is necessary to increase the working life of the existing plant and increase
the utilization. Efficient utilization of plant becomes extremely important in order
that the capital resources are available for expansion schemes rather than
replacement of equipment which in turn will help industrial development.
220
Poor maintenance causes economical loses such as:
1. Increased downtime
2. Poor efficiency
3. Deterioration of equipment
4. Poor quality of product
5. Higher labour costs
6. Loss of material in, process
7. Higher production costs
8. Increased hazards etc.
Systematic maintenance procedure offers tremendous possibilities for saving
in money, materials and manpower. These savings come through
1. Reduction in downtime
2. Reduced losses of material in process
3. Increased life of the equipment
4. Reduction in overtime
5. Optimum spares inventory
6. Timely replacement of spares and machines
7. Maintenance of product quality
8. Proper running of equipment
9. Optimum operational cost of the machines
Through proper maintenance the downtime of equipment comes down
considerably. Machines are attended to before they breakdown. Spare parts are
replaced before they fail. Lubrication is done regularly and according to a timetable.
All these and many other activities keep the equipment in good running condition.
Whenever the equipment breakdown, particularly in a chemical plant the
materials in process, which are all inside the various types of equipment,
undergoing some reaction or the other get spoiled. Often these materials need to be
flushed and drained before starting the plant again. The losses due to this wastage
can be substantial if the materials being treated are expensive. Rayon plant is one
such example. If the raw materials are imported it will be still worse and hence
such losses are to be reduced, which is possible through proper maintenance.
In India the cost of plant and machinery is quite high and many sophisticated
equipments are still imported. Replacements are not easy. Capital is scarce. Hence
the installed equipment should be kept in good working order as long/as possible
and its life must be prolonged to the extent possible, proper maintenance, timely
replacement of parts, modifications to suit the conditions of operation etc., help to
enhance the life of the equipment.
Good maintenance leads to higher output through lower downtime of plant
and equipment, better quality of products through improved efficiency and l ower
unit costs through reduced breakdown expenses. Plant and equipment deteriorate
with use. If the deterioration is not checked they will not function and will become
221
unserviceable. Maintenance primarily aims at keeping the plant and equipment in
efficient operating conditions, minimizing the downtime, as to ensure their
maximum availability for production.
Broadly, the objectives of a systematic maintenance scheme are, to safeguard
the investment, to keep the equipments in good working condition, to prol ong the
life of the equipment and to assure optimum availability.
TYPES OF MAINTENANCE
Maintenance practices can be broadly classified into following two types:
1. Breakdown maintenance
2. Preventive maintenance
Break-down maintenance
In the case of breakdown maintenance the equipment is generally attended
only when it breaks down. The maintenance crew will carry out the necessary
repairs, when the machine has actually broken down and is not able to function, in
order to put it back into commission. Such breakdowns may occur to any machine
at any time. There are many disadvantages in this system. Some of them are:
i) There is always an urgency to put the machine back in the working
condition and hence the machine may not get adequate maintenance.
ii) Since the type and time of breakdown is uncertain, production plans get
completely disrupted.
iii) Planning of maintenance work is not possible.
iv) Distribution of workload is difficult.
v) Results in unbalanced utilization of maintenance staff.
vi) May result in overstaffing the maintenance department.
vii) Increased overtime.
viii) Increased downtime of equipment due to non-availability of man-power.
ix) Excessive inventory of spares.
x) Waste of materials in process in continuous chemical Industries.
xi) Poor working conditions for maintenance staff.
However, breakdown maintenance system may be suitable in certain
conditions such as
i) Where plant capacity exceeds market demand.
ii) Standbys are available and quick switching over is possible
iii) Process is obsolete and more modern equipment is under consideration.
iv) May be economical for non-critical equipment where this type of
maintenance is cheaper than any other system.
Normally, breakdown maintenance system is not recommended in a general
practice since it has many disadvantages and this system of maintenance is now
being gradually replaced by more systematic type maintenance.
222
Preventive maintenance
As the name itself indicates preventive maintenance is based on the old adage
"Prevention is better than cure" or "a stitch in time saves nine". Preventive
maintenance is a systematic maintenance procedure where-in the condition of the
plant is constantly watched through a systematic inspection and preventive action
is taken to reduce the incidence of breakdowns. The necessity for either major or
minor repairs is determined, to prevent unexpected interruptions to the plant and
equipment or any deterioration.
The fundamental activities of preventive maintenance are:
a) Periodical inspection of plant and equipment to discover conditions of
deterioration
b) upkeep of equipment to remove or repair such conditions while they are
still in a minor stage.
Thus the essence of the preventive maintenance is a well planned inspection
system. Proper inspection at the right time is the crux of the preventive
maintenance system. The results of inspection are used to analyze the problems of
upkeep, replacement and modification well in advance and thereby help proper
planning and assessment of the work contents of the jobs. It is of course necessary
to determine with great care what is to be inspected and when. Meticulous
recording of the facts revealed during such inspections is another important point.
Analysis of such records indicate the type of maintenance work needed,
replacements required, planning of maintenance work and inventory of spares.
Preventive maintenance renders more effective use of manpower and material and
helps to attain greater efficiency in plant operation. Planning of maintenance work
and optimum inventory of spares and components, become possible with the
introduction of this system. It will be possible to synchronize the maintenance
program so that there is least interruption to continuous operation and production.
As against breakdown maintenance where plant equipment gets the attention
only when they breakdown, preventive maintenance is a planned and systematic
procedure which takes a continuous care of the equipment, mending and repairing
as and when required to minimize breakdowns and unscheduled stoppages,
resulting in various advantages and savings.
However, certain limitations of preventive maintenance are, that during initial
stages of its introduction, it may appear to be expensive, although in the long run it
is highly beneficial. The procedure and the frequency of inspection would have to be
carefully worked out and improved over a period of time. The data for preventive
maintenance will have to be built up gradually and the system has to be refined
depending on the data collected.
The various elements of a preventive maintenance system in an industry are
as follows:
1. An inventory of all the plant and equipment that need to be maintained.
223
2. Categorization of equipments to assess the relative importance and thereby
determine the equipments requiring preventive maintenance.
3. A well designed inspection system.
4. A good lubrication system.
5. Maintenance of adequate records and analysis of these records.
6. Planning of maintenance work.
7. Control of maintenance stores and spares.
8. Organization for preventive maintenance work.
PREVENTIVE VERSUS BREAK-DOWN MAINTENANCE
Quality control procedures are designed to track characteristics of quality and
to take action to maintain quality within limits. In some instances the action called
for may be equipment maintenance. The maintenance function then acts in a
supporting role to equipment operating effectively to maintain quality standards, as
well as to maintain the quantitative and cost standards of output.
There are alternate policies that may be appropriate, depending on the
situation and the relative costs. First, is routine preventive maintenance
economical, or will it be less costly to wait for breakdowns to occur and repair the
equipment? Are there guidelines that may indicate when preventive is likely to be
economical? What service level is appropriate when breakdowns do occur? How
large should maintenance crews be to balance the costs of downtime versus the
crew costs? In addition there are long range decisions regarding the possible
overhaul or replacement of a machine.
19.4 REVISION POINTS
1. The location of a plant is a major decision affected by many factors both
internal and external to the organization operations”- Explain.

LESSON - 20
MOTION AND TIME STUDY
20.1. INTRODUCTION
“Motion study is the science of eliminating wastefulness resulting from
unnecessary, ill directed and inefficient motions. The aim of motion study is to find
and perpetuate the schemes of least waste methods of labour”. An analysis of the
motions used in an industrial process with an aim to improve efficiency and
productivity. A method to establish ‘the one best way to perform a task.”
It is mainly for the following three ways:
1. To get completely rid of as many human movements as possible
2. To shorten the movements be that he cannot get rid of
3. To make the necessary movements with less tiring
20.2 OBJECTIVES
To understand the procedure and advantages of motion study.
To know the concept and steps of time study.
To aware the performance rating and allowance factors.
20.3 CONTENTS
20.3.1 Motion study
20.3.2. Tools of motion study
20.3.3. Time study
20.3.4 Performance rating
20.3.5 Rating Scales
20.3.6 Allowance factor
20.3.7 Standard time
20.3.1 Motion Study
1. The procedure of performing a task is entirely from motion studies and more
effective operations are discovered.
2. Similarly there may be certain changes in the use of materials, machines and
equipments, ultimately leading to greater motivation and improved morales.
3. Date are always secured from which a series of job specification may be –
developed.
4. Motion study exerts a salutary influence upon the general morales of an
organization, particularly when the savings made are shared with the
employees.
PROCEDURE
1). Select and Define 2) record 3) critically examine 4) Develop the best 5)
Install and 6) Maintain.
226
Select and Define
It is to select the job worth studying and define the objectives to be achieved.
For this we must consider the following aspects.
i) Economic aspects ii) technical aspects iii) Human reactions
It is of no use in carrying out the study if the economic importance of the job is
small or if the job is likely to be discontinued or modified in near future.
Regarding technical aspects, one should make sure that adequate technical
knowledge is available to carry out the study.
Human reactions and employee attitudes are the most difficult to foretell since
mental and emotional reactions to investigations and changes have to be
anticipated.
It is readily accepted, if good industrial relations exist, and explained to all
concerned. Method study will be more readily accepted if started on jobs
unpleasant to workers, i.e. dirty jobs or those calling for the lifting of heavy weights.
If method study successfully removes the unpleasant features of these jobs,
reduces effort and fatigue of workers, they will naturally be less resistant to
cooperate. Method study with following objectives may be among the first to be
selected for motion study.
To reduce manufacturing cost.
To avoid bottlenecks which hold up other production operations
To reduce fatigue incurred by workers in order to increase their efficiency.
To avoid poor use of materials, labour or machine capacity that results in high
scrap and reprocessing costs.
To improve upon operations involving repetitive work using or great deal of
labour and liable to run for a long time etc.
Record
After selecting the job the next step is to record all the relevant information
and procedure pertaining to the present or existing method in detail and in the
form of a chart to obtain more clear picture about the same.
The success of an investigation depends upon the accuracy with which the
facts are portrayed because they will provide the basis of both the critical
examination and the development of the improved method. It is, therefore, essential
that the record be clear and concise. All the facts be related to the situation under
investigation obtained be, arranged for appraisal and comparison.
Critical Examination
The recorded events in sequence. The critical examination is achieved by
means of sets of detailed questions.
The primary questions to indicate the facts and the reasons underlying them.
The secondary questions to show the alternatives and consequently the means
of improvement.
227
Develop the Best Method
1. Record the method proposed through the critical examination.
2. Consult all levels of management and workers for their suggestions and
objections.
3. Test the modified proposed method for its advantages
4. Prepare and put up the report on proposed method to the management for its
final approval and subsequent implementation.
The proposed method appears to be sound requires further study and
development.
New method may require experimental work to develop it. Developing new
ideas, means looking of all aspects of manufacture in order to get the best possible
return from the ideas.
The development of new method is simplified to a certain extent by extracting
and working with the key activities that are suggested by the conclusions of the
critical examination.
In fact many ideas, developed after critical questioning require little capital
outlay. This is one of the major attractions of work study. It may be necessary to
modify a procedure, to get someone else to do a job and also for reorganise the way
of issuing work etc. But it needs cooperation of there.
Install: It has two stages:
1. Preparation and 2. Implementation
Preparation: It involves three stages viz., planning, arranging and rehearsing.
For the planning aspect, one person should be made responsible for the task,
actual dates should be fixed for each stage to complete and copies of any time -table
drawn up to cover the installation should be brought into time with the dates
selected for each stage.
Arranging aspect involves,
1. checking that all the necessary plant, tools and equipment are available and
that services are laid on
2. checking the availability and continuity of all materials, supplies and services
3. selecting workers for the proposed method and imparting them the necessary
training
4. Informing everyone concerned of the plans and time-table for the installation.
Rehearsing involves trail run of the proposed method using supervisors, work
study officers and the appropriate workers.
Implementation or actual installation involves the introduction of developed
method as standard practice.
During the initial period offer installation, a close watch should be kept so that
the problems associated with the proposed method are carefully studied and
remedied if necessary.
228
Installation phase is complete as the newly installed method starts working
smoothly and satisfactorily and gives encouraging results,
Maintain
Once the new method has seen installed it should be maintained in its
specified form and the workers should not be allowed to slip back into the old
method or introduce elements not allowed for unless there is very good reason for
doing so. To be maintained, a method must first be very clearly defined and
specified. Tools, layout and elements of movement must be specified beyond any
risk of misinterpretation.
Proper functioning of the installed method is ensured by periodic checks and
verifications. Purpose of checks and reviews is to find if the method being practiced
is the same or it has deviated from the authorised one.
Reason for deviation if any should be explored and the necessary changes may
be made in the procedure being practised so that it reverts to the authorized one.
Views of the workers, supervisors and other persons related with the installed
method can be of much help in exploring further improvements.
In a number of cases the conditions may change from time to time and this
may mean that some of the assumptions upon which the improved method was
built up are no longer valid. Therefore, the method should be reviewed at intervals
to make allowances, for any change may arise as a result of suggestion schemes.
20.3.2 Tools of Motion study
I. Process chart
A chart may be a diagram, a picture or a graph which gives an overall view of
the situation, say a process. It helps visualising various possibilities of alterations
or improvement. A chart representing a process may be called a process chart, A
process chart records graphically or diagrammatically in sequence, the operations
connected with a process. The chart portrays the process with the he lp of a set of
symbols and aids in better understanding and examining the process with a
purpose to improve the same.
II. Principles of Motion Study
The following principles must be borne in mind for effective motion study.
Rules of intelligent laziness: It means not to do a job in hard way if there is an
easier way like:
1. Don't do jobs by hand if machines can, do them
2. Eliminate handling
3. Use the fewest motion possible
4. Use fixed positions for small materials and tools.
Rules for keeping busy
Use two hands and, also use the feet as well as the hands if they can be used.
229
Rules for Reduction
Transfer all heavy lifting to mechanical lifting devices
Use momentum where possible rather than force.
Continuous curved motions are easier and less firing that motion involving
sharp changes in direction.
Assign all work to the body member best suited for it.
Use the body to the best advantages mechanically
Eliminate working conditions that add to fatigue
On fatiguing jobs allow rest periods.
On Mononotonous jobs provide an occasional break.
Rules for placing men: Use man-power to its best advantage considering the
job to be filled and the man available. Where there are several workers doing the
same job day after day split the job into small tasks and let them specialize.
III. Motion Study Questions
Ask some questions related to the job. Some general questions are i) who,
where, why, when and how is the job is done? Is this movement necessary? can it
be eliminated? can it be shortened? can it be transferred to the machine? etc.
IV. Micromotion Study
Micromotion study way of improving jobs means taking moving picture of jobs,
then running them slowly through a prerector, by studying the pictures a trained
analyst can figure out how to improve even short-cycle jobs. After improving the
job, a moving picture of the new method is a perfect and permanent record of how
the work is done. Besides furnishing a record, movies help in the training of men
particularly new time and motion study men. They can run and return the films
and they can practice setting time standards without getting out into the factory
until they have little experience. But it is costly and also not welcomed by unions.
V. Therbling Analysis
A therbling is a small part of a job. It is much too short to time with a stop
watch. A time study man analyses jobs part by part but his parts of job would stop
at say "tightenbolt". Tighten bolt is made up of the therblings move band, get ready
to pick up wrench, grasp wrench; move hand with wrench, position wrench and so
on. No one paid much attention, to until it has a rebirth during World war II when
the government set up training programmes to show frames how to improve jobs.
Today several consulting engineering companies use it as a bread-and-butter,
technique.
20.3.3 Time Study
Time study is defined as "A searching scientific analysis of methods and
equipment used or planned in doing a place of work, development practical detail of
the best way of doing it and determination of the time required. An important part
of the concept in this definition is that time study and the job standardization of
230
which it is a part are more than timing, with a watch. Taylor says. "Here statistics
as to time which a man takes to do a given piece of work do not constitute a time
study. Time study involves careful study of the time in which work ought to be
done.
BASIC STEPS IN TIME STUDY
The following eight steps constitute the time study process exclude the
selections' of the job for the worker which have to be done before the steps in the
list are taken up;
a) Obtaining and recording all the available information about the job, operator
and the surrounding conditions likely to, affect the execution of work.
b) Recording the complete description of the method, breaks down the operation
into 'elements'.
c) Examining the detailed breakdown to ensure the most effect method and
motions are being used and determining sample size.
d) Measuring with a timing device (stop-watch), and record the time taken by the
operator to perform each element the operation.
e) At the same time, assessing the effective speed of working the operator relative
to the observers concept of the rate corresponding to standard rating.
f) Extending observed time to "basic times".
g) Determining the allowances to be made over and above the basic time for the
operation.
h) Determining the "standard time" for the operation.
The stop watch
Usually, three types of stop watches are used for performing time study;
i) Flyback type, ii) Non-flyback type, and iii) the split hand stop-watch type.
However the first two types are used for a large majority of cases.
Timing elements by stop-watch
There are two principal methods of timing with the stop-watch, a) Cumulative
timing and b) Flyback timing. In cumulative method the watch runs continuously
throughout the study. It is started at the beginning of the first element of the first
cycle to be timed and is stopped after the study is completed. The purpose of this
procedure is too sure that all the time during which the job is observed is recorded
in the study.
In flyback method the stop-watch is reset to zero reading, by returning the
hands of the watch to zero, at the end of each element and the hands of the watch
are allowed to start immediately at the beginning of the next element, the time for
each element being observed directly.
In case of flyback timing, the study man reaches the clock at an exact minute
preferably at the next major division such as the hour or one of the five minute
points, and sets his stop-watch running, noting the exact time in the "time on"
space. He reaches the location where the study is to be made water running and
231
allows it to do so till he is ready to start timing. At the beginning of the first element
of the first work cycle, as the hands are snapped back there is nothing in the fi rst
entry to show for the time that has elapsed. At the end of the study, the hand is
snapped back to zero on completion of the last element of the last cycle and
thereafter allowed to run continuously until he can again reach the clock and note
the time of finishing when the watch is finally stopped. The final clock time is
entered in the "time off' space on the form. The two times recorded before and after
the study are known as "check times". The clock reading at the beginning of the
study is subtracted from the clock reading at the end of the study yielding the
elapsed time, to be entered in its appropriate location.
The recorded time is obtained as the aggregate of time of all the elements, i.e.,
other activities noted in the study and ineffective time and check time are also
noted. This aggregate should ideally equal the elapsed time but in practice is found
to be different from the elapsed time. The difference may be attributed to the
cumulative loss of very small fractions of time at the return of the hand to zero and
to bad reading of missed elements. The difference observed in case of cumulative
timing is less since there is no loss due to snapback effects.
Cumulative timing has the significant advantage that even in the event of
missing element or non-recording of some occasional element it does not have any
effect on the overall time. However, cumulative timing calls for spending of more
time in determining individual element timing which can be only obtained after
performing a subtraction operation.
Distinction between Time and Motion Study
Motion study is concerned with a study of work done by the workman with
sufficient consideration of the arrangement of machines and their functioning to
insure efficient worker production, whereas time study includes a detailed analysis
of both machine time or the time taken by the machine doing its share of the work
and ‘Manual’ time or the time taken by the workman, Manual time will usually be
found to be of three general classes (i) the handling of tools used by the workman,
in connection with the job (ii) the handling of the machine by the workman and (iii)
the handling of the material that being worked upon.
20.3.4 Performance rating
Rating and allowances are the two most controversial aspects of time study.
Most time study in industry are used to determine standard times for setting
workloads and as a basis for incentive plans procedures employed have a bearing
on the earnings of the workers as well as on the productivity. Time study is not an
exact science, although much research has been and continues to be undertaken to
attempt to establish a scientific basic for it. Rating (the assessment of a worker's
rate of working) and allowances to be given for recovery from fatigue and other
purpose still largely matters of judgement and therefore of bargaining between
management and labour.
232
It has, already, been said that time studies should be made as far as possible,
on a number of qualified workers; and that very fast very slow workers should be
avoided, at least while making the first few studies of an operation. Who is a
"qualified worker"? A Qualified Worker is one who is accepted as having the
necessary physical attributes, who possesses the required intelligence and
education, and who has acquired the necessary skill and knowledge to carry out
the work in hand to satisfactory standards of safety, quantity and quality.
The acquisition of skill is a complicated process. It has been observed that
among the attributes which differentiate the experienced worker from the
inexperienced are the following:
a) achieves smooth and consistent movements;
b) acquires rhythm;
c) responds more rapidly to signals;
d) anticipates difficulties and is more ready to overcome them
e) carries out the task without giving the appearance conscious attention and is
therefore more relaxed.
Rating is the assessment of the worker's rate of working relative to the
observer's concept of the rate corresponding to standard pace and standard
performance is the rate of output which qualifier workers will naturally achieve
without over-exertion as an average over the working day or shift, provided that
they know and adhere to the specified method and provided that they are motivated
to themselves to their work. This performance is denoted as 100 on the standard
rating and performance scales.
Rating of effort
The purpose of rating is to determine, from the time actually taken by the
operative being observed, the standard time which can be maintained by the
average qualified worker and which can be used as realistic basis for planning,
control and incentive schemes. What the study man is concerned within therefore
the speed with which the operative carries out the work, in relation to the study
man's concept of a normal speed.
Speed of what? Certainly not merely speed of movement, because an unskilled
operative may move extremely fast and yet take longer to perform an operation than
a skilled operative who appears to be working quite slowly. The unskilled operative
puts in a lot of unnecessary movements which the experienced operative has long
since eliminated. The only thing that counts is the effective speed of the operation.
Judgement of effective speed can only be acquired through experience and
knowledge of the operations being observed. It is very easy for an inexpe rienced
study man either to be fooled by a large number of rapid movements into believing
that an operative is working apparently slow movements are very economical of
motion. The amount of effort which has to be exerted and the difficulty encountered
by the operative is a matter for the study man to judge in the light of his experience
with the type of job. Operations involving mental activities (Judgement of finish, for
233
example, in inspection of work) are most difficult to assess. Experience of the type
of work is required before satisfactory assessments can be made. Inexperienced
study men can be made to look very foolish in such cases, and moreover can be
unjust to above-average and conscientious workers.
In any job the speed of accomplishment must be related to an idea of a normal
speed for the same type of work. This is an important reason for doing a proper
method study on a job before attempting to set a time standard. It enables the
study man to gain a clear understanding of the nature of the work and often
enables him to eliminate excessive effort or judgement and so bring his rating
process nearer to a simple assessment of speed.
20.3.5 Rating Scales
There are several scales of rating in use, the most common of which are those
designated the 100-133 scale, the 60-80, the 75- 100, and the British Standard
scale which is the 0-100 scale. The newer" 0-100 scale has, however, certain
important advantages which have led to its adoption as the British Standard. In the
0- 100 scale, 0 represents zero activity and 100 the normal rate of working of the
motivated qualified worker- that is, the standard rate.
Determination of basic time
The number 100 represents standard performance. If the study man decides
that the operation he is observing is being performed with less effective speed than
his concept of standard, he will use a factor of less than 100, say 90 or 75 or
whatever he considers represents a proper assessment. If, on the other hand, he
decides that the effective rate of working is above standard, he gives it a factor
greater than 100- say, 110, 115 or 110.
It is usual practice to round off ratings to the nearest multiple of five on the
scale; that is to say, if the rate is judged to be 13% above standard, it would be put
down at 115. During the first weeks of their training, study men are unlikely to be
able to rate more closely than the nearest ten.
If the study man's ratings were always impeccable, then, however, many times
he rates and times are element the result should be that-
Observed Time * Rating = A Constant
An example, expressed numerically, might read as follows:
Cycle Observed time Rating Constant
(decimal minutes)
1. 0.20 * 100 = 20
2. 0.16 * 125 = 20
3. 0.25 * 80 = 20
and so on
234
It is always a comparison with the standard rating. So, if the standard rating is
taken to be 100, then dividing the constant by the standard rating (100) will yield
the constant known as the "basic time" for the element.
Observed Time *= Rating
=Basic Time Standard Rating
For example
0.16 * -yg = 0.20 min.
Recording the rating
In general, each element of activity must be rated during its performance
before the time is recorded, without regard to previous of succeeding elements.
It is important that the rating should be made while the element is in progress and that
it should be noted before the time is taken, as otherwise there is a very great risk that
previous times and ratings for the same element will influence the assessment. Since the
rating of an element represents the assessment of the average rate of performance for that
element, the longer the element the more difficult it is for the study man to adjust his
judgment to that average. Long elements, though timed as a whole up to the break points,
should be rated every half minute.
Ratings to the nearest five is found to give sufficient accuracy in the final
result. Greater accuracy than this can be attained only after very long training and
practice.
20.3.6. Allowance Factors
The determination of allowances is the most controversial part of work study.
The fact that the calculation of allowances cannot be altogether accurate under all
circumstances is no excuse for using them as a dumping ground for any factors
that have been missed or neglected in making the time study. The difficulty
experienced in preparing a universally accepted set of precise allowances that can
be applied to every working situation is due to various reasons. The most important
among them are-
1) Factors related to the Individual
If every worker in a particular working area was to be considered individually
it might well be found that a thin, active, alert worker at the peak of physical
condition required a smaller allowance to recover from fatigue than the other
worker. Similarly, every worker has a unique learning curve which can affect the
manner in which he conducts his work. There is also some reason to believe that
there may be ethnic variations in the response to the degree of fatigue experienced
by workers, particularly when engaged on heavy manual work.
2) Factors related to the nature of work itself
Many of the tables developed for the calculation of allowances give figures
which may be acceptable for light and medium work in industry but which are
inadequate when applied to operations involving very heavy and strenuous work
235
such as work beside furnaces in steel mills. Moreover every working situation has
its own particular attributes which may affect the degree of fatigue experienced by
the worker or may lead to unavoidable delay in the execution of a job. Other factors
inherent in the job can also contribute to the need for allowances, although in a
different way- for example, when protective clothing or gloves have to be worn, or
when there is constant danger or when there is a risk of spoiling or damaging the
product.
3) Factors related to the environment
Allowances in particular relaxation allowances, have to be determined with
due regard to various environmental factors such as heat, humidity, noise, dirt,
vibration, light intensity, dust, wet conditions and so on. Each of these will affect
the amount of relaxation allowances needed. Environmental factors may also be
seasonal in nature. This is particularly so for those who work in the open air, such
as workers in the construction industry or in shipyards.
Relaxation allowances
Relaxation allowance is an addition to the basic time intended to, provide the
worker with the opportunity to recover from the physiological and psychological
effects of carrying out specified work under specifi ed conditions and to allow
attention to personal needs. The amount of allowance will depend on the nature of
the job.
Relaxation allowances are calculated so as to allow the worker to recoveror
from fatigue. Fatigue may be defined as physical and/or mental weariness, real or
imagined, existing in a person and adversely affecting his ability to perform work.
The effects of fatigue can be lessened by rest pauses, during which the body
recovers from its exertion, or by slowing down the rate of working and thus
reducing the expenditure of energy.
Allowances for fatigue are normally added element by element to the basic
times, so that a work value for each element is built up separately, the element
standard times being combined to yield the standard time for the whole job or
operation. In this way it is possible to deal with any extra allowance which may be
required to compensate for severe climatic conditions, since the element may
sometimes be performed in cool weather and sometimes when it is very hot.
Allowances for climatic conditions have to be applied to the working shift or
working day rather than to the element or job, in such a way that the amount of
work which the worker is expected to produce over the day or the shift is reduced.
The standard time for the job remains the same, whether the job is performed in
summer or winter, since it is intended to be a measure of the work that the job
contains.
Relaxation allowances have two major components; fixed allowances and
variable allowances.
Fixed allowances are composed of
236
1. Allowances for personal needs: This allowance provides for the necessity to
leave the workplace to attend to personal needs such as washing, going to the
lavatory and getting a drink. Common figures applied by many enterprises
range from 5 to 7%.
2. Allowances for basic fatigue: This allowance always a constant is given to
take account of the energy expended while carrying out work and to alleviate
monotony. A common figure is 4% of basic time. This is considered to be
adequate for a worker who carried out the Job while seated who is engaged on
light work in good working conditions and who is called upon to make only
normal use of hands, legs and senses.
Variable allowances are added to fixed allowances when working conditions
differ markedly from those stated above, for instance because of poor environmental
conditions that cannot be improved, added stress, and strain in performing the job
in question and so on.
Rest pauses: Relaxation allowances can be taken in the form of rest pauses.
While there is no hard and fast rule governing rest pauses, a common practice is to
allow a 10 to 15 minutes break at mid-morning and mid-afternoon often coupled
with facilities for tea, coffee or cool drinks or snacks and to permit the remainder of
the relaxation allowance to be taken at the discretion of the worker.
Rest pauses are important for the following reasons:
1. They decrease the variation in the worker's performance throughout the
day and tend to maintain the level nearer the optimum.
2. They break up the monotony of the day.
3. They give the workers the chance to recover from fatigue and to attend to
personal needs.
4. They reduce the amount of time off taken by workers during working
hours.
Contingency Allowances
A contingency allowance is a small allowance of time which may be included in
a standard time to meet legitimate and expected items of work or delays, the precise
measurement of which is uneconomical because of their infrequent or irregular
occurrence.
The allowance provides for small unavoidable delays as well as for occasional
and minor extra work and so It would be proper to split the allowance into these
components, the contingency allowance for work being allowed to attract fatigue
allowance just as any other items of work does, and the delay part of the allowance
being given with only a personal needs increment. In practice this is a distinction
which is often ignored. Contingency allowances are always small and it is usual to
express them as a percentage of the total repetitive basic minutes in the job, adding
them to the rest of the work in the job and adding a relaxation percentage to the
whole contingency allowance. Contingency allowance should not be more than 5%
237
and should only be given in cases where the study man is absolutely satisfi ed that
the contingencies cannot be eliminated and that they are justified.
Policy allowances
A policy allowance is an increment, other than bonus increment, applied to
standard time (or to some constituent part of it, eg. work content) to provide a
satisfactory level of earnings for a specified level of performance under exceptional
circumstances.
Policy allowances are not a genuine part of time study and should be used
with the utmost caution and only in clearly defined circumstances. They should
always be dealt with quite separately from basic times, and if used at all, should
preferably be arranged as an addition to standard times, so as not to interfere with
the time standards set by time study.
The usual reason for making a policy allowance is to line up standard times
with the requirements of wage agreements between employers and trade unions. In
several enterprises in the United Kingdom, for example, the incentive performance
is generally set at such a level that the average qualified worker as defined, can
earn a bonus of 33.5% of his basic time rate if he achieves standard performance.
There is no need to apply a policy allowance to achieve this state of affairs; it is
simply necessary to arrange for the rate paid per standard minute of work produced
to be 133.5% of the basic time rate per minute, and in general it is better to
accommodate any special wage requirements in this way, by adjusting the rate paid
per unit of work rather than the standard time.
Special Allowances
Special allowances may be given for any activities which are not normally part
of the operation cycle but which are essential to the satisfactory performance of the
work. Such allowances may be permanent or temporary. Wherever possible, these
allowances should be determined by time study.
When time standards are used as the basis for a payment -by- results scheme,
it may be necessary to make a start-up allowance to compensate for time taken by
any work and any enforced waiting time which necessarily occurs at the start of a
shift or work period before production can begin. A shut down allowance may
similarly be given for work or waiting time occurring at the end of the day. A
cleaning allowance is of much the same character it is given when the worker has
to give attention from time to time to cleaning his machine or workplace. Tool
allowance is an allowance of time to cover the adjustment and maintenance of
tools.
A small batch allowance is required to enable a worker working on small
batches to decide what to do and how to go about it and then to work up to a
standard performance by practice and repetition. The calculation of this allowance
will depend on whether it is a one-of-a-type batch or not, on the length and batch
size or run length and on the frequency of similar work and its degree of
complexity.

20.3.7. STANDARD TIME
It is now possible to obtain a complete picture of the standard time for a
straightforward manual job or operation, one which is considered to attract only the
two allowances which have so far been discussed in detail: contingency allowance
and relaxation allowance. The standard time for the job will be the sum of the
standard times for all the element of which it is made up, due regard being paid to
the frequencies with which the elements recur, plus the contingency allowance
(with its relaxation allowance increment). In other words- Standard time is the total
time in which a job should be completed at standard performance.
