INTRODUCTION
DFINITIONS OF ECONOMICS AND
MANAGERIAL ECONOMICSECONOMICS: Economics is a social science . Its basic
function is to study how people – individual house holds, firms and nations maximizing their gains from their limited resources and opportunities.
In economic terminology it is called as “maximizing behaviour” or more approximately “optimizing behaviour” .
Optimization means selecting best out of available resources with the objective of maximizing gains from given resources.
Economics is thus a social science, which studies
human behaviour in relation to optimizing
allocation of available resources to achieve the
given goals.
Eg : individual household behaviour, firm, industry
and nation
Economics is also a study of choice-making
behaviour of the people.
The origin of the subject could be traced from the works of the
Greek philosopher Aristotle who confined the study of
economics to household management and acquiring, guarding
and making proper use of wealth.
The term economics is derived from two Greek words
“OIKOS”(a house) and “NEMEIN”(to manage).
Prof. Samuleson remarks economics as “the oldest of arts and
newest of science, indeed the queen of the social science.

Managerial economics can be broadly defined as
the study of economic theories, logic and tools
of economic analysis that are used in the
process of decision making. Economic theories
and techniques of economic analysis are applied
to analyze business problems, evaluate business
options and opportunities with a view to arriving
at an appropriate business decision.
Managerial Economics
Douglas : Managerial economics is concerned
with the application of economic principles and
methodologies to the decision making process
within the firm or organization. It seeks to
establish rules and principles to facilitate the
attainment of the desired economic goals of the
management.
Mansfield : He defines that managerial economics
is concerned with the application of economic
concepts and economic tools to the problems of
formulating rational decision making.
Spencer and Seigleman : It is the integration of
economic theory with business practice for the
purpose of facilitating decision making and
forward planning by management
Economic Theory and Managerial Theory

5. It studies economic aspects of
the problem
1. It deals with the application of
certain principles to solve the
problem of a firm
2. It has only micro characteristics
3. It deals with the study of only profit
theories
4. In managerial theory assumptions
disappear due to practical situations
5. It studies both economic and non-

Scope of Managerial Economics
Economics has two major branches
1. Micro Economics
2. Macro Economics
The term Micro means small and Macro means big.
Both are applied to business directly or indirectly.
managerial economics comprises both micro and
macro economic theories. The parts of micro and
macro economics that constitute managerial
economics depend on the purpose of analysis.
The scope of M.E. comprises all the economic concepts, theories and tools of analysis which can be used for analyse the issues related to demand , production and cost, market structure etc.,
In other words managerial economics is economics applied to analysis of business problems and decision making . Broadly it is applied economics
Micro-economics applied to internal issues :
Operational issues are of internal nature. Internal issues include
all those problems which arise within the business organization
and fall within purview and control of the management .
Some of the basic internal issues are :
What to produce
How much to produce
Choice of technology i.e. choosing of the factor –combination
Choice of price i.e. how to price the commodity
How to promote sales
How to face the price competition
How to decide on new investments
How to manage capital and profit
How to manage inventory i.e. stock of both
finished goods and raw material
Most of the micro economic problems deals with
most of these questions.
The Law Demand
The Theory of Production
Analysis of Market Structure and Pricing
Theory
Profit analysis and management
It guide firms in the measurement and management
of profit , in making new allowances for the risk
premium, in calculating the pure return on capital
and pure profit and also for future planning.
Theory of Capital and Investment Decisions
Knowledge of capital theory can contribute a
great deal in investment-decision making, choice of
projects, maintaining the capital, capital budjeting
etc.
Macro-economics deals with external issues :
The type of economic system in the country
General trends in N.I., employment, prices, savings and
investments
Structural change in the working financial institutions
viz., banks, insurance companies etc
Magnitude of and trends in foreign trade
Trends in labour supply and strength of capital market
Government’s economic policies i.e., industrial,
monetary, fiscal, price and foreign etc.
Social factors viz., value system of the society,
property rights, customs and habits etc.,
Political environment i.e., democratic, authoritarian,
socialist political systems, or state attitude towards
private business man etc.
These Environmental factors have a far-reaching
bearing upon the functioning and performance of the
firms. Therefore, decision makers have to take in to
account the present and future economic, political and
social
Conditions in the country and give due consideration
to the environmental factors in the process of decision
making.
Eg : SEZ in the Nandigram, Tata’s small car in Singur
district in West Bengal

PRODUCTION PLANNING AND COST REVENUE DECISIONS
Production Function :
The production function is a technological
relationship between output and various inputs used
in production viz., land, labour, capital and
technology.
The output depends on the increasing function of
all the factor inputs
Q=f(S,L,K,T)
The following types of cost are useful in the
decision areas

Fixed and Variable Cost
Direct and Indirect Cost
Replacement and Original Cost
Opportunity and Industrial Cost
Sunk Cost and Outlay Cost
STUDY OF ECONOMIC ENVIORNMENT

structures. The structure of the market refers to the degree
of competition in the market for the firms goods and
services. MarketPerfect competition
Monopoly market
Monopolistic market
Oligopoly market
INVESTMENT DECISION
Business firms invest large money in their
projects. Therefore, capital expenditure for
different project proposals compete within
themselves for their claim on scarce resources.
Generally , in business sector itself, individual
firms compete against access to financial
resources and scares .
The investment decisions are important as
Not easily reversible
Generally involves large sums of money
Highly futuristic and future is full of uncertainty
Long gestation periods
Thus, careful financial appraisal of each project
involves larger investments. Due to above reasons,
capital decisions fall in the category of investment and
known as “capital budgeting decisions” made by
highest level of management.
STEPS IN DECISION MAKING
Managerial economics is concerned with decision
making at the level of firm. These decisions have far
reaching effects on the firm. Delay in taking
decisions or implementing decisions might turn in to
losses.
Various steps in the decision making by a business firm
are as fallows :
Defining business problem
Determining objective
Exploring available alternatives
Assessing consequences of various alternatives
Choosing best alternative
Performing sensitive analysis
