INTRODUCTION TO ECONOMICS
The word economics is derived from the Greek word “Oikonomos” which means to manage the house. So it means the management of a household specially in those matters which are relating to the income and expense of the family. After sometimes the term political economy was also used for this topic and slowly political economy adopted the shape of economics.

DEFINITION OF ECONOMICS
“Economics is the study of our behavior in producing, distributing and consuming material goods and services in a world of scarce resources”
04/08/23 18
DEFINITION OF ECONOMICS
There are numerous definitions of economics but there are three important definitions given as below.
ACCORDING TO ADAM SMITH ACCORDING TO ALFERED MARSHALL ACCORDING TO PROF.ROBBINS
04/08/23 19
ACCORDING TO ADAM SMITH
“Science of Wealth”
He was the founder of classical school of thought. Adam smith wrote the book”An enquiry into the nature and causes of wealth of nations in 1776.” He was called “Father of Economics”
Economics is a science of wealth: He divided his book into four parts like1. Consumption of wealth 2. Production of wealth3. Exchange of wealth4. Distributing of wealth
04/08/23 20
DR.MARSHALL“Science of Material
Welfare” Dr.Marshall is the founder of neo classical school
of thought. He wrote a book “Principles of Economics”in 1878 and defined economics in the following words.
”Economics is a study of Man,s action in the ordinary business of life it enquires how he gets his income and how he uses it. It examines that part of an individual and social actions which is mostly closely connected with the attainment and with the use of material requisites of well being. Thus economics is on one side a study of wealth and on the other and more important side apart of the study of man.”
04/08/23 21
PROF. ROBBINS“Science of Scarcity” Prof.Robbins criticized the Marshalls
definition and offered the most precise and scientific definition of economics.
”The science which studies human behavior as a relationship between ends and scarce means, which have alternative uses.”
04/08/23 22
Engineering Economics
“Engineering Economy is the discipline concerned with the economic evaluation of the costs and benefits of proposed technical projects. The principles and methodology of engineering economy are an integral part of the daily management and operation of private-sector companies and corporations, regulated public utilities, govt. unit or agencies, and non profit organizations.”
04/08/23 23
Engineering Economy
“These principles are utilized to analyzed alternative uses of financial resources, particularly in relation to the physical assets and the operation of an organization.”
So Engineering Economy will prove to be invaluable to you in assessing the economic merits of alternative uses of your personal funds.
04/08/23 24
Engineering Economy
“In other words we may say that the Engineering Economy is the application of economic techniques to the evaluation of design and engineering alternatives.
The Role Of Engg. Eco. The role of engineering economy is to assess the appropriateness of a given project, estimate its value, and justify it from an engineering standpoint.

IMPORTANCE OF ECONOMICS IN LIFE:Now a day no body can deny the importance of economics in our real life. Our social cultural and religion values are deeply affected by the economics circumstances of the people. All the people living anywhere in the world are doing economic efforts for solving their economic problems.IN THE WORDS OF DURBIN:
“ Economics is the intellectual religion of the day”

Branches of Economics
Micro economics
Macro economics
04/08/23 31
Micro economic
“The study of decision making undertaking by individual”
Individual may be any one Consumer. (Rational person) Producer. (Wise) Firms. (Making decision about
products)
04/08/23 32
MACROECONOMICS“It is the study of the behavior of
economy as a whole” National income. Economic development and planning. Unemployment. International trade. Balance of payment. Public sector. Inflation

Scarcity
These three questions create theory of Choice but the resources are scarce and so concept of scarcity arises.
“The amount of something which is less than the amount required to meet the demand of the people at market price.”
So Scarcity forces us to make choices.
04/08/23 39
Opportunity Cost
It creates another concept called Opportunity Cost.
“Things which we sacrifice to get something”
Example Opportunity cost of Bicse is ____________.

Possibility Lines
Opportunity Cost concept helps us to develop possibility lines as follows
Consumption Possibility Line Production Possibility Line
04/08/23 41
Consumption Possibility Line
Commodity X
Commodity Y
Y0 X1
Y1
X2
For an increase in quantity of Y, amount of x will be sacrificed for consumption.
Consumption

For an increase in quantity of Y, amount of x will be sacrificed for Production.
