2. INTRODUCTION TO ECONOMICSINTRODUCTION TO ECONOMICS

3. Several economists have defined economics taking
different aspects into account. The word ‘Economics’
was derived from two Greek words, oikos(a house)
and nemein(to manage) which would mean ‘managing
an household’ using the limited funds available, in the
most satisfactory manner possible.
• “Economics is a study of the ways in which people
use resources to satisfy their wants”.

4. Adam smith (1723 - 1790),
Father of Economics
Book “An Inquiry into Nature and Causes
of Wealth of Nations” (1776) .
Defined economics as the practical science of production and
distribution of wealth.

5. Alfred Marshall (1842 - 1924) wrote a book “Principles of
Economics” (1890)
 Welfare definition
 defined “Political Economy” or Economics is a study of
mankind in the ordinary business of life;
 it examines that part of individual and social action which is
most closely connected with the attainment and with the use of
the material requisites of well being”.

6.  Lionel Robbins (Scarcity definition)
 book “An Essay on the Nature and Significance of Economic
Science” in 1932.
 According to him, “economics is a science which studies
human behaviour as a relationship between ends and scarce
means which have alternative uses”
 Ends – human wants
 Means – resources with which wants are fulfilled

7. Based on all these definition,Economics can be defined
as:
“Economics is the social science that examine how
people choose to use limited or scare resources I
attempting to satisfy their unlimited wants.”

8. Microeconomics
Macroeconomics
International economics
Development economics
Environmental economics
Urban and rural economics

9. This is considered to be the basic economics.
Microeconomics may be defined as that branch of economic
analysis which studies the economic behavior of the individual
unit, may be a person, a particular household, or a particular
firm.
It is a study of one particular unit rather than all the units
combined together.
microeconomics is also described as price and value theory, the
theory of the household, the firm and the industry. Most
production and welfare theories are of the microeconomics
variety.

10. Macroeconomics may be defined as that branch of
economic analysis which studies behavior of not one
particular unit, but of all the units combined together.
 Macroeconomics is a study in cumulative. Hence it is
often called Aggregative Economics.

11. As the countries of the modern world are realizing the
significance of trade with other countries, the role of
international economics is getting more and more
significant now a days.

12. As after the second world war many countries got
freedom, their economics required different treatment
for growth and development.
 This branch developed as development economics.

13. Unchecked emphasis on economic growth without
caring for natural resources and ecological balance,
now, economic growth is facing a new challenge from
the environmental side.
Therefore, Environmental Economics has emerged as
one of the major branches of economics that is
considered significant for sustainable development.

14. Role of location is quite important for economic ability.
There is also much debate on urban-rural divide.
Therefore, economists have realized that there should be
specific focus on urban areas and rural areas.
Therefore, there is expansion of branches like urban
economics and rural economics.

15. Economics - A Science and an Art
Economics - A Social Science
Economics is both positive and normative science.

16. It is science in the sense, it is a systematic knowledge
derived from scientific study, observation &
experiments based on scientific methods.

17.  Economics is an art too because an art is a system of
rules for the attainment of given end. There are several
branches of economics which provide practical guidance
in the solution of economic problem.
 Its is a science in its methodology and an art in its
application.

18. Positive science: It only describe what it is and normative
science prescribe what it ought to be. Positive science
does not indicate what is good or what is bad to society
Normative Science: It makes distinction between good
and bad .It prescribe what should be done to promote
human welfare.

19. How much will a new petrol
tax raise the price of petrol?
Will an increase in the
minimum wage increase
unemployment?
Why is the price of Pop corn
is Rs 4.20 ?
 Should there be a new tax
on petrol?
 Should there be an
increase in the minimum
wage?
 What should the price of
Pop corn be?
Therefore, economics is a positive as well as normative
science.
