1.4 Micro vs. Macroeconomics
•Economics is a study about how individuals, businesses and governments
make choices on allocating resources to satisfy their needs.
• These groups determine how the resources are organised and coordinated
to achieve maximum output. They are mostly concerned with the
production, distribution and consumption of goods and services.
•The modern economic theory is divided into two branches-
microeconomics and macroeconomics.
•Microeconomics is the analysis of the individual behaviour. It focuses on
individual consumers and businesses.
•Macroeconomics ,on the other hand, is the analysis of mass or aggregate
behaviour.
•Microeconomics and macroeconomics are the core of economics. Ragnar
Frisch of Oslo University has developed these two terms.

1.4.1 Microeconomics:
•The term ‘micro’ is derived from the Greek worf ‘mikros’ which means
small. Thus, micro-economics is the theory of small.
•Microeconomics is that branch of Economics which studies an economic
or decision making unit and considers in detail the behaviour of that
particular unit.
•Microeconomics is the study of decisions made by people and businesses
regarding the allocation of resources and prices of goods and services.
•Microeconomics focuses on the supply, that determines the price level of
the economy.
• It uses the bottom-up approach strategy to analyze the economy.
• In other words, Microeconomics tries to understand human choices and
resource allocation.
•Microeconomics does not decide what are the changes taking place in the
market, instead, it explains why there are changes happening in the market.
•One of the major goals of microeconomics is to analyze the market and
determine the price for goods and services that best allocates limited
resources among the different alternative uses.
By: Shuchi Goel 10

•This study is especially important for producers as they decide what to
manufacture and the appropriate selling price.
•Microeconomics assumes businesses are rational and produce goods
that maximizes their profit.
•If each firm takes the most profitable path, the principles of
microeconomics state that the market’s limited resources will be
allocated efficiently.
•The main key role of Microeconomics is to examine how a company could
maximize its production and capacity, so that it could lower prices and
better compete in its industry.
•A lot of microeconomic information can be obtained from the financial
statements.
•The key factors of Microeconomics are :
Demand, Supply, and Equilibrium
Production Theory
Costs of Production
Labor Economics
•Examples:
 
Individual Demand, Price of a product.
By: Shuchi Goel 11

•Microeconomics has application in various diversified fields of Economics
such as agricultural economics, labour economics, etc.

1.4.2 Macro Economics:
•The term macro is derived from the Greek word ‘makros’ which means
‘large’.
•Most of the modern economics is now macroeconomics, It has become
popular only after the publication of John Maynard Keynes’s ‘General
Theory of Employment, Interest and Money’ in 1936.
•Besides Keynes, Robert Malthus, Karl Marx, Leon Walras and Irving
Fisher were among the prominent economists who contributed to the
development of the macroeconomic analysis.
•Macroeconomics is concerned with the analysis of the economy as a
whole. It studies the entire economic system or its major components
such as households, business firms and government. It deals with total
private consumption expenditure, total private investment expenditure,
total government expenditure, total imports and exports of goods as well as
services, etc. It seeks the causes and cures for unemployment, inflation,
balance of payments deficits, etc.
•Macroeconomics is the study of the performance, structure, behavior and
decision-making of an economy as a whole.
By: Shuchi Goel 13

•Thus, macroeconomics is not concerned with a particular decision
making unit, but, with all such units combined together. It presents a
complete picture of the economic system. That is why, the macro-
economics is termed as aggregative economics.
•In the words of Kenneth E.Boulding, “Macroeconomics deals not with
individual quantities but with aggregate of these quantities, not with
individual incomes but with national income, not with individual prices but
with price levels, not with individual outputs with the national output.”
•Macroeconomists focus on the national, regional, and global scales. For
most macroeconomists, the purpose of this discipline is to maximize
national income and provide national economic growth. Economists hope
that this growth translates to increased utility and an improved standard of
living for the economy’s participants.
•To achieve the goals, macroeconomists develop models that explain the
relationship between factors such as national income, output, consumption,
unemployment, inflation, savings, investment and international trade.
•These models rely on aggregated economic indicators such as GDP,
unemployment, and price indices.
By: Shuchi Goel 14

•On the national level, macroeconomists hope that their models help
address two key areas of research:
1.the causes and consequences of short-run fluctuations in national income,
otherwise known as the business cycle, and
2.what determines long-run economic growth.
•The analysis of macroeconomics has acquired great significance in recent
years. The movements in economic aggregates influence the health of the
macro economy and economic fortunes of individuals. Macroeconomics
explains as to why some economies grow with increases in their living
standards, while others do not. The study of macroeconomics is useful
in many ways:
i.Formulation and Execution of Economic Policies: The government
intervention in the economic activities has been increasing day by day. The
government, however, can not deal with a particular individual or with
small groups. (Cont..)
By: Shuchi Goel 15

Hence, the study of the macroeconomics becomes very important at
the time of formulation and execution of economic policies.
ii.Functioning of Economy: It is very difficult to interpret the functioning
of an economy in terms of microeconomics, as there are numerous
decision making units in the economy. One can understand the complex
economic system through the study of national aggregates like income,
output, expenditure, saving and investment.
iii.Helps to Understand Microeconomics Better: The study of the
macroeconomics makes the understanding of microeconomics better.
For instance, the law of diminishing marginal utility has been framed by
observing the behaviour of many consumers in the society.
iv.Study of Economic Development: The macroeconomic developments
have led to the study of the economic growth. This has enabled us to study
and understand the problems of the underdeveloped countries. By
analysing such problems, it has become possible for us to promote the
development of these countries.
By: Shuchi Goel 16

v.Study of Welfare: It is not possible to measure the size of welfare in
terms of the microeconomics. Movements in macro economic
aggregates reflect the health of the sectors in which the individuals
work and the prices of the goods that they purchase.
vi.International Comparisons: Macroeconomics facilitates international
comparisons by providing information about aggregate demand,
national income, consumption and saving for different countries.
1.4.3 Difference Between Micro and Macroeconomics:
•In the economic system, what is true of parts is not necessarily true
of the whole. The microeconomic behaviour cannot be added up to
derive the macroeconomic behaviour. Many problems and forces
affecting the economy as a whole cannot be fully understood by
analysing individual products and markets. It needs to be tackled at
the level of the whole economy.
By: Shuchi Goel 17

The following instances will make difference between micro and
macroeconomics clear:
i.It is possible for an individual to become richer by finding a few bundles of
thousand rupee notes but no nation can become richer by just printing more
currency notes.
ii.Saving is always a virtue for an individual. It helps him to accumulate wealth to
start or expand business, for purchasing durable goods like houses, cars, etc., for
education of children, for old age and so on. But, savings by all individuals may
prove to be vice for the economy especially under the conditions of depression and
unemployment caused by the deficiency of aggregate demand. Such collective
savings on the part of the individuals often result in contraction of demand, output,
employment and income. As a result the whole economy will suffer.
iii.An individual can buy more of a commodity at a given price. But if many
individuals try to buy more, the price would shoot up.
iv.An individual can close his account with the bank by withdrawing the entire
deposit. But, if all the depositors in the economy do so at the same time, banking
system will collapse.
By: Shuchi Goel 18

v.A cut in money wages at the time of depression and unemployment would
restrict or eliminate unemployment and depression. This conclusion of micro-
economics may be true for an individual industry. The reason is that at a lower
wage, more workers will be employed, given the demand curve for labour.
However, for the economy as a whole, this is highly misleading. Any attempt
to cut wages in the entire economy will bring down the aggregate demand for
goods and services in almost all the industries, as the wages are the incomes of
the workers. Moreover, the demand for labour is a derived demand, derived
from the demand of goods. The fall in aggregate demand for goods and
services will result in decline in demand for labour, which will create more
unemployment rather than reducing it.
vi.The aggregative conclusions show an average tendency and do not
influence all the sectors alike. Steady general price level rarely implies
equal distribution of income among various sections, viz. agriculturists,
industrialists, workers, consumers, etc. The high price in one sector
might have been neutralised by low price in other sector(s). (Cont..)
By: Shuchi Goel 19

It is, therefore, important to keep in mind the nature, composition and structure
of different sectors or groups when we make a statement regarding the system or
aggregates on the assumption that it is homogenous.

to produce in the economy
4. It helps to solve the central
problem of full employment of
resources in the economy

Microeconomics Macroeconomics

Conclusion
•Microeconomics is that branch of Economics which studies an economic or
decision making unit and considers in detail the behaviour of that particular
unit.
•Macroeconomics is concerned with the analysis of the economy as a
whole.
