4. Answer the following:
Question 1.
Explain the features of Micro economics.
OR
Explain the characteristics or nature of micro economics.
Answer:
Features of Micro Economics :
- Based on certain ssumption : Micro economics is based on ‘ceteris paribus’ assumption i.e., other things remaining constant like full employment, laissez faire policy, perfect competition, pure capitalism, etc.
- Study of Individual units : Micro economics deals with the study of behaviour of small individual units of the economy such as individual units of the economy such as individual consumer, individual firm, individual industries, individual prices, etc.
- Slicing Method : It divides or slices the economy into small units and studies each unit in detail e.g. study of a particular household demand in detail.
- Analysis of Market Structures : Micro economics analyses different market structures such as perfect competition, monopoly, monopolistic competition, oligopoly, etc.
- Use of Marginalism Principle : The term ‘marginal’ means change brought in total by an additional unit. Marginal analysis helps to study a variable through the changes by which producers and consumers take economic decisions using this principle.
- Price Theory : Micro economics is known as price theory because it determines the prices of goods and services as well as prices of factors of production.
- Limited Scope : The study of micro economics is limited to individual economic unit only. It does not deal with macro problems like unemployment, inflation, deflation, poverty, unemployment, population, etc.
- Partial I quilibrium : Micro economics analysis deals with partial equilibrium which analyses equilibrium position of an individual economic unit i.e. individual consumer, individual firm, etc.
Question 2.
Explain the importance of Macro economics.
Answer:
Importance of Macro Economics :
- Functioning of an Economy : It gives an idea of functioning of an economic system and help us to understand the behavioural pattern of aggregate variables.
- Economic fluctuations : It helps to analyse the causes of fluctuation in income, output and employment.
- National Income : It helps to study about National Income and makes possible to formulate correct economic policies.
- Economic Development : It helps us to understand the problems of the developing countries such as poverty, difference in the standards of living, etc., and suggest important steps to achieve economic development.
- Performance of an Economy : It helps us to analyse the performance of an economy where National Income estimates are used to measure the same.
- Study of Macro-economic Variables :
Study of macro economic variables are important to understand the working of the economy. - Level of Employment : Macro economics helps to analyse the general level of employment and output in an economy.

Question 3.
Explain the scope of Macro economics.
OR
“Scope of Macro Economics is wide.” Explain.
OR
Macro Economics is comprehensive in nature.
OR
Explain the subject matter of macro economics.
Answer:
Scope of Macro Economics:
The given chart helps us to understand the scope of macro economics.
1. Theory of Income and Employment : It explains which factors determine the level of National Income and employment and what j causes fluctuations in the level of income, output and employment.
To understand how the level of employment is determined, we have to study the consumption function. It includes theory of business cycles.
2. Theory of General Price Level and Inflation: Macro economics analyses shows how the general price level is determined and the causes for fluctuations in it. This study is important for understanding the problems created by inflation and deflation.
3. Theory of Economic Growth and Development : Macro economics studies the causes of under development and poverty in poor countries and suggests strategies for accelerating growth and development in the country.
4. Macro theory of Distribution : Macro theory of distribution deals with the relative share of rent, wages, interest and profit in j the total national income of various classes.
5. State with reasons whether you agree or disagree with the following statements:
Question 1.
The scope of micro economics is unlimited.
Answer:
No, I do not agree with this statement.
- Micro economics deals with small or individual units.
- Micro economics is the study of particular firm, particular household, individual prices, wages, incomes, individual industries, particular commodities.
- Micro economics deals with small part of National economy. It does not deal with whole economy like National income, Aggregate demand, Aggregate supply, poverty, inflation, etc.
- Hence, the scope of micro economics is limited.
Question 2.
Macro economics deals with the study of individual behaviour.
OR
Macro economics studies small units.
Answer:
No, I do not agree with this statement.
OR
Macro Economics is the study of I aggregate.
OR
Macro economics is concerned with macro economic variables.
Yes, I agree with this statement.
- Macro Economics studies the behaviour ofthe economy as a whole and not individual behaviour.
- It studies about larger economic units or aggregate economic variables like aggregate demand, aggregate supply, total investment, total savings, total employment, etc.
- It studies the general price level and macro theory of distribution.
- Whereas Micro Economics deals with individual behaviour of the people in the economy. It studies about individual demand, market demand, individual income, price of particular commodity etc.
- According to Prof. Kenneth E. Boulding “Macro Economics deals not with individual; quantities as such, but with aggregates of these quantities, not with individual income but with National Income, not with individual prices but with general price level, not with individual output but with National Output.

Question 3.
Macro economics is different from micro economics.
OR
Macro economics is wider than Micro economics.
OR
There is difference between micro economics and macro economics.
Answer:
Yes, I agree with this statement.
- Micro economics is a study of a particular unit of an economy. On the other hand macro economics is the study of entire economy.
- Micro economics studies individual demand, individual supply, individual income, price determination of particular product, etc. On the other hand macro economics studies aggregate demand, aggregate supply, national income, etc.
- Micro economics follows partial equilibrium analysis and macro economics follows general equilibrium analysis.
- Micro economics uses slicing method for study of small unit and macro economics uses lumping method for study of large unit.
- Therefore, macro economics is different from micro economics.
Question 4.
Micro economics uses slicing method.
Answer:
Yes, I agree with this statement.
- Micro economics deals with small or individual units.
- Micro economics divides or slices the economy into small units and studies each unit in detail.
- It is concerned with microscopic study of these units.
- It is the study of particular firm, particular household, individual prices, wages, incomes, etc.
- Hence, micro economics uses slicing method.
Question 5.
Micro economics is known as Income theory.
Answer:
No, I do not agree with this statement.
OR Micro economics is also known as price theory.
Yes, I agree with this statement.
- Micro Economics is known as ‘Price Theory’.
- The scope of micro economics includes the study of product pricing and factor pricing.
- The theory of product pricing explains how the price of food grains, vegetables, clothes, etc., are determined.
- They are determined by the interaction of market demand and supply forces.
- The theory of factor pricing explains the distribution of factor income such as rent on land, wages to labourers, interest on capital and profit to entrepreneurs.
- The factor prices are also determined by the demand and supply forces.
- Therefore, Micro Economics is also known as ‘Price Theory’.
