Answer:
Interdependence of macro-economics and micro-economics can be studies as follows:

Macro-economics and microeconomics depend on each other. Both are interdependent, macro economics contributes to the micro-economics. For example, the theory of investment belongs to micro-economics. It is derived from the behavior of the individual entrepreneur. The theory of aggregate investment function can also be derived from micro-economics theory of investment. Thus, we can say, that macro-economics depends on micro-economics.

2. Microeconomics depend on macro-economics:
Microeconomics depend upon macro-economics to a certain extent. For example, the rate of interest is a subject which belongs to micro-economics, but it is influenced by macro-economics aggregates. Thus, micro-economics depend upon macro-economics.

Conclusion:
Macro and micro-economics both are interdependent On each other. Neither is complete without the other. We must study macro-economics because it deals with average variables, such as national income and national output. We must study micro-economics because national output and national income are eventually the result of decision of millions of business firms and individuals. Thus, we can conclude that both are complementary to each other.

Question 8.
Calculate national income from the given data:

  1. Salary –  Rs. 6,000
  2. Rent – Rs. 2,000
  3. Profit – Rs. 2,000
  4. Interest – Rs. 1,000
  5. Consumption – Rs. 5,000.

Solution:
N.I. = Salary + Rent + Profit + Interest
= 6,000 + 2,000 + 2,000+ 1,000
N.I. = Rs. 11,000.

Question 9.
Calculate National Income on the basis of the given data by income method: Heads Rs. (in crores)

  1. Salary and wages = Rs. 18,000
  2. Interest = Rs. 7,000
  3. Depreciation = Rs. 4,000
  4. Rent = Rs. 6,000
  5. Profit = Rs. 25,000.

Solution:
National Income = Salary and wages + Interest +Rent +Profit
= Rs. 18,000 + Rs. 7,000 + Rs. 6,000 + Rs. 25,000 = Rs. 56,000.

Question 10.
On the basis of following data find out National Income by income method:

Solution:
National income (N.I.) = Salary and Wages + Rent + Profit + Interest
N.I. = 30,000 + 10,000 + 50,000 + 10,000
N.I. = Rs. 1,00,000.

National Income = Salary + Rent + Interest + Profit
= Rs. 60,000 + 20,000 + 10,000 + 20,000
= Rs. 1,10,000
National Income = Salary + Rent + Interest + Profit

Question 12.
Specify the relation of gross domestic product with welfare.
Answer:
Gross domestic product refers to money value of goods and services produced within the territorial boundaries of the country in a given year. With the increase in income consumption expenditure of a person increase which in turn increases material welfare. Therefore, it is not appropriate to relate GNP with welfare or their generalization may not be correct due to. following reasons:

1. GDP shows the total goods and services produced in the country. However, it does not exhibit the structure of the product if increase in GDP is mainly due to increased production of war equipment and ammunition. Then such an increase cannot be associated with any improvement in economic welfare.

2. If increase in GDP is due to rise in prices and not due to increase in physical output, then it will not be a reliable index of economic welfare.

3. GDP does not consider the changes in population of a country. If rate of population growth is higher than the rate of growth of GDP, then it will decrease per capital availability of goods and services, which will adversely affect the economic welfare.

What are the difficulties in estimating national income by income method?
Answer:
Estimation of national income by income method passes various difficulties. The major difficulties are:
(i) It is difficult to estimate mixed income. Mixed incomes are earned by an unincorporated sector and it is difficult to get reliable information from such unorganized sector.

(ii) Interest on national debt is not included in national income as per the national income convention on the assumption that government borrowings are used for consumption (unproductive) purposes. However, some economists object to this since, a part of the government borrowing is used for productive purposes.

(iii) Incomes received are generally calculated from income-tax returns. Therefore, income method is of limited used in underdeveloped countries because a very small part of the income earners are tax payers in these countries.
Income method of estimating national income is useful because it provides information about distribution of national income among various factor categories like share of wages profits etc. in national income.

Question 16.
What do you mean by G.D.P. at constant price?
Answer:
Gross Domestic Product at constant prices: Constant price means base year’s price. Base year is an average standard previous year in which major economic changes have not taken place. Goods and services produced during the year are either valued at constant price of the base year or the value of goods and services at current price is converted into the value at constant price.

Modem economies are inflationary economies where prices of goods and services are increasing at faster rates. It is therefore, advisable that the value of goods and services at current price should be converted at constant price, so that real Gross Domestic Product (G.D.P.) could be understood. Calculation at constant price should be referred as real G.D.P. Formula of conversion of G.D.P. at current price into G.D.P at constant price.

Question 17.
Will a profit maximizing firm in competitive market ever produce a positive level of output in the range where the marginal cost is falling? Give and explanation.
Answer:
A profit maximizing firm in a competitive market will produce a positive level at output in the same, where marginal cost is falling. Falling MC means that the cost of producing an additional unit of output trends to reduce. Here, price is constant as the firm is working in a competitive market in this case, the difference between firm’s total revenue and TVC (TVC = Σ MC) tends to increase. It means firm’s profit increases with the increase in the level of output. Then a competitive firm increase output when gross profit is rising.

Question 18.
From the following data, calculate Personal Income and Personal Disposable Income.
Items (₹ In cores )

  • Net domestic product at factor cost 8,000
  • Net factor income from abroad 200
  • Disbursed profit 1,000
  • Corporation tax 500
  • Interest received by households 1,500
  • Interest paid by households 1,200
  • Transfer income 300
  • Personal tax 500.

Solution:
Personal Income = (a) + (b) + (e – f) + (g) -(d)
= 8000 + 200 +(1500-1200)+ 300 – 500
= 8000 + 200 + 300 + 300 – 500
= 8800 – 500 = ₹ 8,300 Cores.
Personal Disposable Income = Personal Income – Personal Tax
= 8300 – 500 = ₹ 7,800 Croce.

Question 19.
In a single day, Raju, the barber, collects ₹ 500 from hair cuts. Over this day, his equipment depreciates in value by ₹ 50, of the remaining ₹ 450, Raju pays sales tax worth ₹ 30, takes home ₹ 200 and retains ₹ 220 for improvement and buying of new equipment He further pays 120 as income tax from his income. Based on this information, complete Raju’s contribution to the following measures of income:

(a) Gross domestic product
(b) NNP at market price
(c) NNP at factor cost
(d) Personal income
(e) Personal disposable income.

Answer:
(a) GDP = ₹500

(b) NNPMP=GDP – DeP
₹500 – ₹ 50 = ₹450

(c) NNfc = NNP – Sales tax
= ₹450 – ₹30 = ₹420

(d) PI = NNPfc – Retained earnings
= ₹ 420 – ₹ 220
= ₹ 200

(e) PDI = PI – Income tax
=₹ 200 – ₹ 20
= ₹ 180.
