Chapter 2 National Income
Introduction
National Income provides a comprehensive measure of the economic activities of a nation. It denotes the country’s purchasing power. The growth of an economy is measured by the rate at which its real national income grows over time. National income thus serves as an instrument of economic planning. Further, national income is one of the most significant macroeconomic variables. Thus, a clear understanding of the meaning, concepts, measurement and uses of national income is essential. Nobel laureate Simon Kuznets first introduced the concept of national incoIncome

Answer the following questions in one or two sentences.
21. Define National Income.
- National Income means the total money value of all final goods and services produced in a country during a particular period of time (one year).
22. Write the formula for calculating GNP.
- GNP at market prices means the gross value of final goods and services produced annually in a country plus net factor income from abroad
- (C + I + G + (X – M) + (R – P)).
23. What is the difference between NNP and NDP?
NNP:
- NNP refers to the market value of output.
- NNP at factor cost is the total of income payment made to factors of production.
NDP:
- NDP is the value of net output of the economy during the year
- The country’s capital equipment wears out of becomes outdated each year during the production process.
24. Trace the relationship between GNP and NNP.
GNP:
- 1. Total money value of final goods and services produced in a country during a particular year (one year).
NNP:
- 1. Total money value of final goos and services produced in a country in a country during a particular year (one year).
25. What do you mean by the term ‘Personal Income’?
- Personal income is the total income received by the individuals of a country from all sources before payment of direct taxes in a year.
26. Define GDP deflator.
- GDP is the total market value of final goods and services produced within the country during a year. This is calculated at market prices and is known as GDP at market prices.
- Thus GDP by expenditure method at market prices
- = C + I + G + (X – M)Where C – consumption goods;
G – Government purchases;
(X – M) is net export which can be positive or negative.
27. Why is self consumption difficult in measuring national income?
- Farmers keep a large portion of food and other goods produced on the farm for self consumption.
- The problem is whether that part of the produce which is not sold in the market can be included in national income or not.

Answer the following questions in one Paragraph.
28. Write a short note on per capita income.
Per Capita Income:
- The average income of a person of a country in a particular year is called Per Capita Income.
- Per capita income is obtained by dividing national income by population.
29. Differentiate between personal and disposable income.
Personal income:
- Personal income is the total income received by the individuals of a country from all sources before payment of direct taxes in a year.
Disposable income:
- Disposable Income is also known as Disposable personal income. It is the individuals income after the payment of income tax. This is the amount available for households for consumption
30. Explain briefly NNP at factor cost.
- Net National Product refers to the value of the net output of the economy during the year. NNP is obtained by deducting the value of depreciation, or replacement allowance of the capital assets from the GNP. It is expressed as, NNP = GNP – depreciation allowance.
31. Give short note on Expenditure manalysis.
- The total expenditure incurred by the society in a particular year is added together.
- To calculate the expenditure of a society, it includes personal consumption expenditure, net domestic investment, government expenditure on consumption as well as capital goods and net exports.
32. What is the solution to the problem of double counting in the estimation of national income?
- The value obtained is actually the GNP at market prices. Care must be taken to avoid double counting.
- The value of the final product is derived by the summation of all the values added in the productive process.
- To avoid double counting, either the value of the final output should be taken into the estimate of GNP or the sum of values added should be taken.
- Double counting is to be avoided under value added method.
- Any commodity which is either raw material or intermediate good for the final production should not be included.
- For example, value of cotton enters value of yam as cost, and value of yam in cloth and that of cloth in garments.
- At every stage value added only should be calculated.
33. Write briefly about national income and welfare.
National Income and Welfare:
- National Income is considered as an indicator of the economic wellbeing of a country. The per capita income as an index of economic welfare suffers from limitations which are stated below:
- The economic welfare depends upon the composition of goods and services provided. The greater the proportion of capital goods over consumer goods, the improvement in economic welfare will be lesser.
- Higher GDP with greater environmental hazards such as air, water and soil pollution will be little economic welfare.
- The production of war goods will show the increase in national output but not welfare.
- An increase in per capita income may be due to employment of women and children or forcing workers to work for long hours. But it will not promote economic welfare.
34. List out the uses of national inincome
The following are some of the concepts used in measuring national income!
GDP:
- GDP is the total market value of final goods and services produced within the country during a year.
- This is calculated at market prices and is known as GDP at market prices. Thus GDP by expenditure method at market
prices = C + I + G + (X-M)
Where C – Consumption goods;
I – Investment goods;
G – Government purchases;
(X – M) is net export which can be positive or negative.
Net National Product (NNP) (at Market price):
- Net National Product refers to the value of the net output of the economy during the year.
- NNP is obtained by deducting the value of depreciation, or replacement allowance of the capital assets from the GNP. It is expressed as,
NNP = GNP – depreciation allowance.
NNP at Factor cost:
- NNP refers to the market value of output.
- NNP at factor cost is the total of income payment made to factors of production.
Personal Income:
- Personal income is the total income received by the individuals of a country’ from all sources before payment of direct taxes in a year.
Per Capita Income:
- The average income of a person of a country in a particular year is called Per Capita Income.
- Per capita income is obtained by dividing national income by population.
Disposable Income:
- Disposable Income is also known as Disposable personal income.
- It is the individuals income after the payment of income tax.
- This is the amount available for households for consumption.
Real Income:
- Nominal income is national income expressed in terms of a general price level of a particular year in other words, real income is the buying power of nominal income.
GDP deflator:
- GDP deflator is an index of price changes of goods and services included in GDP.
- It is a price index which is calculated by dividing the nominal GDP in a given year by the real GDP for the same year and multiplying it by 100.

Answer the following questions in about a page.
35. Explain the importance of national income.
- National income is of great importance for the economy of a country. Nowadays the national income is regarded as accounts of the economy, which are known as social accounts. It enables us:
- 1. To know the relative importance of the various sectors of the economy and their contribution towards national income; from the calculation of national income, we could find how income is produced, how it is distributed, how much is spent, saved or taxed.
- 2. To formulate the national policies such as monetary policy, fiscal policy and other policies; the proper measures can be adopted to bring the economy to the right path with the help of collecting national income data.
- 3. To formulate planning and evaluate plan progress; it is essential that the data pertaining to a country’s gross income, output, saving and consumption from different sources should be available for economic planning.
- 4. To build economic models both in short – run and long – run.
- 5. To make international comparison, inter – regional comparison and inter – temporal comparison of growth of the economy during different periods.
- 6. To know a country’s per capita income which reflects the economic welfare of the country (Provided income is equally distributed)
- 7. To know the distribution of income for various factors of production in the country.
- 8. To arrive at many macro economic variables namely, Tax – GDP ratio, Current Account Deficit – GDP ratio, Fiscal Deficit – GDP ratio, Debt – GDP ratio etc.
36. Discuss the various methods of estimating the national income of a country.
- There are three methods that are used to measure national income.
1)Production or value added method
2)Income method or factor earning method
3)Expenditure method
And if these methods are done correctly, the following equation must hold
Output = Income = Expenditure
- This is because the three methods are circular in nature. It begins as production, through recruitments of factors of production, generating income and going as incomes to factors of production.
Product Method:
- Product method measures the output of the country. It is also called inventory method. Under this method, the gross value of output from different sectors like agriculture, industry, trade and commerce, etc., is obtained for the entire economy during a year. The value obtained is actually the GNP at market prices. Care must be taken to avoid double counting.
Income Method (Factor Earning Method):
- This method approaches national income from the distribution side. Under this method, national income is calculated by adding up all the incomes generated in the course of producing national product.
- National income is calculated as domestic factor income plus net factor incomes from abroad. In short,
Y = w + r + i + π + (R – P)
w = wages, r = rent, i = interest, n = profits,
- This method is adopted for estimating the contributions of the remaining sectors, viz., small enterprises, banking and insurance, commerce and transport, professions, liberal arts and domestic service, public authorities, house property and foreign sector transaction.
The Expenditure Method (Outlay method): \
- The total expenditure incurred by the society in a particular year is added together. To calculate the expenditure of a society, it includes personal consumption expenditure, net domestic investment, government expenditure on • consumption as well as capital goods and net exports. Symbolically,
GNP = C + I + G + (X – M)
C – Private consumption expenditure
I – Private Investment Expenditure
G – Government expenditure
X – M = Net exports
37. What are the difficulties involved in the measurement of national income?
Difficulties in Measuring National Income:
- In India, a special conceptual problem is posed by the existence of a large, unorganised and non-monetised subsistence sector where the barter system still prevails for transacting goods and services.
- Here, a proper valuation of output is very difficult.
Transfer payments:
- Government makes payments in the form of pensions, unemployment allowance, subsidies, etc. These are government expenditure.
- But they are not included in the national income.
- Because they are paid without adding anything to the production processes.
- During a year, Interest on national debt is also considered transfer payments because it is paid by the government to individuals and firms on their past savings without any productive work.
Difficulties in assessing depreciation allowance:
- The deduction of depreciation allowances, accidental damages, repair and replacement charges from the national income is not an easy task.
- It requires high degree of judgment to assess the depreciation allowance and other charges.
Unpaid services:
- A housewife renders a number of useful services like preparation of meals, serving, tailoring, mending, washing, cleaning, bringing up children, etc.
- She is not paid for them and her services are not directly included in national income.
Income from illegal activities:
- Income earned through illegal activities like gambling, smuggling, illicit extraction of liquor, etc., is not included in national income.
- Such activities have value and satisfy the wants of the people but they are not considered as productive from the point of view of society.
Production for self-consumption and changing price:
- Farmers keep a large portion of food and other goods produced on the farm for self consumption.
- The problem is whether that part of the produce which is not sold in the market can be included in national income or not.
Capital Gains:
- The problem also arises with regard to capital gains.
- Capital gains arise when a capital asset such as a house, other property, stocks or shares, etc. is sold at higher price than was paid for it at the time of purchase.
- Capital gains are excluded from national income.
Statistical problems:
- There are statistical problems, too. Great care is required to avoid double counting. Statistical data may not be perfectly reliable, when they are compiled from numerous sources.
- Skill and efficiency of the statistical staff and cooperation of people at large are also equally important in estimating national income.
38. Discuss the importance of social accounting in economic analysis
National Income and Social Accounting:
National income is also being measured by the social accounting method.
Under this method, the transactions among various sectors such as firms, households, government, etc., are recorded and their interrelationships traced.
The social accounting framework is useful for economists as well as policy makers, because it represents the major economic flows and statistical relationships among various sectors of the economic system.
It becomes possible to forecast the trends of economy more accurately.
Social Accounting and Sector:
Under this method, the economy is divided into several sectors.
A sector is a group of individuals or institutions having common interrelated economic transactions.
The economy is divided into the following sectors:
Firms
Households
Government
Rest of the world and
Capital sector.
“Firms” undertake productive activities. Thus, they are all organizations which employ the factors of production to produce goods and services.
“Households” are consuming entities and represent the factors of production, who receive payment for services rendered by them to firms. Households consume the goods and services that are produced by the firms.
“The Government sector” refers to the economic transactions of public bodies at all levels, centre, state and local.
The main function of the government is to provide social goods like defence, public health, education, etc.
“Rest of the world sector” relates to international economic transactions of the country. It contains income, export and import transactions, external loan transaction, and allied overseas investment income and payments.
“Capital sector” refers to saving and investment activities. It includes the transactions of banks, insurance corporations, financial houses, and other agencies of the money market.
