V. Write in detail answer


1. Briefly explain various terms associated with measuring of national income.

Gross National Product (GNP): Gross National Product is the total value of goods and services produced and income received in a year by domestic residents of a country. It includes profits earned from capital invested abroad.

Gross Domestic Product (GDP): Gross Domestic Product (GDP) is the total value of output of goods and services produced by the factors of production within the geographical boundaries of the country.

Net National Product (NNP): Net-National Product (NNP) is arrived by making some adjustment with regard to depreciation. We arrive at the Net National Product (NNP) by deducting the value of depreciation from Gross National Product.

(NNP = GNP – Depreciation)

Net Domestic Product (NDP): Net Domestic Product (NDP) is a part of Gross Domestic Product. Net Domestic Product is obtained from the Gross Domestic Product by deducting the quantum of tear and wear expenses (depreciation)

(NDP = GDP – Depreciation)

Per Capita Income (PCI):

• Per capita Income is an indicator to show the living standard of people in a country. It is obtained by dividing the National Income by the population of a country.

• Per capita Income = National Income / Population

Personal Income (PI): Personal income is the total money income received by individuals and households of a country from all possible sources before direct taxes.

Disposable Income (DI): Disposable income means actual income which can be spent on consumption by individuals and families. DPI = PI - Direct Taxes

2. What are the methods of calculating Gross Domestic Product? and explain its.

Expenditure Approach: In this method, the GDP is measured by adding the expenditure on all the final goods and services produced in the country during a specified period.

Y = C + I + G + (X-M)

The Income Approach: This method looks at GDP from the perspective of the earnings of the men and women who are involved in producing the goods and services. The income approach to measure GDP (Y) is Y = Wages + rent + interest + profit

Value Added Approach: Take a cup of tea. It is the final goods. The goods used to produce it, tea powder, milk and sugar are intermediate goods. To measure the market value of the cup of tea is to add the value of each intermediate goods used in the production of it. The sum of the value added by all the intermediate goods used in the production gives us the total value of the final goods produced in the economy.


Value Added method: Tea powder + Milk + Sugar = Tea

                 Value of inter mediate goods = Value of final goods

3. Write about the composition of GDP in India.

Indian economy is broadly divided into three sectors.

Primary Sector: (Agricultural Sector)

• Agricultural sector is known as primary sector, in which agricultural operations are undertaken.

• Agriculture based allied activities, production of raw materials such as cattle farm, fishing, mining, forestry, corn, coal etc. are also undertaken.

Secondary Sector: (Industrial Sector)

• Industrial sector is the secondary sector in which the goods and commodities are produced by transforming the raw materials.

• Important  industries are Iron and Steel industry, cotton textile, jute, sugar, cement, paper, petrochemical, automobile and other small scale industries.

Tertiary Sector: (Service Sector)

• Tertiary sector is known as service sector.

• It includes scientific research, transport, communication, trade, postal and telegraph, banking, education, entertainment, healthcare and information technology etc.

• In the 20th century, economists began to suggest that, traditional tertiary services could be further distinguished from 'quaternary' and 'quinary' service sectors.
