National Income Committee of India (1951) defines National Income as follows:
“ A national income estimate measures the volume of commodities and services turned out during a given period counted without duplication.”
Thus, National income is the aggregation of wages, rent, interest and profit or is the total of rewards to be given to the factors of production for any certain period.
CONCEPTS OF NATIONAL INCOMEGross Domestic Product- GDPGross National Product- GNPNet National Product-NNPPersonal Income- PIDisposable Personal Income-DPIPer Capita Income-PCI
Gross Domestic Product - GDPGross domestic product (GDP) is a measure
of the income and expenditures of an economy.
It is the total market value of all final goods and services produced within a country in a given period of time.
It includes both tangible goods (food, clothing, cars) and intangible services (haircuts, housecleaning, doctor visits).
Gross National Product - GNP
Gross national product (GNP) is the total income earned by a nation’s permanent residents (called nationals).
It differs from GDP by including income that our citizens earn abroad and excluding income that foreigners earn here.
GNP=GDP+X-M
Net National Product - NNP
Net National Product (NNP) is the total income of the nation’s residents (GNP) minus losses from depreciation.
NNP=GNP-Depreciation
Personal Income - PI Income earned by all the individuals and
institutions during a year in a country. The entire national income does not reach individuals and institutions. A part of it goes by way of corporate taxes .
PI = National Income –(Corporate taxes, undistributed profits, social security contributions) + Transfer Payments.
Disposable Personal Income - DPI Disposable personal income is the income that
household and non corporate businesses have left after satisfying all their obligations to the government.
Disposable personal income = Personal Income - Direct Taxes
Per capita Income - PCI If the national income is divided by the total
population we get the per capita income.
National Income = C + I + G + (X – M)
where C = Consumption, I = Investment, G = Government and X is Export and M is Import.
