There are various concepts of National Income. The main concepts of NI are: GDP, GNP, NNP, NI, PI, DI, and PCI. These different concepts explain about the phenomenon of economic activities of the various sectors of the various sectors of the economy.
Gross Domestic Product (GDP)
The most important concept of national income is Gross Domestic Product. Gross domestic product is the money value of all final goods and services produced within the domestic territory of a country during a year.
Algebraic expression under product method is,
GDP=(P*Q)
where,
GDP=Gross Domestic Product
P=Price of goods and service
Q=Quantity of goods and service
denotes the summation of all values.
According to expenditure approach, GDP is the sum of consumption, investment, government expenditure, net foreign exports of a country during a year.
Algebraic expression under expenditure approach is,
GDP=C+I+G+(X-M)
Where,
C=Consumption
I=Investment
G=Government expenditure
(X-M)=Export minus import
GDP includes the following types of final goods and services. They are:
Consumer goods and services.Gross private domestic investment in capital goods.Government expenditure.Exports and imports.Gross National Product (GNP)
Gross National Product is the total market value of all final goods and services produced annually in a country plus net factor income from abroad. Thus, GNP is the total measure of the flow of goods and services at market value resulting from current production during a year in a country including net factor income from abroad. The GNP can be expressed as the following equation:
GNP=GDP+NFIA (Net Factor Income from Abroad)
or, GNP=C+I+G+(X-M)+NFIA
Hence, GNP includes the following:
Consumer goods and services.Gross private domestic investment in capital goods.Government expenditure.Net exports (exports-imports).Net factor income from abroad.
