Concept of National Income
Concept of National Income
National income
means the value of goods and services produced by a country during a financial year. Thus, it is the net result of all
economic activities of any country during a period of one year and is valued in
terms of money. National income is an uncertain term and is
often used interchangeably with the national dividend, national output, and
national expenditure. We can understand this concept by
understanding the national income definition.
The
National Income is the total amount of income accruing to a
country from economic activities in a years’ time. It includes
payments made to all resources either in the form of wages, interest, rent, and profits.
The progress of a
country can be determined by the growth of the national income of the country

Definition
There are two
National Income Definition
·
Traditional Definition
·
Modern Definition
According to Marshall:
“The labor and capital of
a country acting on its natural resources produce annually a certain net
aggregate of commodities, material and immaterial including services of all
kinds. This is the true net annual income or revenue of the country or national
dividend.”
The definition as
laid down by Marshall is being criticized on the following grounds.
Due to the varied
category of goods and services, a correct estimation is very
difficult.
There is a chance of
double counting, hence National Income cannot be estimated correctly.
For example, a product runs in the supply from the producer to
distributor to wholesaler to retailer and then to the ultimate consumer. If on
every movement commodity is taken into consideration then the value of National
Income increases.
Also, one other
reason is that there are products which are produced but not marketed.
For example, In an agriculture-oriented country like India, there are
commodities which though produced but are kept for self-consumption or
exchanged with other commodities. Thus there can be an underestimation of
National Income.
Following are the Modern National Income definition

GDP
·
GNP
Gross Domestic Product
The total value of
goods produced and services rendered within a country during a year is its Gross Domestic Product.
Further, GDP is
calculated at market price and is defined as GDP at market prices. Different
constituents of GDP are:
1. Wages and salaries
2. Rent
3. Interest
4. Undistributed profits
5. Mixed-income
6. Direct taxes
7. Dividend
8. Depreciation
Gross National Product
For calculation of GNP, we need to collect and assess
the data from all productive activities, such as
agricultural produce, wood, minerals, commodities, the contributions to
production by transport, communications, insurance companies, professions such
(as lawyers, doctors, teachers, etc). at market prices.
It
also includes net income arising in a country from abroad. Four main
constituents of GNP are:
1. Consumer goods and services
2. Gross private domestic income
3. Goods produced or services rendered
4. Income arising from abroad.
GDP and GNP on the basis
of Market Price and Factor Cost
a) Market Price
The Actual transacted
price including indirect taxes such as GST, Customs duty etc. Such taxes tend
to raise the prices of goods and services in the economy.
b) Factor Cost
It Includes the cost
of factors of production e.g. interest on capital, wages to labor, rent for
land profit to the stakeholders. Thus services provided by service providers
and goods sold by the producer is equal to revenue price.
Alternatively,
Revenue Price (or
Factor Cost) = Market Price (net
of) Net Indirect Taxes
Net Indirect Taxes =
Indirect Taxes Net of Subsidies received
Hence,
Factor Cost
shall be equal to
(Market Price) LESS
(Indirect Taxes ADD Subsidies)
Net Domestic Product
The net output of the
country’s economy during a year is its NDP. During the year a country’s capital
assets are subject to wear and tear due to its use or can become obsolete.
Hence, we deduct a
percentage of such investment from the GDP to arrive at NDP.
So NDP=GDP at factor cost LESS Depreciation.
The Accumulation of
all factors of income earned by residents of a country and includes income
earned from the county as well as from abroad.
Thus, National Income
at Factor Cost shall be equal to
NNP at Market Price LESS (Indirect Taxes ADD Subsidies)
