Market and Its Types

Economists understand by the term market not any particular market place in which things are bought and sold, but the whole of any region in which buyers and sellers are in such free dealing with each other that the
price of the same goods tend to equality easily and quickly.

1. Perfect Competition

2. Imperfect Competition

National Income

The average achievement of a country is measured with respect to growth rate of its National Income. National Income refers to the aggregate value of goods and services produced in an economy in one year.

National Income is defined as the total net earnings from  the production of goods and services in a country over a period of time, usually one year and consisting essentially of wages, salaries, rents, profits and interests.

Dadabhai Naoroji was the pioneer in this field. He prepared the first estimates of National Income in 1876.
However, the first person to adopt a scientific procedure in estimating the National Income was Dr VKRV Rao in 1931.

The Government of India appointed National Income Committee in 1949 which presented its first report in
1951. Since 1955 the National Income estimates are being prepared by Central Statistical Organisation
(CSO).

The CSO uses different methods like the Product Method, Income Method, out put method and  Expenditure Method for various sectors in the process of estimating the National Income.

Expenditure Method for Calculating National Income

The expenditure method measure the national Income as the sum total of expenditures made by individuals on personal consumption, firms on private investment and government authorities on government purchases.

In monetary terms its measure are

1. GDP (Gross Domestic Product)

2. NDP(National Domestic Product)

3. GNP (Gross National Product)

4. NNP (Net National Product) 

                    Domestic Product = Domestic Income and National
                                      Product = National Income.
1. GDP (Gross Domestic Product) It is the total market value of all final goods and services produced during
a given time period within a nations’ domestic border.
                     GDP =C+I+G + NX
         where C = can sumption; I = Investment
           G=Government expenditure
                     NX = Net Export


2. NDP (National Domestic Product) Net Domestic Product equals the GDP minus depreciation where depreciation is a reduction in the value of an asset over time.

                                      NDP = GDP – Depreciation
                                  NI = NDP + Net Foreign Income


3. GNP (Gross National Product) Gross National Product equals the GDP plus Net Factor Income from Abroad (NFIA). NFIA is basically any income earned by residents from overseas investment minus income earned within the domestic economy.


                 GNP = GDP + Net factor income from Abroad (NFIA)


4. NNP (Net National Product) Net National Product equals the GDP minus depreciation and plus Net
Factor Income from Abroad. It is also known as National Income.


                                       NNP = GNP – Depreciation
