Question

Explain briefly the net output (production) method or value-added method of estimating national income.

Answer 1

1. The Net Output Method, also known as the Production Method or Value-Added Method, is a method of estimating national income by calculating the value added by all productive sectors of the economy during a given year.
2. Under this method, the economy is divided into different sectors such as agriculture, industry, trade, and services.
3. For each sector, the total gross value of output is calculated by multiplying the quantity of goods and services produced by their market prices.
4. From this gross value, the value of intermediate goods used in production (like raw materials and fuel) is subtracted to avoid double-counting.
5. The result is the net value added by each sector. The total of all net value added figures gives the Net Domestic Product at Factor Cost (NDP at FC).
6. Finally, the Net Factor Income from Abroad (NFIA) is added to get the National Income (NNP at FC).
7. This method ensures an accurate estimate of national income by including only the value of final goods and services produced in the economy.
8. Formula of the value-added method:
   National Income (NNP at FC) = Gross Value of Output − Intermediate Consumption + Net Factor Income from Abroad

This method helps avoid double-counting and gives a clear picture of income generated through production in the economy.
