Frequently Asked Questions
What is the difference between Domestic Income and National Income?
Domestic income (NDPfc) is generated within the domestic territory of a country by all producers, whereas National income (NNPfc) is earned by the normal residents of a country, regardless of where it is earned, by adding NFIA to domestic income.
How do we avoid the problem of double counting in the Value Added method?
Double counting is avoided either by taking only the value added by each firm (Value of Output minus Intermediate Consumption) or by considering the final value of only final goods and services, ignoring intermediate goods.
Are transfer payments included in National Income?
No, transfer payments like scholarships, old-age pensions, and pocket money are not included in national income because they do not correspond to any productive service or value addition in the economy.
