Frequently Asked Questions
What is the difference between GDP at Market Price and GDP at Factor Cost?
GDP at Market Price includes indirect taxes and excludes subsidies, whereas GDP at Factor Cost measures the actual earnings of factors of production without taxes and subsidies. The relation is: GDP at MP = GDP at FC + Indirect Taxes - Subsidies.
Why are transfer payments excluded from National Income?
Transfer payments like scholarships, pensions, and gifts are unilateral payments where no corresponding goods or services are produced in exchange, hence they do not add to the current flow of production.
How do we avoid the problem of double counting in the Value Added Method?
Double counting is avoided either by taking the value of only final goods and services produced or by using the Value Added method at each stage of production rather than adding the gross output values.
