GNP (gross national product)

GDP (q.v.) plus the net income or loss stemming from transactions with foreign countries. GNP is the broadest measurement of the output of goods and services by an economy. It can be calculated at market prices, which include indirect taxes and subsidies. Because indirect taxes and subsidies are only transfer payments, GNP is often calculated at a factor cost, removing indirect taxes and subsidies.
