GDP=(P*Q) Were,
 GDP=Gross Domestic
Product
 P=Price of goods and
service
 Q=Quantity of goods and
service
GDP=C+I+G+(X-M) Were,
 C=Consumption
 I=Investment
 G=Government expenditure
 (X-M) =Export minus import

10. 2. Gross National Product (GNP)
GNP=GDP+NFIA (Net Factor Income from Abroad)
or, GNP=C+I+G+(X-M) +NFIA
Hence, GNP includes the following:

 Gross private domestic investment in capital goods.
 Government expenditure.
 Net exports (exports-imports).
 Net factor income from abroad.

 NI = NNP + Subsidies - Interest Taxes

 Personal Income is the total money income
received by individuals and households of a
