GNP = GDP + NFI (Net Factor Income)
NFI = factor income received - factor income paid
So, if NFI equals zero, GDP = GNP
NFI is negative, GDP > GNP
NFI is positive, GDP < GNP
GDP = NDI at factor cost + indirect taxes + depreciation –
subsidy
Depreciation: is wear and tear of capital.
Note: subsidies can be considered as negative taxes so,
Net indirect taxes = indirect taxes – subsidies
National Income or Net Domestic Income at Factor Cost (NDI).
Net Domestic Income (NDI) = Compensation of Employees +
Rental Income + Net interest + Corporate Profit + Proprietor's
Income.
Factor cost is the cost of factors of production used to produce
final goods and services.
To calculate GDP using market value we must add Net Indirect
Tax (NIT) and Depreciation:
GDP = NDI + net indirect tax (NIT) +Depreciation (D)
Net indirect tax = Indirect Tax – Subsidies
Indirect tax is a tax paid by consumers when they buy goods and
services. Because of indirect taxes consumers pay more for the
goods and services than producers receive ⇒ market price >
factor cost.
Subsidy is a payment made by a government to a producer.
Because of subsidies consumers pay less for some goods and
services than producers receive ⇒ factor cost > market price
Depreciation is the decrease in the capital stock because of the
wearing out of machines and equipments (is the consumption of
the capital). It is treated as a cost of production and is subtracted
in calculation NDI. So it must be added back to get the GDP.
Gross and Net Domestic Product:
“Gross” means before accounting for the depreciation of capital.
“Net” means after accounting for the depreciation of capital.
Net domestic product = GDP – Depreciation
Other National Concepts:
Per Capita GDP = GDP / Population in the economy
Net Domestic Product (NDP) = GDP – Depreciation
National Income (NI) = NDP + Net Income Earned Abroad –
Indirect Business Taxes
Personal Income (PI) = NI – Corporate Income Taxes +
Undistributed Profits – Social Security + Transfer Payments
(Public and Private)
Disposable Income (DI) = PI – Personal Income Taxes
Disposable income (DI) = Consumption (C) + Savings (S)
Examples:
1.
(a) A country had C equal to $1 billion, G equal to $700 million, I equal to $500 million,
and imports were $200 million less than exports, what was the country's GDP?
GDP=C+G+I+(X-M)
1+0.7+0.5+0.2=2.4
(b) A country had C equal to $1 billion, G equal to $700 million, I equal to $500 million, and
imports were $300 million more than exports, what was the country's GDP?
GDP=C+G+I+(X-M)
=1+0.7+0.5-0.3=1.9
2. A country had the following data: income (Y) = $200,000, taxes (T) = $60,000, government
purchases (G) = $45,000, consumption (C) = $120,000, exports (X) = $65,000 and imports (M) =
$70,000.
a. What was the country's private saving or households and businesses saving?
Y=C+S+T→S=Y-C-T→S=200-120-60=20,000
b. What was the government saving (or government surplus)?
GS= T-G=60-45=15,000
c. What was the national saving?
NS=PS+GS=20+15=35,000
PS= NS - GS
d. Is the country lending or borrowing from the rest of the world and by how much?
X-M=60-70= -5,000
e. What was the country's investment?
I=PS+ GS+ borrow=20+15+5=40,000
f. How much investment is financed by national saving and how much investment is financed by
the lending or borrowing from the rest of the world?
35+5 borrowing

Referring to the table above:
3.1. What was the country's net domestic product (NDP)?
(a) 2435
