What is National Income ?
National income :
The monetary value of the final goods and services produced by an economy over a period of time - usually one year, although figures may be produced on a quarterly basis.
National Income Accounting :
A set of rules and definitions for measuring economic activity in the aggregate economy – that is, in the economy as a whole.
GDP and GNP
Gross Domestic Product (GDP) :
- The total market value of all final goods and services produced in an economy in a one-year period.
- GDP measures the economic activity that occurs within a country.
Gross National Product (GNP) :
- The aggregate final output of citizens and businesses of an economy in one year.
- GNP measures the economic activity of the citizens and businesses of a country.

Ways to Eliminating Intermediate Goods
- Calculate only final sales
- Value added approach
Example of Value Added Approach Eliminates Double Counting :
Formula to Calculate Net Domestic Product (NDP) and National Income
- Net Domestic Product, NDP = GDP - Depreciation
- National Income = NDP - Indirect taxes
GDP Deflator
- an average of current prices expressed as a percentage of base year prices.
- GDP Deflator measures the price level.
- The higher the nominal GDP for a given real GDP, the higher the GDP Deflator, i.e., the higher are the prices.
2 Methods of Calculating
1. Expenditure Approach
- GDP = C + I + G + (X - M) where
C = consumption
I = Investment
G = Government expenditure
X = Export of goods and services
M = Import of goods and services
(X-M) = Net export of goods and services
