National Income Definition and Calculation

Definition of National Income

• National income is the total income earned by a country's residents, including individuals, businesses, and governments, within a specific period of time, usually a year.

Methods of Calculating National Income

• There are three main methods to calculate national income:
  1. Production Approach: Adds up the value of all goods and services produced within a country.
  2. Expenditure Approach: Calculates the total amount spent by households, businesses, government, and foreigners on goods and services.
  3. Income Approach: Calculates the total income earned by households and businesses.

Components of National Income

• Gross National Product (GNP): The total value of all goods and services produced by a country's residents, including income earned abroad.
• Gross Domestic Product (GDP): The total value of all goods and services produced within a country's borders.
• Net National Product (NNP): GNP minus depreciation.
• Net Domestic Product (NDP): GDP minus depreciation.

National Income Accounting Identities

• GNP = C + I + G + (X - M): Where C is consumption, I is investment, G is government spending, X is exports, and M is imports.
• GDP = C + I + G + (X - M): Same as above, but for domestic production.

Importance of National Income

• National income is used to measure a country's economic performance and growth.
• It helps policymakers make informed decisions about taxation, government spending, and monetary policy.
• It provides a basis for international comparisons of economic performance.
