National Income
1. Definition: National income refers to the total value of all goods and services produced
within a country's borders in a specific time period, typically a year.

2. Measurement: There are three primary methods to calculate national income: a. Production
Approach: Summing up the value of all goods and services produced. b. Income Approach:
Summing up all the incomes earned, including wages, rents, interests, and profits. c.
Expenditure Approach: Summing up all the spending in the economy, including
consumption, investment, government spending, and net exports (exports minus imports).

Components of National Income:

1. Gross Domestic Product (GDP): The total value of all goods and services produced within a
country's borders, regardless of who owns the productive assets.

2. Gross National Product (GNP): The total value of all goods and services produced by a
country's residents, both domestically and abroad, minus the value of production by foreign
residents within the country.

3. Net National Product (NNP): GNP minus depreciation (wear and tear on capital goods).

4. Personal Income: The total income earned by individuals, including wages, interest, rent,
and transfer payments like Social Security.

5. Disposable Income: Personal income minus personal taxes. It represents the income
available for consumption and savings.

Importance of National Income:

1. Economic Performance: National income measures the overall economic performance of a
country, indicating whether an economy is growing, contracting, or stable.

2. Standard of Living: It provides insights into the standard of living of the population. Higher
national income per capita generally correlates with a better standard of living.

3. Policy Planning: Governments use national income data to formulate economic policies,
allocate resources, and make informed decisions.

4. Comparative Analysis: It allows for comparisons between countries' economic performance
and helps identify areas that require improvement.

Limitations:

1. Non-Market Transactions: National income calculations may not account for non-market
activities, like household production and the informal sector.

2. Quality of Life: National income doesn't directly measure the quality of life, as it focuses on
economic production.

3. Distributional Issues: It doesn't provide information on income distribution, which can be
highly unequal in some countries.

4. Environmental Impact: National income doesn't consider the environmental costs of
economic activities.
