Meaning of National Income
National income accounting measures economic activity and income using defined macroeconomic concepts.
GDP, GNP, NDP and NNP
GDP measures final production within domestic territory. GNP adjusts GDP for net factor income from abroad. NDP subtracts depreciation from GDP, while NNP makes the corresponding adjustment to GNP.
Measurement Methods
The broad approaches are value added, income and expenditure methods. They examine production, factor incomes and spending from different sides of economic activity.
Value Added Method
This method avoids double counting by measuring value added at successive production stages. Students must distinguish intermediate goods from final goods.
Income Method
The income approach considers relevant factor incomes generated through production, such as compensation, rent, interest and profits, within the applicable accounting framework.
Expenditure Method
The expenditure approach aggregates spending on final goods and services through relevant consumption, investment, government expenditure and net exports components.
Why It Matters
National income statistics help analyse growth, production, living standards and economic policy.
Exam Tip
Remember the gross/net distinction: net measures account for depreciation. GDP is domestic; GNP adjusts for net factor income from abroad.
