Splitting GDP using National Spending and Factor Income Approaches in Macroeconomics

Gross Domestic Product (GDP) is decomposed analytically via the National Spending Approach and the Factor Income Approach to identify exogenous shocks within macroeconomic aggregates. The former defines GDP as the sum of consumption, investment, government purchases, and net exports, while the latter equates it to Gross Domestic Income comprising employee compensation, rent, interest, and profits under the assumption that production value equals factor income distribution. This dual accounting framework enables economists to differentiate between demand-side fluctuations in specific sectors versus supply-side changes in national income generation within a market economy.
