Correct Option
The correct option is 1 and 3 only.
Explanation
In macroeconomics, the impact of fiscal policy on equilibrium income is measured by the multiplier effect. This concept quantifies how a change in autonomous spending (such as government expenditure or transfers) affects the overall output or income level in the economy. The magnitude of the multiplier depends on the Marginal Propensity to Consume (MPC).
Statement-wise Analysis
- Statement 1 is Correct: Government expenditure ($G$) is a direct component of Aggregate Demand ($AD$). When the government spends money, it directly purchases goods and services, injecting the full amount into the economy immediately. In contrast, Government Transfers ($Tr$) (e.g., unemployment benefits, subsidies) first increase households' disposable income. Households then choose to spend a portion and save a portion. Because some of the transfer leaks out as savings immediately, the initial increase in aggregate demand is smaller than the transfer amount. Therefore, $G$ has a larger impact on equilibrium income.
- Statement 2 is Incorrect: Transfers are not fully spent. The consumption from transfers depends on the Marginal Propensity to Consume (MPC). Households spend only a fraction ($c$) of the transfer and save the rest ($1-c$). Since $MPC$ is typically less than 1, the initial injection into the economy is less than the total transfer amount.
- Statement 3 is Correct: The formulas for the multipliers mathematically demonstrate the difference in impact:
- The Government Expenditure Multiplier is $\frac{1}{1 - MPC}$.
- The Transfer Multiplier is $\frac{MPC}{1 - MPC}$.
Key Takeaway
Government Expenditure impacts the economy more than Transfers because expenditure is a direct injection into aggregate demand, whereas transfers are subject to "leakage" through savings before they contribute to spending.
