Key Concepts

Tax Multiplier

The tax multiplier measures how changes in taxation affect total economic output. Typically, an increase in taxes reduces disposable income and consumption, thereby decreasing aggregate demand. Its impact on overall output is usually smaller in absolute terms compared to the government expenditure multiplier and reflects the marginal propensity to consume within the economy.

Balanced Budget Multiplier

This concept arises when the government simultaneously increases spending and taxes by the same amount. Under certain theoretical conditions, even though the fiscal adjustment is balanced, the net effect on output is positive. The balanced budget multiplier, sometimes observed to be equal to one, demonstrates that the direct impact of increased government spending outweighs the contractionary effect from higher taxes, resulting in an overall rise in aggregate demand.

Government Expenditure Multiplier

This concept refers to the ratio indicating how much total economic output increases in response to an incremental rise in government spending. It accounts for the initial boost in spending and the subsequent rounds of income and re-spending throughout the economy. The multiplier is central to fiscal policy analysis as it helps determine the overall impact of government expenditure on economic activity.
