Balanced Budget Multiplier
balanced budget multipliera change in AGGREGATE DEMAND brought about by a change in GOVERNMENT EXPENDITURE, which is exactly matched by a change in revenues received from TAXATION and other sources. The change in government expenditure has an immediate effect on aggregate demand and generates income of an equivalent size. By contrast, the change in taxation does not change aggregate demand by an equivalent amount because some of the increased/reduced DISPOSABLE INCOME will be offset by changes in SAVING.
Consequently, an increase in government expenditure and taxation of equal amounts will have a net expansionary effect on aggregate demand and incomes, while a decrease in government expenditure and taxation of equal amounts will have a net contractionary effect. See BUDGET, FISCAL POLICY.
