The multiplier indicates the extent of the change in __________ following a variation in ____________?
Show answer Hide answer
Answer: D. output aggregate demand
Explanation
The multiplier measures how aggregate output changes following aggregate demand shifts. Initial spending injections trigger secondary rounds of consumer expenditure throughout the economy. Total GDP changes by a magnified amount compared to the initial demand shock. Keynesian macroeconomics utilizes multipliers to quantify fiscal policy effectiveness. Marginal propensities to consume determine the exact mathematical size of the multiplier. Leakages like savings and taxes reduce the overall power of the expenditure multiplier.
Governments apply multiplier estimates when planning infrastructure stimulus spending. Economic downturns prompt increased public spending to counteract falling private demand. Accurate multiplier calculation helps prevent overstimulating an economy into inflation. Consumption and income describe behavioral relationships rather than multiplier output effects. Investment and output capture partial components rather than broad aggregate demand. Savings and investment represent financial flows rather than total output responses.
