Answer: Expenditures multiplier = 4
Explanation:
Given that,
Potential output = $1000
Price level associated with full-employment output = $100
Current level of output = $1,100 at price level = $100
Current aggregate demand = $1,200
Required shift in the aggregate demand = $200
If government restores economy back to its initial position of full employment by reducing government purchases by $50, then
Expenditures multiplier = \frac{Required\ shift\ in\ aggregate\ demand}{Change\ in\ government\ purchases}
= [tex]\frac{200}{50}[/tex]
= 4
