Question:

For an economy starting at potential output, a decrease in autonomous expenditure in the short-run results in a(n):

A. increase in potential output

B. recessionary output gap

C. decrease in potential output

D.  expansionary output gap

The correct answer is B

Explanation:

A decrease in autonomous expenditure shifts the Planned Aggregate Expenditure curve downward thus creating a lower equilibrium output.

PAE = C + Ip + G + NX

where

PAE  = Planned Aggregate Expenditure

C = consumption

Ip = Investment Spending

G = Government Spending

NX =  Net Export

If an economy has its output equal to its potential, this will create a reduction in short-run equilibrium output leading to a recessionary output gap.
