a) aggregate expenditure is less than the real output here, Hence there exists recessionary expenditure gap exists.
Aggregate expenditure would have to increase by equal to $ 20 Billion.
Multiplier value = Change in GDP/Change in Expenditure
= 50/40
= 1.25
b) Aggregate expenditure is greater than the Real output or GDP. Inflationary expenditure Gap exists here.
Inflationary expenditure gap is $ 20 Billion.
c)
MPC = 40/50
= 0.8
MPS = 1 -0.8
= .02
multiplier = 1/MPS
= 1/0.2
= 5
