Inflationary expenditure gap or recessionary expenditure gap

Question

Refer to the table below in answering the questions which follow:

In this economy if full employment is 130 million, will there be an inflationary expenditure gap or recessionary expenditure gap? Describe the consequence of this gap? By how much would aggregate expenditures in column 3 ought to change at each level of GDP to remove the inflationary expenditure gap or recessionary expenditure gap? Illustrates. Describe multiplier in this example?

Answer 1

A recessionary gap. Equilibrium GDP is $600 billion, whereas full employment GDP is $700 billion. Employment = 20 million less than at full employment. Aggregate expenditures would have to rise by $20 billion (= $700 billion -$680 billion) at each level of GDP to abolish the recessionary gap. The MPC is .8, thus the multiplier is 5.
