The amount by which the equilibrium level of real GDP exceeds the full employment level of GDP is called
- A.recessionary gap
- B.inflationary gap
- C.income multiplier
- D.automatic stabilizer
Show answer
Correct answer: B. inflationary gap
Explanation
The correct answer is B, inflationary gap. When demand pushes the economy to produce more than it can at full employment, the extra demand only drives prices up. Full-employment GDP, also called potential GDP, is the output an economy can produce when all its resources are in use. If aggregate demand is so high that equilibrium real GDP sits above this level, the difference is the inflationary gap. Real output cannot keep rising beyond capacity, so the excess shows up as rising prices. The idea comes from J.M. Keynes, who used it in his 1940 pamphlet "How to Pay for the War", and the cure is to cut demand through higher taxes, lower government spending or tighter money. Option A is wrong because a recessionary gap is the opposite case, when equilibrium GDP falls short of full employment. Option C is wrong because the income multiplier measures how much income rises for each rupee of new spending. Option D is wrong because automatic stabilisers are tools, such as progressive taxes, that help narrow these gaps. Exam tip: output above potential is an inflationary gap; output below potential is a recessionary gap.
