Concept:Restrictive monetary policy is a contractionary policy used to reduce aggregate demand and close an inflationary gap.
Explanation:When total demand for goods and services exceeds what the economy can produce at full employment, an inflationary gap occurs.
This excess spending pushes prices upward.
Restrictive monetary policy is designed to curtail aggregate demand so that total spending falls back to a sustainable level.
Central banks implement this by raising interest rates, which increases the cost of borrowing.
Consequently, firms reduce investment and households cut back on consumption, lowering aggregate demand.
As aggregate demand falls, pressure on prices decreases and the inflationary gap shrinks.
Therefore, this policy is applied to overcome an inflationary gap, not deflation or disinflation.
Answer:D. Inflationary gap.
