Contractionary Policy – Fiscal and Monetary Impact on AD
Macroeconomics
This diagram shows how contractionary fiscal or monetary policy shifts the aggregate demand (AD) curve leftward, reducing inflationary pressure but also decreasing real GDP.
Curves and Elements
ad1
AD1: Initial aggregate demand before contractionary policy.
ad2
AD2: Aggregate demand after contractionary fiscal or monetary policy.
sras
SRAS: Short-run aggregate supply, unchanged in this diagram.
lras
LRAS: Long-run aggregate supply at full employment output.
pl1
PL1: Initial price level before the policy intervention.
pl2
PL2: Lower price level after AD decreases.
y2
Y2: New equilibrium output after demand contraction.
ye
Ye: Full employment level of output.
Contractionary policy is used to reduce inflation by decreasing aggregate demand (AD).
Initially, the economy is in equilibrium at AD1, SRAS, and price level PL1, at the full employment output (Ye).
A shift from AD1 to AD2 reflects the effects of contractionary fiscal policy (e.g., reduced government spending or increased taxes) or contractionary monetary policy (e.g., higher interest rates, reduced money supply).
This leads to a lower equilibrium output (Y2) and a lower price level (PL2), reducing inflationary pressure but potentially increasing unemployment.
The diagram demonstrates how macroeconomic policy can stabilize the economy when aggregate demand is too high.
