Contractionary Policy – Fiscal and Monetary Impact on ADSL
MacroeconomicsThis 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.
Key explanations
- 1
Contractionary policy is used to reduce inflation by decreasing aggregate demand (AD).
- 2
Initially, the economy is in equilibrium at AD1, SRAS, and price level PL1, at the full employment output (Ye).
- 3
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).
- 4
This leads to a lower equilibrium output (Y2) and a lower price level (PL2), reducing inflationary pressure but potentially increasing unemployment.
- 5
The diagram demonstrates how macroeconomic policy can stabilize the economy when aggregate demand is too high.
Example exam question
Using an AD/AS diagram, explain how contractionary fiscal and monetary policy can reduce inflation in an economy.
Show example answer
In the AD/AS diagram, contractionary policy causes a leftward shift in the aggregate demand curve from AD1 to AD2. This shift can result from fiscal tightening (higher taxes or lower government spending) or monetary tightening (higher interest rates). The result is a lower price level (PL2) and reduced output (Y2), helping to combat inflation.
