Wrap-Up

DIFFERENCES BETWEEN MONETARY AND

FISCAL POLICY

Effects on Aggregate Demand

Fiscal policy and monetary policy have different effects on the economy. Expansionary

fiscal policy raises the real interest rate and crowds out private investment spending.

Expansionary monetary policy lowers the real interest rate and stimulates

private investment spending.

Policy Lags

Inside lag: The time required to recognize a need for a change in policy and to

implement the policy change. The inside lag is much shorter for monetary policy.

Outside lag: The time required for the change in policy to affect the economy. The

outside lag is normally shorter for fiscal policy.
