1. Monetary and Fiscal Policy Interact
Unit 5 Lesson 2
Activity 45
By John Morton
Advanced Placement Economics Teacher Resource Manual. National Council on Economic Education, New York, N.Y

2. Objectives
Practice analytical skills with AD and SRAS model and the money market.
Analyze the effects of combined monetary and fiscal policies on the loanable funds market.

3. Introduction
This lesson continues an examination of the interaction between monetary and fiscal policy in the short-run.
It examines the impact of monetary and fiscal policy on output, the price level, unemployment, interest rates and investment.
Your success on the AP Exam depends on your ability to explain why economic variables are affected.

4. Activity 45 provides you with an opportunity to work through the short-run effects of monetary and fiscal policy on important macroeconomic variables.
You will continue to use the loanable funds market and the money market in this activity. (The following slides are not on your activity sheet.)

Suppose that, in response to the economic situation, the federal government decides to increase its spending without increasing taxes and the Fed keeps the money supply constant. There is no Barro-Ricardo effect.
Explain what would happen in the three markets shown above.

6. The AD curve should shift to the right.

The AD curve should shift to the right.
Increase the demand for loanable funds by shifting the curve to the right.
The demand for money should also shift to the right.
The interest rates in the money market and loanable funds should be equal.

Was there crowding-out present in the above graphs?
In the Loanable Funds Market graph, the government’s demand for funds increased the interest rate.

12. Answer the following questions:
What could the Fed have done to prevent crowding-out?
Are there certain conditions when the Fed should or should not prevent crowding-out?
The Fed could use expansionary monetary policy; thus the government’s demand for funds would not result in an increase in interest rates.
If the economy were experiencing a recession, the Fed would want to prevent crowding-out, but if the economy were at or near full employment and government spending increased, the Fed might not want to prevent crowding-out.

13. Graphing Monetary and Fiscal Policy Interactions
Illustrate the short-run effects for each monetary and fiscal policy combination using AD and AS curves, the money market and the loanable funds market.
Once again, assume that there are no changes in the foreign sector.
Circle the appropriate symbols (↑ for increase, ↓ for decrease, and ? for uncertain), and explain the effect of the policies on real GDP, the price level, unemployment, interest rates and investment.

14. The unemployment rate is 10%, and the CPI is increasing at a 2% rate
The unemployment rate is 10%, and the CPI is increasing at a 2% rate. The federal government cuts personal income taxes and increase its spending. The Fed buys bonds on the open market.

(D) Interest Rates: ? Explain
Fiscal policy would result in an increase in interest rates; monetary policy would result in lower interest rates. The net effect depends on the relative strength of the two policies. The graph here shows a slight increase in interest rates; the effect on interest rates is indeterminate.

(D) Interest rates: ? Explain
The Fed decreases the money supply, which should result in an increase in interest rates. The increase in taxes and decrease in government spending result in a decrease in interest rates since the demand for loanable funds by the government should decrease. The demand for money decrease because of the decrease I real GDP. Interest rates will be higher if the decrease in demand is less than the decrease in supply in the money market. The interest rate effect is indeterminate.
