Use the following questions to think about how the government could raise investment without raising output.

a) What would raise investment: higher or lower interest rate

b) Given your answer to (a), what should the Federal Reserve do to the money supply

c) What impact does the Fed’s action in (b) have on output?

d) Explain how a fiscal policy could offset the change to output in (c) without offsetting the change in interest rates in (b).
