a. To achieve an increase in the interest rate target, would the Federal Reserve increase or decrease the nominal money supply?

b. Using the AD-AS model, show graphically how the change in the money supply described in part (a) would affect prices and output over the short- and longrun. What would happen to real interest rates in the long run?

c. Are your findings in part (b) consistent with what actually occurred in the early 1980s?
