Use the money demand and money supply model to show graphically and briefly explain
the effect on interest rates if real GDP increases.
Table 16–2
Year Potential Real GDP Real GDP Price Level
2010 $13.5 trillion $13.5 trillion 142
2015 $14.0 trillion $14.4 trillion 150
Refer to Table 16–2. The hypothetical information in the table shows what the values for
real GDP and the price level will be in 2011 if the Federal Reserve does not use monetary
policy:
a. If the Fed wants to keep real GDP at its potential level in 2011, should it use an
expansionary policy or a contractionary policy? Should the trading desk buy T–bills or
sell them?
b. Suppose the Fed’s policy is successful in keeping real GDP at its potential level in 2011.
State whether each of the following will be higher or lower than if the Fed had taken no
action:
(i) Real GDP
(ii) Full–employment real GDP
(iii) The inflation rate
(iv) The unemployment rate
c. Draw an aggregate demand and aggregate supply graph to illustrate your answer. Be
sure that your graph contains LRAS curves for 2010 and 2011; SRAS curves 2010 and
2011; AD curve for 2010 and 2011, with and without monetary policy actions; and
equilibrium real GDP and the price level in 2011 with and without policy.
