Suppose that the Fed suddenly and unexpectedly decreases the money supply in an effort to reduce inflation. As a result of this unanticipated
action, actual inflation falls to 3%.
On the previous graph, use the black point (plus symbol) to illustrate the short-run effects of this policy.
Now, suppose that-after a period of 3% inflation-households and firms begin to expect that the inflation rate will continue to be 3%.
On the previous graph, use the purple line (diamond symbol) to draw SRPC₂, the short-run Phillips curve that is consistent with these
expectations, assuming that it is parallel to SRPC₁. Finally, use the orange point (square symbol) to indicate the new, long-run equilibrium for
this economy.

O No, because the Fed cannot affect the inflation rate through monetary policy.

O Yes, but only in the short run; in the long run, inflation returned to its natural rate.
Now, suppose that the public fully anticipates the Fed's decision to decrease the money supply. Assume the public also believes that the Fed is
firmly committed to carrying out this policy. According to rational expectations theory, when the economy is in long-run equilibrium, a fully
