Suppose that the central bank for this economy suddenly and unexpectedly decreases the money supply in an effort to reduce inflation. As a result of
this unanticipated policy action, actual inflation falls to 3%.
On the previous graph, use the black point (plus symbol labeled "B") to illustrate the short-run effects of this policy.
Suppose that now, after a period of 3% inflation, households and firms begin to expect that the inflation rate will persist at the level of 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 SRPC₂-
Finally, using the orange point (square symbol labeled "C"), indicate on the previous graph the new, long-run equilibrium for this economy.
The inflation rate at point C is
unemployment rate at point A.
the inflation rate at point A, and the unemployment rate at point C is
Was the central bank able to achieve its goal of lowering inflation?
O Yes, the central bank's policy successfully reduced inflation in both the short run and the long run.
O Yes, but only in the short run; in the long run, inflation returned to its natural rate.
O No, because the central bank cannot affect the inflation rate through monetary policy.
the
Now, suppose that the public fully anticipates the central bank's decision to decrease the money supply. Assume the public also believes that the
monetary authority is firmly committed to carrying out this policy. According to rational expectations theory, when the economy is in long-run
equilibrium, a fully anticipated decrease in the money supply will cause the economy to move
previous Phillips curve graph. In this case, rational expectations theory predicts that the fully anticipated decrease in the money supply will have the
immediate effect of
in the inflation rate and
in the unemployment rate.
