18. The time inconsistency of monetary policy means that
a. once people have formed expectations of low inflation based on a promise by the central bank,

b. at some times central banks think it is more important to keep unemployment low; at other
times, they think it is more important to keep inflation low.
c. monetary policy is not consistent across time because it is influenced by politics.
d. monetary policy is not consistent across time because policymakers are incompetent.
19. Time inconsistency will cause the
a. short-run Phillips curve to be higher than otherwise.
b. short-run Phillips curve to be lower the otherwise.
c. long-run Phillips curve to be farther to the right than otherwise.
d. long-run Phillips curve to be farther left than otherwise.
20. If a government managed to reduce the time inconsistency problem by mandating that the central
bank target inflation at a low rate, then
a. the long–run Phillips curve would shift right.
b. the long–run Phillips curve would shift left.
