Previous models of rules versus discretion are extended to include uncertainty about the policymaker's "type." When people observe low inflation, they raise the possibility that the policymaker is committed to low inflation (type 1). This enhancement of reputation gives the uncommitted policymaker (type 2) an incentive to masquerade as the committed type. In the equilibrium the policymaker of type 1 delivers surprisingly low inflation -- with corresponding costs to the economy -- over an extended interval. The type 2 person mimics this outcome for awhile, but shift seventually to high inflation. This high inflation is surprising initially, but subsequently becomes anticipated.
