A number of interest rate reaction functions and instrument rules have been proposed to implement or approxmiate commitment policy. We assess these optimal reaction functions and instrument rules in terms of whether they lead to an RE equilibrium that is both locally determinate and stable under adaptive learning by private agents. A reaction function that appropriately depends explicitly on private expectations performs well on both counts.568320 bytesapplication/pdfen-USDeterminacyStabilityAdaptive learningInterest rate settingCommitmentMicroeconomicsMacroeconomicsMonetary policy (Targets, instruments, and effects)Working Paper
