Abstract

In this paper we analyse the equilibrium degree of commitment in monetary policy to an independent central banker whose preferences are imperfectly observed by private agents. We characterize the incentive compatible strategies by a central bank in office for two periods with no restrictions on its type space. The equilibrium level of commitment is also characterized. We show that when incentive compatibility constraints are binding for a non trivial subset of types of central banks the equilibrium level of commitment involves bunching: different types of rational governments commit monetary policy to similar institutions.
