Inflation inertia and optimal delegation of monetary policy

Abstract

This paper analyzes the relationship between the optimal weight on output gap in the central bank's loss function and the degree of inertia in a hybrid version of New Keynesian model with a pure discretionary inflation targeting. I show that under endogenous persistence of inflation dynamics, even in discretionary monetary policy regime, a Rogoff's (1985) conservative central banker does not necessarily improve social welfare.
