Abstract

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