Inflation Inertia and Optimal Delegation of Monetary Policy

This paper analyzes the relationship between the optimal weight on output gap in the central bankfs 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 Rogofffs (1985) conservative central banker does not necessarily improve social welfare.
