Inflation Inertia and Optimal Delegation of Monetary Policy

  • Keiichi Morimoto


    (Graduate School of Economics, Osaka University)

Registered author(s):

    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.
