This paper studies how a central bank's preference for robustness against model misspecification affects the design of monetary policy in a New-Keynesian model of a small open economy.Due to the simple model structure, we are able to solve analytically for the optimal robust policy rule, and we...

Inflation targeting involves using all available information in stabilizing inflation around some target rate (Svensson, 2003). Inflation is typically at the very end of the transmission mechanism and hence its determination is subject to much model uncertainty which the central bank will want...

Monetary policy transmission lags create credibility problems for the inflationtargeting policy maker who acts under discretion. We show that if prices react to monetary policy with a longer lag than output, the welfare maximizing inflationtargeting policy implies no policy stabilization of...

We study the effects of model uncertainty in a simple New Keynesian model using robustcontrol techniques. Due to the simple model structure, we are able to find closed-formsolutions for the robust control problem, analyzing both instrument rules and targetingrules under different timing...
