What is the welfare loss arising from uncertainty about true policy targets? We quantify these effects in a DSGE model where private agents are unable to distinguish between temporary shocks to potential output and to the inflation target. Agents use optimal filtering techniques to construct...

This paper argues that incorporating information about the financial cycle is important to improve measures of potential output and output gaps. Conceptually, identifying potential output with non-inflationary output is too restrictive. Potential output is seen as sustainable; yet experience...
