The paper examines the optimal combination of central bank independence and conservatism in the presence of uncertain central bank preferences. We develop a model of endogenous monetary policy delegation in which government chooses the central bank's degree of inde-pendence and conservatism so...

This paper revisits the trade-off between central bank independence and conservatism using a New Keynesian model with uncertainty about the central banker's output gap target. It is shown that when this uncertainty is high, the trade-off no longer holds. In this case, the optimal combination...

We examine monetary and fiscal interactions in a monetary union model with uncertainty due to imperfect central bank transparency. It is first shown that monetary uncertainty discourages excessive taxation and may thus reduce average inflation and output distortions. However, as countries enter...

This paper examines the optimal monetary delegation arrangement of central bank independence and conservatism in the presence of uncertainty about the central bank’s output objective. We show that full independence is no longer optimal with uncertain central bank preferences, and that optimal...
