This paper outlines important lessons for monetary policy. In particular, the role of inflation targeting, which was much acclaimed prior to the financial crisis and since then has not lost much of its endorsement, is critically reviewed. Ignoring the relation between monetary policy and asset...

Central bank communication plays an important role in shaping market participants' expectations. This paper studies a simple nonlinear model of monetary policy in which agents have incomplete information about the economic environment. It shows that agents' learning and the dynamics of the...

Central banks often make announcements even though, in models in which dynamic time inconsistency of optimal policy plays a role, they have an incentive to lie. This paper studies the way inflation targeting affects the incentives the central bank faces in announcing its target inflation rate...

This paper explores the effects of central bank transparency on the performance of optimal inflation targeting rules. I assume that both the central bank and the private sector face uncertainty about the correct model of the economy and have to learn. A transparent central bank can reduce one...

In a standard New Keynesian model, a myopic central bank concerned with stabilizing inflation and changes in the output gap will implement a policy under discretion that replicates the optimal, timeless perspective, precommitment policy. By stabilizing output gap changes, the central bank...

In this paper, I revisit an old question in the analysis of monetary policy that was first studied by Rogoff (1985) - should central banks pursue objectives that differ systematically from social welfare? I investigate how the answer to this question is affected by the degree of transparency...

Central bank communication plays an important role in shaping market participants’ expectations. This paper studies a simple nonlinear model of monetary policy in which agents have incomplete information about the economic environment. It shows that agents’ learning and the dynamics of the...

Ordinary Least Squares (OLS) estimation of monetary policy rules produces potentially inconsistent estimates of policy parameters. The reason is that central banks react to variables, such as in ation and the output gap, which are endogenous to monetary policy shocks. Endogeneity implies a...
