Estimated monetary policy rules often appear to indicate a sluggish partial adjustment of the policy interest rate by the central bank. In fact, such evidence does not appear to be persuasive, since the illusion of monetary policy inertia may reflect spuriously omitted persistent influences on...

Economic outcomes in dynamic economies with forward-looking agents depend crucially on whether or not the central bank can precommit, even in the absence of the traditional "inflation bias." This paper quantifies the welfare differential between precommitment and discretionary policy in both a...

This paper studies robust control problems when policy is set with commitment. One contribution of the paper is to articulate an approximating equilibrium that differs importantly from that developed in Hansen and Sargent (2003). The paper illustrates how the proposed approximating equilibrium...

Nominal income rules for monetary policy have long been debated, but two issues are of particular recent interest. First, there are questions about the performance of such rules over a range of plausible empirical models-especially models with and without rational inflation expectations. Second,...

The literature on robust monetary policy rules has largely focused on the case in which the policymaker has a single reference model while the true economy lies within a specified neighborhood of the reference model. In this paper, we show that such rules may perform very poorly in the more...

This paper uses a small data-consistent model of the United States to identify and estimate the Federal Reserve's policy preferences. We find critical differences between the policy regimes in operation during the Burns-Miller and Volcker-Greenspan periods. Over the Volcker-Greenspan period we...

We examine the performance and robustness of monetary policy rules when the central bank and the public have imperfect knowledge of the economy and continuously update their estimates of model parameters. We find that versions of the Taylor rule calibrated to perform well under rational...

Using a short-term interest rate as the monetary policy instrument can be problematic near its zero bound constraint. An alternative strategy is to use a long-term interest rate as the policy instrument. We find when Taylor-type policy rules are used to set the long rate in a standard New...

We examine the performance and robustness properties of alternative monetary policy rules in the presence of structural change that renders the natural rates of interest and unemployment uncertain. Using a forward-looking quarterly model of the U.S. economy, estimated over the 1969-2002 period,...

Woodford (1999) develops the notion of a "timelessly optimal" pre-commitment policy. This paper uses a simple business cycle model to illustrate this notion. We show that timelessly optimal policies are not unique and that they are not necessarily better than the time-consistent solution....
