This paper develops and estimates a macro-finance model that combines a canonical affine no-arbitrage finance specification of the term structure with standard macroeconomic aggregate relationships for output and inflation. From this new empirical formulation, we obtain several important...

Central banks pay close attention to inflation expectations. In standard models, however, inflation expectations are tied down by the assumption of rational expectations and should be of little independent interest to policy makers. In this paper, we relax the assumption of rational expectations...

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...

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...

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...

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,...

This paper stresses that estimated policy rules are reduced form equations that are silent on many important policy questions. To obtain a structural understanding of monetary policy it is necessary to estimate the policymaker's objective function, rather than its policy reaction function. With...

This paper considers the monetary policymaker’s joint problem of model estimation and the design of a policy rule in the face of uncertainty regarding the process of structural change in the economy. Unobserved structural change is modeled through time variation in the natural rates of...

This paper estimates two optimization-based sticky-price New Keynesian models and assesses how well they describe U.S. output, inflation, and interest rate dynamics. We consider models in which either internal habit formation influence consumption behavior, and in which Calvo-pricing and...
