An optimal control tool is described that is particularly useful for computing rules of large-scale models where users might otherwise have difficulty determining the state vector a priori and where the inversion of large, sparse matrices is involved. A small-scale demonstration is presented, as...

The costs of disinflation are explored using the Board's new sticky-price rational expectations macroeconometric model of the U.S. economy, FRB/US. The model nests both model consistent and `restricted-information rational' expectations. Monetary policy is governed by interest-rate reaction...

We examine learning, model misspecification, and robust policy responses to misspecification in a quasi-real-time environment. The laboratory for the analysis is the Sargent (1999) explanation for the origins of inflation in the 1970's and the subsequent disinflation. Three robust policy rules...

In the 2-1/2 years between March, 1996 and September, 1998 the civilian unemployment rate in the United States dropped a full percentage point, the 12-month CPI inflation rate fell nearly 1-1/2 percentage points, a major crisis developed in emerging economies, and commodity prices collapsed....

This paper explores Knightian model uncertainty about dynamic misspecification as a possible explanation of the considerable difference between estimated interest rate rules and optimal feedback descriptions of monetary policy. In the literature on robust control, Knightian uncertainty about a...

We exploit data on historical revisions to real-time estimates of the output gap to examine the implications of measurement error for the design of monetary policy, using the Federal Reserve's model of the U.S. economy, FRB/US. Measurement error brings about a substantial deterioration in...

In recent years, the learnability of rational expectations equilibria (REE) and determinacy of economic structures have rightfully joined the usual performance criteria among the sought-after goals of policy design. Some contributions to the literature, including Bullard and Mitra (2001) and...

The monetary policy rules that are widely discussed--notably the Taylor rule--are remarkable for their simplicity. One reason for the apparent preference for simple ad hoc rules over optimal rules might be the assumption of full information maintained in the computation of an optimal rule....
