The Evolution of Macro Models at the Federal Reserve Board
Large-scale macroeconomic models have been used at the Federal Reserve Board for nearly thirty years. After briefly reviewing the first generation of Fed models, which were based on the IS/LM/Phillips curve paradigm, the paper describes the structure and properties of a new set of models. The new models are more explicit in their treatment of expectations formation and household and firm intertemporal decisionmaking. The incorporation of more rigorous theoretical microfoundations is accomplished while maintaining a high standard of goodness of fit. Simulations illustrate the effects of ...

Interest rate policies for price stability

What's happened to the Phillips curve?
The simultaneous occurrence in the second half of the 1990s of low and falling price inflation and low unemployment appears to be at odds with the properties of a standard Phillips curve. We find this result in a model in which inflation depends on the unemployment rate, past inflation, and conventional measures of price supply shocks. We show that, in such a model, long lags of past inflation are preferred to short lags, and that with long lags, the NAIRU is estimated precisely but is unstable in the 1990s. Two alternative modifications to the standard Phillips curve restore stability. One ...

The FRB
The FRB/US model of the U.S. economy is one of several that Federal Reserve Board staff consults for forecasting and the analysis of macroeconomic issues, including both monetary and fiscal policy.

Optimal-Control Monetary Policy in the FRB/US Model
The question of how best to conduct monetary policy has been studied by economists for a long time. Over the past 25 years or so, attention has focused on systematic approaches to setting the short-term interest rate in a manner that effectively balances policymaker objectives.

A guide to FRB/US: a macroeconomic model of the United States
FRB/US is a large-scale quarterly econometric model of the U.S. economy, developed to replace the MPS model. Most behavioral equations are based on specifications of optimizing behavior containing explicit expectations of firms, households, and financial markets. Although expectations are explicit, the empirical fits of the structural descriptions of macroeconomic behavior are comparable to those of reduced-form time series models. In most instances, tests do not reject overidentifying restrictions of rational expectations or the hypothesis of serially independent residuals. As modeled, ...

Two practical algorithms for solving rational expectations models
This paper describes the E-Newton and E-QNewton algorithms for solving rational expectations (RE) models. Both algorithms treat a model's RE terms as exogenous variables whose values are iteratively updated until they (hopefully) satisfy the RE requirement. In E-Newton, the updates are based on Newton's method; E-QNewton uses an efficient form of Broyden's quasi-Newton method. The paper shows that the algorithms are reliable, fast enough for practical use on a mid-range PC, and simple enough that their implementation does not require highly specialized software. The evaluation of the ...
