With rare exception, studies of monetary policy tend to neglect the timing of the innovations to the monetary policy instrument. Models which do take timing seriously are often difficult to compare to standard VAR models of monetary policy because of the differences in the frequency that they...

The nature of the business cycle appears to have changed. Prior to the 1990s, recoveries from recessions were quick and steep; after the past three recessions, however, recoveries were weak and prolonged. We consider the effect of a number of countercyclical policies intended to shorten...

Factor models have become useful tools for studying international business cycles. Block factor models [e.g., Kose, Otrok, and Whiteman (2003)] can be especially useful as the zero restrictions on the loadings of some factors may provide some economic interpretation of the factors. These models,...

In the wake of the Great Recession, the Federal Reserve lowered the federal funds rate target essentially to zero and resorted to unconventional monetary policy. With the nominal FFR constrained by the zero lower bound (ZLB) for an extended period, empirical monetary models cannot be estimated...

Previous studies have documented disparities in the regional responses to monetary policy shocks; this variation has been found to depend, in part, on differences in the industrial composition of the regional economies. However, because of computational issues, the literature has often neglected...

In a recent paper, Galí, López-Salido, and Vallés (2003) examined the Federal Reserve’s response to VAR-identified technology shocks. They found that during the Martin-Burns- Miller era, the Fed responded to technology shocks by overstabilizing output, while in the Volcker-Greenspan era,...

We survey the recent empirical literature using long run restrictions to identify technology shocks. We provide an illustrative walkthrough of the long-run restricted vector autoregression (VAR) methodology in a bivariate framework. Additionally, we offer an alternative identification of...

Recent studies using long-run restrictions question the validity of the technology-driven real business cycle hypothesis. We propose an alternative identi cation that maximizes the contribution of technology shocks to the forecast-error variance of labor productivity at a long, but finite,...

Monetary policy VARs typically presume stability of the long-run outcomes. We introduce the possibility of switches in the long-run equilibrium in a cointegrated VAR by allowing both the covariance matrix and weighting matrix in the error-correction term to switch. We find that monetary policy...
