In a stylized DSGE model with an energy sector, the optimal policy response to an adverse energy supply shock implies a rise in core inflation, a larger rise in headline inflation, and a decline in wage inflation. The optimal policy is well-approximated by policies that stabilize the output gap,...

This paper explores issues that arise in implementing monetary policy under conditions of sustained price stability. We discuss several issues that concern the selection of a central bank's inflation objective under such conditions: price measurement; the behavior of other key variables,...

We describe the inflation targeting framework (ITF) and compare it against hypothetical best-practice based on optimization. The core requirements of the ITF are an explicit long-run inflation goal and a commitment to transparency in policymaking. Advocates and practitioners of the ITF have made...

A growing body of evidence suggests that ongoing relationships between consumers and firms may be important for understanding price dynamics. We investigate whether the existence of such customer relationships has important consequences for the conduct of both long-run and short-run policy. Our...

The volatility of U.S. real GDP growth since 1984 has been markedly lower than that over the previous quarter-century. In this paper, we utilize frequency-domain and VAR methods to distinguish among several competing explanations for this phenomenon: improvements in monetary policy, better...

The Barro-Gordon inflation bias has provided the most influential argument for fixed exchange rate regimes. However, with low inflation rates now widespread, credibility concerns seem no longer relevant. Why give up independent monetary policy to contain an inflation bias that is already under...

Inflation in the U.S. rose in the 1970s and fell in the 1980s and 1990s. The conventional story attributes this pattern to changes in monetary policy. Policymakers made errors and learned from them. This article presents the story and existing alternatives that emphasize instead changes beyond...

This article characterizes the change in the nature of the money growth-inflation and unemployment-inflation relationships between the first and second halves of the twentieth century. The changes are substantial, and the authors discuss some of the implications for modeling inflation dynamics,...

Since the early 1990s, a number of central banks have adopted numerical inflation targets as a guide for monetary policy. The targets are intended to help central banks achieve and maintain price stability by specifying an explicit goal for monetary policy based on a given time path for a...
