What rule should a central bank interested in inflation stability follow? Because monetary policy tends to work with lags, it is tempting to use inflation forecasts to generate policy advice. This article, however, suggests that the use of forecasts to drive policy is potentially destabilizing....

There is growing evidence that the empirical Phillips curve within the US has changed significantly since the early 1980’s. In particular, inflation persistence has declined sharply. The paper demonstrates that this decline is consistent with a standard Dynamic New Keynesian (DNK) model in...

We trace the consequences of an energy shock on the economy under two different monetary policy rules: a standard Taylor rule where the Fed responds to inflation and the output gap; and a Taylor rule with inertia where the Fed moves slowly to the rate predicted by the standard rule. We show that...

The Taylor rule, which once was mentioned only in scholarly economics journals, now is popping up regularly in newsmagazines, finance journals, and central bankers' speeches. Does the Fed follow the rule? Should it? This Commentary explains what the Taylor rule is, discusses why it seems to...

Monetary policymakers look to the Phillips curve—an expression of the relationship between inflation and the degree to which the economy is operating relative to its potential—for information about the cost of actions undertaken to lower inflation. Recent estimations of the curve suggest it...

Monetary policy rules help central banks exercise the discipline necessary to achieve their long-term goals. The type of rule many banks are turning to these days is inflation targeting, which has several advantages. But because banks base their actions on forecasts of future inflation,...

Low inflation over long periods is the sign of an effective central bank. The authors suggest that a large fraction of the worldwide decline in inflation since the early 1980s results from an international movement toward more independent central banks.

Observations that the Phillips curve may be deviating from historical norms are important to policymakers because deviations would imply that more or less output has to be sacrificed to achieve a permanent reduction in long-term inflation. But we argue that recent economic shocks and a shift in...

Is inflation (in the often-quoted words of Milton Friedman) "always and everywhere a monetary phenomenon"? Some say no, arguing that inflation is controlled not only by the central bank but also by the fiscal authority. This Commentary authors explore their argument, known as the fiscal theory...

What inflation rate should the central bank target? The authors address determinacy issues related to this question in a two-sector model in which prices can differ in equilibrium. They assume that the degree of nominal price stickiness can vary across sectors and that labor is immobile. This...
