Economic outcomes in dynamic economies with forward-looking agents depend crucially on whether or not the central bank can precommit, even in the absence of the traditional "inflation bias." This paper quantifies the welfare differential between precommitment and discretionary policy in both a...

This paper solves for optimal policy rules in a stylized small open economy model under a spectrum of targeting regimes. These policy reaction functions are presented as feedback rules highlighting the dominant state variables in each rule. Optimal simple rules - rules that exploit a reduced...

This paper stresses that estimated policy rules are reduced form equations that are silent on many important policy questions. To obtain a structural understanding of monetary policy it is necessary to estimate the policymaker's objective function, rather than its policy reaction function. With...

Ball (1997) shows using a small closed economy model that nominal GDP targeting can lead to instability. This paper extends Ball's model to uncover the role inflation expectations play in generating this instability. By changing the process by which inflation expectations are formed in the...

Many central banks conduct monetary policy according to an inflation-targeting framework. Central to such a framework is the principle that monetary policy decisions are formulated in the context of an explicitly announced numerical target or range for some measure of inflation. Obviously, if an...

This Economic Letter looks at time-inconsistency, describing why the same mechanisms that can lead to higher average inflation also can hamper policymakers' efforts to keep inflation stable.

This Economic Letter looks at the problems with the NKPC and discusses some alternatives that are increasingly being used to think about inflation and the monetary policy transmission mechanism.

Inflation targeting has been adopted by many central banks, but not by the U.S. Federal Reserve. Using an estimated New Keynesian business cycle model, I perform counterfactual simulations to consider how history might have unfolded if the Federal Reserve had adopted a form of flexible inflation...
