This paper assumes that a central bank commits itself to maintaining an inflation target and then asks what measure of the inflation rate the central bank should use if it wants to maximize economic stability. The paper first formalizes this problem and examines its microeconomic foundations. It...

Analysis of quantitative easing (QE) typically focus on the recent past studying the policy's effectiveness during a financial crisis when nominal interest rates are zero. This paper examines instead the usefulness of QE in a future fiscal crisis, modeled as a situation where the fiscal outlook...

What set of institutions can support the activity of a central bank? Designing a central bank requires specifying its objective function, including the bank's mandate at different horizons and the choice of banker(s), specifying the resource constraint that limits the resources that the central...

This paper surveys the research in the past decade on imperfect information models of aggregate supply and the Phillips curve. This new work has emphasized that information is dispersed and disseminates slowly across a population of agents who strategically interact in their use of information....

This paper reviews the unconventional U.S. monetary policy responses to the financial and real crises of 2007-09, divided into three groups: interest rate policy, quantitative policy, and credit policy. To interpret interest rate policy, it compares the Federal Reserve's actions with the...

This paper develops and analyzes a general-equilibrium model with sticky information. The only rigidity in goods, labor, and financial markets is that agents are inattentive, sporadically updating their information sets, when setting prices, wages, and consumption. After presenting the...

We examine to what extent variants of inflation-forecast targeting can avoid stabilization bias, incorporate history-dependence, and achieve determinancy of equilibrium, so as to reproduce a socially optimal equilibrium. We also evaluate these variants in terms of the transparency of the...

This paper is a contribution to the analysis of optimal monetary policy. It begins with a critical assessment of the existing literature, arguing that most work is based on implausible models of inflation-output dynamics. It then suggests that this problem may be solved with some recent...

Monetary policy can achieve average inflation equal to a given inflation target and, at best, a good compromise between inflation variability and output-gap variability. Monetary policy cannot completely stabilize either inflation or the output gap. Increased credibility in the form of inflation...

It is argued that inflation targeting is best understood as a commitment to a targeting rule rather than an instrument rule, either a general targeting rule (explicit objectives for monetary policy) or a specific targeting rule (a criterion for (the forecasts of) the target variables to be...
