This paper examines a model of dynamic price adjustment based on the assumption that information disseminates slowly throughout the population. Compared to the commonly used sticky-price model, this sticky-information model displays three related properties that are more consistent with accepted...

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...

The dynamic stochastic general equilibrium (DSGE) models used to study business cycles typically assume that exogenous disturbances are independent first-order autoregressions. This paper relaxes this tight and arbitrary restriction by allowing for disturbances that have a rich contemporaneous...

This paper presents a dynamic stochastic general-equilibrium model with a single friction in all markets: sticky information. In this economy, agents are inattentive because of the high cost of acquiring, absorbing and processing information, so that the actions of consumers, workers and firms...

Alan Greenspan was sworn in as Chairman of the Board of Governors of the Federal Reserve System almost exactly 18 years ago. At the time, the Reagan administration was being rocked by the Iran-contra scandal. The Berlin Wall was standing tall while, in the Soviet Union, Mikhail Gorbachev had...

This paper estimates a common component in many price series that has an equiproportional effect on all prices. Changes in this component can be interpreted as changes in the value of the numeraire since, by definition, they leave all relative prices unchanged. The first aim of the paper is to...
