This paper examines the optimal response of monetary and fiscal policy to a decline in aggregate demand. The theoretical framework is a two-period general equilibrium model in which prices are sticky in the short run and flexible in the long run. Policy is evaluated by how well it raises the...

This paper addresses the issue of how to give optimal advice about monetary policy when it is known that the advice may not be heeded. We examine a simple macroeconomic model in which monetary policy has the ability to stabilize output by offsetting exogenous shocks to aggregate demand. 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...

This essay discusses the role of Milton Friedman's presidential address to the American Economic Association, which was given a half century ago and helped set the stage for modern macroeconomics. We discuss where macroeconomics was before the address, what insights Friedman offered, where...

This paper explores a model of wage adjustment based on the assumption that information disseminates slowly throughout the population of wage setters. This informational frictional yields interesting and plausible dynamics for employment and inflation in response to exogenous movements in...

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...

This paper addresses the issue of how to give optimal advice about monetary policy when it is known that the advice may not be heeded. We examine a simple macroeconomic model in which monetary policy has the ability to stabilize output by offsetting exogenous shocks to aggregate demand. The...

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...

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 discusses the conduct and performance of U.S. monetary policy during the 1990s, comparing it to policy during the previous several decades. It reaches four broad conclusions. First, the macroeconomic performance of the 1990s was exceptional, especially if judged by the volatility of...
