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 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 paper proposes a theory of supply shocks, or shifts in the short-run Phillips curve, based on relative-price changes and frictions in nominal price adjustment. When price adjustment is costly, firms adjust to large shocks but not to small shocks, and so large shocks have disproportionate...

Fluctuations in real GNP have traditionally been viewed as transitory deviations from a deterministic time trend. The purpose of this paper is to review some of the recent developments that have led to a new view of output fluctuations and then to provide some additional evidence. Using post-war...

This paper examines an economy in which aggregate shocks are not dispersed equally throughout the population. Instead, while these shocks affect all individuals ex ante, they are concentrated among a few ex post.The equity premium in general depends on the concentration of these aggregate...

In this paper, we re-examine the standard analysis of the short-run effect of a personal tax cut. If consumer spending generates more money demand than other components of GNP, then tax cuts may, by increasing the demand for money, depress aggregate demand. We examine a variety of evidence and...

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...

This paper discusses nominal income targeting as a possible rule for the conduct of monetary policy. We begin by discussing why a rule for monetary policy may be desirable and the characteristics that a good rule should have. We emphasize, in particular, three types of nominal income targets,...

This paper examines the choice of monetary policy in response to seasonal fluctuations in the economy. It discusses the costs and benefits of smoothing interest rates over the seasons, which has been the Fed's policy since its founding in 1914, and presents simulations suggesting how the economy...

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...
