This paper first outlines the key stylized facts about changes in inflation dynamics in recent years: 1) inflation persistence has declined, 2) the Phillips curve has flattened, and 3) inflation has become less responsive to other shocks. These changes in inflation dynamics are interpreted as...

Inflation equals the product of two terms: an extensive margin (the fraction of items with price changes) and an intensive margin (the average size of those price changes). The variance of inflation over time can be decomposed into contributions from each margin. The extensive margin figures...

Unconditional reduced form estimates of a conventional wage Phillips curve for the U.S. economy point to a decline in its slope coefficient in recent years, as well as a shrinking role of lagged price inflation in the determination of wage inflation. We provide estimates of a conditional wage...

We give a thorough analytic characterization of a large class of sticky-price models where the firm’s price setting behavior is described by a generalized hazard function. Such a function provides a tractable description of the firm’s price setting behavior and allows for a vast variety of...

We implement a new approach for the identification of news shocks about future technology. In a VAR featuring a measure of aggregate technology and several forward-looking variables, we identify the news shock as the shock orthogonal to technology innovations that best explains future variation...

Over the past thirty years, a great deal of business cycle research has been based on purely real models that abstract from the presence of nominal rigidities, and so (at least implicitly) assume that the Phillips curve is vertical. In this paper, I show that such models are fragile, in the...

The present paper provides an overview of recent developments in the analysis of monetary policy in the presence of nominal rigidities. The paper emphasizes the existence of several dimensions in which the recent literature provides a new perspective on the linkages among monetary policy,...

We develop an analytically tractable Phillips curve based on state-dependent pricing. We differ from the existing literature by considering a local approximation around a zero inflation steady state and introducing idiosyncratic shocks. The resulting Phillips curve is a simple variation of the...

We study the international monetary policy design problem within an optimizing two-country sticky price model, where each country faces a short run tradeoff between output and inflation. The model is sufficiently tractable to solve analytically. We find that in the Nash equilibrium, the policy...

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...
