This paper introduces a notion of firm size into a search and matching model with endogenous job destruction. The outcome is a rich, yet analytically tractable framework that can be used to analyze a broad set of features of both the cross-section and aggregate dynamics of the labor market. The...

One of the strongest trends in recent macroeconomic modeling of labor market fluctuations is to treat unemployment inflows as acyclical. This trend stems in large part from an influential paper by Shimer on "Reassessing the Ins and Outs of Unemployment," i.e., the extent to which increased...

This paper studies the analytics of a canonical model of fixed adjustment costs in the presence of idiosyncratic productivity shocks. We provide a novel analytical characterization of the steady state and dynamics of aggregate outcomes implied by the model. The dynamics are shown to have an...

This paper uses plant-level data to document the joint adjustment of capital and employment. The data are analyzed through the lens of a model that integrates features from influential theories of costly capital and labor adjustment. Although the model is rich enough to account for several...

This paper studies individual and plant-wide adjustment in days worked. Matched firm-worker data for North-East Italy show signicant variation in mean days worked per month within plants: a one-standard deviation change amounts to about four days of worker per month. The paper then looks within...

This paper studies price and quality differences across international intermediate input suppliers. We develop price measures that account for (i) differences in product characteristics, (ii) unobserved quality differences, and (iii) pure (frictional) price dispersion across suppliers. Using...

In this paper, we examine three famous episodes of deliberate deflation (or disinflation) in U.S. history, including episodes following the Civil War, World War I, and the Volcker disinflation of the early 1980s. These episodes were associated with widely divergent effects on the real economy,...

We study cross-country differences in price and quality in the market for semiconductor wafer manufacturing services. Using a proprietary transaction-level data set, we document i) substantial constant-quality price differences across suppliers, and ii) shifts toward lower priced suppliers....
