This paper studies the productivity implications of the cyclical reallocation of capital. Frictions in the reallocation process are a source of factor misallocation. Cyclical movements in these frictions lead to variations in the degree of reallocation and thus in productivity. These frictions...

We study labor adjustment costs. We specify a dynamic optimization problem at the plant-level, allowing for both convex and non-convex adjustment costs. We estimate the parameters of the adjustment process using an indirect inference procedure in which simulated moments are matched with data...

This paper studies quantitative implications of model economies that exhibit multiple equilibria. The goal is to assess two interrelated issues. First, do economies with multiple equilibria have falsifiable predictions? Second, is identification possible in economies that exhibit multiple...

While the European Monetary Union (EMU) is now a reality, debate among economists nonetheless continues about the design and desirability of monetary unions. Since an essential element of a monetary union is the delegation of monetary power to a single centralized entity, one of the key issues...

This paper looks at recent advances in the study of aggregate fluctuations. Our emphasis is on three prominent areas of research: the stochastic growth model, economies which exhibit macroeconomic complementarities and models that emphasize heterogeneity. Each section of the paper outlines the...

We study the inferences about labor adjustment costs obtained by the 'gap methodology' of Caballero and Engel [1993] and Caballero, Engel and Haltiwanger [1997]. In that approach, the policy function of a manufacturing plant is assumed to depend on the gap between a target and the current level...

This paper studies the nature of capital adjustment at the plant-level. We use an indirect inference procedure to estimate the structural parameters of a rich specification of capital adjustment costs. In effect, the parameters are optimally chosen to reproduce the nonlinear relationship between...
