During the last three decades, jobs in the middle of the skill distribution disappeared, and employment expanded for high- and low-skill occupations. Real wages did not follow the same pattern. Although earnings for the high-skill occupations increased robustly, wages for both low- and...

Using data on border enforcement and macroeconomic indicators from the United States and Mexico, we estimate a two-country business cycle model of labor migration and remittances. The model matches the cyclical dynamics of unskilled migration and documents the insurance role of remittances in...

We develop a quantitative business cycle model with search complementarities in the inter-firm matching process that entails a multiplicity of equilibria. An active equilibrium with strong joint venture formation, large output, and low unemployment coexists with a passive equilibrium with low...

The emergence of global value chains not only leads to a magnification of trade in intermediate inputs but also to an extensive technology diffusion among the different production units involved in arms-length relationships. In this context, the lack of enforcement of intellectual property...

We incorporate remittances and microentrepreneurship (self-employment) into a small open-economy business cycle model with capital and labor market frictions. Countercyclical remittances moderate the decline of households' consumption during recessions. These remittances also are used to finance...

During the last thirty years, labor markets in advanced economies were characterized by their remarkable polarization. As job opportunities in middle-skill occupations disappeared, employment opportunities concentrated in the highest- and lowest-wage occupations. I develop a two-country...

Recent empirical evidence establishes that a positive technology shock leads to a decline in labor inputs. Can a flexible price model enriched with labor market frictions replicate this stylized fact? We develop and estimate a standard flexible price model using Bayesian methods that allows, but...

This paper develops a dynamic general equilibrium model with heterogeneous firms that face search complementarities in the formation of vendor contracts. Search complementarities amplify small differences in productivity among firms. Market concentration fosters monopsony power in the labor...

Recent empirical evidence suggests that a positive technology shock leads to a decline in labor inputs. However, the standard real business cycle model fails to account for this empirical regularity. Can the presence of labor market frictions address this problem without otherwise altering the...

We build a model with a traditional banking system, endogenous entry of firms and fintech intermediaries, and firm heterogeneity in credit access and usage to study the credit-market, macroeconomic, and business cycle implications of the recent sizable growth in the number of fintech...
