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...

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...

We document a slowdown in low-skilled immigration that began around the onset of the Great Recession in 2007, which was associated with a subsequent rise in low-skilled wages, a decline in the skill premium, and labor shortages in service occupations. Falling returns to education also coincided...

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...

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...

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...

This paper studies the impact of skilled immigration policy frictions in the United States on technology-intensive firms by age cohorts. We use firm-level data and a general equilibrium model with endogenous firm entry and exit. The empirical results show that skilled immigration policy...

Using data for El Salvador and Bayesian techniques, we develop and estimate a two-sector dynamic stochastic general equilibrium model to analyze the effects of remittances in emerging market economies. We find that, whether altruistically motivated or otherwise, an increase in remittance flows...

This paper studies the cyclical pattern of ex post markups in the banking system using balance-sheet data for a large set of countries. Markups are strongly countercyclical even after controlling for financial development, banking concentration, operational costs, inflation, and simultaneity or...

In this paper, we first introduce investment-specific technology (IST) shocks to an otherwise standard international real business cycle model and show that a thoughtful calibration of them along the lines of Raffo (2009) successfully addresses the quantity, international comovement,...
