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 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...

We document a steady decline in low-skilled immigration that began with the onset of the Great Recession in 2007, which was associated with labor shortages in low-skilled service occupations and a decline in the skill premium. Falling returns to high-skilled jobs coincided with a decline in the...
