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...

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...

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...

"This paper explores the influence of some key institutional features of the labour market on aggregate fluctuations. It uses a dynamic, stochastic, general equilibrium model characterised by search and matching frictions in the labour market and nominal rigidities in the goods market. It finds...
