We introduce different skill groups and production functions into the Burdett-Mortensen equilibrium search model. Supermodularity in the production process leads to a positive intrafirm wage correlation between skill groups. Theory implies that increasing returns to scale can lead to a unimodal...

We introduce skill groups and different production technologies into the Burdett-Mortensen model of on the job search. Supermodularity of the different skill groups in the production process leads to a positive intra-firm wage correlation between skill groups. Increasing returns to scale allow...

Social contacts help workers to find jobs, but those jobs need not be in the occupations where workers are most productive. Hence social contacts can generate mismatch between a worker's occupational choice and his comparative productive advantage. Thus economies with dense social networks can...

In a simple search model of money, we study a special kind of memory which gives rise to an arrangement resembling a payment network. Specifically, we assume that agents can choose to have access to a central data base which keeps track of payments made and received. We show that multiple...

This paper extends Shimer's (2005) Mismatch model to allow for endogenous mobility. Rather than work directly in the original model, I use a related framework, the stock-flow matching model (Taylor, 1995; Coles and Muthoo, 1998). One of the contributions of this paper is therefore to compare the...

We introduce a joint model of labor market search and firm size dynamics to explain the differential in labor market and productivity outcomes between the U.S. and the European Union. At the core, our model is a hybrid of the labor market search model by Mortensen and Pissarides (1994) and the...
