Destination countries can adopt selective immigration policies to improve migrants' quality. Screening potential migrants on the basis of observable characteristics also influences their self-selection on unobservables. We propose a model that analyzes the effects of selective immigration...

We study a structural model of R&D alliance networks in which firms jointly form R&D collaborations to lower their production costs while competing on the product market. We derive the Nash equilibrium of this game, provide a welfare analysis and determine the optimal R&D subsidy program that...

We investigate the role of spatial frictions in search equilibrium unemployment. For that, we develop a model of the labor market in which workers? location in an agglomeration depends on commuting costs, the endogenous price of land and the value of job search and employment. We first show that...
