Assortative Matching and Search

This paper has pushed Becker's matching insights into a quite plausible search setting. Exploiting the implicit integral equation (10), we gave a thorough characterization of cross-sectional matching patterns in the equilibrium and constrained s ocial optimum of a frictional matching model. In so doing, we have developed important new techniques for establishing existence, as well as extended the reach of the supermodularity research program into a wide new arena.
