The matching of likes is a frequently observed phenomenon. However, for such assortative matching to arise in a search … can generate even perfect assortative matching under weak conditions: supermodularity of the match production function is … the model achieves nearly unconstrained efficiency despite frictions. -- Assortative matching ; sorting ; search ; signals …

We prove existence of steady-state equilibrium in a class of matching models with search frictions. …

assortative matching. Frictions are commonly understood to hamper sorting. Instead, we show how frictions generate positive … sorting even with a submodular production function. Our results challenge the interpretation of positive assortative matching …

We propose a parsimonious matching model where people's choice of whom to meet endogenizes the degree of randomness in … matching. The analysis highlights the interaction between a productive motive, driven by the surplus attainable in a match, and …
