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 … a necessary and sufficient condition. It simultaneously drives sorting and functions as a single-crossing property …
