Consider Becker's 1973 classic matching model, with unobserved fixed types and stochastic publicly observed output. If … types are complementary, then matching is assortative in the known Bayesian posteriors (the 'reputations'). We discover a … robust failure of Becker's result in the simplest dynamic two type version of this world. Assortative matching is generally …
