This paper provides nonparametric identification results for a class of latent utility models with additively separable unobservable heterogeneity. These results apply to existing models of discrete choice, bundles, decisions under uncertainty, and matching. Under an independence assumption,...

We extend the result from Bossert and Sprumont (2013) that every single-valued choice function is backwards-induction rationalizable via strict preferences to the case of choice correspondences via weak preferences.
