We show how to nonparametrically identify the distribution of heterogeneity using the linear independence of a class of structural economic choice models. We state an economic property known as reducibility and prove that reducibility ensures linear independence and hence identi cation. Reducibility makes verifying the identi cation of nonlinear models easy. We can allow for a nonparametric dis...
