Abstract:A demand correspondence with a closed-valued inverse can be rationalized by some preference relation if and only if it is homogeneous of degree zero, has the Nash-Chernoff independence property, and its inverse is convex valued. The proof is constructive and the derived preference rationalization is continuous if the demand correspondence has a closed graph.
