A Class of Convex Preferences Without Concave Representation

Paulo Monteiro

Revista Brasileira de Economia - RBE, 2010, vol. 64, issue 1

Abstract: I show that continuous convex preference relations that have affine indifference curves do not have a concave representation if there are two indifference curves that are not parallel. In other words a preference relation with affine indifference curves that has a concave representation has a linear utility representation.
