The Lorenz-Pareto Optimal Frontier of a collective choice problem indentifies a (usually quite large) subset of all Pareto optimal outcomes which are not inegalitarian according to the Lorenz criterion. We study the basic properties of Lorenz-Pareto optimal choice functions and in particular...

This paper studies the conditions under which the basic results of the re vealed preference theory can be established on the domain of choice problems which include non-convex feasible sets, the exercice is closely related to the works of Peters and Wakker (1991) and Bossert (1994).
