On the maximal domain theorem: A corrigendum to “Walrasian equilibrium with gross substitutes”

Abstract

The maximal domain theorem by Gul and Stacchetti (1999) shows that for markets with indivisible objects, the set of gross substitutable preferences is a largest set for which the existence of a competitive equilibrium is guaranteed. In this paper, we give an example to show that a claim in their proof is false, and provide an alternative proof based on a new characterization of gross substitutability.
