Abstract
The property of Weak Gross Substitutibility (WGS) of goods in a market has been found to be conducive to efficient algorithms for finding equilibria. In this paper, we give a natural definition of a δ-approximate WGS property, and show that the auction algorithm of [GK04][GKV04] can be extended to give an (ε + δ)-approximate equilibrium for markets with this property.
