Utility-refined and budget-refined ɛ-competitive equilibria
在有限可加交换经济中，标准竞争均衡可能不存在，因此需要ɛ-竞争均衡概念。本文研究了两种ɛ-竞争均衡概念之间的关系。
In finitely additive exchange economies the usual definition of competitive equilibrium can result in an empty equilibrium set, and therefore one has to consider notions of ɛ-competitive equilibria. In this paper we investigate the relationship between two notions of ɛ-competitive equilibria.
