Supportability, Sustainability, and Subsidy-Free Prices
研究无补贴价格、匿名公平价格、可支持性与可持续性之间的关系，给出这些概念非空的条件，并证明存在匿名公平且可持续的Aumann-Shapley价格向量。
This article studies the relationships among the concepts of subsidy-free prices, anonymously equitable prices, supportability, and sustainability. In particular, we set out conditions under which these concepts are not vacuous. Several new sets of conditions under which a subsidy-free price vector is sustainable are also presented. For general, nonseparable demands, we establish the existence of an Aumann-Shapley price vector that is anonymously equitable and sustainable.
