An Extension of the Second Welfare Theorem to Economies with Nonconvexities and Public Goods
将Foley和Guesnerie关于第二福利定理的结果推广到具有任意非凸生产集的经济体，并利用Clarke切锥阐明了边际成本价格的性质。
In this paper we report a generalization of the results of Foley and Guesnerie on the second welfare theorem to economies with arbitrary nonconvex production sets. The nature of marginal cost prices in such economies is clarified through the use of the Clarke tangent cones.
