Existence of Marginal Cost Pricing Equilibria: The Nonsmooth Case.

In this article, the authors report a general existence theorem of a marginal (cost) pricing equilibrium for an economy that may exhibit increasing returns to scale or more general types of nonconvexities in the production sector. Their model considers an arbitrary number of firms and no smoothness assumption is made on the production sets or on the aggregate production set.
