This paper investigates economic efficiency under non-convexity. The analysis relies on a generalization of the … separating hyperplane theorem under non-convexity. The concept of zero-maximality is used to characterize Pareto efficiency under … non-convexity. We show the existence of a separating hypersurface that can be used to provide a dual characterization of …
