We extend Vind's classical theorem on the measure of blocking coalitions valid in finite dimensional atomless economies … general class of Aubin coalitions for which a suitable version of Grodal's result ([17]) is also formulated. Our results wish … to point out the relevance of cone conditions dealing with blocking coalitions of arbitrary measure or weight. …

In a static context it has already been shown that it is possible to achieve stability in the sense of the core of a … paper provides a transfer scheme that yields a core property in a dynamic context. The possibility of computing such …

A coalitional matching is a two-sided matching problem in which agents on each side of the market may form coalitions … would like to learn from. In this setup, we examine how the existence of core stable partitions on the distinct market sides … respect common rankings shape the existence of core stable coalitional matchings. …
