We study the marginal worth vectors and their convex hull, the socalled Weber set, from the original coalitional game and the transformed one, which is called the Weber set of level k. We prove that the core of the original game is included in each of the Weber set of level k, for any k, and...

Convex cooperative games were first introduced by Shapley (Int J Game Theory 1:11–26, <CitationRef CitationID="CR11">1971</CitationRef>) while population monotonic allocation schemes (PMAS) were subsequently proposed by Sprumont (Games Econ Behav 2:378–394, <CitationRef CitationID="CR13">1990</CitationRef>). In this paper we provide several characterizations of convex games and...</citationref></citationref>
