This paper discusses the core of the game corresponding to the standard fixed tree problem. We consider the weighted adaptation of the constrained egalitarian solution of Dutta and Ray (1989). The core of the standard fixed tree game equals the set of all weighted constrained egalitarian...

Nash equilibria for strategic games were characterized by Peleg and Tijs (1996) as those solutions satisfying the properties of consistency, converse consistency and one-person rationality. <p> There are other solutions, like the -Nash equilibria, which enjoy nice properties and appear to be...</p>

This article considers single-valued solutions of transferable utility cooperative games that satisfy core selection and aggregate monotonicity, defined either on the set of all games, G <Superscript> N </Superscript>, or on the set of essential games, E <Superscript> N </Superscript> (those with a non-empty imputation set). The main result is that...</superscript></superscript>
