This paper analyzes the possibility of irnplementing stable outcomes for marriage markets. Our first result shows a contradiction between the use of stable mechanisins and the hypotesis of agents' behaviour consiclered in the Nash equilibriurn concept . We analyze the possibility of...

This paper studies a class of NTU coalition formation games in which every player's payoff depends only on the members of her coalition. We identify four natural conditions on individuals' preferences and show that, under each condition, stable (core) allocations exists.

This paper explores the existence of stable research teams, when each agent's preferences depend on the set of researchers collaborating with her. We introduce a property over researchers' preferences, called tops responsiveness guaranteeing the existence of stable research teams configurations....

This paper introduces a property over agents' preferences, called Tops Responsiveness Condition. Such a property guarantees that the core in Hedonic Coalition Formation games is not empty. It is also shown that a mechanism exists that selects a stable allocation. It turns out that this...
