We consider cooperative environments with externalities (games in partition function form) and provide a recursive definition of dividends for each coalition and any partition of the players it belongs to. We show that with this definition and equal sharing of these dividends the averaged sum of...

This paper presents synthetically some recent developments in the theory of coalition and network formation. For this purpose, some major equilibrium concepts recently introduced to model the formation of coalition structures and networks among players are briefly reviewed and discussed. A few...

I present a model in which the players of a game have the option to delegate parts of their strategies to a third party who has an interest in the outcome of the game. I analyze whether the game with delegation to a common agent improves over the equilibrium of the original game. This paper...
