This discussion paper led to a publication in 'TOP' (forthcoming).<P> In this paper we introduce and characterize two new values for transferable utility games with graph restricted communication and a priori unions. Both values are obtained by applying the Shapley value to an associated TU-game....</p>

This discussion paper resulted in a publication in the 'Annals of Operations Research' (forthcoming).<P> We introduce an Owen-type value for games with two-level communication structures, being structures where the players are partitioned into a coalition structure such that there exists restricted...</p>

This discussion paper led to the article with the same title in 'Social Choice and Welfare' (2014), 43, 173-194.<P> We consider the problem of sharing water among agents located along a river. Each agent has quasi-linear preferences over river water and money, where the benefit of consuming an...</p>

This discussion paper resulted in a publication in <I>Annals of Operations Research </I>, 2015, 225, 27-44.<P> This paper analyzes Harsanyi power solutions for cooperative games in which partial cooperation is based on union stable systems. These structures contain as particular cases the widely studied...</p></i>

A situation in which a finite set of agents can generate certain payoffs by cooperation can be described by a cooperative game with transferable utility (or simply a TU-game) where each agent is represented by one player in the game. In this paper, we assume that one agent can be represented by...

Although the principles of Exclusion and Exemption are...</p>

A (point-valued) solution for cooperative games with transferable utility, or simply TU-games, assigns a payoff vector to every TU-game. In this paper we discuss two classes of equal surplus sharing solutions, one consisting of all convex combinations of the equal division solution and the...

We consider the problem of axiomatizing the Shapley value on the class of assignment games. We first show that several axiomatizations of the Shapley value on the class of all TU-games do not characterize this solution on the class of assignment games by providing alternative solutions that...

This discussion paper resulted in a publication in the 'Economic Theory', 2015, 58, 99-123.<P> In the literature various models of games with restricted cooperation can be found. In those models, instead of allowing for all subsets of the set of players to form, it is assumed that the set of...</p>

This discussion paper resulted in a publication in 'Games and Economic Behavior', 2012, 76, 344-348. <P> Three well-known solutions for cooperative TU-games are the Shapley value, the Banzhaf value and the equal division solution. In the literature various axiomatizations of these solutions can be...</p>
