We introduce the prediction value (PV) as a measure of players' informational importance in probabilistic TU games. The latter combine a standard TU game and a probability distribution over the set of coalitions. Player i's prediction value equals the difference between the conditional...

This discussion paper led to a publication in 'Mathematical Methods of Operations Research', 59, 147-166. <P> Cooperative games on antimatroids are cooperative games restricted by a combinatorial structure which generalize the permission structure. So, cooperative games on antimatroids group...</p>

This discussion paper resulted in a publication in 'Games and Economic Behavior', 2010, 68, 626-633. <P> We study cooperative games with communication structure, represented by an undirected graph. Players in the game are able to cooperate only if they can form a network in the graph. A...</p>
