On the coincidence of the prenucleolus and the Shapley value

We extend the literature on the coincidence of the prenucleolus and the Shapley value, by identifying a class of coalitional form games called PS games. We analyse the role of PS games in the context of queueing problems, and show that in the class of generalized queueing games only those queueing games with 'linear externalities' are PS games.
