Further open problems in cooperative games

In 2013, the International Game Theory Review published two special issues on open problems in cooperative games: the first regarding theory (Fragnelli and Gambarelli, 2013a) and the second applications (Fragnelli and Gambarelli, 2013b). In this paper, our aim is to present some problems currently “on our table†that were not included in the two issues mentioned above, either because the topics were too specific or they arose after publication. The problems are divided into theoretical problems, general models that may be applied to different fields and applicative problems.
