Order Monotonic Solutions for Generalized Characteristic Functions [PDF]

open access: yesSSRN Electronic Journal, 2013
Generalized characteristic functions extend characteristic functions of 'classical' TU-games by assigning a real number to every ordered coalition being a permutation of any subset of the player set. Such generalized characteristic functions can be applied when the earnings or costs of cooperation among a set of players depend on the order in which the
