Box 20-8281, New Haven, CT 06520-8281, USA (e-mail: ori.haimanko@yale.edu), US aut Value theory without symmetry [Elektronische Daten] [Ori Haimanko] Abstract.: We investigate quasi-values of finite games - solution concepts that satisfy the axioms of Shapley (1953) with the possible exception of symmetry.  Following Owen (1972), we define "random arrival'', or path, values: players are assumed to "enter'' the game randomly, according to independently distributed arrival times, between 0 and 1; the payoff of a player is his expected marginal contribution to the set of players that have arrived before him.  The main result of the paper characterizes quasi-values, symmetric with respect to some coalition structure with infinite elements (types), as random path values, with identically distributed random arrival times for all players of the same type.  General quasi-values are shown to be the random order values (as in Weber (1988) for a finite universe of players).  Pseudo-values (non-symmetric generalization of semivalues) are also characterized, under different assumptions of symmetry.
