On two solution concepts in a class of multicriteria games

Abstract

In this paper we compare two solution concepts for general multicriteria zero-sum matrix games: minimax and Pareto-optimal security payoff vectors. We characterize the two criteria based on properties similar to the ones that have been used in the corresponding counterparts in the single criterion case, although they need to be complemented with two new consistency properties. Whereas in standard single criterion games minimax and optimal security payffs coincide, whenever we have multiple criteria these two solution concepts differ. We provide explanations for the common roots of these two concepts and highlight the intrinsic differences between them.
