Ideal equilibria in noncooperative multicriteria games
TL;DR: This paper proposes ideal equilibria, strategy profiles that are robust against unilateral deviations of the players no matter what importance is assigned to the criteria, and provides a non-trivial class of multicriteria games in which idealequilibria exist.
Journal ArticleDOI
Cost allocation in shortest path games
Mark Voorneveld,Sofia Grahn +1 more
TL;DR: The core allocations of the cooperative shortest path game coincide with the payoff vectors in the strong Nash equilibria of the associated noncooperative shortest pathgame.
Journal ArticleDOI
Monotonic Allocation Schemes in Clan Games
TL;DR: In this article, the authors characterized total clan games using monotonicity, veto power of the clan members, and a concavity condition reflecting the decreasing marginal contribution of non-clan members to growing coalitions.
Journal ArticleDOI

Sofia Grahn,Mark Voorneveld +1 more
TL;DR: Rules satisfying these axioms are shown to yield population monotonic allocation schemes and the thieve property for bankruptcy problems.

Core and bargaining set of shortest path games
TL;DR: In this article, it was shown that the core and bargaining sets of Davis-Maschler and Zhou coincide in a class of shortest path games, and that the bargaining set of Zhou and Davis coincide in the same class of games.
