The ultimatum heuristic is a decision-making tendency discernible in graphical plots of mixed-motive noncooperative games. As such, it can serve also as a solution approach, backsolving, predicting and explaining outcomes better than the mainstay Nash equilibrium concept whenever data for the...

We study the decision process in a group dictator game in which three subjects can distribute an initial endowment between themselves and a group of recipients. The experiment consists of two stages: first, individuals play a standard dictator game. Second, individuals are randomly matched into...

Mixed-motive noncooperative games feature ambivalence in the competitive relation of the players and outcomes disobliging Nash equilibrium prescription. The Nash approach, ostensibly rational and self-maximizing, regularly advises strategy many players regard as counterintuitive or faulty. And...

This paper models the coalition formation process among primates as a sequential game. The population consists of primates having distinct social ranks. The rank of each individual is determined by his resource holding potential. Each member of the population is interested in gaining access to a...

We apply three equilibrium selection techniques to study which equilibrium is selected in a hawk-dove game with a multiplicity of equilibria. By using a uniform-price auction as an illustrative example, we find that when the demand in the auction is low or intermediate, the tracing procedure...

In this paper we provide sufficient conditions for a social choice rule to be implementable in strong Nash equilibrium in the presence of partially honest agents, that is, agents who break ties in favor of a truthful message when they face indifference between outcomes. In this way, we achieve a...
