A central aspect of strategic reasoning in sequential games consists in anticipating how co-players would react to information about past play, which in turn depends on how co-players update and revise their beliefs. Several notions of belief system have been used to model how players’ beliefs...

We extend the war of attrition by studying a three-period dynamic contest game. In our game, players can fight against their opponents at certain period of the contest and can flee at any time. Waiting is costly. We focus on the role of waiting costs and show that the value of waiting costs is a...

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 propose a concept of quantum extensive-form games, which is a quantum extension of classical extensive-form games. Extensive-form games is a general concept of games such as Go, Shogi, and chess, which have triggered the recent AI revolution, and is the basis for many important game theoretic...

We investigate a process of decision-making in a multi-period winner-take-all contest, in which competing players simultaneously choose among actions with different levels of risk every period. Strategic risk-taking is analyzed in isolation from effort choices, and, according to expected utility...

In a tournament, agents form coalitions, and the coalition with largest power wins the tournament. We introduce a new solution concept for the tournaments, called no threat equilibrium (NTE). NTE is a partition of the agents, where prudent and farsighted agents have no incentive to deviate....

We consider a model of common-value sequential voting in which voters are differentiated in their information. We ask whether the intuition as in the simultaneous-voting case---voters with no information would vote so as not to influence the outcome---would be valid to imply long voting in our...

We investigate whether tournament prizes that depend on joint output ("variable prize tournaments") can alleviate the sabotage problem which is otherwise inherent in tournament struc- tures. In a game-theoretical model with three contestants, we compare fixed-prize tournaments with tournaments...
