We aim at characterizing which kind of functions could be explained (rationalized) as the best reply of payoff-maximizing agents in contests for a fixed prize. We show that the rationalizability strongly differs between Decisive Contests, where the prize is allocated with certainty, and Possibly...

We study a dynamic volunteering dilemma game in which two players choose to volunteer or wait given there have not been any volunteering actions in the past. The players can be procrastinators and the benefits of volunteering arrive later than the costs. We fully characterise the stationary...

We propose a belief-based theory for private information games. A Bk player forms correct beliefs up to the k^th-order, and heuristic beliefs from the (k +1)^th-order onwards. Correct beliefs follow the prior distribution of types, as in standard game theory. Heuristic beliefs ignore the...

Drawing upon the Bayesian persuasion literature, I show that a mediator can provide conflicting parties strategically with information to decrease the ex-ante war probability. In a conflict between two parties with private information about military strength, the mediator generates information...

This paper considers evolutionarily stable strategies (ESS) in a take-it-or-leave-it offer bargaining game with incomplete information. We find responders reject offers which yield a higher positive material payoff than their outside option. Proposers, in turn, make more attractive offers than...

Previous experimental results on one-shot sequential two-player games show that group decisions are closer to the subgame-perfect Nash equilibrium than individual decisions. We extend the analysis of inter-group versus inter-individual decision making by running both one-shot and repeated...

The literature on aggregative games, which has been applied in the study of contests, has focused on simultaneous games. We apply aggregative games techniques in a novel fashion in the analysis of sequential lottery contests with n players. It is shown that: (1) there exists a unique subgame...

In many real-world contests (political elections / lobbying for public projects), contestants try to engage supporters (unemployed youth / local residents) to fight for them. Such contests have the following features: a significant part of a contestant's supporter compensation is contingent upon...

In the world of satin bowerbirds, the male-birds engage in a contest among themselves to win their mates: they spend considerable time and effort in decorating their own bowers, and then attempt to destroy the decorations of their rivals' bowers. The female-birds, in turn, select their mates on...

We conduct an experiment to examine the role of retribution and deterrence in motivating third party punishment. In particular, we consider how the role of these two motives may differ according to whether a third party is a group or an individual. In a one-shot prisoner's dilemma game with...
