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...

Punishment can lose its legitimacy if the enforcer can profit from delivering punishment. We examine how justification can promote the legitimacy of punishment in a one-shot sender-receiver game where an independent third party can punish the sender upon seeing whether the sender lied. Most...

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...

We study the long-run stochastic stability properties of volunteering strategies in finite populations. We allow for mixed strategies, characterized by the probability that a player may not volunteer. A pairwise comparison of evolutionary strategies shows that the strategy with a lower...

We study conflict between two groups of individuals. Using Schaffer's (1988) concept of evolutionary stability we provide an evolutionary underpinning for in-group altruism combined with spiteful behavior towards members of the rival out-group. We characterize the set of evolutionarily stable...

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...
