The attack and defense game is a game in which an attacker (a group of attackers) has an incentive to revise the status quo and a defender (a group of defenders) wants to protect it. The asymmetry in objectives creates incompatible interests and results in a mixed-strategy Nash equilibrium....

We examine theoretically and experimentally how combining between-team and within-team incentives affects behavior in team tournaments. Theory predicts that free-riding is likely to occur when there are only between-team incentives, and offering within-team incentives may solve this problem....

Within-group communication in competitive coordination games has been shown to increase competition between groups and lower efficiency. This study further explores potentially harmful effects of communication, by addressing the questions of (i) asymmetric communication and (ii) the endogenous...

Many economic interactions rely on trust, which is sometimes violated. The fallout from business fraud and other malfeasance shows serious economic consequences of trust violations. Simple rules mandating minimum standards are attractive because they prevent the most egregious trust violations....

Motivated by the analyst and investor setting we examine the behavior of subjects playing both roles of sender and receiver in an information transmission game. We also elicit the subjects' beliefs of others' strategic behavior, risk and other-regarding preferences. The results of the experiment...

Costless pre-play communication has been shown to effectively facilitate within-group coordination. However, in competitive coordination games, such as rent-seeking contests, better within-group coordination leads to more aggressive competition and lower efficiency. We report an experiment in...

Despite normative predictions from economics and biology, unrelated strangers will often develop the trust necessary to reap gains from one-shot economic exchange opportunities. This appears to be especially true when declared intentions and emotions can be cheaply communicated. Perhaps even...

Standard theoretical prediction is that rational economic agents participating in rent-seeking contests should engage in socially inefficient behavior by exerting costly efforts. Experimental studies find that the actual efforts of participants are significantly higher than predicted and that...

Contests are well-established mechanisms for political lobbying, innovation, rentseeking, incentivizing workers, and advancing R&D. A well-known theoretical result in the contest literature is that greater heterogeneity decreases investments of contestants because of the "discouragement effect."...
