The directed search model (Peters, 1984) is static; its dynamic extensions typically restrict strategies, often assuming price or match commitments. We lift such restrictions to study equilibrium when search can be directed over time, without constraints and at no cost. In equilibrium trade...

In an experiment, a group of strangers was randomly divided in pairs to play a prisoners’ dilemma; this process was indefinitely repeated. Cooperation did not increase when subjects could send public messages amounting to binding promises of future play.

We study the individual behavior of students and workers in an experiment where they repeatedly face the same cooperative task. The data show that clerical workers differ from college students in overall cooperation rates, strategy adoption and use of punishment opportunities. Students cooperate...

We study a decentralized trading model as in Peters (1984), where heterogeneous market participants face a trade-o between price and trade probability. We present a novel proof of existence of a unique demand vector in Nash equilibrium, based on a recursive approach that exploits the...

Impersonal exchange is the hallmark of an advanced society. One key institution for impersonal exchange is money, which economic theory considers just a primitive arrangement for monitoring past conduct in society. If so, then a public record of past actions—or memory—supersedes the function...

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...

In this paper, we generalize the General Lotto game (budget constraints satisfied in expectation) and the Colonel Blotto game (budget constraints hold with probability one) to allow for battlefield valuations that are heterogeneous across battlefields and asymmetric across players, and for the...

We experimentally investigate the effect of social identification and information feedback on individual behavior in contests. Identifying subjects through photo display decreases efforts. Providing information feedback about others’ effort does not affect the aggregate effort levels but it...

We design an experiment to explore the impact of earned entitlements on the frequency and intensity of conflicts in a two-stage bargaining and conflict game with side-payments. In this game, residents (Proposers) make side-payment offers and contestants (Responders) decide whether to accept the...

This study examines behavior of subjects in simultaneous and sequential multi-battle contests. In simultaneous contests, subjects make positive bids in each battle 80% of the time and bids fall within the predicted boundaries. However, 35% of the time subjects make positive bids in only two,...
