We consider rules (strategies, commitments, contracts, or computer programs) that make behavior contingent on an opponent’s rule. The set of perfectly observable rules is not well defined. Previous contributions avoid this problem by restricting the rules deemed admissible. We instead limit...

Recent insights from the ‘embodied cognition’ perspective in cognitive science, supported by neural research, provide a basis for a ‘methodological interactionism’ that transcends both the methodological individualism of economics and the methodological collectivism of (some) sociology,...

In this paper we study the effects of providing additional feedback about individual contributions and earnings on the dynamics of contributions in a repeated public good game. We include treatments where subjects can freely choose whether to obtain additional information about individual...

We use a novel experimental design to examine the role of reputational concerns in explaining conditional cooperation in social dilemmas. By using the strategy method in a repeated sequential prisoners’ dilemma in which the probabilistic end is known, we can distinguish between strategically...

Mediation is a conflict resolution method in which a third neutral party provides assistance to the conflict parties.The process of mediation as well as any solution to the conflict arising from it is implemented only by the consent of all conflict parties.It is the role of a mediator to...

We isolate strategic and non-strategic motivations of sanctioning in a repeated public goods game. In two experimental treatments, subjects play the public goods game with the possibility to sanction others. In the STANDARD sanctions treatment, each subject learns about the sanctions received in...

In this paper we measure experienced guilt in a prisoner’s dilemma experiment with pre-play communication. We find that feelings of guilt only arise in the case of unilateral defection and that they are stronger when players have mutually agreed to cooperate. We also find that fining...

If contract enforcers must be randomly selected from the same population and thus are as opportunistic as ordinary traders could a system of adjudication nevertheless increase the degree to which contractual obligations on large anonymous markets are fulfilled? Adopting an indirect evolutionary...

We explore the incentives countries face in trade litigation within the new WTO Dispute Settlement System. Our analysis yields a number of interesting predictions. First, because sanctions are ruled out during the litigation process, the Dispute Settlement System does not preclude all new trade...
