Abstract

Mediation is a key strategic instrument for managing conflicts in bargaining scenarios with incomplete information. This paper reports the first systematic laboratory investigation into the informed principal problem concerning mediator selection. The theory of neutral optimum predicts that, in our environment, the informed principal's most reasonable choice is not the mediator that maximizes the ex-ante probability of peace; rather, the one preferred by the stronger type alone constitutes a credibly justifiable compromise between the conflicting interests of different types. We find that subjects do not choose the neutral mediator more often than the peace-maximizing one. Different principal types recognize the need for inscrutable selection and form intertype compromises, and they systematically view the peace-maximizing mediator as the more compelling compromise. The strategic reasoning underlying the neutral optimum fails to materialize in the lab.
