Forschungszentrum für Umweltökonomik (FZU)


Das Forschungszentrum für Umweltökonomik (FZU) am Alfred-Weber-Institut dient als gemeinsame Plattform für Ökonomen, die alle an der Schnittstelle von natürlicher Umwelt und Wirtschaft forschen. Wir nutzen theoretische, empirische und experimentelle Methoden, um die Herausforderungen nachhaltigen Umgangs mit der Umwelt besser zu verstehen und Lösungsvorschläge zu erarbeiten. Diese Webseiten bieten aktuelle Informationen zu unseren Aktivitäten und zu den verschiedenen, auch interdisziplinären, Projekten, die wir hier durchführen.

Titel: Social influence motivates public commitments to cooperate



Pledges are commonly used to signal an actor’s intention to act socially desirable, e.g. to cooperate in joint efforts to mitigate climate change. Laboratory experiments testify to their potential effectiveness and previous work has examined under what conditions public commitments promote subsequent trust and cooperation. In this study, I postulate that conformity is an important determinant for the effectiveness of pledges that has been overlooked so far. In specific, I examine what role social influence plays in the decision to pledge. In a public good game, subjects can make prior play a pledge to contribute to the public good in the socially optimal way. Across treatment conditions, I vary the way in which the pledges are elicited. In this way, the degree of social influence on pledge-making is manipulated and its impact can be examined. I find that when individuals are aware that the majority of other subjects decided to pledge, they are likely to conform and also make the pledge. The emergence of such a critical mass can be stimulated when the elicitation of pledges is based on previous contribution behavior. Overall, this commitment nudge is effective. Both socially-oriented and previously not socially-oriented subjects modify their behavior after the pledge.


Everyone interested is welcome to attend.
