Anticipated verbal feedback in a dictator game has been shown to induce altruistic behavior. However, in the ultimatum game which, apart from generosity, entails a strategic component since a proposer may (rightly) fear that the responder will reject a low offer, it remains an open question...

Numerous studies suggest that communication may be a universal means to mitigate collective action problems. In this study, we challenge this view and show that the communication structure crucially determines whether communication mitigates or intensifies the problem of collective action. We...

Numerous studies suggest that communication may be a universal means to mitigate collective action problems. In this study, we challenge this view and show that the communication structure crucially determines whether communication mitigates or intensifies rent-seeking for pure public goods. We...

In this contribution, we investigate the effects of observation-only and observation with feedback from a third-party in a one-shot dictator game (DG). In addition to a baseline condition (DG), a third-party anonymous subject was introduced who either silently observed or observed and got to...

This paper experimentally investigates free-riding behavior on communication cost in a coordination game and finds strong indications of such free-riding. Firstly, the subjects tend to wait for others to send a message when communication is costly, which does not happen when communication is...

We investigate experimentally the effects of information about native/immigrant identity, and the ability to communicate a self-chosen personal characteristic towards the rival on conflict behavior. In a two-player individual contest with British and Immigrant subjects in the UK we find that...

Communication is a well-known tool to promote cooperation and pro-social behavior. In this study, we examine whether minimal communication in form of public consent with a pre-defined cooperation statement is sufficient to strengthen cooperation in groups. Within the controlled environment of a...

This experimental study explores how communication influences efficiency, trust and trustworthiness in a small group when one member is left out of communication. To study this problem, we introduce a novel three-player trust game where player 1 can send any portion of his endowment to player 2....

This paper explores experimentally the effects of costly communication possibilities in market entry games. It is shown that these effects depend on whether entry costs are symmetric or asymmetric. In the former, but not the latter case, communication possibilities increase coordination success...
