We construct a simple three person trust game with one trustor and two trustees. The trustorhas the possibility to either trust both trustees or none, while the trustees make their decisionseither sequentially or simultaneously, depending on the treatment. When trustees play...

In public good provision, privileged groups enjoy the advantage that some of its membersfind it optimal to supply a positive amount of the public good. However, their inherentasymmetric nature may make the enforcement of cooperative behavior through informalsanctioning harder to accomplish...

In many environments, tournaments can elicit more effort from workers, except perhapswhen workers can sabotage each other. Because it is hard to separate effort, ability andoutput in many real workplace settings, the empirical evidence on the incentive effect oftournaments is thin...

This paper aims to experimentally investigate how individual willingness to pay for a lottery is affected by using a new way of representing of probabilistic ambiguity.

This paper experimentally investigates the interdependence between market competition and endogenously emerging inter-firm collaboration. We restrict attention to arrangements resulting from bilateral collaboration agreements that typically characterize real world applications in which the...

Direct transfers allow heirs to freely use what has been passed on to them. Bequeathers who do not trust their descendants to make proper use of the fortune may prefer investing it in a safe foundation, thereby limiting their descendants’ autonomy. In our study we compare experimentally these...
