While politically attractive in order to generate tax revenues, the effects of a financial transaction tax (FTT) are scientifically disputed, not the least because seemingly small details of its implementation may matter a lot. In this paper, we provide experimental evidence on the different...

Credence goods markets suffer from inefficiencies caused by superior information of sellers about the surplus-maximizing quality. While standard theory predicts that equal mark-up prices solve the credence goods problem if customers can verify the quality received, experimental evidence...

We present an overlapping-generations model with two interacting teams, where young team members earn an income, whereas old team members depend on either intrateam transfers from young members (voluntary solidarity) or tax-financed transfers (compulsory solidarity). We derive the individually...

We present a model where compensation within a workteam is determined endogenously by the use of a rank-order tournament. Team members compete in their efforts for the right to propose the distribution of a prize within the team. The implementation of a proposal requires the approval of other...

We examine the degree of trust and reciprocity in an experimental trust game with 662 participants from six different age groups, ranging from 8 year old primary school children to retired persons in their late sixties. Although both trust and reciprocity have been identified as fundamental...

Leadership is important for the well-functioning of organizations. We examine the effects of leadership on contributions in public goods experiments. Leadership by example is implemented by letting one group member contribute to the public good before followers do. Such leadership increases...

In our data analysis we focus on (1) the influence of age, gender, profession and the medium chosen for participation on bargaining behavior and on (2) the external...

We study the effects of leadership on the private provision of a public good when group members are heterogeneously endowed. Leadership is implemented as a sequential public goods game where one group member contributes first and all the others follow. Our results show that the presence of a...
