We analyse an experimental public goods game in which group members can endogenously determine whether they want to supplement a standard voluntary contribution mechanism with the possibility of rewarding or punishing other group members. We find a large and positive effect of endogenous...

Direct democracy with its use of referenda avoids the prototypical principal-agent problems of delegation in indirect democracies, especially since elected representatives are usually not committed by law to keep their promises. Sequential or more complex referenda may, however, result in an...

We present an experimental study on the wasted resources associated with tax evasion. This waste arises from taxpayers and tax authorities, investing costly effort in concealment, respectively detect ion, of tax evasion. We show that (socially inefficient) efforts depend positively on the...

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...

Myopic loss aversion (MLA) has been established as one prominent explanation for the equity premium puzzle. In this paper we address two issues related to the effects of MLA on risky investment decisions. First, we assess the relative impact of feedback frequency and investment flexibility (via...

Even though decision-making in small teams is pervasive in business and in private life, little is known about subjects' preferences with respect to individual and team decision-making and about the consequences of respecting these preferences. We report the results from an experimental...

We examine experimentally two different types of trust: trust in another party’s cooperation and trust in ability. In the cooperation condition, player A sends x ? {0, X} to player B. The amount x is multiplied by c = 3, and B can return y ? {0,3x}. In the ability condition, c depends on B’s...

We study the influence of gender on economic decision making in a two-person bargaining game. By testing hypotheses derived from evolutionary psychology and social role theory, we find that (1) gender per se has no significant effect on behavior, whereas (2) gender pairing systematically affects...
