This Monte-Carlo study investigates sensitivity of the Wilcoxon signed rank test to certainassumption violations in small samples. Emphasis is put on within-sample-dependence,between-sample dependence, and the presence of ties. Our results show that both assumptionviolations induce severe size...

The winner's curse is a well-known deviation from rational self-interest in decision-making under asymmetric information. Yet, most prominent explanations for the curse have experimentally been ruled out so far. In particular, the curse did neither seem to emanate from a lack of experience with...

Traditionally, giving in dictator games was assumed to signal preferences over others' payoffs. To date, several studies find that dictator game giving breaks down under conditions designed to increase dictators' anonymity or if an option to take money obscures the purpose of the task. Giving is...

We study individuals who can nudge themselves out of, or opt into a set of rules which either allows them to spy on an opponent, or to sabotage an opponent, or to fabricate payoff-relevant information on the opponent s moves. In an experiment, we observe significant altruism under rules which...

We study individuals who can choose how to compete with an opponent for one nonzero payoff. They can either nudge themselves into a fair set of rules where they have the same information and actions as their opponent, or into unfair rules where they spy, sabotage or fabricate their opponent's...

Theoretically and experimentally, we generalize the analysis of acquiring a company (Samuelson and Bazerman 1985) by allowing for competition of both, buyers and sellers. Naivety of both is related to the idea that higher prices exclude worse qualities. While competition of naive buyers...

Most research in economics models agents somehow motivated by outcomes. Here, we model agents motivated by procedures instead, where procedures are defined independently of an outcome. To that end, we design procedures which yield the same expected outcomes or carry the same information on...

Games of imperfect information distribute information unevenly amongst parties. Recently, parties have been claimed to hold preferences purely over such procedural aspects. Here, I explore the impact purely procedural preferences exert if agents are without influence on the procedure itself. I...
