Cooperation and Attrition in Online-Experiments Gerald Eisenkopf, Torben Kölpin


This paper studies the impact of task motivation on attrition in online-experiments. We put our participants in groups of four. At the beginning of any period, each group member must complete a costly and tedious work task. The task costs increase with each period. A completed task results in an individual payoff. Participants can either keep the payoff, or they can choose to cooperate. The decision of cooperation imposed net private costs on the cooperator but generated a benefit for the fellow group members. Participants could leave the experiment at any stage of the experiment. Leaving participants still benefit if other group members choose to cooperate. In one treatment, the members observe the decision of a randomly chosen leader when they decide themselves, while all members decide simultaneously in the other treatment.  In the Control-Treatment there was no cooperation opportunity. In general, we observe that participants leave at a later stage if group members cooperate successfully. However, a lack of cooperation leads to participants losing interest in the task and dropping out.

Leadership and Cooperation in growing teams Gerald Eisenkopf, Torben Kölpin


The admission of new members challenges cooperation and coordination within successful teams. To study the behavioral impact of such immigration, we divide our experimental participants into two teams. In each team the members contribute to a club good, and all participants can compare contributions and payoffs across teams. In one of the two teams the random allocation of a leader enhances the cooperation among its members. The experimental treatments either vary the leader’s team size exogenously or allow for migration between the teams. By design, new team members do not impose any direct monetary costs to the incumbents. We observe that leaders show more courage with increasing team size, fostering both cooperation and immigration. However, the leader’s impact on the contribution of followers decreases in team size. A voting mechanism that restricts immigration increases per-capita contributions. In this case incumbent team members sacrifice economic benefits from potential entrants in order to maintain intra-team cooperation.

It wasn't me - unfair decision making and not standing up for it Robert Gillenkirch, Torben Kölpin, Vanessa Mertins


Managers must regularly take unpleasant decisions which affect others.  In such situations, individuals are known to shift blame. We use two variants of the dictator game experiment: in the first setting, decision-makers choose the allocation and can lie about their responsibility for the resulting token distribution. In the second game, the allocation is decided by rolling a die while dictators can choose to misrepresent the result.  Our results confirm that dictators who favor themselves more also lie more often to conceal their responsibility. This effect is stronger for women than men, although women generally treat recipients more generously.
