Successful Leadership and the Growth of Teams Gerald Eisenkopf, Torben Kölpin


Teams with successful leaders attract new members. This growth challenges cooperation and coordination within the team. We deploy an experiment to study the behavioral impact of immigration into such a team. We use a variation of the standard voluntary contribution game that allows for leading-by-example. The experimental treatments vary the team size and some allow for migration between teams. The results show that leaders are sensitive to the size of the team. They increase their contributions significantly when the team size increases, and the other team members follow accordingly. A voting mechanism that restricts access of potential new team members increases per-capita contributions of incumbent members. Moreover, a large share of these incumbents sacrifices economic benefits from new team members in order to prefer the preservation of intra-team cooperation.

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


By conducting a laboratory experiment, we test the hypothesis that not only the actual but even the perceived role in outcome generation plays an important role in decision making. For this purpose, decision-makers could either make an allocation which favors themselves or the other party. Afterwards, they could reduce the own perceived responsi-bility in outcome generation by telling recipients falsely that the allocation was made by a die. We observe indeed that a large share of individuals chooses an unfair allocation which favors themselves, however, they are not standing up for it. Finally, analyses of gender dif-ferences reveal that women are more likely to reduce their perceived role in payoff gener-ation by posting that the die has made the allocation.

Leadership is closely linked to acceptance of responsibility and decision-making for others. This involves that decision-makers may consider the consequences of available options for both, their own welfare and others’. In this context, several experimental studies have investigated gender differences in risky decision-making and suggest that men are more willing to be a decision-maker than women are. In these studies, the choice to decline decision-making power has neither a positive nor a negative consequence for the participant. Real world settings, however, are usually characterized by leadership involving at least some positive monetary outcome. The aim of our studies is to investigate whether women are not only less willing than men to accept leadership responsibility, but whether they are more likely to choose not to be a decision maker even if this choice involves monetary consequences. We conducted a laboratory experiment to analyze gender differences in the willingness-to-accept (WTA) to make risky decision for a group. Pretest results show differences between males and females. Women show a higher WTA than men, furthermore, women are less willing to make the group decision compared to men.
