Career Choice and Cooperation in a Prosocial Team Task

Does the type of career chosen by partners affect willingness to cooperate in a pro-social team activity? Using a lab-on-the-field experiment, this paper shows that agents draw inferences on their partners' motivation from the career path chosen by them, and increase their effort in team production when their partner's career choice reveals higher motivation. In an experiment conducted at the LSE in 2017, subjects were paired up in teams and asked to fill envelopes for an LGBTI charity. Team production was structured in such a way that teammates' effort would be perfectly complementary. Before the task, subjects were given a chance to obtain the full compensation or to volunteer part of it. Subjects who were partnered with a volunteer produced significantly more envelopes than subjects partnered up with a non-volunteer. The effect was highest on the higher quantiles of the distribution of effort and was concentrated among the most driven by the cause. Mediation analysis suggests that the effect is mediated by expectations about one’s partner’s effort. These findings suggest that the composition of teams is an important factor of team production when there are complementarities of production and there is scope for pro-social motivation.
