Ego-relevance in team production

We study how individuals' effort contribution to a team production task varies depending on whether the task is ego relevant or not. We conduct an experiment to test the effect of ego-relevance when the team production depends on the team's top- or bottom-performer. Ego-relevance is manipulated by calling the Raven IQ Test an "IQ Task'' or a "Pattern Task.'' We find that the effort contributed to the task is affected by ego-relevance and the impact of the team production function on effort contribution is mediated by the teammate’s expected effort contribution. Ego-relevance increases the responsiveness to the teammate's expected effort contributions. Similarly, more responsive behavior is noticeable when the team production depends on the bottom-performer. However, we do not observe interaction-effects between ego-relevance and the team production function that affect effort contributions.
