We study how help can be fostered by means of a team bonus in the presence of rank-order tournaments. In a simple model … we combine elements of relative rewards and a team bonus and study their effect on effort, help and sabotage. Quite … intuitively the theoretical analysis suggests that team members help less as relative rewards increase. This problem is mitigated …

an experiment with piece-rate incentives we find that the comparative static and the point predictions on effort … provision are remarkably accurate. We also present experimental findings from three classic experiments, namely, team production … induced values, which is useful for theory-testing purposes as well as for applications. …
