We implement a system of confidential peer review in a randomly selected set of teams, whereby teammates fill an online survey to review the effort of their peers. These reviews are not linked to any rewards or sanctions, thus making them non-binding. We find that non-binding peer reviews increase effort and team productivity and do not decrease worker morale. The effects are stronger for low-ability individuals in low-ability teams where the traditional forces of peer effects may be absent. ER -
