RT Journal Article SR Electronic T1 Non-binding Peer Review and Effort in Teams: Evidence from a Field Experiment JF Journal of Human Resources JO J Hum Resour FD University of Wisconsin Press SP 0717-8907R2 DO 10.3368/jhr.55.4.0717-8907R2 A1 Behrens, Kristian A1 Chemin, Matthieu YR 2019 UL http://jhr.uwpress.org/content/early/2019/09/10/jhr.55.4.0717-8907R2.abstract AB Individuals tend to free-ride in teams, thus providing inefficiently low effort. 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.
