TY - JOUR T1 - Nonbinding Peer Review and Effort in Teams JF - Journal of Human Resources JO - J Hum Resour SP - 1365 LP - 1399 DO - 10.3368/jhr.55.4.0717-8907R2 VL - 55 IS - 4 AU - Kristian Behrens AU - Matthieu Chemin Y1 - 2020/10/02 UR - http://jhr.uwpress.org/content/55/4/1365.abstract N2 - 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 complete an online survey to review the effort of their peers. These reviews are not linked to any rewards or sanctions, thus making them nonbinding. We find that nonbinding 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 -
