This paper reports the results of a lab experiment designed to study the role of observability for peer effects in the setting of a simple production task. In our experiment, participants in the role of workers engage in a team real-effort task. We vary whether they can observe, or be observed by, one of their co-workers. In contrast to earlier findings from the field, we find no evidence that low-productivity workers perform better when they are observed by high-productivity co-workers. Instead, our results imply that peer effects in our experiment are heterogeneous, with some workers reciprocating a high-productivity co-worker but others taking the opportunity to free ride.
本文报告了一项实验室实验的结果，该实验旨在研究在简单生产任务环境中可观察性对同伴效应的作用。在我们的实验中，扮演工人角色的参与者参与一项团队实际工作任务。我们改变他们是否能够观察到或被其一名同事观察到的情况。与该领域早期的研究结果相反，我们没有发现证据表明低生产率工人在被高生产率同事观察时表现会更好。相反，我们的结果表明，我们实验中的同伴效应是异质的，一些工人会回应高生产率同事，但另一些人则趁机搭便车。
