摘要：In an inuential study, Mas and Moretti (2009) nd that \worker e ortis positively related to the productivity of workers who see him, but notworkers who do not see him". They interpret this as evidence that so-cial pressure can reduce free riding. In this paper we report an attempt toreproduce the ndings of Mas and Moretti in a lab experiment. Lab exper-iments have the advantage that they can shut down alternative channelsthrough which workers can inuence the productivity of colleagues whomthey observe. Although we nd evidence of peer e ects in our experiment,we nd no evidence that these were consistently positive in the mannersuggested by Mas and Moretti. Instead, our results imply that peer e ectswere heterogeneous, with some workers reciprocating a fast co-worker butothers taking the opportunity to free ride. This suggests that their ndingsare less generalizable than has been assumed.
