Effort Peer Effects in Team Production: Evidence from Professional Football
利用以色列职业足球联赛的高频数据，研究高技能团队任务中球员努力的同伴效应，发现显著的正向溢出效应，且行为因素可能是重要机制。
We exploit a unique data set from the Israeli Professional Football Leagues that provides high-frequency direct measures of players’ effort to estimate effort peer effects in a high-skill collaborative team task. Using two complementary identification strategies, we find robust evidence of substantial positive peer effects. Our findings highlight that effort spillovers play an important role in team production and that even a change in just one worker’s effort can substantially influence team effort and thus performance. Moreover, we present suggestive evidence that behavioral considerations are a relevant mechanism for creating peer effects even in highly skilled teams of workers.
