中文摘要
本文研究团队成员过去的合作是否会创造团队专用性人力资本并影响当前团队绩效。利用两项心脏手术的 Medicare 行政理赔数据，我发现，实施手术的医生（“手术医生”）与在患者因该手术住院期间提供照护的医生（“内科医生”）之间的共同工作经历降低了患者死亡率。手术医生—内科医生共同工作经历增加一个标准差，导致患者 30 天死亡率降低 10–14 百分比。患者的医疗资源使用量也随共同工作经历而下降，即便生存率有所改善。（JEL I10, J24, M12, M54）
Abstract
This paper studies whether team members’ past collaboration creates team-specific human capital and influences current team performance. Using administrative Medicare claims for two heart procedures, I find that shared work experience between the doctor who performs the procedure (“proceduralist”) and the doctors who provide care to the patient during the hospital stay for the procedure (“physicians”) reduces patient mortality rates. A one standard deviation increase in proceduralist-physician shared work experience leads to a 10–14 percent reduction in patient 30-day mortality. Patient medical resource use also declines with shared work experience, even as survival improves. (JEL I10, J24, M12, M54)
