Team-Specific Human Capital and Team Performance: Evidence from Doctors
研究医生之间的过往合作经验是否构成团队特定人力资本，并影响当前团队绩效。发现手术医生与住院医生共享工作经历越多，患者30天死亡率越低，医疗资源使用也减少。
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.
