The labor market impact of upper extremity musculoskeletal injuries that result in permanent disability was estimated using data from the State of California. Administrative data on disability evaluations and resulting ratings was matched to data on the earnings of over 7000 injured workers. Using these data, labor market experience pre- and postinjury was tracked. Each injured worker was matched to a set of control workers who worked at the same firm, had the same tenure at the firm, and earned the same income at the time of injury. By comparing the injured and uninjured workers, lost earnings and the impact of injury on return to work was estimated. Evidence of considerable lost earnings resulting from injury was found. The results are compared to "disability ratings" that are used to set compensation under California's workers' compensation program. The disability rating was also found to predict poorly differences across upper extremity injuries in losses. In particular, those with shoulder injuries have larger losses than those with elbow or wrist injuries, despite receiving the same disability ratings.
利用加利福尼亚州的数据，对导致永久性残疾的上肢肌肉骨骼损伤的劳动力市场影响进行了估计。关于残疾评估及最终评级的行政数据与7000多名受伤工人的收入数据进行了匹配。利用这些数据，追踪了受伤前后的劳动力市场经历。每名受伤工人都与一组对照工人进行匹配，这些对照工人在同一家公司工作，在公司的任期相同，且在受伤时收入相同。通过比较受伤工人和未受伤工人，估计了收入损失以及受伤对重返工作岗位的影响。发现了因受伤导致大量收入损失的证据。将结果与用于加利福尼亚州工人赔偿计划下设定赔偿的“残疾评级”进行了比较。还发现残疾评级对上肢损伤损失的差异预测能力较差。特别是，肩部受伤的人比肘部或腕部受伤的人损失更大，尽管他们获得的残疾评级相同。
