This paper provides micro evidence of labor mobility inside business groups. We show that worker flows between firms in the same group are stronger than with unaffiliated firms. Moreover, the reallocation of top workers between group firms is more sensitive to international shocks. Top workers that move within the group in response to shocks reach higher positions and earn higher wages. We find suggestive evidence that productivity increases when firms receive same-group top workers. Our results are consistent with the hypothesis that, in response to changing opportunities, joint ownership eases the redeployment of workers endowed with general management skills.

本文提供了企业集团内部劳动力流动的微观证据。我们表明，同一组中公司之间的工人流动比非附属公司强。此外，集团公司之间顶级工人的重新分配对国际冲击更为敏感。为应对冲击而在集团内流动的顶级工人会获得更高的职位并获得更高的工资。我们发现有启发性的证据表明，当公司接收同一群体的顶级工人时，生产率会提高。我们的结果与假设一致，即为了应对不断变化的机会，共同所有权可以简化具有一般管理技能的工人的重新部署。
