This study contributes to human capital resource literature by providing a robust and theoretically grounded examination of the relationship between unit‐level tenure and performance. We (a) posit and test the notion of a positive nonlinear relationship between aggregate tenure and labor productivity and (b) expand the current conceptualizations of unit‐level tenure to examine the joint and interactive effects of aggregate tenure and tenure dispersion on labor productivity. Utilizing time‐lagged data collected from a field‐sample of 514 college bookstores, we report findings suggesting that unit‐level aggregate tenure has a positive but nonlinear relationship with labor productivity such that increasing tenure beyond an optimum point produces diminishing returns. These results are replicated in a second study conducted with a cross‐sectional sample of 727 service organizations in the United States. Further, our findings indicate that tenure dispersion is negatively related to labor productivity but positively moderates the relationship between aggregated tenure and labor productivity.

任期过多？单位制任期和劳动生产率的非线性影响和适度影响

这项研究通过对单位级别的任期与绩效之间的关系进行有力且理论基础的考察，为人力资本资源文献做出了贡献。我们（a）提出并检验了总使用权与劳动生产率之间的正非线性关系的概念，并且（b）扩展了当前的单位层级使用权的概念，以检验总使用权和使用权分散对劳动生产率的联合和互动影响。我们利用从514家高校书店的田间样本中收集的时间滞后数据，报告发现表明，单位级别的总保有权与劳动生产率具有正相关但呈非线性关系，因此，使保有权增加超过最佳点会产生收益递减的现象。这些结果在第二项研究中得到了重复，该研究是对美国727个服务组织的横断面样本进行的。此外，我们的研究结果表明，权属分散与劳动生产率负相关，但正缓和了总权与劳动生产率之间的关系。
