This article examines the effect of the Affordable Care Act (ACA) dependent coverage mandate on health insurance and labor supply. The author applies three research designs—difference-in-differences, regression discontinuity, and regression kink designs—and conducts extensive robustness checks and falsification tests, along with a formal test for the location of discontinuity and kink. The author finds no discernible evidence of the labor supply impact of the ACA dependent coverage mandate during the first three years after its implementation (2011–2013), despite its substantial impact on health insurance coverage for the eligible young adults. The author attributes this finding to the fact that until 2014, grandfathered plans were not required to provide dependent coverage to those young adult workers who obtained insurance through their own employer.

本文研究了《平价医疗法案》（ACA）的相关承保范围对健康保险和劳动力供应的影响。作者应用了三种研究设计-差异中的差异，回归不连续性和回归纽结设计-并进行了广泛的鲁棒性检查和伪造测试，以及对不连续和纽结位置的正式测试。作者发现，尽管执行ACA依赖医疗保险计划的最初三年（2011-2013年）对符合条件的年轻人的健康保险承保范围有重大影响，但没有明显的证据表明该计划对劳动力提供的影响。作者将此发现归因于以下事实：直到2014年，
