The Affordable Care Act (ACA) is the source of multiple large‐scale health insurance expansions affecting various segments of the US population. Although much has been done to quantify the first‐order effects of these policies, less empirical investigation has been devoted to the effects on the supply‐side of health care. We focus on a well‐known ACA initiative (the young adult dependent coverage mandate) to offer novel evidence on two fronts: the policy's heterogeneous effect across different labor markets and the potential for the policy‐induced shift in payer mix to influence provider treatment decisions. First, we show that the federal mandate's direct effect on young adult private insurance take‐up is strongly mitigated by the Great Recession. Second, we demonstrate that providers do not treat young adults more aggressively when more of them hold private coverage. Policymakers should keep these broader considerations and more diffuse risk protection implications in mind when contemplating changes to the law.

私人承保任务、商业周期和提供者治疗强度

平价医疗法案 (ACA) 是影响美国各阶层人群的多项大规模健康保险扩张的根源。尽管已经做了很多工作来量化这些政策的一阶效应，但很少有实证研究致力于对医疗保健供应方的影响。我们专注于一项著名的 ACA 计划（年轻成人受抚养人保险授权），以在两个方面提供新证据：该政策对不同劳动力市场的异质性影响以及政策引起的付款人组合转变影响提供者治疗决策的潜力. 首先，我们表明，大萧条大大减轻了联邦授权对年轻成人私人保险使用的直接影响。第二，我们证明，当更多的年轻人持有私人保险时，提供者不会更积极地对待年轻人。政策制定者在考虑修改法律时，应牢记这些更广泛的考虑因素和更广泛的风险保护影响。
