The Affordable Care Act (ACA) expanded the availability of public health insurance, decreasing the relative benefit of participating in disability programs but also lowering the cost of exiting the labor market to apply for disability benefits. In this paper, we explore the impact of expanded access to Medicaid through the ACA on applications to the Supplemental Security Income (SSI) and Social Security Disability Insurance (SSDI) programs. Using the fact that the Supreme Court decision of June 2012 made the Medicaid expansion optional for the states, we compare changes in county-level SSI and SSDI caseloads in contiguous county pairs across a state border. We find no significant effects of the Medicaid expansion on applications or awards to either SSI or SSDI, and can reject economically meaningful impacts of Medicaid expansions on applications to disability programs.

ACA医疗补助扩展对残疾计划应用程序的影响

《平价医疗法案》（ACA）扩大了公共健康保险的适用范围，降低了参加残疾计划的相对利益，但同时也降低了退出劳动力市场以申请残疾津贴的成本。在本文中，我们探讨了通过ACA扩大对Medicaid的访问对补充安全收入（SSI）和社会安全残疾保险（SSDI）计划的应用程序的影响。利用最高法院2012年6月的裁决使各州的医疗补助计划扩展成为可选项，我们比较了跨州边界的连续县对中县级SSI和SSDI案件数量的变化。我们发现，医疗补助计划的扩展不会对SSI或SSDI的申请或授予产生重大影响，
