我通过使用断点回归设计来估计医疗补助资格对使用率、私人健康保险覆盖范围、医疗保健利用率和儿童健康的因果影响。与标准回归不连续性设计相反，识别利用了因各州收入资格规则的变化而产生的多个阈值。使用收入动态小组研究及其儿童发展研究补充的数据，我发现医疗补助资格平均增加了 1013 个百分点，在收入资格门槛较低的情况下上升到 2429 个百分点。存在与占用率相同程度的显着挤出效应。医疗补助资格使预防性医疗保健的使用率提高了 1114 个百分点，但仅限于低收入人群。最后，我发现医疗补助资格在短期和中期对健康结果没有重大影响。版权所有 (C) 2012 约翰·威利父子有限公司
I estimate the causal impact of Medicaid eligibility on take up, private health insurance coverage, healthcare utilization, and children's health by using a regression discontinuity design. In contrast to a standard regression discontinuity design, identification exploits multiple thresholds that arise from variation across states in income eligibility rules. Using data from the Panel Study of Income Dynamics and its Child Development Study supplement, I find that Medicaid eligibility increases take up by 1013 percentage points on average, rising to 2429 percentage points at lower income eligibility thresholds. There are significant crowding out effects of the same magnitude as those on take up rates. Medicaid eligibility increases the use of preventive health care by 1114 percentage points but only at low income thresholds. Finally, I find that Medicaid eligibility has no significant effects on health outcomes in the short and medium run. Copyright (C) 2012 John Wiley & Sons, Ltd.
