This study uses data from the National Longitudinal Survey of Youth to track the health coverage of parents in the year before and the year in which their children enroll in Medicaid. Use of such longitudinal data, compared to cross-sectional data, provides more insight into the dynamics of health insurance coverage and expansions in Medicaid. Using these data, we find that approximately 16% of newly enrolled Medicaid children likely had access to private insurance through a parent. Moreover, most of the children enrolling in Medicaid were previously uninsured. We find little substitution of private for public health insurance among families living at or near the federal poverty line.
本研究使用了“全国青年纵向调查”的数据，以追踪父母在其子女加入医疗补助计划之前一年和加入医疗补助计划当年的医保覆盖情况。与横断面数据相比，使用此类纵向数据能更深入地了解医疗保险覆盖情况的动态变化以及医疗补助计划的扩张情况。利用这些数据，我们发现，新加入医疗补助计划的儿童中约有16%可能通过父母获得了私人保险。此外，大多数加入医疗补助计划的儿童此前没有保险。我们发现，生活在联邦贫困线及附近的家庭中，私人医疗保险对公共医疗保险的替代情况很少。
