To assess the effects of transitions from private to public health insurance by children on out-of-pocket medical expenditures and health insurance premium costs.
Data are drawn from the 1996 and 2001 panels of the Survey of Income and Program Participation. We construct a nationally representative, longitudinal sample of children, ages 0-18, and their families for the period 1998-2003, a period in which states raised public health insurance eligibility rates for children.
We exploit the Survey of Income and Program Participation's longitudinal design to identify children in our sample who transition from private to public health insurance. We then use a bootstrapped instrumental variable approach to estimate the effects of these transitions on out-of-pocket expenditures and health insurance premium costs.
Children who transition from private to public coverage are relatively low-income, are disproportionately likely to live in single-mother households, and are more likely to be Black or of Hispanic origin. Child health status is highly predictive of transitions. We estimate that these transitions provide a cash-equivalent transfer of nearly U.S.$1,500 annually for families in the form of reduced out-of-pocket and health insurance premium costs.
Transitions from private to public health coverage by children can bring important social benefits to vulnerable families. This suggests that instead of being a net societal cost, such transitions may provide an important social benefit.
评估儿童从私人医疗保险向公共医疗保险过渡对自付医疗支出和健康保险费成本的影响。
数据来自收入和参与计划调查的 1996 年和 2001 年小组。我们构建了一个具有全国代表性的、1998-2003 年期间 0-18 岁儿童及其家庭的纵向样本,在此期间各州提高了儿童公共医疗保险的资格标准。
我们利用收入和参与计划调查的纵向设计来确定我们样本中从私人医疗保险向公共医疗保险过渡的儿童。然后,我们使用bootstrap 工具变量方法来估计这些过渡对自付支出和健康保险费成本的影响。
从私人保险转为公共保险的儿童收入相对较低,不成比例地居住在单亲家庭中,更有可能是黑人或西班牙裔。儿童健康状况高度预示着过渡。我们估计,这些过渡以减少自付和健康保险费成本的形式,每年为家庭提供近 1500 美元的现金等价物转移。
儿童从私人医疗保险向公共医疗保险的过渡可以为弱势家庭带来重要的社会效益。这表明,这些过渡可能提供了重要的社会效益,而不是社会的净成本。
