This paper examines how income levels affected the substitution of public health insurance for private health coverage under expansions of Illinois' State Children's Health Insurance Program (SCHIP). Building on a technique developed by Abadie and Gardeazabal (2003), I estimate that among children whose family incomes are between 200% and 300% of the federal poverty level (FPL), 35% of those covered by SCHIP would have retained private coverage in the absence of SCHIP. Significant substitution also appears between 300% and 400% FPL, but surprisingly I find evidence that the introduction of SCHIP caused an increase in private health insurance coverage for those with family incomes between 400% and 500% FPL.
本文探讨了在伊利诺伊州儿童健康保险计划（SCHIP）扩张的情况下，收入水平如何影响公共医疗保险对私人健康保险覆盖范围的替代。基于阿巴迪和加德亚扎巴尔（2003年）开发的一种技术，我估计，在家庭收入处于联邦贫困线（FPL）200%至300%之间的儿童中，如果没有SCHIP，35%参加SCHIP的儿童原本会保留私人保险。在FPL的300%至400%之间也出现了显著的替代，但令人惊讶的是，我发现有证据表明，SCHIP的引入导致家庭收入在FPL的400%至500%之间的人群的私人医疗保险覆盖范围有所增加。
