Estimating Heterogeneous Takeup and Crowd-Out Responses to Existing Medicaid Income Limits and their Nonmarginal Expansions
使用切换概率模型和基于收入上限的医疗补助资格结构，估计非边际医疗补助扩张对儿童参保、私人保险覆盖和挤出效应的影响，并给出易于实施且估计精确的方法。
We use a switching probit model and the income-limit-based structure of Medicaid eligibility for children to estimate treatment effects of nonmarginal Medicaid expansions on Medicaid takeup, private insurance coverage, and crowd-out, as well as crowd-out for those eligible for Medicaid under rules already in place. Many of these estimates are not found in existing work on public insurance and cannot be calculated with the linear probability model used by previous work in this literature. We provide an estimation approach that is straightforward to implement yet yields precise treatment effects.
