Although a sizeable literature studies the effect of Medicaid on health, less is known about its effects on education. We use a discontinuity in Medicaid eligibility based on date of birth and administrative school records to study the effects of expanded Medicaid eligibility during middle childhood, between the ages of 8 and 11. We evaluate effects of this Medicaid expansion on outcomes measured a few years later when the children are 12-14 years old. We find that it is associated with a significant increase in the grade that children are in and a reduction in the likelihood that a child is below grade for age. We do not find any evidence for effects on documented disabilities or absences. Our results underscore that Medicaid has important effects on children's human capital.

尽管有大量文献研究了医疗补助对健康的影响，但人们对其医疗教育的影响知之甚少。我们根据出生日期和行政学校的记录，使用了医疗补助资格的不连续性，以研究8岁至11岁的中儿童期医疗补助资格扩展的影响。我们评估了这种医疗补助扩展对几年后测得的结局的影响孩子年龄在12-14岁之间。我们发现，这与孩子所在年级的显着提高以及孩子年龄低于年级的可能性降低有关。我们没有发现任何证据表明有记载的残疾或缺勤。我们的结果强调，医疗补助对儿童的人力资本具有重要影响。
