"Medicaid Coverage for Births after ACA’s Dependent Coverage”, with Yaa Akosa Antwi, Aaron Carroll, and Kosali Simon,
Research letter, New England Journal of Medicine, Jan 13, 2016
Abstract: This study provides evidence of the impact of health insurance on fertility decisions in the context of young adults. The Affordable Care Act young adult provision has been shown to expand private health insurance coverage for the intended age group. Having health insurance improves access to family planning services and could reduce unintended pregnancy. The provision also induced private insurance to substitute Medicaid coverage during pregnancy. Using birth certificate data and a difference-in-differences study design, we examined the impact of the provision on fertility rates, prenatal care and birth outcomes by comparing the targeted group to slightly older adults. We found that the young adult provision reduced fertility rates by about 5% in the first 3 years following the policy change and increased the share of children born to unmarried, minority, or less educated mothers. The evidence also suggested that the provision encouraged earlier initiation of prenatal care and reduced maternal smoking and pregnancy complications. However, birth outcomes seemed to be non-responsive to the provision.
Abstract: Ex ante moral hazard refers to the situation that people make inefficiently low investments in self-protective activities because of insurance coverage. However, in the context of health insurance, ex ante moral hazard is argued to be less of a concern due to utility loss from the uncompensated health outcome. The small existing empirical researches also find mixed evidence. This paper uses a regression discontinuity design to explore the effect of losing health insurance around age 19 on young adults’ health behaviors including smoking, drinking and exercising. The discontinuity of health insurance comes from young adults aging out of Medicaid coverage and private insurance dependent coverage. I use data from National Health Interview Survey (NHIS) from 1997 to 2012 to construct the sample. The analyses find evidence supporting the existence of ex ante moral hazard that the uninsurance rate increased by 4.04% (19.1 percentage increase to age 18 mean) at age 19 results in a reduction in smoking rate by 2.69% (15.2 percentage decrease).
“医疗保险的戒烟辅助与戒烟产品的使用” (with Kosali Simon)
Abstract: To examine the causal impact of Medicaid smoking cessation coverage on prescriptions for smoking deterrents. We examine state Medicaid coverage for four types of cessation interventions: nicotine replacement therapies (NRT), varenicline, bupropion and behavioral counseling. We utilized a ‘differences in differences’ technique with state and year fixed effects to assess the effect of Medicaid smoking cessation coverage on use of prescription cessation purchases. We find that having a complete deterrents coverage significantly increases the use of deterrents by 43.9%, mainly by encouraging the use of NRT and varenicline. Adding coverage for behavioral counseling beyond the complete coverage of deterrents has little impact on deterrents use.
