Abstract

This dissertation is a collection of three essays that study the interconnection between the Affordable Care Act (ACA) Marketplace plans and disability claiming and the effects of the COVID-19 pandemic on prescription drug utilization for anxiety and depression among Medicaid enrollees. The first essay examines the effects of the COVID-19 pandemic on prescription drug use for anxiety and depression among Medicaid enrollees, using Medicaid State Drug Utilization Data. The findings suggest that the COVID-19 pandemic increased the use of prescription drugs for anxiety and depression relative to prescription drugs use for all conditions, but decreased prescription drugs use for anxiety and depression per Medicaid enrollee. The second essay studies the relationship between the pricing of ACA Marketplace plans and disability claiming through Supplemental Security Income (SSI) and SSI for Children programs. The results document that certain subgroup populations are affected by changes in the premium of a 30-year-old-with-two-children health plan. Individuals living in states or GRAs with higher unemployment rates, poverty ratios, high school graduation rates, and work limitation rates become less likely to apply for SSI programs to get health insurance if the premium of a 30-year-old-with-two-children health plan increases. Populations living in GRAs where there are higher percentages of non-Hispanic whites or individuals reporting difficulties with daily tasks or work limitations, meanwhile, become more likely to apply. The third essay decomposes the effects of prevalence of pre-existing mental health conditions, state-level demographics, COVID-19 policies, and other state-level healthcare policies in explaining the changes in anxiety and depression prescription during the COVID-19 pandemic. It finds heterogeneous effects due to specific factors, such as the pre-existing prevalence of mental health conditions, state-level demographics (race and ethnicity), COVID-19 policies (lockdown, mask, and school closure mandates), and state-level healthcare policies (Medicaid expansion, and limited PDMP use mandate,) on use of prescription drugs for anxiety and depression during the pandemic.
