简介 |
<p>The implementation of the Affordable Care Act (ACA) has led to significant increases in health insurance enrollment among low- and moderate-income populations, particularly in disadvantaged areas. Exploiting geographic variations in ACA-induced enrollment changes, we use a dyadic Difference-in-Differences regression model with continuous treatment to estimate whether, and to what extent, health insurance enrollment gains, particularly private insurance and Medicaid, affect physicians' location choices and, consequently, reshape spatial disparities in physician access. We find that an increase in private insurance enrollment in a location attracts physicians through relocation, whereas an increase in Medicaid enrollment tends to deter them, particularly among those with greater experience or from top-tier medical programs. The discouraging effect of Medicaid is largely due to its low reimbursement rates, while the appeal of private insurance is driven by physicians' desire to serve a broader patient market. In sum, our simulations, based on reduced-form estimates and a discrete choice model, suggest that ACA insurance expansions may have inadvertently exacerbated disparities in physician access in disadvantaged areas. Regarding other medical providers, we find that the ACA health insurance expansion similarly influences the geographic distribution of physician assistants and nurses, but has no significant effect on medical institutions such as physician organizations, hospitals, and health centers.</p> |
