Abstract

This study examines how the Medicaid expansion has affected health coverage, medical care utilization, financial well-being, and self-reported health. This study distinguishes itself from prior literature in that it also examines how the effect of the Medicaid expansion depends upon state cost-sharing requirements. Further, the study leverages a natural experimental design based on the introduction of a policy intervention (i.e. the Medicaid expansion in 2014). A difference-in-difference regression model is first used to compare states that did and did not expand Medicaid. A second difference-in-difference regression model is then used to compare states that did not expand Medicaid, states that did expand Medicaid with cost-sharing requirements, and states that did expand Medicaid without cost-sharing requirements. Results indicate that the Medicaid expansion is associated with improvements in coverage, utilization, and financial well-being. However, it is also associated with a worsening in self-reported health outcomes. Furthermore, states that expanded Medicaid without cost-sharing requirements outperformed states that also expanded Medicaid but with cost-sharing requirements in all outcomes including self-reported health outcomes.
