Austin Frakt of Boston University and blogger at The Incidental Economist talks with EconTalk host Russ Roberts about Medicaid and the recent results released from the Oregon Medicaid study, a randomized experiment that looked at individuals with and without access to Medicaid. Recent released results from that study found no significant impact of Medicaid access on basic health measures such as blood pressure and cholesterol levels, but did find reduced financial stress and better mental health. Frakt gives his interpretation of those results and the implications for the Affordable Care Act. The conversation closes with a discussion of the reliability of empirical work in general and how it might or might not affect our positions on social and economic policy.
