Grace McCormack

Biography

My work largely focuses on understanding competitive forces in insurance markets. Many of my current projects focus on provider networks in Medicare Advantage. In ongoing projects, I characterize enrollee valuation of primary care providers in Medicare Advantage, study how adverse selection incentives impact mental health network formation, and evaluate regulatory determinants of hospital network composition. I also have ongoing work studying employer preferences in the employer-sponsored insurance market. My past work touches on topics in Medicaid and the ACA exchanges.
