My research studies the equity and efficiency of government interventions in health insurance and healthcare markets. I have examined different types of interventions: public funding of privately-provided health insurance programs, the regulation of premiums and the scope of coverage in health insurance,  the direct public procurement of healthcare, and the provision of information. I use a broad toolbox of empirical  methods and a variety of administrative data and contexts, including Medicare, Medicaid, ACA Marketplaces, and public insurance programs in the EU, with the aim of understanding and quantifying the economic mechanisms that drive the outcomes of interventions.
