Health Policy & Economics

Abstract shapes with healthcare icons

The Division of Health Policy and Economics studies the U.S. healthcare system with the goal of making discoveries and recommendations for improvement.  We study the effects of public and private policies on provider organizations and the value of care delivered.  We focus on incentives, unintended consequences, and the impact of policies and organizational processes on socioeconomic and racial/ethnic disparities.  Our current areas of investigation are broad and include telehealth, private equity, physician management companies, horizontal and vertical consolidation of provider organizations, physician burnout and professionalism, physician turnover, the use of artificial intelligence in medical care, MIPS, alternative payment models, biosimilars, advance care planning, mental health and substance use disorder care, socioeconomic determinants of health, Medicaid, and the healthcare safety net.
