This week we are pleased to welcome Joseph Doyle to the KHAS Economics Seminars. Doyle is the Erwin H. Schell Professor of Business and Applied Economics at the MIT Sloan School of Management. He is co-director of the MIT Sloan Initiative for Health Systems Innovation and co-chair of the Health Sector of the Jameel Poverty Action Lab. He studies public economics in the areas of health and child welfare. His research focuses on the effects of foster care and other interventions on children, the returns to health spending, and the effects of health insurance on the quality of care provided to patients and health outcomes. He also conducts randomized controlled experiments on changes in the way health services are delivered, with an emphasis on the social determinants of health.
