I am an economist studying how government policy shapes private decisions in health care markets — insurance design, provider pricing and consolidation, pharmaceutical markets, and the intermediaries sitting in between.

Portrait of Anthony T. Lo Sasso

Anthony T. Lo Sasso is the Robert F. and Sylvia T. Wagner Professor of Public Affairs in the La Follette School of Public Affairs at the University of Wisconsin, Madison. He is an economist and health policy scholar whose research focuses on the organization, regulation, and performance of U.S. health-care markets. His work examines health insurance design, provider pricing and consolidation, pharmaceutical markets, and the role of institutions and intermediaries in shaping costs, access, and welfare. He uses applied microeconomic theory and large administrative datasets to address questions central to health-care spending growth and market performance.

His research has been supported by grants and contracts from federal agencies, foundations, and industry partners, and has appeared in leading economics, health policy, and medical journals. This work has informed policy discussions on hospital price transparency, insurance market design, healthcare labor markets, and payment reform.

In addition to his research, Professor Lo Sasso has played prominent leadership roles in the profession, including serving as Executive Director of the American Society of Health Economists (ASHEcon) and as department chair. He has testified before Congress and other legislative bodies, advised public agencies, and served as an expert on health-care market issues. He is deeply committed to teaching and mentorship, with a particular emphasis on applied data analysis, policy-relevant research, and experiential learning.
