Heidi Williams

Heidi Williams received an A.B. (2003) from Dartmouth College, an M.Sc. (2004) from the University of Oxford, and a Ph.D (2010) from Harvard University. She has been affiliated with the Massachusetts Institute of Technology since 2011 and is currently the Class of 1957 Career Development Assistant Professor in the Department of Economics. She is also a faculty research fellow (since 2010) at the National Bureau of Economic Research. Heidi Williams is an economist unraveling the causes and consequences of innovation in health care markets. Williams combines finely grained empirical observations and custom-designed data collection methods to build entirely new datasets about technological changes in health care. In addition, her creative methods for determining causal inference, and keen understanding of regulatory law, biological science, and medical research, have allowed her to trace the interplay among institutions, market behavior, and public policy–relevant outcomes.
