Mario Macis is Associate Professor at Johns Hopkins University, Carey Business School, where he also serves as the Academic Program Director of the MS in Health Care Management. He is also Associate Faculty at the Armstrong Institute for Patient Safety and Quality at the JHU School of Medicine and Faculty Research Fellow at the National Bureau of Economic Research (NBER).

Mario’s research focuses on incentives, pro-social behavior, morally controversial transactions, ethics and economics, global health and labor economics. He has conducted large-scale randomized controlled trials in partnership with blood banks (including the American Red Cross) to study the interplay between intrinsic motivation and incentives in pro-social behavior. In recent work at the intersection of economics and bioethics, he studies attitudes toward morally controversial economic transactions such as payments for human organs for transplantation. In ongoing work, he is running a field experiment that taps into people’s social networks in India to improve tuberculosis detection.

Mario’s research has received various competitive grants, including grants from the National Science Foundation, the National Institutes of Health and the World Bank’s Strategic Impact Evaluation Fund, and was published in prominent academic outlets, including Science, the American Economic Journal: Economic Policy, the Journal of Health Economics, the Journal of Labor Economics, Management Science and Sociological Science.

Mario received his undergraduate degree in Economics and Social Disciplines from Bocconi University in Milan, and his Ph.D. in Economics from the University of Chicago.
