Mario Macis is full Professor at Johns Hopkins University, Carey Business School. He is also Affiliate Faculty at the JHU Berman Institute of Bioethics and Research Associate at the National Bureau of Economic Research (NBER).

Mario is an applied economist and his work focuses on how economic incentives interact with psychological factors and social norms to drive individual behavior and policy-relevant outcomes. His research largely falls into one of three related areas:
- The role of economic incentives in shaping prosocial behavior, with a focus on blood donation.
- Understanding individual preferences for policy options to regulate morally controversial exchanges, particularly payments to organ donors.
- Using behavioral interventions and incentives to induce behavioral change in health-related contexts, and to shed light on the mechanisms underlying that change.

He is also interested in various topics in labor, health, and development economics, including some determinants of wage dispersion in firms (globalization and discrimination), and the determinants and effects of the adoption of managerial practices in health care organizations in low-income countries.

Mario's studies were funded by several funding agencies, including the NSF and the NIH. His work was published in prominent academic outlets including the American Economic Review, Science, the Economic Journal, the American Economic Journal: Economic Policy, the Journal of Health Economics, the Journal of Labor Economics, the Journal of Development Economics, and Management Science.

Mario received his undergraduate degree in Economics and Social Disciplines (DES) from Bocconi University in Milan, and his Ph.D. in Economics from the University of Chicago. Prior to joining Carey, he was Assistant Professor of Business Economics and Public Policy at the University of Michigan, Ross School of Business. He has been a consultant for for the World Bank, the International Labor Organization, the National Marrow Donor Program, and the United Nations Development Programme.

He joined IZA as a Research Fellow in September 2008.
