Mario Macis is an associate professor with expertise in the areas of prosocial behavior, morally controversial transactions, global health, experimental economics, development economics, and labor economics. He is also an affiliate faculty at the Berman Institute of Bioethics, associate faculty at the Armstrong Institute for Patient Safety and Quality at Hopkins Medicine, faculty research fellow in the National Bureau of Economic Research (NBER), and research fellow at the Institute for the Study of Labor.

Macis has been a consultant for the World Bank, the International Labor Organization, the National Marrow Donor Program, and the United Nations Development Programme.

His most recent research found that most Americans favor compensation for kidney donations if it leads to more saved lives. Paying people to donate organs is illegal in the United States and in most of the recent of the world. Macis's research sought to provide evidence that policymakers might use when considering whether donor-compensation initiatives might gain broad public acceptance.

He has also briefed Congress on research detailing how to use incentives and behavioral prompts to motivate people to get tested for HIV.
