Welcome to my webpage.

I am an associate professor of economics at Johns Hopkins University, Carey Business School, where I am also the Academic Program Director of the MS in Health Care Management.  I received my PhD in Economics at the University of Chicago, and I hold a BA in Economic and Social Disciplines (DES) from Bocconi University
I am also Associate Faculty in the Armstrong Institute at Johns Hopkins Medicine, Faculty Research Fellow at the National Bureau of Economic Research (NBER), and Research Fellow at the Institute for the Study of Labor (IZA)

My research focuses on incentives, pro-social behavior, morally controversial transactions, global health and labor economics.

I recently co-edited (with Joan Costa-Font) a book on Social Economics, Published by MIT Press.

I organized a Symposium and Workshop on The Ethics and Economics of Compensation for Body Parts, with Jeffrey Kahn of the Berman Institute of Bioethics.
