Ufuk Akcigit

Ufuk Akcigit is an associate professor of economics with tenure at the University of Chicago and a research associate at the NBER, where he is affiliated with the Productivity, Innovation, and Entrepreneurship program. He also is affiliated with the Centre for Economic Policy Research.

Akcigit's research focuses on economic growth, productivity, firm dynamics, and the economics of innovation. His work aims to uncover the sources of technological progress and innovation that serve as engines of long-run economic growth. He is also interested in the role of public policy in growth, with a focus on environmental regulations, public research and funding for universities, and industrial policies such as R&D tax credits and corporate taxation.

Some of his current papers explore the impact of trade and foreign competition on innovation, the role of political connections in reducing innovation, and the social origins and family backgrounds of inventors.
His research has been published in leading economics journals and has been supported by the Ewing Marion Kauffman Foundation, the Alfred P. Sloan Foundation, and the National Science Foundation. He is the recipient of a CAREER Award from the National Science Foundation.

Akcigit holds a BA in economics from Koç University in Istanbul and a PhD in economics from MIT. Prior to joining the University of Chicago in 2015, he was an assistant professor of economics at the University of Pennsylvania.

Stefanie Stantcheva

Stefanie Stantcheva is a professor of economics at Harvard University and a research associate at the NBER, where she is affiliated with the Public Economics and Political Economy programs. She is a research fellow at the Centre for Economic Policy Research.

Stantcheva's research focuses on the optimal design of tax systems and public policies, taking into account labor market features, complex social preferences, and long-term effects such as human capital acquisition and innovation by individuals and firms. Part of her work is centered around the study of empirical effects of taxation of individuals and firms, on inequality, top incomes, migration, human capital, and innovation.

In recent work, she is exploring the interplay between taxation and innovation using historical as well as modern-day data and the optimal design of R&D policies. She is also studying how people form social preferences regarding redistribution, using large-scale online survey and experiment tools.
Stantcheva is the recipient of a CAREER Award from the National Science Foundation and is a Sloan Research Fellow.

She holds a BA in economics from the University of Cambridge, a Master’s degree in economics and finance from Ecole Polytechnique, a Master's in economics from the Paris School of Economics, and a PhD in economics from MIT. She was a junior fellow at the Harvard Society of Fellows from 2014–16, before joining the Harvard faculty in 2016.
