Networks in Economic Models Session 4: Friendship Networks and Social Diversity at School

The study of social network effects has expanded in recent years, with an increased availability of data coupled with advances in theoretical and empirical modeling of these effects. These developments highlight the role of networks in influencing important aspects of individual behavior and inform a growing appreciation that behavior frequently targeted by policy can be greatly affected by the behavior of their friends and associates.

This academic conference featured recent innovations in the literature of social networks presented by experts in this area. In addition to discussing issues related to the estimation of econometric models in the possible presence of network effects, the conference featured several empirical investigations of social and economic issues important to social well-being.

This event was co-sponsored by Sciences Po and the Georgetown University Global Economic Challenges Network.

Julien Grenet is a senior researcher at the Centre National de la Recherche Scientifique, professor of economics at the Paris School of Economics, and deputy director of the Institut des Politiques Publiques. His current research lies at the intersection of market design and the economics of education and employs various methodological approaches (quasi-experimental research design, structural estimation, fieldwork).

Emeric Henry is professor of economics and head of the Department of Economics at Sciences Po. He is also a research fellow at the Centre for Economic Policy Research. Henry is a microeconomist, using theory, experimental, and empirical methods. His research interests include economics of innovation, political economy, and the economics of social media.

Matthew O. Jackson is the William D. Eberle Professor of Economics at Stanford University and an external faculty member of the Santa Fe Institute. He previously worked at Northwestern University and the California Institute of Technology. Jackson's research interests include game theory, microeconomic theory, and the study of social and economic networks, on which he has published many articles and the books The Human Network (2019) and Social and Economic Networks (2010).

Jean-Marc Robin is a professor of economics at the Department of Economics of Sciences Po, Paris. He was previously a professor of economics at the University of Paris 1-PSE and at the University College London.
