Network Science's Chief Economist

Matthew O. Jackson is perhaps the world’s most renowned scholar of the economics of networks; as a 2005-06 CASBS fellow, he wrote most of his still-influential book Social and Economic Networks. In this wide-ranging conversation with 2025-26 CASBS fellow Rajiv Sethi, Jackson discusses his foundational work on strategic modeling of networks, empirical applications on the role of economic connectedness in influencing people’s life trajectories in the U.S., related multi-disciplinary and cross-national work he is undertaking at the Sant Fe Institute, and recent cutting-edge work using large language models to gain insights into human motivations and behaviors.
