Marco Tabellini is an assistant professor in the Business, Government, and International Economy unit and is affiliated with the National Bureau of Economic Research (NBER), the Center for Economic Policy Research (CEPR), RF Berlin, and the Luxembourg Institute of Socio-Economic Research (LISER). He is also a faculty associate at the Salata Institute and a faculty affiliate at the Harvard Center for International Development (CID). Marco Tabellini explores how international and internal migration reshapes politics, societies, and the economy. His work investigates when and why immigration stirs political backlash, what drives successful social integration, and how migration alters societal boundaries in diverse countries such as the United States. He also examines the economic consequences of immigration, including its effects on labor markets and growth. Finally, his research sheds light on the role of climate as a powerful force shaping migration flows across time and place.
