James A. Robinson is a University Professor at the University of Chicago with joint appointments in the Harris School of Public Policy and Department of Political Science. An economist and political scientist, he conducts influential research on political and economic development, examining how political power, institutions, and prosperity interact through both quantitative economic modeling and qualitative fieldwork methodologies. Robinson's research focuses on institutional analysis and political economy, with deep regional expertise in sub-Saharan Africa and Latin America. He has conducted extensive fieldwork across Bolivia, Colombia, Haiti, Democratic Republic of Congo, Nigeria, Sierra Leone, South Africa, and Zimbabwe, investigating how historical institutions shape contemporary economic outcomes. His interdisciplinary approach integrates economic theory with anthropological and historical case studies to explain patterns of economic divergence and political stability. Recent publications (2023-2025) reveal persistent themes in institutional persistence, state-society dynamics, and the cultural foundations of development. His work increasingly examines the interaction of economic and political inequality, the role of non-institutional factors in leadership strategies, and the historical roots of peripheral development trajectories across diverse global contexts. Scientific recognition includes: 2024 Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel Fellow, Institute of African Studies at the University of Nigeria, Nsukka Robinson co-authored three seminal books with Daron Acemoglu: Economic Origins of Dictatorship and Democracy (theoretical foundations of regime stability), Why Nations Fail (translated into 41 languages, arguing inclusive institutions drive prosperity), and The Narrow Corridor (analyzing state-society struggles for liberty). He maintained a 28-year summer school at Colombia's University of the Andes (1994-2022) and continues active research collaborations across Africa and Latin America.
