James A. Robinson has conducted influential research in the field of political and economic development and the relationships between political power and institutions and prosperity. His work explores the underlying causes of economic and political divergence both historically and today and uses both the mathematical and quantitative methods of economics along with the case study, qualitative, and fieldwork methodologies used in other social sciences. Robinson has a particular interest in Latin America, where he has taught every summer for over 25 years at the University of the Andes in Bogotá, Colombia, and in sub-Saharan Africa. He has conducted fieldwork and collected data in Bolivia, Colombia, Haiti, the Democratic Republic of the Congo, Nigeria, and Sierra Leone. He has published three books co-authored with Daron Acemoglu, an Institute Professor of Economics at MIT: Economic Origins of Dictatorship and Democracy (2005), Why Nations Fail: The Origins of Power, Prosperity, and Poverty (translated into 41 languages since its publication in 2012), and, most recently, The Narrow Corridor: States, Society and the Fate of Liberty (2019), which examines the incessant and inevitable struggle between states and society, and gives an account of the deep historical processes that have shaped the modern world.
