Andrés M. Guiot-Isaac is a Post-doctoral Fellow in Economic History at the London School of Economics. Currently, Andrés is working on his first monograph on the emergence of an economic technocracy in Colombia, which builds on his doctoral research at the University of Oxford. This project explores the construction of state capacities in developing countries to act on economies and influence socioeconomic outcomes by focusing on the transnational financial and knowledge exchanges that reshaped the Colombian state during the two decades when ‘development’ became a dominant organizing framework in academic, multilateral and policy circles (1950-1970). Andrés’ work on the first World Bank mission to Colombia and the ‘development experts’ Albert O. Hirschman and Lauchlin Currie has been published in the History of Political Economy and Oeconomia.
