Sherman Robinson is a Senior Research Fellow at the International Food Policy Research Institute (IFPRI) and Professor of Economics (emeritus) at the University of Sussex. He joined the Economics Department at Sussex in 2004 and then accepted a joint appointment at the Institute of Development Studies (IDS) in 2005. He worked at IFPRI from 1993 to 2004 as Director of the Trade and Macroeconomics Division and rejoined IFPRI as a Senior Research Fellow in 2011. Before joining IFPRI, he was: Professor of Agricultural and Resource Economics at the University of California, Berkeley; Economist, Senior Economist and Division Chief in the Research Department of the World Bank; Assistant Professor of Economics at Princeton University; and Lecturer in Economics at the London School of Economics. He has held visiting senior-staff appointments at the Economic Research Service, U.S. Department of Agriculture; the U.S. Congressional Budget Office; and the President's Council of Economic Advisers (in the Clinton administration), where he largely worked on trade issues, including regional trade agreements, GATT/WTO negotiations, and the North American Free Trade Agreement (NAFTA). He is a leading expert on computable general equilibrium (CGE) simulation models, which have become a standard tool of policy analysis. He has developed global, national, and sub-national models, focusing on issues of trade policy, long-run growth, income distribution, agricultural policy, pollution control, water systems, and the impact of climate change. His recent work has focused on the use of entropy estimation methods to estimate data and parameters for simulation models, and on developing modeling systems to integrate economic models (global and national, partial and general equilibrium) with water basin management and hydrology models to analyze issues of long-run climate change.
