AAEA Presidential Address

Professor Hertel is Distinguished Professor of Agricultural Economics at Purdue University, where his research focuses on the economy-wide impacts of global trade and environmental policies.

Dr. Hertel is a Fellow, and Past-President, of the Agricultural and Applied Economics Association (AAEA). He is also the founder and Executive Director of the Global Trade Analysis Project (GTAP) which now encompasses more than 10,000 researchers in 150 countries around the world ( This Project maintains a global economic data base and an applied general equilibrium modeling framework which are documented in the book: Global Trade Analysis: Modeling and Applications, edited by Dr. Hertel, and published by Cambridge University Press in 1997.

Professor Hertel’s most recent research has focused on the impacts of climate change and mitigation policies on global land use and poverty. During the 2011-12 year he is on leave at Stanford University, where he is engaged in inter-disciplinary research on these topics.

Previously, Professor Hertel has conducted extensive research on the impacts of multilateral trade agreements, including the linkages between global trade policies and poverty in developing countries. His book on the poverty impacts of a WTO agreement (co-edited with Alan Winters) received the AAEA Quality of Communication award. Other AAEA awards include: Distinguished Policy Contribution and Outstanding Journal Article.
