James J. Heckman, Henry Schultz Distinguished Service Professor of Economics, University of Chicago, and Distinguished Chair of Microeconometrics, University College London and University College Dublin Dr. Heckman's work has been devoted to developing a scientific basis for economic policy evaluation, with special emphasis on models of individuals and disaggregated groups, and to the problems and possibilities created by heterogeneity, diversity, and unobserved counterfactual states. His recent research deals with issues such as evaluation of social programs, econometric models of discrete choice and longitudinal data, the economics of the labor market, and alternative models of the distribution of income. He has published more than 200 articles and several books. Heckman shared the Nobel Memorial Prize in Economics in 2000 with Daniel McFadden for his pioneering work in econometrics and microeconomics. He also is a recipient of the Jacob Mincer Award for Lifetime Achievement in Labor Economics, the University College Dublin Ulysses Medal, and the Aigner award from the Journal of Econometrics. Dr. Heckman is considered to be among the 10 most influential economists in the world. He received his Ph.D. degree in economics from Princeton University in 1971.
