Orley C. Ashenfelter
Joseph Douglas Green 1895 Professor of Economics
As Director of the Office of Evaluation of the US Department of Labor in 1972, Professor Ashenfelter began the work that is now widely recognized as the separate field of "quantitative social program evalution." He is also regarded as the originator of the use of so-called "natural experiments" to infer causality about economic relationships. He has also been the leader in the very recent emphasis in quantitative economic analysis on the use of creative methods of data collection. His innovative research has spanned a broad array of topics in the economic analysis of labor markets.
Professor Ashenfelter has been a Guggenheim fellow, a fellow in the Center for Advanced Study in the Behavioral Sciences and the Benjamin Meeker Visiting Professor at the University of Bristol.
