Nobel Prize-winning economists Kenneth J. Arrow, Ph.D. (left), and Douglass C. North, Ph.D., get together for an informal chat on the occasion of Arrow’s presentation on “The Economics of New Antimalarial Drugs” Oct. 21 in the Bryan Cave Moot Courtroom of Anheuser-Busch Hall. Arrow, a longtime professor of economics at Stanford University, won the Nobel Memorial Prize in Economic Sciences with John R. Hicks in 1972 for their work on general economic equilibrium theory and welfare theory. North, the Spencer T. Olin Professor in Arts & Sciences at WUSTL, won the same honor with Robert Fogel in 1993 for research on the economic history of the United States and Europe. The Hilltop Campus event was sponsored by the Undergraduate Economics Association, the Center for Interdisciplinary Studies and the Department of Economics in Arts & Sciences.
