Creating a Learning Society KENNETH J. ARROW LECTURE SERIES KENNETH J. ARROW LECTURE SERIES Kenneth J. Arrow’s work has shaped the course of economics for the past sixty years so deeply that, in a sense, every modern economist is his student. His ideas, style of research, and breadth of vision have been a model for generations of the boldest, most creative, and most innovative economists. His work has yielded such seminal theorems as general equilibrium, social choice, and endogenous growth, proving that simple ideas have profound effects. The Kenneth J. Arrow Lecture Series highlights economists, from Nobel laureates to groundbreaking younger scholars, whose work builds on Arrow’s scholarship as well as his innovative spirit. The books in the series are an expansion of the lectures that are held in Arrow’s honor at Columbia University. JOSEPH E. STIGLITZ AND BRUCE C.

Arrow, who received his Ph.D. from Columbia in 1951. His thesis, later published as Individual Choice and Social Values, was a landmark in economics, philosophy, and political science. In the more than sixty years that followed, Ken went on to become a giant in economics, political science, organization theory, and operations research. Columbia University has had a long line of distinguished graduates and faculty—including six Nobel Prizes in the past thirteen years. The faculty list for economics includes Milton Friedman, who taught at Columbia for ten years; Arthur Burns, who served on President Eisenhower’s Council of Economic Advisers from 1953 to 1956 and as chair of the Federal Reserve Board from 1970 to 1978; and Wesley Mitchell, who along with Burns played a central role in founding the National Bureau of Economic Research, one of the nation’s most important think tanks, which focused in its earlier years on enhancing understanding of economic fluctuations. There are a host of other greats, known more to those within the economics profession than those outside, including Harold Hotelling, Albert Hart, and John Bates Clark (whose namesake medal is awarded every year to the economist under forty who has made the most significant contribution to economics; Arrow was the fifth recipient of the honor.) With all of these potential luminaries, our decision to honor Kenneth Arrow was easy: No individual has done more to change how we think about economics—and about society beyond economics—during the past six decades. In a sense, virtually all theorists—and most policymakers—of our generation are students of Arrow (and, it might be added, our students can be considered their “grandstudents”). Ideas that
