Edmund Phelps

Edmund Strother Phelps (July 26, 1933 – May 15, 2026) was an American economist and the recipient of the 2006 Nobel Memorial Prize in Economic Sciences.

Early in his career, he became known for his research at Yale's Cowles Foundation in the first half of the 1960s on the sources of economic growth. His demonstration of the golden rule savings rate, a concept related to work by John von Neumann, started a wave of research on how much a nation should spend on present consumption rather than save and invest for future generations.

Phelps was at the University of Pennsylvania from 1966 to 1971 and moved to Columbia University in 1971. His most seminal work inserted a microfoundation, one featuring imperfect information, incomplete knowledge and expectations about wages and prices, to support a macroeconomic theory of employment determination and price-wage dynamics. That led to his development of the natural rate of unemployment: its existence and the mechanism governing its size. In the early 2000s, he turned to the study of business innovation.

From 2001 he was the founding director of Columbia's Center on Capitalism and Society. He was McVickar Professor of Political Economy at Columbia from 1982 to 2021. On January 1, 2022, his title changed to McVickar Professor Emeritus of Political Economy.
