Kenneth Arrow

Kenneth J. Arrow was a Nobel Prize-winning economist who served as the Joan Kenney Professor of Economics and Professor of Operations Research, Emeritus, at Stanford University. He is best known for his pioneering contributions to general equilibrium theory and welfare theory, for which he shared the 1972 Nobel Memorial Prize in Economic Sciences with Sir John Hicks. His 1951 book Social Choice and Individual Values introduced Arrow's Impossibility Theorem, a foundational result in social choice theory. He passed away on February 21, 2017, at the age of 95.
