The problem on the desk

Can individual rankings be combined into a social ranking while preserving several attractive requirements at once? Arrow’s impossibility result showed that the specified requirements cannot all hold together.1

In their own words

That’s a topic I know virtually nothing about. Therefore, I am especially interested in getting involved and learning about it.

A recurring reply to invitations to work on an unfamiliar topic, as recalled by Levin and Dixit.

A story

A question at RAND

The INFORMS memorial locates the formulation of Arrow’s social-choice theory and impossibility theorem in his RAND work. That research became the doctoral dissertation and the subsequent book.5

Around Arrow

  • co-author Theodore E. Harris Arrow, Theodore Harris and Jacob Marschak co-authored a 1951 paper on inventory theory.5

The card in the book

Born in New York City, he studied at the City College of New York (B.S. in social science with a mathematics major, 1940) and at Columbia University (M.A. in mathematics, 1941), and served as a weather officer in the US Army Air Corps from 1942 to 1946. After research at the Cowles Commission in Chicago he joined Stanford in 1949, moved to Harvard in 1968, and returned to Stanford in 1979. His Columbia doctoral dissertation was Social Choice and Individual Values, with the impossibility theorem; with Gérard Debreu he proved the existence of competitive equilibrium; and he studied information as an economic variable, in medical care, insurance and learning by doing. He shared the 1972 Nobel Memorial Prize in Economic Sciences with John Hicks.

Main works Social Choice and Individual Values (1951; 2nd ed. 1963); “Existence of an equilibrium for a competitive economy”, with G. Debreu (Econometrica 22, 1954); “Uncertainty and the welfare economics of medical care” (American Economic Review 53, 1963); Essays in the Theory of Risk-Bearing (1971).
