James McGill Buchanan, Jr. (/bjuknn/; October 3, 1919 January 9, 2013) was an American economist known for his work on public choice theory (included in his most famous work The Calculus of Consent), for which he received the Nobel Memorial Prize in 1986. Buchanan's work initiated research on how politicians' and bureaucrats' self-interest, utility maximization and other non-wealth maximizing considerations affect their decision making. He was a member of the Board of Advisors of The Independent Institute, a member (and for a time the President) of the Mont Pelerin Society, a Distinguished Senior Fellow of the Cato Institute, and professor at George Mason University.
