James M. Buchanan, American economist and academic, Nobel Prize laureate (b. 1919)

James McGill Buchanan Jr. (; October 3, 1919 – January 9, 2013) was an American economist known for his work on public choice theory (included in his most famous work, co-authored with Gordon Tullock, The Calculus of Consent, 1962), for which he received the Nobel Memorial Prize in Economic Sciences 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 as well as of the Institute of Economic Affairs, a member (and for a time president) of the Mont Pelerin Society, a Distinguished Senior Fellow of the Cato Institute, and professor at George Mason University.
