Economist and author Don Boudreaux of George Mason University discusses the life and work of the economist James Buchanan with EconTalk host Russ Roberts. Buchanan received the Nobel Prize in 1986 for his work creating and developing public choice--the field which applies the tools of economics to politicians and political behavior. After discussing the importance of public choice, Boudreaux and Roberts focus on two contrarian articles of Buchanan's where he argues for the importance of markets and life as processes rather than problems to be solved analytically.
