Nobel Laureate James M. Buchanan passed away today at the age of 93. He founded the field of public choice economics, and his writings have had a greater impact on me than any other economist I have read. This summer I heard stories about him from people who knew him, and apparently he didn’t always observe the rules of order in Liberty Fund conference discussions. When you win a Nobel Prize, I’m sure people will give you a little leeway too. I made this poster for Econlib to commemorate the passing of this giant of 20th century economics.
