Matt is a MacArthur fellow and one of America’s brightest economists. He is best known for exploring the idea that human choices are not fully rational. I also like his argument that if you exercise too much moral suasion against a person, rather than heeding your opinion the person will simply stop listening. Read an interview with Matt here. At the bottom of the interview you will find links to his working papers. Thanks to www.2blowhards.com for the pointer.
