Along the way he discusses the implications of Moneyball for the movie business and other industries, the peculiar ways that Moneyball influenced the strategies of baseball teams, the corruption of college football, and the challenge and tragedy of kids who live on the streets with little education or prospects for success.

Bruce Yandle of Clemson University explains why politics makes such strange bedfellows and the often peculiar alliance of self-interested special interests with more altruistic motives.

Mike Munger of Duke University recounts the harrowing (and fascinating) experience of being in the path of a hurricane and the economic forces that were set in motion as a result. One of the most important is the import of urgent supplies when thousands of people are without electricity. Should prices be allowed to rise freely or should the government restrict prices? Listen in as Munger and EconTalk host Russ Roberts discuss the human side of economics after a catastrophe.

Don Boudreaux of George Mason University talks about the fundamental principles of economics and civilization: spontaneous order and law. Drawing on volume one of Friedrich Hayek's classic, Law, Legislation and Liberty, Boudreaux talks about the distinction between law and legislation, the appropriate role of judges, and how the fulfillment of our expectations allows us to pursue our goals and dreams.

Bryan Caplan and Russ Roberts discuss the economics of discrimination and government's regulation of labor markets. They talk about the role of the profit motive in reducing or eliminating discrimination and the role of government, particularly in European labor markets. When does government regulation reduce or enforce discrimination? How do other labor market regulations affect employment and unemployment? What is the impact on the European and American standard of living? Does money buy happiness? Does it depend on whether it is earned or received as welfare? These are some of the topics that come up in this wide-ranging conversation.

Stanley Engerman of the University of Rochester talks about slavery throughout world history, the role it played (or didn't play) in the Civil War and the incentives facing slaves and slave owners.

Engerman knows as much as anyone alive about the despicable human arrangement called slavery and the vastness and precision of his knowledge is on display in this interview.

Sam Peltzman of the University of Chicago talks about his views on safety, regulation, unintended consequences and the political economy of bad regulation.
