Nassim Taleb, author of The Black Swan and Fooled by Randomness, talks with EconTalk host Russ Roberts about his latest thoughts on robustness, fragility, debt, insurance, uncertainty, exercise, moral hazard, knowledge, and the challenges of fame and fortune.

Paul Romer of Stanford University talks with EconTalk host Russ Roberts about charter cities, Romer's idea for helping the poorest of the poor around the world. Romer envisions a city where the rules about property and safety and contract and so on are rules that allow individuals to flourish in an urban setting in contrast to the cities they live in now where so many aspects of economic and personal life are dysfunctional. Charter cities would be havens for the world's poor and could be created on uninhabited land in either rich or poor countries. This concept raises many difficult practical questions--some of them are discussed here along with how Romer came to be interested in creating the concept and how he hopes to bring it to reality.

Mike Munger of Duke University talks with EconTalk host Russ Roberts about the world of profit, money, love, gifts, and incentives. What motivates people, self-interest or altruism? Both obviously. But how do these forces interact with each other? Does relying on one always provide a stronger incentive than the other? Do charities, for-profit businesses or government agencies do a better job providing a good or service? Munger and Roberts have a wide-ranging discussion across these issues including a section where they discuss whether Christmas gift-giving and gift-giving in general is inefficient.

Diane Ravitch of NYU talks with EconTalk host Russ Roberts about the ideas in her new book, The Death and Life of the Great American School System: How Testing and Choice Are Undermining Education. Ravitch argues that the two most popular education reform movements, accountability and choice, have had unintended consequences that have done great harm to the current generation of students. She argues that the accountability and testing provisions in legislation like No Child Left Behind and similar reforms have actually corrupted the testing process, taken time away from subjects other than math and reading, and failed even to boost success in math and reading. She argues that the empirical record has provided little evidence that school choice as it has been implemented has boosted achievement. The discussion closes with a discussion of what reforms might indeed make a difference.

Yochai Benkler of Harvard University talks to EconTalk host Russ Roberts about net neutrality, access to the internet, and innovation. Benkler argues in favor of net neutrality and government support of broadband access. He is skeptical of the virtues of new technology (such as the iPad) fearing that they will lead to less innovation. The conversation closes with a discussion of commons-based peer production--open source software and Wikipedia.

Arthur De Vany, of the University of California, Irvine, and creator of Evolutionary Fitness, talks with EconTalk host Russ Roberts about performance-enhancing drugs in baseball and Evolutionary Fitness, De Vany's ideas about diet and fitness. In the first part of the conversation, De Vany argues that there is little physiological or statistical evidence that steroid use increases home run totals in baseball. The second part of the conversation turns to De Vany's theories of diet and exercise. De Vany argues that our diet and exercise regime should take account of our evolutionary origins, an earlier time when we ate no grains and our exercise was a mix of intense activity punctuated by much milder activity. He argues that jogging is unhealthy and that we would live longer and feel better if we followed a different exercise routine than most Americans do today.

Steve Meyer, music industry veteran and publisher of the Disc and Dat Newsletter, talks with EconTalk host Russ Roberts about the evolution of the music industry and the impact of the digital revolution. After discussing his background and experience in marketing at Capitol Records and elsewhere, Meyer argues for the virtues and potential of the internet in enhancing the music industry. He points out that the internet allows numerous artists to make money through their music and particularly enhances revenue from live performances. He describes the challenges facing record companies as a failure of imagination and suggests that the full potential of the internet as a distribution channel has yet to be fully exploited.

Don Boudreaux of George Mason University talks with EconTalk host Russ Roberts about public choice: the application of economics to the political process. Boudreaux argues that political competition is a blunt instrument that works less effectively than economic competition. One reason for this bluntness is the voting process itself--where intensity does not matter, only whether a voter prefers one candidate to the other. A second reason is that political outcomes tend to be one-size-fits-all, which often leads to dissatisfaction. Boudreaux defends the morality of not voting, while Roberts, who does vote from time to time, concedes that one's vote is almost always irrelevant in determining the outcome.

Katherine Newman, Professor of Sociology at Princeton University, talks with EconTalk host Russ Roberts about Newman's case studies of fast-food workers in Harlem. Newman discusses the evolution of their careers and fortunes over time along with their dreams and successes and failures. The conversation concludes with lessons for public policy in aiding low-wage workers.

Barry Ritholtz, author of Bailout Nation: How Greed and Easy Money Corrupted Wall Street and Shook the World Economy, talks with EconTalk host Russ Roberts about the history of bailouts in recent times, beginning with Lockheed and Chrysler in the 1970s and continuing through the current financial crisis. In addition to the government role in aiding ailing companies, Ritholtz also looks at the role of the Fed in discouraging prudence through its efforts to keep asset prices and the stock market at high levels. The conversation closes with a discussion of what Ritholtz has learned from the crisis.
