William Easterly of New York University talks with EconTalk host Russ Roberts about the oft-heard claim that poor countries led by autocrats grow faster than poor countries that are democratic. Drawing on a recent paper, "Benevolent Autocrats," Easterly argues that while some autocracies do indeed grow very quickly, a much greater number do not. Yet, the idea that the messiness of democracy is inferior to a dictatorship remains seductive. Easterly gives a number of arguments for the perennial appeal of autocracy as a growth strategy. The conversation closes with a discussion of the limitations of our knowledge about growth and where that leaves policymakers.

Tim Harford, author and journalist, talks with EconTalk host Russ Roberts about Adapt, Harford's book on the virtues of failure and the trial and error process. Harford argues that success is more likely when there is experimentation and trial and error followed by adapting, rather than following a top-down, ex ante plan driven by expertise. The conversation looks at the what war can teach us about information, knowledge, and planning, the challenge of admitting mistakes, and the implications of trial and error for our daily lives.

William Byers of Canada's Concordia University and author of The Blind Spot talks with EconTalk host Russ Roberts about the nature of knowledge, science and mathematics. Byers argues that there is an inherent uncertainty about science and our knowledge that is frequently ignored. Byers contrasts a science of wonder with a science of certainty. He suggests that our knowledge of the physical world will always be incomplete because of the imperfection of models and human modes of thought relative to the complexity of the physical world. The conversation also looks at the implications of these ideas for teaching science and social science.

Bryan Caplan, economist and author of 'Selfish Reasons to Have More Kids', challenges the belief that parents have a lasting influence on their children's lives. He discusses the nature versus nurture debate, parental influence on behavior, boosting children's intelligence, biases in parenting research, and the impact of population on poverty and the environment. Caplan also shares valuable advice on easier parenting, including tips on sleep, discipline, independence, and the common complaints kids have about their parents.

John Papola of Emergent Order talks with EconTalk host Russ Roberts about their collaboration creating rap videos based on the ideas of John Maynard Keynes and F. A. Hayek. Their first was "Fear the Boom and Bust" which was released January 25, 2010. This past week they released "Fight of the Century." The latest video discusses the overarching differences between the philosophies of Keynes and Hayek and their views on whether government spending promotes recovery from an economic downturn and whether it leads to prosperity. In this conversation, Papola and Roberts discuss some of the underlying ideas in the video--whether the military spending of World War II ended the Great Depression, the debate between Malthus and Say and their influence on Keynes and Hayek, and the fundamental differences between Keynes and Hayek in how economic prosperity is created.

Ariel Rubinstein of Tel Aviv University and New York University talks with EconTalk host Russ Roberts about the state of game theory and behavioral economics, two of the most influential areas of economics in recent years. Drawing on his Afterword for the 60th anniversary edition of Von Neumann and Morgenstern's Theory of Games and Economic Behavior, Rubinstein argues that game theory's successes have been quite limited. Rubinstein, himself a game theorist, argues that game theory is unable to yield testable predictions or solutions to public policy problems. He argues that game theorists have a natural incentive to exaggerate its usefulness. In the area of behavioral economics, Rubinstein argues that the experimental results (which often draw on game theory) are too often done in ways that are not rigorous. The conversation concludes with a plea for honesty about what economics can and cannot do.

Mike Munger of Duke University talks with EconTalk host Russ Roberts about microfinance. Munger argues that cultural forces make it difficult for some families to save, and the main value of microfinance is to allow a higher level of savings. Families are willing to save via microfinance even though returns can be negative. Munger argues that this counterintuitive result is possible when other means of savings are unavailable. Munger also discusses microfinance that is used for entrepreneurship and the potential role for microfinance in development.

Dani Rodrik of Harvard University talks with EconTalk host Russ Roberts about trade, the labor market, and trade policy. Drawing on a recent paper with Margaret McMillan on trade and productivity, Rodrik argues that countries have very differing abilities to respond to increases in productivity that allow production to expand using fewer workers in a particular sector. When workers are displaced by productivity increases, what is their next best alternative? Rodrik discusses how this varies across countries and policies that might improve matters. He argues that poor countries should subsidize new products as a way of overcoming uncertainty and externalities from new ventures.

Gavin Andresen, Principal of the BitCoin Virtual Currency Project, talks with EconTalk host Russ Roberts about BitCoin, an innovative attempt to create a decentralized electronic currency. Andresen explains the origins of BitCoin, how new currency gets created, how you can acquire BitCoins and the prospects for BitCoin's future. Can it compete with government-sanctioned money? How can users trust it? What threatens BitCoin and how might it thrive?

Vincent Reinhart of the American Enterprise Institute talks with EconTalk host Russ Roberts about the government interventions and non-interventions into financial markets in 2008. Conventional wisdom holds that the failure to intervene in the collapse of Lehman Brothers precipitated the crisis. Reinhart argues that the key event occurred months earlier when the government engineered a shotgun marriage of Bear Stearns to JP Morgan Chase by guaranteeing billion of Bear's assets and sending a signal to creditors that risky lending might come without a cost. Reinhart argues that there is a wider menu of choices available to policy makers than simply rescue or no rescue, and that it is important to take action before the crisis comes to a head.
