Will Davies of Goldsmith's, University of London and author of The Limits of Neoliberalism talks with EconTalk host Russ Roberts about the ideas in his book.

Davies argues for the value of a completely different perspective and pushes for a reduction in the influence and status of economists as policymakers and influencers. Along the way he gives his perspective on the role of economists in the financial crisis and in antitrust policy.

Adam Cifu of the University of Chicago's School of Medicine and co-author (with Vinayak Prasad) of Ending Medical Reversal explores this question with EconTalk host Russ Roberts. Cifu shows that medical reversal--the discovery that prescribed medical practices are ineffective or harmful--is distressingly common. He contrasts the different types of evidence that support or discourage various medical practices and discusses the cultural challenges doctors face in turning away from techniques they have used for many years.

Adam Ozimek of Moody's Analytics and blogger at Forbes talks with EconTalk host Russ Roberts about why economists change their minds or don't.

In this conversation, Tetlock discusses the meaning, reliability, and usefulness of trying to assign probabilities to one-time events.

Did Ben Bernanke and the Fed save the U.S. economy from disaster in 2008 or did the Fed make things worse? Why did the Fed reward banks that kept reserves rather than releasing funds into the economy? George Selgin of the Cato Institute tries to answer these questions and more in this conversation with EconTalk host Russ Roberts. Selgin argues that the Fed made critical mistakes both before and after the collapse of Lehman Brothers by lending to insolvent banks as well as by paying interest on reserves held at the Fed by member banks.

If you have 250 million pounds of food to give away every year to local food banks how should you do it? Canice Prendergast of the University of Chicago's Booth School of Business talks with EconTalk host Russ Roberts about how he and a team of economists created an artificial currency and a daily auction for the national food bank Feeding America so that local food banks could bid on the types of food that were the most valuable to them. Prendergast explains the results of the new system and the cultural and practical challenges of bringing prices, even artificial ones, to a world accustomed to giving things away.

Are we on the verge of driverless cars and other forms of autonomous robots and artificial intelligence? David Mindell of MIT and the author of Our Robots, Ourselves talks with EconTalk host Russ Roberts about the robotic revolution. Mindell argues that much of the optimism for autonomous robots ignores decades of experience with semi-autonomous robots in deep-sea operation, space, air, and the military. In all of these areas, the role of human supervision remains at a high level with little full autonomy. Mindell traces some of the history of the human interaction with robots and artificial intelligence and speculates on what the future might hold.

While Ridley agrees that humans have made the climate warmer, he argues that the impact is small or positive over some temperature ranges and regions.

Though Weitzman concedes that our knowledge of the climate is quite incomplete, he suggests that it is prudent to take serious measures, including possibly geo-engineering, to reduce the accumulation of carbon dioxide in the atmosphere.

Bent Flyvbjerg of Oxford University speaks with EconTalk host Russ Roberts about the political economy of megaprojects--massive investments of a billion dollars or more in infrastructure or technology.

Flyvbjerg explores the reasons for the poor predictions and poor performance of giant investment projects and what might be done to improve their effectiveness.

Did an 800-year old piece of parchment really change the world?

He encourages trustees of museums to see their job more as tough-minded advisors and less as financiers of museum budgets.

Leonard Wong of the Strategic Studies Institute at the U.S. Army War College talks with EconTalk host Russ Roberts about honesty in the military.

This creates a tension for an institution that prides itself on honesty, trust, and integrity. The conversation closes with suggestions for how the military might reform the compliance and requirement process.

Scott Sumner, of Bentley University talks with EconTalk host Russ Roberts about interest rates. Sumner suggests that professional economists sometimes confuse cause and effect with respect to prices and quantities.
