Robin Hanson of George Mason University talks about the phenomenon of signalling--the ways people spend resources to convey information about ourselves to others. It begins with Hanson revisiting his theory from an earlier podcast that we spend too much on medicine because we need to signal our concern for friends and family. The conversation then moves onto apply Hanson's model of signalling to other areas of human behavior. This is a wide-ranging discussion covering not just medicine, but real estate transactions, the wooing of a spouse, the role of education in the job market, parenting, the economics of self-deception, and Robin's argument that we spend too much time on admirable activities.

Chris Anderson talks with EconTalk host Russ Roberts about his next book project based on the idea that many delightful things in the world are increasingly free--internet-based email with infinite storage, on-line encyclopedias and even podcasts, to name just a few. Why is this trend happening? Is it restricted to the internet? Is there really any such thing as a free lunch? Is free a penny cheaper than a penny or a lot cheaper than that? The conversation also covers whether economics has anything to say about free.

Drawing on the insights from his recent book, A Splendid Exchange: How Trade Shaped the World, Bernstein talks about the magic of spices, how trade in sugar explain why Jews ended up in Manhattan, the real political economy of the Boston Tea Party and the demise of the Corn Laws in England. The discussion closes with the political economy of trade today and the interaction between trade and income inequality.

EconTalk host Russ Roberts talks about the claim that for capitalism to succeed there have to be people at the bottom to do the unpleasant tasks and that the rich thrive because of the suffering of those at the bottom. He critiques the idea that capitalism is a zero sum game where to get ahead, someone has to fall back. He also looks at the evolution of the least pleasant jobs over time and how technology interacts with rising productivity to make the least pleasant jobs more pleasant.

Diane Coyle talks with EconTalk host Russ Roberts about the ideas in her new book, The Soulful Science: What Economists Really Do and Why it Matters. The discussions starts with the issue of growth--measurement issues and what economists have learned and have yet to learn about why some nations grow faster than others and some don't grow at all. Subsequent topics include happiness research, the politics and economics of inequality, the role of math in economics, and policy areas where economics has made the greatest contribution.

Christopher Coyne of West Virginia University and George Mason University's Mercatus Center talks with EconTalk host Russ Roberts about his book, After War: The Political Economy of Exporting Democracy. They talk about the successes and failures of America's attempts to export democracy after a war. In some cases, Japan and Germany, for example, after World War II, American efforts have led to stability and democratic institutions. In many other cases, Cuba, Somalia, and Haiti, for example, and so far, Iraq, American efforts have failed, often repeatedly and have sometimes made things worse. Coyne tries to identify factors that lead to an improved likelihood of success or failure. Ultimately, he concludes that a non-interventionist posture accompanied by unilateral free trade is more likely to benefit citizens under repressive governments.

Deirdre McCloskey of the University of Illinois at Chicago and the author of The Bourgeois Virtues talks with EconTalk host Russ Roberts about capitalism and whether markets make people more ethical or less. They also discuss Adam Smith's world view, whether people were nicer in the Middle Ages, and the role of prudence and love.
