EconTalk host Russ Roberts is interviewed by long-time EconTalk guest Michael Munger about Russ's new book, How Adam Smith Can Change Your Life: An Unexpected Guide to Human Nature and Happiness. Topics discussed include how economists view human motivation and consumer behavior, the role of conscience and self-interest in acts of kindness, and the costs and benefits of judging others. The conversation closes with a discussion of how Smith can help us understand villains in movies.

David Autor of the Massachusetts Institute of Technology talks with EconTalk host Russ Roberts about the future of work and the role that automation and smart machines might play in the workforce. Autor stresses the importance of Michael Polanyi's insight that many of the things we know and understand cannot be easily written down or communicated. Those kinds of tacit knowledge will be difficult for smart machines to access and use. In addition, Autor argues that fundamentally, the gains from machine productivity will accrue to humans. The conversation closes with a discussion of the distributional implications of a world with a vastly larger role for smart machines.

Martha Nussbaum of the University of Chicago and author of Creating Capabilities talks with EconTalk host Russ Roberts about an alternative to GDP for measuring economic performance at the national level. She is a proponent of the capabilities approach that emphasizes how easily individuals can acquire skills and use them, as well as the capability to live long and enjoy life. Nussbaum argues that government policy should focus on creating capabilities rather than allowing them to emerge through individual choices and civil society.

Thomas Piketty of the Paris School of Economics and author of Capital in the Twenty-First Century talks to Econtalk host Russ Roberts about the book. The conversation covers some of the key empirical findings of the book along with a discussion of their significance.

Paul Pfleiderer, C.O.G. Miller Distinguished Professor of Finance at the Graduate School of Business at Stanford University, talks with EconTalk host Russ Roberts about his recent paper critiquing what Pfleiderer calls "Chameleon Models," economic models that are thought to explain the real world with little analysis of the accuracy of their assumptions. Also discussed are Akerlof's market for lemons model, Friedman's idea that assumptions do not have to be reasonable as long as the model predicts what happens in the real world, and the dangers of leaping from a model's results to making policy recommendations.

Nathan Blecharczyk, co-founder and chief technology officer of Airbnb, talks with EconTalk host Russ Roberts about Airbnb, one of the earliest companies to use technology to allow individuals to share underused resources, and in the case of Airbnb, housing. Blecharczyk and Roberts discuss how a design conference and the Democratic National Convention got Airbnb started, how the company aligns incentives to overcome the trust problem of house-sharing, and the rise of technology and online social networks to make a new business model possible. Along the way, Blecharczyk gives his take on the role of luck vs. skill in entrepreneurial success and how Airbnb plans to expand its product offerings in the future.

Daphne Koller of Coursera talks with EconTalk host Russ Roberts about online educational website Coursera and the future of education both online and via bricks-and-mortar. Koller, co-founder of Coursera with Andrew Ng, explains how Coursera partners with universities, how they try to create community and interaction, and the likely impact of widespread digital education on universities and those who want to learn. The conversation includes a discussion of why Koller left a chaired position in computer science at Stanford University to run a for-profit start-up in a crowded field.

Terry Anderson, Distinguished Fellow at the Property and Environment Research Center (PERC) and Senior Fellow at the Hoover Institution, talks to EconTalk host Russ Roberts about free-market environmentalism, the dynamics of the Yellowstone ecosystem, and how property rights can protect natural resources.

Barry Weingast, professor of political science at Stanford University and senior fellow at Stanford's Hoover Institution, talks with EconTalk host Russ Roberts about the nature of law. Weingast takes issue with some of the standard views of law, and proposes a better way to understand law. The two discuss the fundamental principles of law, how it can emerge in a decentralized way to resolve disputes over property and other commercial and social interactions. Examples include Iceland, Ancient Greece, and California during the gold rush. Also considered are how laws coordinate expectations and the way that social pressure can be used to enforce law in a decentralized fashion.
