What is capitalism, really? Drawing on Adam Smith, Douglass North, and his own experience as a teacher and economist, economist Michael Munger of Duke University discusses three stages of economic development with EconTalk's Russ Roberts: voluntary exchange, markets, and capitalism. Along the way, the conversation explores the moral and institutional foundations that make impersonal exchange possible, the transformative power of the division of labor, and how capitalism uniquely enables "time travel" through liquidity and equity finance. The conversation closes with a discussion of human needs beyond material well-being.
