Today's guest is Nobel Prize-winning economist Alvin E. Roth, the author of Moral Economics: From Prostitution to Organ Sales, What Controversial Transactions Reveal About How Markets Work.
He talks with Nick Gillespie about why some voluntary transactions provoke moral outrage even when no one is being directly harmed. Roth explains why black markets often emerge when governments try to ban activities with persistent demand, why both markets and prohibitions require social support to function, and how unintended consequences can make moralistic policies backfire. They discuss the war on drugs, prostitution, surrogacy, same-sex marriage, price gouging, and why Iran remains the only country in the world with a legal market for kidney donors.
They also explore Roth's work designing kidney exchange networks and school choice systems, how digital technology and private transactions make certain bans harder to enforce, and why harm reduction may work better than prohibition in areas ranging from drug policy to sex work.
