From the EconTalk description:
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.
