Peter Leeson of George Mason University joins the podcast today to discuss his latest book, WTF?!: An Economic Tour of the Weird. We discuss the economic reasoning behind some of history's strangest practices: ordeals that were used to determine innocence or guilt in medieval Europe, trials by battle that were used to settle land disputes in Norman England, wife auctions that happened during the Industrial Revolution, and the criminal prosecution of insects and rodents by ecclesiastical courts in Renaissance Italy. Also check out Peter's previous book, The Invisible Hook, about the economics of pirates. You won't regret it!
