In a special episode recorded live at Princeton University, the Odd Lots podcast hosts a panel discussion on defining currency. The panel features Iñaki Aldasoro from the Bank for International Settlements, Professor Rebecca Spang, and Stefan Ingves, former head of Sweden's central bank. The discussion explores money as a social convention, the interplay between public and private sector money, and the impact of technology on its form and function. The panel also discusses the traditional definition of money, its role as a store of value, and the design and perception of both physical and digital currencies, including stablecoins and central bank digital currencies.
