There's one person who has thought more about the philosophical and economic principles undergirding the Federal Reserve, central banks, and independent agencies - Paul Tucker. In his new book, Global Discord Values and Power in a Fractured World Order, Paul takes a step back to consider international organizations, and how their institutional design and legitimacy hold in a changing global power dynamic. 
Carey Mott, from the Yale Program on Financial Stability, joins me as cohost in this interview with Paul.
