George Selgin has been highly influential in shaping my own thinking about monetary policy. My critique of U.S. monetary policy in the early-to-mid 2000s that has been a prominent part of this blog is based on Selgin's work on deflation. Selgin, though, has other research interests. This past summer he published a book called Good Money which I posted on here. Now you can listen to Selgin discuss his new book in this podcast interview. For more commentary on this book, see Alex Tabarrok's review of the book here.
