But I do think that modern macroeconomists need to be rounded up, on pain of loss of tenure, and sent to a year-long boot camp with the assembled monetary historians of the world as their drill sergeants. They need to listen to and learn from Dick Sylla about Alexander Hamilton’s bank rescue of 1825; from Charlie Calomiris about the Overend, Gurney crisis; from Michael Bordo about the first bankruptcy of Baring brothers; and from Barry Eichengreen, Christy Romer, and Ben Bernanke about the Great Depression.
