The explanation of this book is that the 1929 depression was so wide, so deep, and so long because the international economic system was rendered unstable by British inability and U. S. unwillingness to assume responsibility for stabilizing it by discharging five functions:(1) maintaining a relatively open market for distress goods;
(2) providing countercyclical, or at least stable, longĀ term lending;
(3) policing a relatively stable system of exchange rates;
(4) ensuring the coordination of macroeconomic policies;
(5) acting as a lender of last resort by discounting or otherwise providing liquidity in financial crisis.
