What about the claim that the Fed is risking inflation? It isn’t. Mr. Laffer seems panicked by a rapid rise in the monetary base, the sum of currency in circulation and the reserves of banks. But a rising monetary base isn’t inflationary when you’re in a liquidity trap. America’s monetary base doubled between 1929 and 1939; prices fell 19 percent. Japan’s monetary base rose 85 percent between 1997 and 2003; deflation continued apace.
