Are central banks really necessary?
Gerald P. O鈥橠riscoll鈥檚 hard-hitting piece in today鈥檚 Wall Street Journal, "Debunking the Myths about Central Banks" is well worth reading. Among others, O鈥橠riscoll addresses the myth that 鈥渃entral banks are intrinsically necessary for market economies.鈥� As O鈥橠riscoll points out, however,
"A gold, or any commodity, standard places a natural limitation on money creation, which is the resource cost of extracting the commodity. It is only with fiat (paper) money that central banks are necessary to control the money supply."聽
One should not conclude from this that O鈥橠riscoll fallls prey to the myth of a central bank that is able to scientifically control the supply of fiat money independently of politics. In fact, he explodes this myth by pointing to the Fed under Chairmans Martin, Burns, Volcker, and Bernanke all of whose polices were powerfully shaped by the interests of the Presidents they served under. O鈥橠risoll concludes: 鈥淎 central bank is necessary as long as an economy is wedded to a fiat currency. And it may at times behave independently鈥攂ut not in the face of large-scale budget deficits, as we have today.鈥�
