Great to see The Economist discussing not only the Austrian business cycle theory but also drawing attention to its Misesian roots.
JOHN MAYNARD KEYNES is back. The British economist has modern intellectual champions in Paul Krugman and Robert Skidelsky. For all today’s talk of austerity, a policy of Keynesian fiscal stimulus was adopted by most governments in the immediate aftermath of the credit crisis.
In contrast policymakers seem to show a lot less interest in the economic ideas of the “Austrian school” led by Ludwig von Mises and Friedrich Hayek, who once battled Keynes for intellectual supremacy. Yet the more you think about recent events, the odder that neglect seems.
A one-paragraph explanation of the Austrian theory of business cycles would run as follows. Interest rates are held at too low a level, creating a credit boom. Low financing costs persuade entrepreneurs to fund too many projects. Capital is misallocated into wasteful areas. When the bust comes the economy is stuck with the burden of excess capacity, which then takes years to clear up.
Take that analysis piece by piece. Were interest rates held too low? The case seems self-evident for Ireland and Spain, where the European Central Bank was setting a one-size-fits-all monetary policy. Many people would also argue that the Federal Reserve kept rates too low. Some lay the housing boom of 2003-06 at the Fed’s door, others criticise the central bank’s tendency to slash rates whenever the financial markets wobbled….
