The new framework for US monetary policy announced at the Jackson Hole symposium in August is a watershed event, for both the practice of macroeconomic policy, and the theory that lies behind it.
In the Federal Reserve Reform Act of 1977, following a period of “stagflation”, the US Congress gave the Fed three main objectives: maximum employment, stable prices and moderate long-term interest rates, in that order.
In the early 1980s, Paul Volcker crucially interpreted that mandate to place the greatest emphasis on stable prices. He broke the back of double-digit inflation but at the expense of increasing unemployment to above 10 per cent.
