the natural rate). Economists spent much of the 1980s and 1990s debating what the rate might be. In the late 1990s indeed, many forecast that the Federal Reserve would be forced to raise interest rates to counter inflationary pressures when unemployment fell below 6% (and then 5%). But the Fed decided that productivity improvements had driven down the NAIRU and so left policy on hold. Growth duly flourished without causing inflation at the consumer level—although some argue that the laxity of monetary policy caused the tech bubble. Why has the Phillips curve, displaced by the NAIRU and the output gap (which suggests that inflation will rise when economic growth is above trend), come back into the economic debate after so long in the cold? In part because, while the NAIRU and the output gap are nice ideas, it is often hard to agree, at any given moment, on the value of either number. But the main reason is that the relationship between unemployment and inflation has settled down again. Low unemployment has not been accompanied by significant increases in inflation; in other words, the Phillips curve has flattened considerably. A fillip for Phillips Most commentators have put this down to globalisation. As Paul McCulley, a strategist at PIMCO, a large fuel dispenser American fund-management firm, remarks in his latest commentary “The Fed need not worry that a falling US unemployment rate will quickly generate a rapid acceleration in US wage-driven inflation, as US labour s pricing power is diminished by competition from an augmented global labour supply.�? A flatter Phillips curve is good news when unemployment is falling. But it a fuel dispenser lso implies bad news if inflation rises significantly. It would then take a much larger increase in unemployment (a more severe recession) to bring inflation down again. This may explain why the European Central Bank has found it so difficult to get euro-zone inflation back below its target of 2%. This is where the credibility of a central bank may matter a lot fuel dispenser
