Re-writing history

By the way, in the middle of the several comments praising the winners of the Sveriges Riksbank Prize in Economics there will be a lot of misplaced acclaim. Here is one example from the Huffington Post:

"Sargent famously weighed in on the fight against inflation in the early 1980s. Many economists believed it would take years of high interest rates to bring inflation down. But Sargent believed that inflation could be tamed much faster if the Federal Reserve acted enough to break the public's expectations that prices would continue to rise rapidly. That is basically what happened: Then-Fed Chairman Paul Volcker raised interest rates so quickly and so much that inflation expectations were shattered."

So now, if you believe this report, Sargent and Lucas were right about the costless disinflation of the 1980s. Forget that disinflation had to do with falling commodity prices, caused by the hike in interest rates, and with the weakening of the labor force, which faced what was, in the US up to that point, the worse recession since the Great Depression. Unemployment in the US reached 11%, but it was inflationary expectations that mattered. And the Huff Post is a progressive site, isn't it?!
