I Think You’ll See that my Forecasting Record is Not Great.

“Most critiques of Krugman as a public intellectual begin with what is apparently an obligatory disclaimer, usually in the very first sentence — something to the effect that Krugman is a very accomplished and well-respected economist. Then comes the “But . . .” and the critique proceeds in earnest, often scathingly.

But why concede this honor to Krugman? So what if he won the Nobel Prize? The real test of Krugman’s mettle as an economist is the accuracy of his economic forecasting. The fact is that, with about three decades of evidence now in, Krugman’s track record, to use a technical term favored by economists, sucks.

He’s not always candid about this. But once, under the pressure of a televised debate with conservative talk-show host Bill O’Reilly, Krugman blurted out an understated if truthful self-evaluation: “Compare me . . . compare me, uh, with anyone else, and I think you’ll see that my forecasting record is not great.”

The most egregious example of “not great” is Krugman’s utterly incorrect 1982 prediction that inflation would soar. He made this prediction from no less lofty a perch than the White House, as staff member of the Council of Economic Advisers in the first Reagan administration. In a memo titled “The Inflation Time Bomb” Krugman wrote with co-author Lawrence Summers, “We believe that it is reasonable to expect a significant reacceleration of inflation . . . at least 5 percentage points to future increases in consumer prices. . . . This estimate is conservative.”

It also turned out to be hilariously, side-splittingly, knee-slappingly, rolling-on-the-floor wrong. Except for a tiny uptick the very next month, inflation didn’t rise; it fell. Four years later, it had fallen to 1.18 percent, a rate so low as to border on deflation.”
