Another Reason to Worry About the Economy
(Bloomberg Opinion) -- Will the U.S. dip into recession sometime in the coming year? Economists increasingly disagree on what will happen — and that in itself may be an ominous sign.
Every month, Bloomberg surveys dozens of economists — from banks, research firms, universities — on the outlook for the U.S. On average, as of Friday, they expected the economy to grow 2.2 percent during the next 12 months, adjusted for inflation. That said, there was a lot of variation, particularly on the down side: Predictions ranged from 3.2 percent growth to a 0.8 percent contraction. Here’s how that looks:
Variation can matter. Back in 2007, when I was managing a similar survey at the Wall Street Journal, I noticed that although economists weren’t very good at predicting recessions, they did tend to disagree more when one was imminent. That’s what happened before the downturns of 1990 and 2001, and what ultimately happened before 2008. It’s not a perfect indicator, and can spike without foreshadowing anything, but it’s worth watching.
So what’s happening now? To get a sense, I gathered the Bloomberg survey data from the end of each quarter, to see how much the forecasters disagreed. Specifically, I calculated the standard deviation — a measure of divergence from the average — of predictions for growth over the next 12 months. As of Friday, it stood at 0.76 percentage point, the largest dispersion since 2012, when Europe was still immersed in its debt crisis. Here’s a chart (unfortunately, the data don’t go back to before the last recession):
