Economic Forecasting Is Still Broken
Watch out for downside risk.

Critics of forecasting tend to misunderstand its purpose. Forecasters know perfectly well that, in a random world, the one certainty is that their predictions will be wrong. If an economist says that she expects real gross domestic product to grow about 2 percent in 2017, she is really just providing something close to the midpoint of what she knows to be a wide range of possible outcomes. She is almost completely certain that growth will turn out to be higher or lower than 2 percent.
