The problem with economists is if you ask 2 economists their opinions, you get 3 opinions.
The other problem is that, while economists are great at telling you what happened, they tend not to be so great at telling you what's going to happen.
For example, in 2016, within minutes of it becoming clear Trump was going to win the election, this is what Krugman posted in his NY Times column:
"It really does now look like President Donald J. Trump, and markets are plunging. When might we expect them to recover?
Frankly, I find it hard to care much, even though this is my specialty. The disaster for America and the world has so many aspects that the economic ramifications are way down my list of things to fear.
Still, I guess people want an answer: If the question is when markets will recover, a first-pass answer is never."
Here's what the market looked like for the remainder of 2016. The point is that "never" came a lot earlier than Krugman envisioned.
