Everybody interested in macroeconomics or macroeconomic policy should know this topic backwards and forwards by heart. My problem is that I do not see how I can add value to it. The only thing I can think of to do is to propose two rules:
- Paul Krugman is right.
- If you think Paul Krugman is wrong, refer to rule #1.
I do wish that those who were not bad actors who made mistakes would 'fess up to them. Those who don't will get moved to the "bad actor" category: and, yes, I am looking at you, Marvin Goodfriend.
The only remaining question, I think, is whether these should all be read in chronological or reverse chronological order. I find myself torn, with arguments on both sides having force:
