And his nervousness about that statement matches mine...
He notes that if the past decade has taught [him] anything, it has taught [him] that mistakes are avoided if you follow two rules:
- Remember that Paul Krugman is right.
- If your analysis leads you to conclude that Paul Krugman is wrong, refer to rule #1.
I have a similar view of the quality of Paul Krugman - and I am equally nervous saying he is wrong.
Nonetheless I formed the view that he was mistaken about five or six weeks ago... and posted it here and here and here and here and here and here and in a few other places.
I asked Paul Krugman for an email - because I am sure we could identify where we differ very accurately with an email exchange. No such luck.
