He’s not a Nobel Prize winner. He got the Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel which is awarded by the Swedish Central Bank in Nobel’s honor but doesn’t have anything more with the actual Nobel prizes to do than that the winner gets to sit at the same table as the actual Nobel winners. Also, economic “sciences” is about as scientific as astrology, and Krugman in particular is at the bottom of the barrel among those in that mumbo-jumbo field.
My point is, he’s an idiot and nobody should care what he says, unless they’re looking to be entertained at his expense.
That’s handy info
