I'm pleased to hear that Paul Krugman does not like shallowness, particularly in the blogosphere. My guess is that most people would have a hard time putting his post into context, but I think he wrote it as a reply to my last post. Follow the "pulling rank" link in his last paragraph. Too bad that Krugman went shallow on this one. It would be much more interesting if he actually addressed the issues.
As an update on John Quiggin and Zombie Economics, (which initially set Krugman off on his "pulling rank" nonsense), if you have not read my longer critique of Quiggin's book, it is published in the Australian National University E Press. The paper is not just about Quiggin's book. It also serves as a response to the people who think that all of modern macroeconomics needs to go out the window because the financial crisis happened. Apparently Quiggin seems bothered by my critique, though he does not address the substance. It seems he would be happier if it had been written by an Australian, and not just another colonial.
