In his latest New York Times article (December 10, 2009) – Bernanke’s Unfinished Mission – Paul Krugman reveals that he doesn’t really understand much about macroeconomics. Sometimes you read a columnist and try to find extra meaning that is not in the words to give them the benefit of the doubt. At times, Krugman like other columnists sounds positively reasonable and advances arguments that are consistent with modern monetary theory (MMT). But then there is always a give-away article that appears eventually that makes it clear – this analyst really doesn’t get it. In Krugman’s case, he doesn’t seem to have learned from his disastrous foray into Japan’s “lost decade” policy debate.
