A battle has erupted between conservatives and progressives
and Krugman is basking in glory. An academic paper widely cited by
conservatives and the mainstream press that claimed high debt leads to lower
growth (which directly contradicts the solutions Krugman puts forth) is getting
a lot of bad press for errors. Previously he has written about issues with the
paper so now that it is getting slammed he is doing a victory lap. There was an
even a news article in the WSJ citing the controversy.
