This just couldn't me more false. Krugman's whole career is built around big government manipulating the money supply.
and he knows his economics
Lots of people who also "know their economics" disagree with Krugman. Economics, as a field, hasn't risen to the level of a science yet.
Krugman's a vaguely center-left one
That's precisely what I meant by "built around big government manipulating the money supply"
As for partisan: I think all economists that take a definite position fall under what I meant by "partisan." I meant: advocating a niche view that is not accepted by a majority of experts. (In economics, I don't think there is currently any view that doesn't fall under this description.) That's not to say there isn't a correct view; I think there is.
