Oh Scott, why do you vex me so? In the midst of an EconLog post, Scott had this throwaway line (in my bold):
I first got into blogging in 2009 out of frustration over Fed policy. The US obviously had a huge demand shortfall, and the Fed wasn’t doing enough to address the problem. Indeed I believe the Fed caused the huge demand shortfall.
So most people think I’m a demand-side economist. (Some even equate “demand-side” with “Keynesian,” which would make Milton Friedman roll over in his grave.)
Now follow me on this. In order for that parenthetical statement to make any sense whatsoever, surely both of the following statements must be true:
(1) Milton Friedman never said that his occasional focus on monetary aggregates could arguably qualify him as a Keynesian.
(2) Scott Sumner never referred to himself as a Keynesian.
And yet, Milton Friedman famously said there is a sense in which all (sic) economists were Keynesians because they rely on the Keynesian language and apparatus, and Scott once referred to himself as the last New Keynesian economist.
(That giant sucking sound you hear is the universe imploding.)
