Prescott has his Five Macroeconomic Myths. Sawicky offers The Five Boxes of Populist Economics. I sample an old exchange with Max -- in not one, not two, but three parts (at least) -- and try to make sense of it all at the Cleveland Fed's website. A small taste:
So is [GDP below its potential] today, and can monetary policy do anything about it? Sawicky says yes, Prescott says no. What say I? Two-handed economist that I am, I may not go all the way to Prescott’s view—but I lean in that direction.
You can read the whole thing here.
BELATED UPDATE: pgl at Angry Bear wants to be clear about this:
... a two-handed economist understands that productivity shocks exists AND knows that Keynes had a point in his 1936 General Theory.
Indeed.
