Krugman has shot back at David Stockman in his NYT blog today:

[CTyankee]

16. Stockman was never trained in Economics. At Harvard he studied social sciences and

then went on the Harvard's Divinity School, thinking he would be some sort of theological philosopher, but he lost interest there, too and went into politics.

As you can see in this brief piece, Krugman rather politely but pointedly made clear that Stockman didn't measure up with his reference to Stockman's lack of any models or data studies, the type of stuff Krugman does all the time, like any working economist. Business Insider calls Krugman's piece as "brief but brutal."

I don't know if Stockman really cares very much or cares too much. He may be "teched" as Krugman puts it...
