When it comes to inflicting pain on the citizens of debtor nations, austerians are all steely determination – hey, it’s a tough world, and hard choices have to be made. But when they or their friends come under criticism, suddenly it’s all empathy and hurt feelings.

We saw that in the case of Olli Rehn, whose friends at the European Commission were outraged, outraged when I pointed out, using slightly colorful language, that he was repeating an often-debunked claim about economic history. And today we see it in Anders Aslund’s defense of Reinhart and Rogoff against what he calls a “vicious” critique by Herndon et al.

Aslund praises R-R for providing

an important corrective to the view that fiscal stimulus is always right – a position that is common across the Anglo-American economic commentariat, led by Paul Krugman in the New York Times.

This is a curious thing for him to say, because it’s an outright lie; as anyone who has been reading me, Martin Wolf, Brad DeLong, Simon Wren-Lewis, etc. knows, our case has always been that fiscal stimulus is justified only when you’re up against the zero lower bound on interest rates. I can’t believe that Aslund doesn’t know this; why, then, would he discredit himself by repeating an easily refuted falsehood?

But then, why would he describe Herndon et al as “vicious”? Their paper was a calm, reasoned analysis of how R-R came up with the famous 90 percent threshold; it came as a body blow only because of the contrast between the acclaim R-R received and the indefensible nature of their analysis.

What I think is happening is that austerians have put themselves in a box. They threw themselves – and their personal reputations – completely behind the various elements of anti-Keynesian doctrine: expansionary austerity, critical debt thresholds, and so on. And as Wolfgang Munchau says, the terrible thing was that their policy ideas were actually implemented, with disastrous results; on top of which their intellectual heroes have turned out to have feet of clay, or maybe Silly Putty.

As I see it, the sheer enormity of their error makes it impossible for them to respond to criticism in any reasonable way. They have to lash out any way they can, whether it’s ad hominem attacks on the critics or bitter complaints about bad manners.

And by such pettiness the world is governed.
