Why Does Stimulus Work? A Follow-Up

Just a quick note: a few days ago I linked to a John Cochrane post in which he suggested a big difference between the Old Keynesian and New Keynesian explanations for why fiscal stimulus works. Aside from any other disagreements that liberal economists might have with Cochrane, I was curious about whether his description was correct. Well, for those of you who have been sitting on the edges of your seats waiting for an answer, now we have one. Robert Waldmann (here) and Paul Krugman (here) basically say that Cochrane’s story is so fundamentally confused that it’s all but impossible to even criticize it. “Cochrane’s fantasy has so little connection with reality that it is hard to discuss,” says Waldmann. “He can’t be bothered to actually figure out how the models work,” says Krugman. So that’s that. No punches are being pulled in this cage match. Just thought I’d pass it along.

We've never been very good at being conservative.

And usually, that serves us well in doing the ambitious, hard-hitting journalism that you turn to Mother Jones for. But it also means we can't afford to come up short when it comes to scratching together the funds it takes to keep our team firing on all cylinders, and the truth is, we finished our budgeting cycle on June 30 about $100,000 short of our online goal.

This is no time to come up short. It's time to fight like hell, as our namesake would tell us to do, for a democracy where minority rule cannot impose an extreme agenda, where facts matter, and where accountability has a chance at the polls and in the press. If you value our reporting and you can right now, please help us dig out of the $100,000 hole we're starting our new budgeting cycle in with an always-needed and always-appreciated donation today.
