Le Wall Street Journal démonte le "multiplicateur" keynésien en une formule lapidaire:
While he's in the U.K., perhaps Mr. Geithner should also ask his European counterparts whether any of them have ever seen a 1.5 Keynesian "multiplier" in the wild. That's the idea -- promoted by Mr. Summers -- that every $1 of deficit spending yields $1.5 in economic growth. If that were true, Italy would be the richest country in Europe, instead of merely one of the most indebted.
