Global economic policy

Austerity alarm

Both sides in the row over stimulus v austerity exaggerate, but the austerity lobby is the more dangerous

ECONOMIC policymaking, like hemlines, has fads. Last year the leaders of the G20 group of big economies led a global Keynesian boost, pledging fiscal stimulus worth a combined 2% of world GDP to prop up demand. At their most recent gathering, in Toronto on June 26th-27th, the club’s rich-world members pledged “at least” to halve their deficits by 2013. Though they left themselves wiggle room, the change of tone was clear. Thanks to Greece’s sovereign-debt crisis, which has terrified politicians, stimulus is out and deficit reduction is in.
