IN RECENT months many economists and policymakers, including such unlikely bedfellows as Paul Krugman, an economist and New York Times columnist, and Hank Paulson, a former American treasury secretary, have put “global imbalances”—the huge current-account surpluses run by countries like China, alongside America’s huge deficit—at the root of the financial crisis.
But the IMF disagrees. It argues, in new papers released on Friday March 6th, that the “main culprit” was deficient regulation of the financial system, together with a failure of market discipline.
