As one European country after another finds its access to bond markets blocked, hopes are rising that the developing world might step in and relieve the crisis by buying the bonds that European investors and official entities are unwilling or unable to buy. And why not? The Brics alone have more than $4,000bn in reserves between them. This can fund a lot of deficits.
But more foreign investment will not help Europe – and may make things worse. National governments, it turns out, are suffering from skewed incentives, so that actions benefiting individual countries in the short term may hurt Europe as a whole. If many governments take such action, everyone is worse off.
It would seem that a country struggling to fund itself at manageable interest rates should welcome any big new investor, no matter what his provenance, as a valuable resource.
