When Greece was bailed out by a joint eurozone-IMF rescue package back in May, it was clear that the deal had bought only a temporary respite. Now the other shoe has dropped. With Ireland’s troubles threatening to spill over to Portugal, Spain and even Italy, it is time to rethink the viability of Europe’s currency union. These words do not come easily, as I am no Euroskeptic. Unlike others, such as my Harvard colleague Martin Feldstein, who argue that Europe is not a natural monetary area, I believed that monetary union made perfect sense in the context of a broader European project that emphasized - as it still does - political institution-building alongside economic integration.
