Drawing on a recent paper by Nouriel Roubini, Martin Wolf lays out the options facing the euro zone with depressing clarity. [...]
Mr Roubini discusses four options for addressing these stock and flow challenges simultaneously: first, restoration of growth and competitiveness through aggressive monetary easing, a weaker euro and stimulatory policies in the core, while the periphery undertakes austerity and reform; second, a deflationary adjustment in the periphery alone, together with structural reforms, to force down nominal wages; third, permanent financing by the core of an uncompetitive periphery; and, fourth, widespread debt restructuring and partial break-up of the eurozone. The first could achieve adjustment, without much default. The second would fail to achieve flow adjustment in time and so is likely to morph into the fourth. The third would avoid both stock and flow adjustment in the periphery, but threaten insolvency in the core. The fourth would simply be the end.
