The other side is whether the single currency project was itself unviable given that those who joined are sovereign nations. (We in India have seen how difficult it is to have a “common market” in the sense of a single goods and services tax even in a single country, despite states not being “sovereign”.) Many economists are questioning the viability of the single currency project in the absence of a federal structure.
In an article in Le Monde last month, Cedric Durand and Sebastien Villemot, members of the European Research Network on Social and Economic Policy, commented that “no European sovereign, no real budget: no budget, no viable economic policy… If a budgetary federation is out of reach, it is crucial that we can adjust exchange rates in order to give dynamism to growth and employment. And this requires leaving the currency union”. In The Euro and the Battle of Ideas, Markus Brunnermeier, Harold James and Jean-Pierre Landau have criticised euro zone governments for not realising that their euro-denominated public debts are in effect denominated in a foreign currency — and they have no lender of last resort with a supranational central bank. In a Project Syndicate column, George Soros has argued that, after the sovereign debt crisis of 2008, “Germany emerged as the hegemonic power in Europe” and “the EU and the euro zone became increasingly dysfunctional”. (Incidentally, Soros had made a billion when the pound was forced out of the exchange rate mechanism in 1992.) Joseph Stiglitz, in an article in the Financial Times (August 17, 2016), advocates a two-euro solution: “A strong Northern Euro and softer Southern Euro. Of course, none of this will be easy. The hardest problem will be dealing with the legacy of debt. The easiest way of doing that is to redenominate all euro debts as ‘southern euro’ debts”. Dani Rodrik, in a Project Syndicate column, believes that “either political integration catches up with economic integration, or economic integration needs to be scaled back. As long as this decision is evaded, the EU will remain dysfunctional”.
