ITo wit: the four academics who filed a suit against Germany joining the euro, and lost, are now, despite the on/off/on bailout, publicly clamoring for a Greek exit from the euro, and a 40% deval for a new Drachma.
The figure of 40% puts a level on the extent of the Greek problem.
Assuming these economists have got their maths right (and in fact I don't think it is that hard a calculation, so they probably have) this is jaw-droppingly shocking. Greece joined the Euro in 2001. Had they remained on the drachma it would have devalued by 40% over 9 years (against the Euro), or ballpark 4% pa. I haven't hunted for figures, but this is pretty much the norm for Club Med currencies (falling say against the DM, often by more than this) prior to joining the Euro. It is actually perfectly credible that this has happened. But the logic of the Euro is that it shouldn't have happened.
The German economy needs some form of currency revaluation. The figure I've heard is around 20%. The difference between Germany and Greece is therefore something like 60%.
These issues are beyond resolution by adjusting the internal fiscal policies of the countries of the EU. You cannot solve an overvaluation of your currency of anything like this magnitude by austerity alone. Curiously even the idea of the northern countries breaking away with their own currency doesn't solve a problem as extreme as that of Greece. Nor does subsidy from the north work - the subsidies would have to be so enormous and for so long.
The "solution" we have in place is the muddled bailout plan - which means no Eurozone state will ever be allowed to fail, and which requires a European economic government. But such an economic government needs a treaty of the 27 and will take ages. The Euro doesn't have this long. I don't doubt that many politicians would like an economic government, but they can't deliver, and we are going to see the IMF bailing out one or more Eurozone countries within a few months, before such a plan is even off the drawing board.
Of course the European financial boffins will have a plan up their sleeve, and they are not going to chatter about it in advance. There is some talk if you look hard enough about the possible issue of bonds as a de facto second currency (see posts above). Thinking today about the extent of the Greek problem and the realisation that others are not far behind I'm wondering if the solution that will be proposed is issuing such national bonds in
all Eurozone countries while keeping the Euro. They would be presented as a temporary measure until economic government is established. While filling most of the roles of a currency they would not technically be currencies, and the idea would be that they are fazed out and the Euro resurfaces. It would be a Eurocratic solution!
Politically this has the potential to run during the UK election. If the EU is now proposing a new "economic government" treaty - the next treaty after Lisbon - Cameron has already pledged a referendum on such a treaty, while Brown has said "economic governance" was his idea. I think Cameron could coherently argue that Conservatives would oppose further transfer of power to the EU. He could also argue that the need for a new treaty shows that Lisbon is deeply flawed and must be modified. He could even argue that when a new treaty is presented the UK would be given a multi-option referendum including leaving the EU. I think in this he has the issue he needs to grab the UKIP vote, and that as far as Cameron is concerned it is just a case of hoping the EU "economic government" story hots up in time. He needs 44% for a comfortable win, might scrape in with 41%, is presently on maybe 37%-39%. UKIP polled 12% in the last EU election and are likely to get around 6% at the General Election. If he could pinch this 6% he would be smiling. And I don't see how he can not try.
