Greece needs to leave the euro: Part I

I wrote this comment in reply to a great article published by Martin Wolf in the FT today (6/3/2015) which you can find here

Good article, but in my humble opinion some misconceptions.  

First, Martin Wolf makes the point that the euro area is not an OCA.  As my research has clearly shown (see my Bank of Finland discussion paper on this issue published 2 years ago  http://www.suomenpankki.fi/en/julkaisut/tutkimukset/keskustelualoitteet/Pages/dp2013_33.aspx), Greece does not have, and never did have, business cycles (or any other cycles for that matter) that are synchronous with the rest of the euro area.  It is simply not a good fit with the rest of the euro area, without (according to the OCA theory) there being sizable offsets which consist of fiscal transfers and much higher labor mobility.  And this is the case both ex-ante, and ex-post.  So, given this empirically proven stylized fact:

Second, the Greek government is simply wasting it's time and energy negotiating something that will not result in any long term membership of the euro - it will just be "another shot of medicine to help the dying patient".  I understand that the fact that the Greek government is actually negotiating is a necessary political pre-requisite to leaving the euro, but let's not drag this sorry Greek tragedy on any further than needs be, as this just prolongs and likely exacerbates the suffering of the Greek people.  

Third, Martin Wolf says that this will have a profound effect on the euro area and reverse the integration dynamic.  Well, hmmm, Greece is a little country the size of the State of Rhode Island in the context of the US - so it's not as if Spain or Italy were leaving. The euro area is 16 years old - and so its longevity won't depend on one small member deciding to leave early on it's evolution.  Also, the UK leaving the EU would have a much bigger impact on the integration dynamic than Greece leaving the euro area. 

Lastly, Wolf clearly wants Greece to stay inside the euro when he says that "This must be seen as a long game".  I mean how long do you want this game to be?  Governments simply don't think long term as their time horizons are short term or medium term at best. So the Syriza government really has the choice of alienating it's supporters and signing up to something that it promised never to sign up to, or pulling Greece out of the euro, which will create some chaos to begin with unless they have a proper plan B in place.  

If I were the Greek finance minister right now (which thankfully I am not), I would be furiously planning and comparing different strategies for a euro exit, as inevitably, that's what is the most likely outcome here.

Now in part 2 of this blog, which will come out in the next couple of days, I will outline what I think the options are for Grexit.
