True - PSCANDIZZO, and further to that internal devaluation will have an effect on the labour market which may hurt tradables as highly skilled workers emigrate and immigrants return home, either through shortage of work and/or increased hostility towards immigrants (witness the PIIGS).
As for the EU Treaty / Austerity Measures it appears that there is a similar position in Greece as in Ireland. I've been in Crete for the past week, including election day, and there appears to be serious pressure for the country to accept the bailout medicine on the roadside and in the press, to the extent that it is presumed that not accepting the terms of the bailout equates with exiting the Euro. However, the people have spoken and pro-austerity parties have ended up in the minority - a seismic change in Greek politics (possibly an indication of what will happen to the treaty vote in Ireland?) . For sure, no party can form a government (the left would not entertain a coalition with the far right anti-austerity party), but the predictions are that the inevitable election later this year will strengthen the anti-austerity parties even more.
Together with France's rejection of austerity this week (or was it just rejection of Sarkozy?), it appears that we are seeing a shift in the European response to the crisis. Increases in German wages may be the first expansionary signs from the heart of Europe but surely there are more to come. It appears that Hollande has rejected calls for a meeting with the Greek left, but now that the anti-austerity cat is out of the bag it will be interesting to see how the EU institutions deal with it.
Already this week Olli Rehn, the commissioner tasked with dealing with the euro crisis, has stated "We are seizing the moment to advance our proposals in the new political climate", and was backed by the EC's President, Barroso, to increase the capital of the EIB by €10 billion next month, presumably to secure large infrastructure projects. Another €82 billion of unused structural funds could also be used in an expansionary way. Finally, Rehn indicated that fiscal conditions may be loosened (though not for Greece!!).
