My 2 cents on Greece: The root of all evil was not having a credible no-bailout cost.
The root of all evil. Markets believed (and rightly so) that if a euro area Member State ever got into serious trouble it would be bailed out by the other Member States, this is the only way countries with such different fundamentals as Germany and Greece were paying almost the same 4 percent interest rate on their sovereign debts before the crisis. Greece was living above its means, as pointed out by many and had to tighten its belt, back to reality, indeed.
The second blunder was to chicken out from financial contagion and to bailout the private lenders. The 2010 bailout was in effect, not a bailout of the debtor but of the creditors: private debt was replaced by official debt, i.e. save the banks with taxpayers money, yes the markets were absolutely right in pricing German and Greek as equally good, it was the Eurozone after all. It was not a market failure as some like to think, but a government failure (as usual, or as I choose to believe). Had they built a credible no bailout clause banks and other private creditors would have never lent Greece so much money at such low rates and the previous Greek governments would have never been able to pile up so much debt in the first place. A credible no-bailout clause would say something like: you may run deficits as large as you want, but if you can’t pay your bills that’s your business, you’re on your own. Instead they constructed non credible fiscal rules that everybody (beginning with Germany and France) violated anyway, since the fines for violation were not a credible threat.
So fine, by 2010, they had already messed it up. What do you do with a debtor who can’t afford his/her bills, you incarcerate him/her? That was the usual practice in Medieval Europe. Nowadays though, the International Covenant on Civil and Political Rights says: "No one shall be imprisoned merely on the ground of inability to fulfill a contractual obligation." There are bankruptcy laws, and there are sovereign defaults too (though no system for orderly sovereign defaults exists, as proposed by the IMF because big creditors lobby against such thing). So came the third blunder: instead of restructuring the unsustainable debt as the IMF wanted and they now publicly acknowledge (IMF: "Earlier debt restructuring could have eased the burden of adjustment on Greece and contributed to a less dramatic contraction in output,"), they EU side convinced the IMF to do otherwise: no euro area country shall ever default or restructure its debt. They were obviously wrong and restructuring did happen 2 years later.
Now, most of the necessary market reforms to make Greece more productive and competitive were simply not carried out during the last 5 years, this is what Hausmann rightly points to. The previous Greek governments were just playing along in the EU’s kicking the can game. Oh, you’ll lend us even more money if we promise to be responsible good boys, as long as we commit to pay our unsustainable debt, which we know we won’t ever be able to pay, and we know you know we won’t be able to pay, cool!
So, why is a right libertarian like me supporting a far left government with communist roots (which would usually nauseate me). Because they’re defaulting, and that’s the only sensible thing to do, end this madness of incarcerating a debtor who is unable to pay back. This time, you (official creditors) have no mechanism to implement forced labor through which Greece will eventually pay you back, it ain’t happening, and you know it!
This economic mess has turn into a simple power struggle, do as I do or walk your way, so that all other Members see what happens when you’re a naughty boy. This is not the way you build up a credible no bailout rule guys, you are in effect bailing them out. Ultimately, if the referendum results in a majority of Yes votes, and a new government accepts to implement even more austerity, guess what? You’ll be bailing them out again, putting more money on the table that will never be repaid because they won’t grow like that!. It’s a lose-lose situation, debtor imprisoned with a debt which will never be redeemed.
Note: this was very roughly drafted in a rampage of inspiration that rarely materializes into any writing, so I'll be happy if you point out spelling/grammar mistakes, factual inaccuracies and most of all, constructive opinion comments.
