There is a significant amount of hand-wringing going on in the US that the Euro is fraying on the edges. Some pundits have even coined a rather derogatory acronym for Euro-countries in economic distress: the PIGS (Portugal, Italy or Ireland, Greece, Spain). The acronym bunches together four countries with very different backgrounds but one shared fact: they all face serious budget shortfalls, writes the Atlantic Review.

The grouping of these countries, largely by investment banks, may simplify investment and policymaking decisions to an unfortunate level. Italy for one does not want to be part of the group, and the Italian bank UniCredit has waged an effective campaign to change the “I” in PIGS to Ireland. But Ireland too has begun to restore both consumer confidence and budget stability thanks to aggressive action by the central government. Commentators seem to keep the “I” because that is the crucial vowel that holds the acronym together.

Portugal, Spain, and Greece are also all facing very different challenges. Portugal has a sizable but manageable budget deficit, while Spain is struggling with a burst housing bubble a la Florida. Greece remains the real country of concern; but then again, Greece has roughly the same debt levels as Germany, so what is all the fuss about?

The classification overlooks the more important–and legally binding—organizations already in existence, namely the EU and the Eurozone. Talk of the dissolution of the Euro is premature but rampant.

How should we classify countries economically? Is there any value in grouping problem areas? Just as a reference, I did a quick look at state budgets in the US and found five states with budget deficits greater than 10% in 2009: Arizona, California, Nevada, New Jersey, Rhode Island. Do you think CARINN could catch?
