The EMU is not in danger

I have read many articles lately about how the PIGS of the Eurozone (Portugal, Italy, Greece, Spain) plus Ireland undermine the strength of the EMU and I have detected a somewhat slightly unwarranted prejudice against the economies of the countries of the European periphery. Fiscal irresponsibility is a reality in those countries indeed, but there is no need to single them out during this crisis, as Barry Eichengreen demonstrates very powerfully:

But the more days pass, the more it becomes evident that the truly big event is the negative economic shock affecting the entire euro area. Different euro area members may have felt financial disturbances to a different extent, but they are all now experiencing the economic disturbance in the same way – they are all seeing growth collapse. Germany, which thought itself immune from the economic crisis, is now seeing its exports slump and unemployment rise. The rise in unemployment may be small so far, but it is the tip of the iceberg. And there is no longer any doubt about how much ice lies just below the surface.

This shock is symmetric – it is affecting all euro area members. In turn this means that a common monetary policy response is appropriate. There will now be mounting pressure for the ECB to cut interest rates to zero, move to quantitative easing, and allow the euro exchange rate to weaken. (This last part of the adjustment is already beginning to happen without the ECB having to do anything about it.) Now that recession and deflation loom across the euro area, this is a response on which all members should be able to agree. It can be complemented by fiscal stimulus. If countries in a relatively strong budgetary position, like Germany, are in the best position to apply it, all the better; the result will be help from outside for their more heavily indebted, cash-strapped neighbours who need it most.
