We know that rising unemployment is not something that will make the EU admit that their current macroeconomic policy mix isn’t working.
We know that two successive years of GDP contraction is not something that will make them admit it either. Even though some of them denied at the time that this could be a consequence of austerity.
Will spiralling debt/GDP ratios do the trick? This is, after all, the number they have been fixated on since 2010, and the figures show that, even on its own terms, the current strategy has not been working.
This is where dodgy GDP forecasting becomes so pernicious: no matter how much of a basket case the Eurozone becomes, over-optimistic forecasts — notice how good we expect 2014 will be!! — will always make it possible for discredited politicians, central bankers and eurocrats to cling on to the hope that good times are just around the corner. The risk is that they will wake up one day and find that it is too late to change course, both for themselves and for the euro.
