The single most powerful argument for granting an extension to France and Italy

Confusion in Brussels, Francesco Saraceno

"To summarize it, here is what it says:

1. A recession triggers a reduction of the potential growth rate  (the maximum rate at which the economy can grow without overheating) because ofhysteresis: unemployed workers lose skills and/or exit the labour market, and firms scrap productive processes and postpone investment. I would add to this that hysteresis is non linear: the effect, for example on labour market participation, of a slowdown, is much larger if it happens at the fifth year of the crisis than at the first one.
2. According to the Commission’s own estimates Italy’s potential growth rate dropped from 1.4% on average in the 15 years prior to the crisis (very low for even European standards), to an average of -0.2% between 2008 and 2013. A very large drop indeed.
3. (Here it becomes interesting). The box in the Italian plan argues that we have two possible cases:
   1. Either the extent of the drop is over-estimated, most probably as the result of the statistical techniques the Commission uses to estimate the potential. But, if potential growth is larger than estimated, then the output gap, the difference between actual and potential growth is also larger.
   2. As an alternative, the estimated drop is correct, but this means that Italy there is a huge hysteresis effect. A recession is not only, as we can see every day, costly in the short run; but, even more worryingly, it quickly disrupts the economic structure of the country, thus hampering its capacity to grow in the medium and long run.

The box does not say it explicitly (it remains an official government document after all), but the conclusion is obvious: either way the Commission had it wrong. If case A is true, then the stagnation we observed in the past few years was not structural but cyclical. This means that the Italian deficit was mainly cyclical (due to the large output gap), and as such did (and does) not need to be curbed. The best way to reabsorb cyclical deficit is to restart growth, through temporary support to aggregate demand. If case B is true, then insisting on fiscal consolidation since 2011 was borderline criminal. When a crisis risks quickly disrupting the long run potential of the economy, then it is a duty of the government to do whatever it takes to fight, in order to avoid that it becomes structural."

I'm sure Commission economists know that, but their bosses?
