De Martin Wolf no FT (via Pedro Lains) do qual cito a conclusão nada optimista:
"Where does that leave peripheral countries today? In structural recession, is the answer. At some point, they have to slash fiscal deficits. Without monetary or exchange rate offsets, that seems sure to worsen the recession already caused by the collapse in their bubble-fuelled private spending. Worse, in the boom
years, these countries lost competitiveness within the eurozone. That was also inherent in the system. The interest rates set by the European Central Bank, aimed at balancing supply and demand in the zone, were too low for bubble-fuelled countries. With inflation in sectors producing non-tradeables relatively high, real interest rates were also relatively low in these countries. A loss of external competitiveness and strong domestic demand expanded external deficits.
These generated the demand needed by core countries with excess capacity. To add insult to injury, since the core country is highly competitive globally and the eurozone has a robust external position and a sound currency, the euro itself has soared in value.
This leaves peripheral countries in a trap: they cannot readily generate an external surplus; they cannot easily restart private sector borrowing; and they cannot easily sustain present fiscal deficits. Mass emigration would be a possibility, but surely not a recommendation. Mass immigration of wealthy foreigners, to live in now-cheap properties, would be far better. Yet, at worst, a lengthy slump might be needed to grind out a reduction in nominal prices and wages. Ireland seems to have accepted such a future. Spain and Greece have not. Moreover, the affected country would also suffer debt deflation: with falling nominal prices and wages, the real burden of debt denominated in euros will rise. A wave of defaults – private and even public – threaten."
