The Economist published a very lucid analysis (link) of the recent macroeconomic instability in the Euroarea, following the outbreak of Greek debt crisis (link) and disappointing quarterly data on GDP growth (link):
Barely had the ink dried on a statement by European leaders supporting Greece in its struggle to finance its debts when more bad news emerged from the euro zone. Figures released on Friday February 12th showed that GDP in the 16-country currency zone rose by just 0.1% in the three months to the end of December compared with the previous quarter. That there was any improvement at all was largely down to France, where a burst of consumer spending lifted the economy by 0.6%. In the region’s other big countries, GDP was either flat—as in Germany—or falling, as in Italy and Spain.
