Barley points out that the Euro-zone austerity plans in Greece, Ireland, Portugal, Spain, the U.K. and other countries are coming in the context of a potential global slowdown. This will make it even harder for these countries to reduce debt and deficits. Greece had to make cuts and tax increases equivalent to 8% of GDP just to reduce the 2010 deficit by 5% after GDP declined more than expected according to the IMF. To reduce debt ratios nominal growth has to be higher than the average interest rate on debt. Its hard to see this happening and debt not increasing in some Eurozone countries.
