Desperate times; desperate measures. After months of costly delay, the eurozone has come up with an enormous package of support for Greece. By bringing in the International Monetary Fund, at Germany's behest, it has obtained some additional resources and a better programme. But is it going to work? Alas, I have huge doubts.

So what is the programme? In outline, it is a package of €110bn (equivalent to slightly more than a third of Greece's outstanding debt), €30bn of which will come from the IMF (far more than normally permitted) and the rest from the eurozone. This would be enough to take Greece out of the market, if necessary, for more than two years. In return, Greece has promised a fiscal consolidation of 11 per cent of gross domestic product over three years, on top of the measures taken earlier, with the aim of reaching a 3 per cent deficit by 2014, down from 13.6 per cent in 2009. Government spending measures are to yield savings of 5? per cent of GDP over three years: pensions and wages will be reduced, and then frozen for three years, with payment of seasonal bonuses abolished. Tax measures are to yield 4 per cent of GDP. Even so, public debt is forecast to peak at 150 per cent of GDP.

In important respects, the programme is far less unrealistic than its intra-European predecessor. Gone is the fantasy that there would be a mild economic contraction this year, followed by a return to steady growth. The new programme apparently envisages a cumulative decline in GDP of about 8 per cent, though such forecasts are, of course, highly uncertain. Similarly, the old plan was founded on the assumption that Greece could slash its budget deficit to less than 3 per cent of GDP by the end of 2012. The new plan sets 2014 as the target year.
