The Greek government has demonstrated that it can still borrow at a rate of about 6 per cent but if you do the maths on the public debt dynamics, as I did recently, it would be hard to arrive at any other scenario than an eventual default.
The adjustment effort needed to prevent a debt explosion is extremely large. The Nordic countries achieved adjustment on a similar scale during the 1980s and 1990s, but they had two advantages over Greece. They did it in a different global environment; but more crucially they were, in part, able to devalue and improve their competitiveness. As a member of a large monetary union Greece can improve its competitiveness only through relative disinflation against the eurozone average, which in effect means through deflation. But as the French economist Jacques Delpla* has pointed out, this will invariably produce a debt-deflation dynamic in the Greek private sector of the kind described by the economist Irving Fisher during the 1930s.
