By the way, Greece is still a mess

The other half of the chief economists, like me, recognised that a single currency would be introduced, no matter how nonsensical the economics, since it was a political project. (The economics being bad, the politics was even worse: the end of democracy in Europe). They agreed with me that it was going to be a disaster.

Consider first the 1990s. Like many economists, at the time I pointed out that the plans by the eurocrats to introduce a single currency were thoroughly misguided: monetary policy is the most powerful policy arm, and there is no reason why any government should amputate it. As I argued then, historically the German D-Mark had been strengthening since its introduction in 1948 against the currencies of its neighbours, and this reflected – and compensated for – increased German competitiveness. Their weakening currencies allowed German trade partners to keep their export industries in business and their workers employed. By introducing a single currency, future revaluations of the German currency were disallowed. This amounted to a de facto future devaluation of German purchasing power, revaluation of the currencies of the other European countries, and hence would render non-German economies less and less able to compete against German exports over time.

To economists – even of the mainstream ilk – it was clear what would have to follow: Unable to depreciate their currencies, countries such as Spain, Italy, let alone Greece would need to conduct what is euphemistically called an ‚internal devaluation‘, i.e. wages would have to fall significantly and domestic purchasing power would have to be reduced. Countries refusing to implement such austerity policies or trying to circumvent them would face ballooning trade deficits with Germany and the need for ever greater borrowing from the German central bank (via what came to be known as TARGET2). Their debt would swell, until reaching an unsustainably high level, and then something drastic would have to happen – default, exit from the single currency, or both. It was an almost unique instance where most economists – famous for disagreeing – agreed.
