SPIEGEL: Mr. Sinn, Chancellor Angela Merkel feels as though economists have left her in the lurch. She once said that the advice that she receives from economists is "about as diverse as it gets." Can you see where she is coming from?
SPIEGEL: Excuse me? Economists have completely different ideas about how the euro can be saved. You suggest, for example, that countries should temporarily leave the euro zone until they have re-established their competitiveness. Others, by contrast, recommend collectivizing debt across the euro zone. How should politicians deal with such contradictory advice?
Sinn: There are differences in the recommended therapies, but fewer divergences in the analysis. There is considerable agreement today on the euro's defects.
SPIEGEL: But not on how the euro can be saved, or even whether it should be.
