The wacky economics of Germany’s parallel universe

German economists roughly fall into two groups: those that have not read Keynes, and those that have not understood Keynes.

.. For example, German ordoliberals simply refuse to acknowledge the presence of a liquidity trap where the central bank becomes powerless in affecting market interest rates. Ludwig Erhard, Germany’s revered economics minister in the 1950s, once tried to explain the Great Depression in terms of cartels. It was an ordoliberal attempt to bring something into their mental framework for which they have no obvious explanations. Erhard’s successors repeated the mistake in the eurozone crisis, which they see as a story of fiscal indiscipline.

.. Through its dominance of the euro system, Germany is exporting ordoliberal ideology to the rest of the single currency bloc. It is hard to think of a doctrine that is more ill suited to a monetary union with such diverse legal traditions, political system and economic conditions than this one. And it is equally hard to see Germany ever giving up on this. As a result the economic costs of crisis resolution will be extremely large.
