Several readers have asked me about fiscal rules and I have been promising to write about them for some time now. I was finally goaded into action by the current German rush to madness which will see them constitutionally outlaw deficits. When I saw the news that the German government was pushing constitutional change along these lines I thought good – the Eurozone will be dead soon enough and perhaps a better aligned fiscal and monetary system will emerge. Fiscal rules can take lots of different shapes all of which entrench chronic unemployment and poverty. The only fiscal approach that is applicable to a sovereign government operating within a fiat monetary system is one that ensures full employment is achieved and sustained. Anyway, here is an introduction to the mean-spirited and wrong-headed world of fiscal rules.
