For some, the fiscal problems in the US and Europe are a case of bad politics getting in the way of good economics. This column argues that there was plenty of bad economics as well. It looks at the work of the two recent Nobel Laureates in offering some clear thinking.


The US and the EU, the most powerful economic areas in the world, are bedevilled by seemingly intractable fiscal problems. Their problems stem from a variety of sources; inconsistent promises of low taxes and high benefits, creative accounting, and financial bailouts have all contributed to mounting government debts, with no end in sight.

This year’s Nobel Prize in economics went to two economists who years ago laid out the bracing logic of government finance. Thomas Sargent is famous among economists for many things, but among them is “Some Unpleasant Monetarist Arithmetic,” a paper he wrote with Neil Wallace in 1981. His distinguished Nobel partner Christopher Sims is known partly for a 1994 paper “A Fiscal Theory of The Price Level” that connected the price level to fiscal policy. Both papers focus on the government budget constraint – the unavoidable connection between deficits, debt, and inflation.
