The international debate on the wisdom of fiscal austerity has being heating up. Since the onset of the crisis, the consensus seems to have gone through different stages: initially there was widespread support for fiscal stimulus, followed by concerns that fiscal policy needed to tighten as debt to GDP ratios rose in many countries to worrying levels, followed more recently by concern that fiscal policies may tighten too much given the persistence of the crisis-induced recessions.
A useful aspect of the recent debate is greater differentiation between countries facing serious sovereign creditworthiness challenges and those that do not. Countries facing immediate creditworthiness problems face a dilemma: fiscal tightening tends to further weaken the real economy; but allowing deficits and debt to stay on a higher path further weakens creditworthiness. The fiscal council has been grappling with this dilemma in its first two reports (see here and here).
Drawing on recent work with a number of co-authors, Giancarlo Corsetti provides a useful framework in this VOX piece for thinking about the dilemma. He makes the important point that the appropriate fiscal stance can be quite different for countries facing a large market risk premium (e.g. Ireland) and those that don’t (e.g. the UK). Countries facing a large risk premium face a dilemma in setting the fiscal stance between supporting demand and supporting creditworthiness – a trade off that is absent or at least much less pronounced in countries with low long-term bond yields. Corsetti’s framework has the additional element that increases in the sovereign risk premium can feed through to the risk premium facing the private sector though the entwining of bank and sovereign balance sheets. While he does not believe that this additional element makes fiscal contractions expansionary, it does tend to reduce fiscal multipliers. On the other hand, for countries not facing an elevated risk premium, multipliers are likely to be large for countries in deep recessions with policy interest rates constrained by the zero lower bound, suggesting the appropriateness of a more stimulative fiscal stance.
