Policy leaders in Europe pushed austerity measures last year for EU nations with high levels of debt. Now, as growth has flattened on the continent, some are concerned that austerity is a weight on GDP. Daniel Gros , Director of the Center for European Studies, isn't buying that argument. At Project Syndicate , Gros writes that a drop in government expenditures does not spell a significant enough slowing of economic activity to have a long term negative effect. Gros: In Europe, the concern today is instead with the debt/GDP ratio. The worry here is that the GDP drop resulting from “austerity” might be so large that the debt ratio increases. This matters, because investors often use the debt ratio as an indicator of financial sustainability. Thus, a lower deficit might actually heighten tensions in financial markets. However, a lower deficit must lead over time to a lower debt ratio, even if this ratio worsens in the short run. After all, most models used to assess the economic impact of fiscal policy imply that a cut in expenditure, for example, lowers demand in the short run, but that the economy recovers after a while to its previous level. So, in the long run, fiscal policy has no lasting impact (or only a very small one) on output. This implies that whatever short-run negative impact lower demand may have on the debt ratio should be offset later (in the medium to long run) by the rebound in demand that brings the economy back to its previous output level. Moreover, even assuming that the impact of a permanent cut in public expenditure on demand and output is also permanent, the GDP reduction remains a one-off phenomenon, whereas the lower deficit continues to have a positive impact on the debt level year after year.
