This paper investigates the impact of fiscal consolidation on economic growth in European Union countries, between 2004 and 2013. We construct a new dataset of exogenous fiscal adjustments, relying on legally binding recommendations issued to countries under Excessive Deficit Procedure, and we identify exogenous policy changes by using this dataset as instrumental variable in a GMM framework. We estimate the size of the fiscal multiplier both in a linear setting as well as in a state-dependent setting, considering four different circumstances: the state of the business cycle, the degree of openness to trade, the composition of the fiscal adjustment and the presence of a stressed credit market, as manifested by an impaired monetary policy transmission. We find that the size of the multiplier varies significantly under the various states: the distribution of multipliers is quite asymmetric, and a few consolidation episodes yield multipliers above one. We find that the composition of the fiscal adjustments is crucial in containing the output cost of consolidation, and in determining its persistence. Fiscal adjustments made via cuts to transfers and subsidies, or via tax increases, are usually associated with multipliers at or below unity, even when the economy is in recession. We also find evidence of confidence effects when consolidation is made under stressed credit markets and high interest rates. In a small number of episodes, involving open economies benefitting from confidence effects, we find that fiscal adjustments seem to be expansionary.

Résumé Nous étudions l'impact de la dette publique sur la croissance du pib par tête depuis 1970 et sur une période d'environ quarante années. L'impact de la dette sur la croissance est décrit par une relation non linéaire avec un seuil de l'ordre de 90-100% du pib au-delà duquel le ratio de la dette a un effet négatif sur le pib . Les intervalles de confiance montrent que des effets négatifs peuvent se manifester dès que le ratio de la dette devient égal à 70-80%, ce qui implique que la politique d'endettement doit devenir même plus prudente. Notre résultat est un argument supplémentaire en faveur des politiques de réduction de la dette comme une politique de soutien de la croissance à long terme. JEL Code : H63, O40, E62

This paper investigates the average impact of government debt on per-capita GDP growth in twelve euro area countries over a period of about 40 years starting in 1970. It finds a non-linear impact of debt on growth with a turning point—beyond which the government debt-to-GDP ratio has a deleterious impact on long-term growth—at about 90-100% of GDP. Confidence intervals for the debt turning point suggest that the negative growth effect of high debt may start already from levels of around 70-80% of GDP, which calls for even more prudent indebtedness policies. At the same time, there is evidence that the annual change of the public debt ratio and the budget deficit-to-GDP ratio are negatively and linearly associated with per-capita GDP growth. The channels through which government debt (level or change) is found to have an impact on the economic growth rate are: (i) private saving; (ii) public investment; (iii) total factor productivity (TFP) and (iv) sovereign long-term nominal and real interest rates. From a policy perspective, the results provide additional arguments for debt reduction to support longer-term economic growth prospects.

The financial crisis of 2008/2009 has left European economies with a sizeable public debt stock bringing back the question what factors help to reduce these fiscal imbalances. Using data for the period 1985-2009 this paper identifies factors determining major public debt reductions. On average, the total debt reduction per country amounted to almost 37 percentage points of GDP. We estimate several specifications of a logistic probability model. Our findings suggest that, first, major debt reductions are mainly driven by decisive and lasting (rather than timid and short-lived) fiscal consolidation efforts focused on reducing government expenditure, in particular, cuts in social benefits and public wages. Second, robust real GDP growth also increases the likelihood of a major debt reduction because it helps countries to "grow their way out" of indebtedness. Third, high debt servicing costs play a disciplinary role strengthened by market forces and require governments to set up credible plans to stop and reverse the increasing debt ratios.

This paper looks at fiscal sustainability and fiscal risks from a comprehensive, global perspective. It argues that the benefits of consolidation have to be re-assessed given that industrialised countries have entered uncharted waters with unsustainable public debt dynamics and enormous contingent liabilities across sectors and countries coinciding with strong, non-linear and potentially highly adverse fiscal-financial interlinkages. This suggests that there would be significant benefits from fiscal consolidation without delay and that there is a need for caution against excessive faith in fiscal engineering.

In this paper we study the determinants of sovereign debt credit ratings using rating notations from the three main international rating agencies, for the period 1995-2005. We employ panel estimation and random effects ordered probit approaches to assess the explanatory power of several macroeconomic and public governance variables. Our results point to a good performance of the estimated models, across agencies and across the time dimension, as well as a good overall prediction power. Relevant explanatory variables for a country's credit rating are: GDP per capita, GDP growth, government debt, government effectiveness indicators, external debt, external reserves, and default history.
