The impact of high and growing government debt on economic growth: an empirical investigation for the euro area

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 role of fiscal transfers for regional economic convergence in Europe

This paper provides evidence on the role of net fiscal transfers to households and EU structural funds for per-capita output convergence across a large sample of European regions during the period 1995-2005. We find that net fiscal transfers, while achieving regional redistribution, seem to impede output growth and promote an “immiserising convergence”: output growth rates in poor receiving regions decline by less than in rich paying regions. EU structural and cohesion funds spent during 1994-1999 had a positive, but slight, impact on future economic growth, mainly through the human development component.

Labour tax progressivity and output volatility: evidence from OECD countries

This paper investigates empirically the effect of personal income tax progressivity on output volatility in a sample of OECD countries over the period 1982-2009. Our measure of tax progressivity is based on the difference between the marginal and the average income tax rate for the average production worker. We find supportive empirical evidence for the hypothesis that higher personal income tax progressivity leads to lower output volatility. All other factors constant, countries with more progressive personal income tax systems seem to benefit from stronger automatic stabilisers.

What explains the surge in euro area sovereign spreads during the financial crisis of 2007-09?

This paper uses a dynamic panel approach to explain the determinants of widening sovereign bond yield spreads vis-à-vis Germany in selected euro area countries during the period end-July 2007 to end-March 2009, when the financial turmoil developed into a full-blown financial and economic crisis. Emphasis is given to the role of fiscal fundamentals and government announcements of substantial bank rescue packages. The paper finds that higher expected budget deficits and/or higher government debt ratios relative to Germany contributed to higher government bond yield spreads in the euro area during the analysed period. More importantly, the announcements of bank rescue packages have led to a re-assessment, from the part of investors, of sovereign credit risk, first and foremost through a transfer of risk from the private financial sector to the government.

Revisiting the bi-directional causality between debt and growth:Evidence from linear and nonlinear tests

We revisit the bi-directional causality between public debt and the rate of GDP growth for 10 EMU countries alongside the US, UK and Japan, over sample periods spanning from 1970 up to 2014 whilst accounting for the nonlinear properties of both the individual time series, and their relation in both directions. Our results indicate that the causal relation between debt and growth, in either direction, is weak at best. For most of the countries in our sample, we find no robust evidence of a long-run causal effect using bi-variate Granger causality tests. Bi-directional causality is detected only for Austria, while for France, Luxembourg and Portugal, causality runs solely from debt to growth, but the estimated effects are very small. In Finland, Spain and Italy, Granger causality (from growth to debt in the former two and debt to growth in Italy) appears to be present in the short-run. Our findings cannot be taken as evidence that a high level of public indebtedness is not risky for the economy or as invalidating hypotheses postulating effects in either direction in the relation between debt and growth

Public debt and growth: heterogeneity and non-linearity

We study the long-run relationship between public debt and growth in a large panel of countries. Our analysis builds on theoretical arguments and data considerations in modelling the debt-growth relationship as heterogeneous across countries. We investigate the debt-growth nexus adopting linear and non-linear specifications, employing novel methods and diagnostics from the time-series literature adapted for use in the panel. We find some support for a negative relationship between public debt and long-run growth across countries, but no evidence for a similar, let alone common, debt threshold within countries
