Greece has reached a point where, under any plausible macroeconomic scenario, public debt will continue growing faster than GDP. Fiscal consolidation alone cannot close the solvency gap. A substantial reduction in the stock of debt is needed. Even post-debt restructuring, there is no guarantee...

This paper puts the Reinhart-Rogoff dataset to a formal econometric testing to see whether public debt has a negative nonlinear effect on growth if public debt exceeds 90% of GDP. Using nonlinear threshold models, we show that the negative nonlinear relationship between debt and growth is very...

We test the hypothesis that the government bond markets in the Eurozone are more fragile and more susceptible to self-fulfilling liquidity crises than in stand-alone countries. We find evidence that a significant part of the surge in the spreads of the PIGS countries in the Eurozone during...

Sovereign defaults are bad news for investors and debtor countries, in particular if a default becomes messy and protracted. Why are some debt crises resolved quickly, in a matter of months, while others take many years to settle? This paper studies the duration of sovereign debt crises based on...

This paper studies the long-run impact of public debt expansion on economic growth and investigates whether the debt-growth relation varies with the level of indebtedness. Our contribution is both theoretical and empirical. On the theoretical side, we develop tests for threshold effects in the...

We study the occurrence of holdout litigation in the context of sovereign defaults. The number of creditor lawsuits against foreign governments has strongly increased over the past decades, but there is a large variation across crisis events. Why are some defaults followed by a “run to the...

We build a new Keynesian DSGE model consisting of two heterogeneous countries participating in a monetary union. We study how public debt consolidation in a country with high debt (like Italy) affects welfare in a country with solid public finances (like Germany). Our results show that debt...

This thesis is a volume comprised of four independent chapters: The overarching topic of the thesis is pensions and fiscal sustainability. An overriding problematic throughout the different chapters is that of demographic ageing. This ageing process, in the form of higher longevity and lower...

We shed light on the function, properties and optimal size of austerity using the standard sovereign debt model augmented to include incomplete information about credit risk. Austerity is defined as the shortfall of consumption from the level desired by a country and supported by its repayment...
