This paper argues that the key issue for defining and solving the Eurozone's (EZ) difficulties lies in readjusting the relationship between the centre and the periphery of the EZ. Our argument proceeds in two steps. Firstly, the basic finance problem of a centre-periphery system is captured by a...

We offer a new methodology for the assessment of public debt sustainability in a stochastic economy when sovereign default taken into account. The default threshold differs from the no-Ponzi condition and depends on the post-default debt recovery rule. We distinguish sustainability and...

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 show that, in many countries, tax compliance is volatile and markedly responds to fiscal policy. To explore the consequence of this novel stylized fact, we build a model of sovereign debt with limited commitment and imperfect tax enforcement. Fiscal policy persistently affects the size of the...

The Greek bail-out was highly controversial. An oft-heard assessment is that i) the bail-out was a mistake, ii) the political haggling over it was irrational and iii) the bail-out will create a moral hazard problem. Contrary to this view, our analysis suggests that, given EMU's present...

This paper argues that the Eurozone crisis stems from a risk management failure in the Eurosystem's design, and that applying insurance theory is useful. We model risk neutral agents choosing portfolios of government bonds of n countries in a monetary union and other assets. We firstly analyse a...

Democracies around the world are making promises to the old at the expense of future generations. I interpret this as reflecting low altruism - a discount rate on children's utility greater than the world interest rate - and I examine the implications in a small open economy with overlapping...

This paper analyses the determinants and effects of ECB interventions in times of severe distress. We focus on the Greek government bond market in mid-2010 and use a unique new dataset to show, for the first time, what type of bonds the ECB bought. We then explore the short-term effects of ECB...

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...
