We address the problem how to estimate default probabilities for sovereign countries based on market data of traded debt. A structural Merton-type model is applied to a sample of emerging market and transition countries. In this context, only few and heterogeneous default probabilities are...

We propose a hierarchical Marshall–Olkin model of countrywide systemic risk. At the lower level, we model the systemic risk of a crisis within the banking system (that we call “within” systemic risk) and at the higher level we model the probability of a joint default of the banking system...

This paper applies stochastic simulation methods to assess debt sustainability in emerging market economies and provide probability measures for projections of the external and public debt burden over the medium term. The vulnerability of public debt to adverse shocks is determined by a number...

This paper proposes a new framework for the analysis of public sector debt sustainability. The framework uses concepts and methods from modern practice of contingent claims to develop a quantitative risk-based model of sovereign credit risk. The motivation in developing this framework is to...

This paper develops a comprehensive new framework to measure and analyze sovereign risk. Since traditional macroeconomic vulnerability indicators and accounting-based measures do not address risk in a comprehensive and forward-looking way, the contingent claims approach is used to construct a...

Die klassischen, seit Jahrhunderten erprobten Instrumente zur Bewältigung von Staatsbankrotten sind Umschuldung und nachfolgende Abwertung. Charles B. Blankart und Sven Bretschneider, Humboldt-Universität zu Berlin, gehen von einem weiteren Schritt aus: Nach der Umschuldung sei ein Austritt...
