A multivariate data set, which exhibit complex patterns of dependence, particularly in the tails, can be modelled using a cascade of lower-dimensional copulae. In this paper, we compare two such models that differ in their representation of the dependency structure, namely the nested Archimedean...

We investigate the pricing of sovereign credit risk over the period 2008-2010 for selected advanced economies by examining two widely-used indicators: sovereign credit default swap (CDS) and relative asset swap (RAS) spreads. Cointegration analysis suggests the existence of an imperfect market...

Large number of facts and data during previous decades are bringing to conclusion that level of financial system development is very important for economic growth of one national economy. Subject of this chapter is development level of financial system of transition countries, as well as its...

This study provides a rigorous empirical comparison of structural and reduced-form credit risk frameworks. The literature differentiates between structural models that are based on modeling of the evolution of the balance sheet of the issuer, and reduced-form models that specify credit risk...

In its complexity and its vulnerability to market volatility, the constant proportion debt obligation (CPDO) might be viewed as the poster child for the excesses of financial engineering in the credit market. This paper examines the CPDO as a case study in model risk in the rating of complex...

This paper introduces a strong and controversial point of view, which we believe may help foster debate about a number of fundamental high-level issues currently affecting the financial industry. <p> The Capco Institute is open to controversial ideas. The Journal of Financial Transformation will...</p>

The article presents an empirical analysis of the interaction between market power of Russian banks and their resistance to credit risk during 2004Q1–2011Q2. We employ individual concentration index of banks in different asset markets (structural measure) and the Lerner index (unstructured...

This paper contributes to the literature on default in general equilibrium. Borrowing and lending takes place via a clearing house (bank) that monitors agents and enforces contracts. Our model develops a concept of bankruptcy equilibrium that is a direct generalization of the standard general...

We characterize diversification in corporate credit using a new class of dynamic copula models which can capture dynamic dependence and asymmetry in large samples of firms. We also document important differences between credit spread and equity return dependence dynamics. Modeling a decade of...

This paper extends Merton's structural credit risk model to account for the fact that the firm's asset volatility follows a stochastic process. With the presence of stochastic volatility, the transformed-data maximum likelihood estimation (MLE) method of Duan (1994, 2000) can no longer be...
