We examine crossborder contagion from a number of financial systems to the German financial system using the information content of CDS prices in a GARCH model. After controlling for common factors which may cause comovement in security prices, we find evidence for contagion from the US and...

We introduce a new measure of systemic risk, the change in the conditional joint probability of default, which assesses the effects of the interdependence in the financial system on the general default risk of sovereign debtors. We apply our measure to examine the fragility of the European...

This paper presents a methodology to examine the multivariate tail dependence of the implied volatility of equity options as an early warning indicator of systemic risk within the financial sector. Using non-parametric methods of estimating changes in the dependence structure in response to...

This research examines the effects of securitization on the bank's risk exposure both in terms of individual expected shortfall and marginal expected shortfall as a measure of systemic risk. The relationship between securitization activity and tail risks is especially relevant in light of the...

Extensive regulatory changes and technological advances have transformed banking systems to a great extent. Banks have reacted to the challenges posed by the new operating environment by creating new products and expanding their activities to some uncharted business areas. In this paper, we...

In this paper, we examine the systemic risk implications of banking institutions that are considered ‘Too-systemically-important-to-fail’ (TSITF). We exploit a sample of bank mergers and acquisitions (M&As) in nine EU economies between 1997 and 2007 to capture safety net subsidy effects and...

Deposit insurance is widely offered in a number of countries as part of a financial system safety net to promote stability. An unintended consequence of deposit insurance is the reduction in the incentive of depositors to monitor banks which lead to excessive risk-taking. We examine the relation...

The turmoil in the sovereign debt markets in Europe has raised concerns on the usefulness of sovereign credit default swaps and government bond yields in periods of distress. In addressing this issue, we introduce a novel nonlinear approach for the analysis of non-stationary multivariate data...

The aim of our paper is to price credit derivatives written on a single name when this name is a bank. Indeed, due to the special structure of the balance sheet of a bank and to the interconnections with other institutions of the financial system, the standard pricing formulas do not apply and...

This thesis contributes to the analysis and measure of systemic risk through four chapters. In the first chapter, we discuss the notion of systemic risk and detail the methodological issues of modeling. The second chapter proposes a structural model of solvency contagion. Within an equilibrium...
