Wealth transfer effects between stockholders and bondholders on the announcement date of changes in a firm's credit rating have primarily been examined a) for one type of security; b) on US capital markets; and c) by applying standard event study methods. In contrast to these investigations, we...

This research aims to model the relationship between the credit risk signals in the credit default swap (CDS) market and agency credit ratings, and determines the factors that help explain the variation in such signals. A comprehensive analysis of the differences in the relative credit risk...

This article compares the linkages between credit fundamentals, ratings and value-at-risk measures for CDO tranches with those for corporate bond exposures. A sensitivity analysis incorporating market information and rating migrations data reveals that the behaviour of CDO tranche ratings can...

We investigate the relationship between credit rating events and credit default swap spreads for EU countries around the Subprime and European Debt Crises. Using event studies and OLS regressions we analyse the behavior of CDS spreads before, around and after credit rating events. Our results...

Market-implied ratings gained importance as efficient early warnings of official credit rating migrations. We build a two-dimensional implied rating system that gathers information from both the bond and the CDS markets. The system is able to outdo each of the corresponding one-dimensional...

We empirically investigated the impact of regulatory risk retention methods on credit ratings and pricing at issuance using a sample of European securitization tranches issued in the period 2011-2021. European regulation is based on the assumption that all risk retention methods homogenously...

This thesis focuses on the mechanics of microfinance collateralized debt obligations (MiCDOs) and outlines crucial risk factors for international investors and microfinance institutions (MFIs), in contrast to already established collateralized debt obligations (CDO) and their rating systems. Due...

This paper provides the first empirical investigation of the influence of credit default swaps (CDS) on the surge in subprime mortgage defaults, which is widely believed to be a driving force in the 2008/2009 financial crisis. In the years just before the 2008/2009 financial crisis, private...

We offer the first empirical evidence on the adverse effect of credit default swap (CDS) coverage on subprime mortgage defaults. Using a large database of privately securitized mortgages, we find that higher defaults concentrate in mortgage pools with concurrent CDS coverage and within these...

Interconnectedness between economic institution and sectors, already recognised as a trigger of the great financial crisis in 2008-2009, is assuming growing importance in financial systems. In this paper we study contagion effects between corporate sectors using financial network models, in...
