Show moreThis paper studies (i) the effects of external directors and managerial ownership, and (ii) the effects of shareholder monitoring, on risk-taking at banks. The former is part of the internal control mechanisms, the latter of external control. It also examines the difference between control mechanisms in the UK and in Japan. It shows that shareholder supremacy is likely to weaken corporate governance at banks. In particular, it finds that: (i) the substituted effects between internal and external controls differ between countries, or that the substituted effects of governance mechanisms may not exist; (ii) an internal corporate governance approach to shareholder supremacy increases risk-taking at banks; and (iii) foreign shareholders are likely to increase risk-taking at banks.

Show moreIn this paper we present a model to price and hedge basket credit derivatives and collateralised loan obligation. Based upon the copula-approach by Schönbucher and Schubert (2001) the model allows a specification of the joint dynamics of credit spreads and default intensities, including a speci¯cation of the infection dynamics which cause credit spreads to widen at defaults of other obligors. Because of a high degree of analytical tractability, joint default and survival probabilities and also sensitivities can be given in closed-form which facilitates the development of hedging strategies based upon the model. The model uses a generalisation of the class of Archimedean copula functions which gives rise to more realistic credit spread dynamics than the Gaussian copula or the Student-t-copula which are usually chosen in practice. An example speci¯cation using Gamma-distributed factors is provided. Show less
