This paper analyzes the independence of boards of directors as an optimally chosen, non-contractible behavior. A board behaves loyally to a CEO when it agrees to a negative NPV-pro ject, giving the CEO private benefits. While the CEO benefitsfrom competent directors because they help him make...

An agent shows loyalty to his manager by bearing personal costs to the superiors benefit. In return, the manager may offer various forms of rewards. If this exchange is not contractible, typically repeated interaction will be required to sustain it. Beyond loyalty, the manager is interested in...

Recent organizational theories suggest that there is a tradeoff between loyalty and competence. This paper tests several such theories in the context of public agencies. Prime ministers, chancellors, and kings alike need to secure the (efficient or inefficient) loyalty of their agencies, such as...

In recent years, tradeable permits (TP) have become widespread in use. One noteworthy point is that the international experience is rather small. Europe has only relatively recently begun to develop such programs. There is a wealth of resources available that comment on the rise of these...

Due to their underlying assumptions, the standard concepts of risk aversion and preference for the present are generally defined separately and represented by scalar measures, and this implies many shortcomings. More specifically, if measured by a scalar, the risk aversion remains unchanged,...

In this paper, we consider an incomplete market framework and explain how to use jointly observed prices of the underlying asset and of some derivatives written on this assetfor an efficient pricing of other derivatives. This question involves two types of moment restrictions, which can be...

The aim of this paper is to explain why cross-sectional estimated migration correlations displayed in the academic and professional literature can be either not consistent, or inefficient, and to discuss alternative approaches. The analysis relies on a model with stochastic migration in which...

In this paper we explain how to use rating histories provided by the internal scoring systems of banks and by rating agencies in order to predict the future risk of a set of borrowers. The method is developed following the steps suggested by the Basle Committee. To introduce both migration...

In this paper we provide a convenient econometric framework for the analy-sis of nonlinear dependence in financial applications. We introduce models withconstrained nonparametric dependence, which specify the conditional distrib-ution or the copula in terms of a one-dimensional functional...

The aim of this paper is to extend the results of Jarrow, Yu (2001) onthe spread term structures of corporate bonds. We first consider differentcharacterisations of these term structures, when the available informationcorresponds to the default histories of the firms. The approach is then...
