Abstract We give a unified mathematical framework for reduced-form models for portfolio credit risk and identify properties which lead to positive dependence of default times. Dependence in the default hazard rates is modeled by common macroeconomic factors as well as by inter-obligor links. It...

A new model of credit risk is proposed in which the intensity of default is described by an additional stochastic differential equation coupled with the process of the obligor’s asset value. Such an approach allows us to incorporate structural information as well as to capture the effect of...

This note provides a simple proof of the necessity of the transversality condition for the differentiable reduced-form model. The proof uses only an elementary perturbation argument without relying on dynamic programming. The proof makes it clear that, contrary to common belief, the necessity of...

A closed-form formula for the analysis of defaultable bonds is essential for market practitioners and financial researchers. In order to make the model more reasonable without loss of generality, it is necessary to specify the stochastic processes of the default-free short interest rate, the...

Premiums collected when warrants are issued become part of a firm's capital and are taken into account in the valuation of a company. In this paper formulae are developed to fairly value warrants in the case where multiple warrant issues are outstanding, including consideration of issue premiums...

he role of selling (or marketing) period uncertainty in understanding risk associated with property investment is examined in this paper. Using an approach developed by Lin (2004), and Lin and Vandell (2001, 2005), combined with a statistical model of UK commercial property transactions, we show...

South Africa will be implementing Basel II on 1 January 2008. Basel II provides regulatory capital requirements for credit risk, market risk and operational risk. The purpose of capital requirements is to level the playing field for all internationally active banks and to protect consumers...

Subprime residential mortgage loan securitization and its associated risks have been a major topic of discussion since the onset of the subprime mortgage crisis (SMC) in 2007. In this regard, the thesis addresses the issues of subprime residential mortgage loan (RML) securitization in discrete-,...
