This paper seeks to identify computationally efficient importance sampling (IS) algorithms for estimating large deviation probabilities for the loss on a portfolio of loans. Related literature typically assumes that realised losses on defaulted loans can be predicted with certainty, i.e., that...

Zero-coupon interest rates are the fundamental building block of fixed-income mathematics, and as such have an extensive number of applications in both finance and economics. The risk-free government zero-coupon term structure is, however, not directly observable and needs to be generated from...

This paper develops and calibrates a structural model of contingent capital. The model can be calibrated to specific institutions and used to provide quantitative guidance on important practical issues. For instance this paper appears to be the first to consider the problem of empirically...

We consider the valuation and analysis of zero-coupon contingent capital bonds (CCBs) in the structural framework. Using Doob's Optional Sampling Theorem (and making virtually no assumptions on asset value dynamics, the terms of conversion or the conversion trigger) we express the value of the...
