MATHEMATICS COLLOQUIUM
Speaker: Xin Guo Abstract. The credit risk crisis of 2007 and the resultant financial institution failures, including the collapse of Lehman Brothers in September of 2008, highlights the importance of an accurate assessment of the risks of the institution's investments. Crucial to the calculation of the risk of the institution's investments is the correct measurement of the timing of default. In this talk, we will briefly review the traditional models for default and introduce and build a model for a new notion of default: economic default. This new notion and model framework will then be compared with the old ones and will be related to the classical Arcsine Law distribution. This is based on joint works with R. A. Jarrow (Cornell U.), A. de Larrard (Paris 6), and H. Lin (Credit Swiss First Boston) |
