This course introduces a mathematical model for a probabilistic analysis of the possibility of a creditor (lender of money) incurring financial damage from a debtor (borrower of money) defaulting (not returning money as promised) on their debt (generally referred to as "credit risk"), as well as methods for applying the analysis to the pricing of financial products called credit derivatives such as CDS and bonds with credit risk, and to risk evaluation of the many loan portfolios of banks, etc.
We will also cover counter party risk which is of growing importance for derivatives trading in recent years, starting at the basics and working up to the latest research.
We will also touch on the appeal of the mathematical part of modeling credit risk, but we also wish to present the practical viewpoint of how best to utilize the models in order to accurately explain phenomena observed in actual financial markets,
