Credit risk


This course deals with credit risk modeling, as well as the valuation methods of credit derivatives and financial products exposed to this risk. It will first focus on an empirical analysis of default probabilities, recovery rates and rating transitions. Then, the main credit derivatives will be described: financial characteristics, risk factors and market conditions. We will then study their valuation models. The objective is to enable students to have a global vision of credit risk and the different models used for the valuation of products exposed to this risk.
