In this paper we propose to use beta-component mixtures to model the market-implied severity. In our analysis we extract and identify recovery rates from credit default swaps instead of using defaulted bonds. The main advantage of extracting implied, endogenous and dynamic functions of recovery rates from credit default swaps versus using defaulted bonds is that it allows to identify recovery rates of low probability of default companies. We carry out an empirical analysis and our results show that a single beta distribution is rejected as a correct specification for implied recovery rates while a beta-component mixture is accepted. Futhermore, we highlight the importance of this modeling approach by focusing on its role for credit VaR.
