TY - JOUR T1 - A Loss Severity Model for Residential Mortgages JF - The Journal of Fixed Income SP - 5 LP - 31 DO - 10.3905/jfi.2008.712347 VL - 18 IS - 2 AU - Lakhbir S. Hayre AU - Manish Saraf Y1 - 2008/09/30 UR - https://pm-research.com/content/18/2/5.abstract N2 - The loss severity model, combined with prepayment and default models, can be used to project loss-adjusted cash flows for mortgage pools and deals. In addition, the loss model can be used for identifying potentially risky loans in a portfolio of subprime loans. In this article we analyze loss severities on mortgage loans with varying borrower and loan characteristics, and we develop a predictive model for projecting losses. We also show that simplistic models that rely heavily on loan-to-value ratio produce unreliable loss severity projections and that a more comprehensive approach, such as the one described in this article, is required for accurately estimating credit risk.TOPICS: MBS and residential mortgage loans, big data/machine learning, legal and regulatory issues for structured finance ER -
