A note on the subprime mortgage crisis: dynamic modelling of bank leverage profit under loan securitization

摘要

In this brief research article, we consider the financial modelling of the process of mortgage loan securitization that has been a root cause of the ongoing Subprime Mortgage Crisis (SMC). In particular, we suggest a Lévy process-driven model of bank leverage profit that arises from the securitization of a pool of subprime mortgage loans. To achieve this, we develop stochastic models for mortgage loans, mortgage loan losses, credit ratings and mortgage loan guarantees in a subprime context. These models incorporate some of the most important issues related to the SMC and its causes. Finally, we provide a brief analysis of the models developed earlier in our contribution and its relationship with the SMC.View full textDownload full textRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/13504850903035907
