摘要: 本文利用我国住房抵押贷款持续期数据,对贷款终止的提前还款和违约这两种情形展开研究,估计了竞争风险下Cox比例危险模型,刻画我国住房抵押贷款的两类风险概率随协变量变化的时间效应。对竞争风险下的Cox比例危险模型,本文计算了相应的Cox-Snell残差和Deviance残差用于模型的拟合检验,检验表明本文估计的竞争风险模型用于抵押贷款持续期数据的分析是合适的。本文进一步讨论了基于持续期的贷款终止风险研究在银行抵押贷款证券化和信贷风险管理中的意义。

Abstract: In this paper, the prepay and default risk of house mortgage loan are studied by duration data analysis. We estimated Cox proportional hazard model under competing risks, and calculated the Cox-Snell residual and Deviance residual used for the test of model fit, which indicate that the competing risk frailty models fit well for the empirical data. This empirical study can describe the inherent time effect of the duration of mortgage loan risk. Furthermore, the application of this empirical study in the mortgage-backed securities and credit risk management is discussed in this paper.
