问题如下:
Kreming’s suggested model for Bond IV is a:
选项:
A.structural model.
reduced-form model.
term structure model.
解释:
B is correct. A reduced-form model in credit risk analysis uses historical variables, such as financial ratios and macroeconomic variables, to estimate the default intensity. A structural model for credit risk analysis, in contrast, uses option pricing and relies on a traded market for the issuer’s equity.
Kreming calculates the risk-neutral probabilities, compares them with the actual default probabilities of bonds evaluated over the past 10 years, and observes that the actual and risk-neutral probabilities differ.
是这一段吗?但是里面只说了和历史数据不一致,没有用到其他的经济数据什么呀?我发现原版书课后题我总是找不到题目对应的点,好像实际考试的时候的题目不会这样。。。
然后A和C选项中,是不是没有structure model?只有term structure model?
