本研究以Amraoui & Hitier (2008)隨機回復率模型(BNP model)以及Andersen and Sidenius(2004)隨機風險因子承載係數模型(RFL model)為基礎,進行對分劵信用價差、債劵群組累積損失機率分配,以及對基準違約相關係數的影響等分析。我們發現當回復率改成動態後可以反映更多系統風險,權益分劵信用價差絕大多數都會下降。在累積損失機率分配方面加入BNP後變為較平滑;改用RFL則會使機率分配在小額損失處又產生一次起伏;同時考量BNP與RFL會使小額損失發生機率減少、極端損失機率增加。實作三組市場資料時,發現不管市場違約機率高或低,共同考慮BNP與RFL的模型在四個模型中是最適合擬和市價的,顯示在市價的校準上有更多彈性,特別是在承擔名目本金60~100%先償分劵的校準上只有共同考慮BNP與RFL的模型能發揮功效。
