They considered equity and interest rate risk using the Cox-Ross-Rubinstein (CRR) equity tree and Ho-Lee interest rate tree, and also modeled default risk in the manner of Jarrow and Turnbull (1995). They finally combined the equity tree and interest tree tree by taking their correlation into account and therefore constructed a two-factor multinomial tree model. We extend their model to account for the empirical relationship between equity price and default intensity. The intensity function introduced by Takahashi, Kobayashi, and Nakagawa (2001) is applied in our framework to match this fact. We further provide sensitivity analyses on how the assumed parameters affect the valuation of convertible bonds. At last, we use the model to price the convertible bonds issued in Taiwan market in 2006. Comparing the results with Lee (2006), we moderately reduced the relative error from 0.2115 to 0.1779.目錄要 IIIBSTRACT IV一章 緒論 1一節 研究動機 1二節 研究架構與流程 3二章 文獻回顧 4三章 研究方法 8一節 股價與利率之二因子樹狀模型 8二節 考慮信用風險之二因子樹狀模型 10三節 計算可轉換公司債價值 15四章 實證結果與分析 21一節 模型比較 21二節 敏感度分析 30三節 國內可轉換公司債價值實證 35五章 研究結論與建議 38一節 研究結論 38二節 後續建議 39錄一 國內可轉換公司債實證結果 40考文獻 43application/pdf1228688 bytesapplication/pdfen-US可轉換公司債信用風險convertible bondscredit risk考慮信用風險之可轉換公司債二因子樹狀評價模型Two-Factor Tree Model for Pricing Convertible Bonds with Default Riskthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/182600/1/ntu-97-R95723059-1.pdf
