摘要
讨论发行债券公司持有另一公司的股票时,公司所持股票公司的破产概率对公司本身的破产概率和债券定价的影响.对公司的破产采用约化方法和市价回收,在利率是随机假定下分别给出了债券定价和违约概率的显式表达式,并讨论了其金融意义.
A study is made of the influence of the default of one company on another company and the bond pricing of the latter when the latter holds a part of the former company' s share. Based on the reduced form approach and market value recovery, under the assumption of stochastic interest rate, the close form formula for both the pricing of the bond and default probability are obtained. Finally, this paper presents a disussion on the financial meaning of the default contagion.
