On a new corporate bond pricing model with potential credit rating change and stochastic interest rate
Yin, Hong-Ming; Liang, Jin; Wu, Yuan - In: Journal of risk and financial management : JRFM 11 (2018) 4, pp. 1-12
In this paper, we consider a new corporate bond-pricing model with credit-rating migration risks and a stochastic interest rate. In the new model, the criterion for rating change is based on a predetermined ratio of the corporation’s total asset and debt. Moreover, the rating changes are...

Default Risk in Stochastic Volatility Models
Gersbach, Hans - 2010
We consider a stochastic volatility model of the mean-reverting type to describe the evolution of a firm's values instead of the classical approach by Merton with geometric Brownian motions. We develop an analytical expression for the default probability. Our simulation results indicate that the...
