This paper presents three factor "Extended Gaussian" term struc- ture models (EGM) to price default-free and defaultable bonds. To price default-free bonds EGM assume that the instantaneous interest rate is a possibly non-linear but monotonic function of three latent factors that follow...

This paper presents a tractable structural model whereby controlling equity holders are also among the creditors of the firm. As the firm approaches distress, equity holders can depauperate the firm and expropriate other creditors by repaying their credit before bankruptcy. The bankruptcy...

This paper extends the results on quadratic term structure models in continuos time to the discrete time setting. The continuos time setting can be seen as a special case of the discrete time one. Recursive closed form solutions for zero coupon bonds are provided even in the presence of multiple...

This paper presents a tractable bond valuation model, which further develops the approach proposed by Piazzesi (2005). The short term inter-bank interest rate is equal to the target rate set by the central bank plus a spread. Bond yields are driven by the intensities that determine the...

This paper presents an equity valuation model that employs risk-neutral valuation under stochastic interest rates along the lines of Ohlson and Feltham (1999). Closed form valuation formulae for equities are presented in a discrete time setting whereby the short term interest rate is modelled by...

This paper presents three variants of a tractable structural model in which default may take place both expectedly and unexpectedly. The model has the merit of predicting realistically high short term credit spreads. Closed form solutions are provided for corporate bonds (and default swaps) when...

Both borrowers and creditors often have an implicit option to extend debt maturity as the debtor approaches financial distress. This implicit "extension option" is associated with the possibility for debtors and creditors to renegotiate the debt contract in the hope that extending debt maturity...

This paper presents an extended structural credit risk model that pro- vides closed form solutions for fixed and floating coupon bonds and credit default swaps. This structural model is an "extended" one in the following sense. It allows for the default free term structure to be driven by the a...

This paper presents, estimates and tests a reduced form sovereign credit default swap (CDS) pricing model where the default intensity is driven by two latent Black-Karasinski-type processes. CDS pricing re- quires finite difference numerical solutions, but parameter estimation is still feasible....

This paper provides a structural valuation model for exchangeable convertible bonds, since such bonds are widespread by now. The model is solved through the Hopscotch finite difference method. As the issuer owns the underlying shares, exchangeable convertibles may be called and the exchange...
