This article presents and tests an 'Extended Black' sovereign Credit Default Swap (CDS) pricing model, whereby the default intensity is driven by truncated Gaussian latent factors. CDS pricing requires numerical solutions through finite differences, yet maximum likelihood estimation is still...

This paper examines "Extended Black" term structure models (EBTSM), which are multi-factor extensions of the one-factor Black model (Black, F., 1995. Interest rates as options. Journal of Finance 50, 1371-1376). EBTSM are not affected by the admissibility restrictions that plague canonical...

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 closed form solutions to price secured bank loans and financial leases subject to default risk. Secured debt fair credit spreads always increase in the debtor's default probability, whereas financial leasing fair credit spreads may well decrease in the lessee's default...
