Pricing of Defaultable Securities in a Multi-Factor Quadratic Gaussian Model

Abstract

We present the multi-factor quadratic reduced form model for pricing of credit risky securities. We use quadratic Gaussian processes to model the short term interest rate and the intensity of default showing that we get tractable formulas for the price of credit default swaps and credit default swaptions.
