Abstract: The defaultable term structure is modeled using Gaussian random fields. The proposed models are shown to be free of arbitrage under certain drift conditions. We derive explicit pricing formulas for several credit derivatives. This leads to two calibration procedures, where the second one adjusts for scarcity of credit derivatives data. Also, we present a hedging example.
