Defaultable Game Options in a Hazard Process Model
by Tomasz R. Bielecki of the Illinois Institute of Technology,
Abstract: The valuation and hedging of defaultable game options is studied in a hazard process model of credit risk. A convenient pricing formula with respect to a reference filteration is derived. A connection of arbitrage prices with a suitable notion of hedging is obtained. The main result shows that the arbitrage prices are the minimal superhedging prices with sigma martingale cost under a risk neutral measure.
