We solve the problem of mean-variance hedging for general semimartingale modelsvia stochastic control methods. After proving that the value process of theassociated stochastic control problem has a quadratic structure, we characteriseits three coefficient processes as solutions of semimartingale...

In this note the pricing of options on credit default swaps using the survival-measure -pricing technique is discussed. In particular, we derive amodification of the famous Black (1976) futures pricing formula which appliesto options on CDS, and show how other pricing formulae can be easily...

We study the exponential utility indifference valuation of a contingentclaim H when asset prices are given by a general semimartingale S. Under mildassumptions on H and S, we prove that a no-arbitrage type condition is fulfilled ifand only if H has a certain representation. In this case, the...
