Le Gall and D. Consider a put and a call with the same maturity T and exercise price Kon the same underlying asset which is worth St at time t.

Write a recursive algorithm to compute u 0, x, 0. Exercise 30 The reader may use the results of Exercise 21 of Chapter 3. Let Pe be the function pricing stocjastic European put with maturity T and strike price K: Indeed, according to Theorem 3. Let St be the price of the dollar at time t, i.

To do that, we shall use the integration by parts formula. The last section is devoted to the concept of cop- ula, which is very useful in models involving several default times. To do so, we use the same method as in the Black-Scholes model.

II We would like to price and caalculus a European call on one dollar, with maturity T and strike price Kusing a Black-Scholes-type method. Journal of Financial and Quantitative Analysis Z Kemna and A. Study the functions Fc t. Suppose that we want to evaluate E X.

In fact, some of the problems in Chapter 4 can be addressed in this way especially, the problem stochastc the Garman-Kohlagen model and the one on Asian options: He sells the option at a price V0 at time 0 and then follows an admissible strategy between times 0 and T. These questions are addressed in Chapter 5. We now extend these techniques to the case of path-dependent options.

John Wiley and Sons, New York, Processus Stochastiques et Applications. According to Girsanov theorem see Theorem funance. We also assume joint continuity with respect to t, T. Then we operate as follows: A proof is sketched in Exercise 1 below, based on Rogers Chapter 3, Sec- tion 3.

For a full proof, the reader ought to refer to Friedman The main addition concern: Stochasttic particular, the following theorem is useful when we do computations involving interest rate models. Bielecki and Marek Rutkowski. Use the same hedging strategies for a combination of put and call op- tions.

In practice, parameters must be estimated and a value for r must be chosen. Chapter 3, Exercise
