We shall only present classical numerical methods and the basics results that we need for option pricing. Simulation and algorithms for financial models.

Chapter 4, Section 4. To model this kind of phenomena, we have to introduce discontinuous stochastic processes.

Bielecki and Marek Rutkowski. For more details, the diligent reader can refer to Dudley A conse- quence of this proposition and Proposition 1. A very similar idea can be used for pricing basket or index options.

The number fi is supposed to be an approximation of f xi. He sells the option at a price V0 at time 0 and then follows an admissible strategy between times 0 and T.

We then have to make sure that this model is compatible with hypothesis H. For example, a European call on the dollar, with maturity T and strike price Kis the right to buy, at time Tone dollar for K euros. Prove that S is FS -measurable. These models are rather less optimistic than the Black-Scholes model and seem to be closer to reality.


The second chapter deals with American options. That is the case of the so-called Asian options, 2 Or, more generally, a contingent claim. Note that the compo- nents of too vector can be assumed to be standard normal variables, since the copula is invariant under increasing transformations of the coordinates. Relate this method to the call-put arbitrage relation.

That completes the proof of 3. Controlled Markov processes and vis- cosity solutions, volume 25 of Stochastic Modelling and Applied Probability. Show, using equation 1. We want to price and hedge European options with maturity T in this model.

Conclude that the market is arbitrage-free and complete. This is obviously more complex and more time consuming. The above method is the so-called Cox-Ross-Rubinstein method and it is presented in detail funance Cox and Rubinstein In practice, parameters must be estimated and a value for r must be chosen.

Sometimes we need to know how to simulate the whole path of a process for example, when we are studying the dynamics through time of the value of a portfolio of options; see Exercise On the theory of option pricing. Vetterling, and Brian P. Martingales and stochastic integrals in the theory of continuous trading.


The vector x0 is nothing but the projection of the origin on the closed convex set C. Nevertheless, it leads to a heuristic approach: We have, using Proposition 6.

BouleauChapter VI, Section 7. Compare the precision of this method with the previous one using various values for K and S0.

Thus, the ,amberton expectation of X given B appears as the least-square best B -measurable predictor of X. On the pricing of corporate debt: If the option is exercised, the writer must be able to deliver a stock at price K.
