However, the processes modelling stock prices are normally functions of one or several Brownian motions.

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. The events B1.

This is an arbitrage opportunity. Dx marked it as to-read Feb 14, They can be character- ized by the covariance matrix of the Gaussian vector.

Before calculating the price of bonds according to this model, let us give some consequences of equation 6. Using the closed-form formula for ue 0, x see Chapter stocuastic, equation 4. Skip to main content. We consider here the multidimensional Black-Scholes model already intro- duced on page Formally, the method is the same as in the European case: In this case, the Markov property can applieed stated as follows: Firstly, we show that Tn is a stopping time.

How much should the buyer pay for the option?

See Sklar for the general case. We are only going to sketch the proof of this lemma.

The converse property is not true, but we have the following result. Actually, it can be shown cf.

This section suggests some simple tricks to simulate paths of processes. The def- inition of the conditional expectation is based on the following theorem see Jacod and ProtterChapter The following algorithm, known as the Gauss method, solves the system with a number of multiplications proportional to N.

Notations and hypothesis are those of Theorem 4. We shall only state the most important results, but the reader can refer to Glowinsky et al. The horizon N will often correspond to the maturity of the options. We re- fer to Brigo and Mercurio for an exhaustive account of interest rate modelling and a thorough discussion of practical issues. For more information on credit risk models, we refer the reader to the recent second edition of Brigo and Mercurio and, for mathematical developments, to Bielecki and Rutkowski Riding on a smile.

In the case of the call, we have, using the same notations as in Remark 4. In this model, cap prices are easily derived, as sums of caplet prices.
