....non smooth. A Greek is therefore a measure of the sensibility of this price with respect to its parameters. In particular, it could serve to prevent future dangers in the position of a company holding these options. The problem of computing Greeks in Finance has been studied by various authors: [4 8], among others. Let us take a closer look at the problem. If the Leibnitz rule of interchange between expectation and di#erentiation were true then we would have #P(#) #E[#(X(#) #) # # (X(#) #) #X(#) ##(X(#) #) 7) When the above expression does not have a close formula then one ....

....AND KENNETH H. KARLSEN Abstract. In this paper we consider the evaluation of sensitivities of options on spots and forward contracts in commodity and energy markets. We derive di erent expressions for these sensitivities, based on techniques from the recently introduced Malliavin approach [8, 9]. The Malliavin approach provides representations of the sensitivities in terms of expectations of the payo and a random variable only depending on the underlying dynamics. We apply Monte Carlo methods to evaluate such expectations, and to compare with numerical di erentiation. We propose to ....
....estimations of the expectation, while the alternative approaches mainly rewrite of the expression for the price, and thus require only one estimation of an expectation. To derive alternatives to numerical di erentiation, we shall use the recently introduced Malliavin approach (see Fourni e et al. [8, 9]) which in our setting is a generalization of the density approach. The density approach moves the di erentiation of the price to a di erentiation of the (known) probability density of the underlying, thus avoiding taking the derivative of the payo function. The Malliavin approach generalizes ....

The proof of Theorem 4.2 uses the reference probability approach, and follows the same lines as the proof of Proposition 3. 1 in Fourni e et al.
