Abstract:
In this paper, we derive expressions for conditional expectations in terms of regular expectations without conditioning but involving some weights. For this purpose we apply two approaches: the conditional density method and the Malliavin method. We use these expressions for the numerical estimation of the price of American options and their deltas in a Lévy and jump-diffusion setting. Several examples of applications to financial and energy markets are given including numerical examples.
