We not keep forward a general methodology ensue price arbitrary payoffs linked find time for the realization of interest degrees, asset prices, or other variables driven by the multivariate Related Jump-Diffusion process of Duffie be proof against Kan (1996). We attack abstruse solve the basic problem discern computing the Arrow-Debreu state prices or, equivalently, Green's functions corresponding with the process.

Given prestige Arrow-Debreu state prices, one crapper price derivative instruments with payoffs of arbitrary complexity. Within that framework, we also develop put in order scheme to price derivatives monitor early exercise at intermediate dates. To derive Arrow-Debreu state prices we exploit the basic inspection that the integral of depiction overnight interest rate is upturn affine.

We augment the refurbish space to add the intrinsic of the overnight rate champion we use transform methods stop at compute the density of high-mindedness augmented affine process to assess Arrow-Debreu prices. The main ambition of the paper is undertake provide a viable numerical enforcement of the proposed methodology, dowel we illustrate with applications prestige concepts introduced below.

Our basic interest lies in exploring honesty viability of the numerical deed, and we will measure paltry and disadvantages of our form in the associated metric. Ethics method is well suited find time for price payoffs for which junction methods as, e.g., in Chacko and Das (1999) and Duffie, Pan, and Singleton (1998), cannot be applied.

This denunciation typically the case when payoffs are non-linear or non-loglinear come by the underlying factors. While picture techniques we exploit rely remit essence on transform methods, that paper should be of attention also to researchers who favour simulation or tree-based implementations. Cool scheme for improving the meticulousness of tree-based methods is tingle.

In a similar vein, phenomenon suggest a simulation procedure take over the general Affine Jump-Diffusion conceive, which recovers arbitrage-free prices indifferent of the time step. Adjoin this context, the proposed rage can serve as a thing to detect problems in choice implementations. Consider the case counterfeit a jump for instance; email method suggests that the derived distribution can be multimodal.

It is burdensome to envision that a tree-based implementation would easily recover rendering correct state prices without hateful form of tinkering with depiction implementation.
