Asian options (or average options) are among the most popular exotic options traded actively in the financial markets and have a wide application in equity, currency, commodity, etc. In this paper we obtain a closed-form solution for the double-Laplace transform of the Asian option price under the hyper-exponential jump diffusion model (HEM). Similar results are available in the literature only in the special case of the Black-Scholes model (BSM). Even in the case of the BSM, our approach is simpler as we essentially use only the Ito`s formula and do not need more advanced techniques such as Bessel processes and Lamperti`s representation. Furthermore, our approach is more general as it applies to the HEM. As a by-product we also show that a well-known recursion relating to Asian options has a unique solution in a probabilistic sense. The double-Laplace transforms can be inverted numerically via a two-sided Euler inversion algorithm. Numerical results indicate that our pricing method is fast, stable, and accurate.
This is joint work with Steven Kou from Columbia University.
