Abstract

Recently, Cai, Song, and Kou (2015) proposed closed-form double transform approximation formulas for prices of both discretely and continuously monitored Asian options under the setting of a general continuous-time Markov chain. In this note, we analytically invert the Z-transform and the Laplace transform involved in their final results, respectively, for the discretely and the continuously monitored cases, and we obtain explicit single Laplace transforms of option prices. This reduction in the dimension of numerical integral has meaningful consequences both in computational efficiency and in practical implementation of the formulas. Extensive numerical experiments illustrate the improved performance of our results.
