CIRJE-F-335. Takahashi, Akihiko and Nakahiro Yoshida, "Monte Carlo Simulation with Asymptotic Method", April 2005.

We shall propose a new computational scheme with the asymptotic method to achieve variance reduction of Monte Carlo simulation for numerical analysis especially in finance. We not only provide general scheme of our method, but also show its effectiveness through numerical examples such as computing optimal portfolio and pricing an average option. Finally, we show mathematical validity of our method.
