This thesis presents a new approach to price European-style and American-style Asian basket options. First, we use approximation and moment-matching techniques to find the random variable following the shifted lognormal distribution to approximate the basket value. Second, we use the random variable to build a binomial tree and combine it with the Hull-White methodology for pricing path-dependent options to price Asian basket options. Finally, we compare our numerical results with Monte Carlo simulation for European-style Asian basket options and with the least-squares Monte Carlo for American-style ones. They show that the European-style Asian basket option prices obtained by our approach are accurate and the American-style ones are overpriced by our approach.口試委員會審定書 2 謝辭 3 摘要 4 Abstract 5 Introduction 7 1.
