摘要: This paper investigates the pricing of American exchange options when price dynamics each underlying risky asset are assumed to follow a Markov-modulated Geometric Brownian motion; that is, appreciation rate and volatility depend on unobservable states economy described by continuous-time hidden Markov process. We show an option can be reduced option. Then, we modify result Zhu Chan (An analytic formula for with regime switching. Submitted publication, 2012), closed-form analytical is given.
