For American-style Asian options, i.e. options with the early exercise feature, Večeřs approach does not work.[7], [8] Thus, to price American-style fixed-strike Asian options one has to solve the two-dimensional PDE, and for American-style floating-strike Asian options one can solve the reduced PDE.

WebbBased on the quadratic approximation of MacMillan (1986) and Barone-Adesi & Whaley (1987), Ju & Zhong (1999) looks to improve on the quadratic approximation - particularly for very short or very long dated option maturities. The value of an American option under this model is given as: Where if equal to 1 for a call option and -1 for a put option, WebbWe present a simple numerical method to find the optimal exercise boundary in an American put option. We formulate an intermediate function with the fixed free boundary that has Lipschitz character near optimal exercise boundary. Employing it, we can easily determine the optimal exercise boundary by solving a quadratic equation in time …
