摘要: We develop a class of discrete, path-independent models to compute prices American options within the Black-Scholes (1973) framework, including in which state variables have time-varying volatility functions and with multiple variables. Time-varying are illustrated applications term structure developed by Vasicek (1977) Heath, Jarrow, Morton (1988), (1990). Distinct from previous work literature, multivariate suggested this paper consistent arbitrarily large, though constant, covariance functions. Finally, we compare contrast numerical accuracy large number simulation results.
