Title: Stock Evolution under Stochastic Volatility: A Discrete Approach
Abstract: This paper examines the pricing of options by approximating extensions
of the Black-Scholes setup in which volatility follows a separate diffusion
process. It gereralizes the well-known binomial model, constructing a
discrete two-dimensional lattice. We discuss convergence issues extensively
and calculate prices and implied volatilities for European- and
American-style put options.
Keywords: binomial model, option valuation, lattice approach, stochastic
volatility
