Path-dependent currency options with mean reversion

This paper develops a path-dependent currency option pricing framework in which the exchange rate follows a mean-reverting lognormal process. Analytical solutions are derived for barrier options with a constant barrier, lookback options, and turbo warrants. As the analytical solutions are obtained using a Laplace transform, this study numerically shows that the solution implemented with a numerical Laplace inversion is efficient and accurate. The pricing behavior of path-dependent options with mean reversion is contrasted with the Black-Scholes model. (C) 2008 Wiley Periodicals, Inc.
