Abstract : This paper investigates risk-neutral price of European option under dividend barrier strategy when cumulative
log-return of the underlying stock in the absence of dividends follows a Brownian motion with drift. Such a dividend barrier
strategy means that in the presence of dividends, there are no dividend payments when cumulative log-return is below a
positive constant barrier b, and dividends in the case of cumulative log-return larger than barrier b are paid to ensure that
cumulative log-return is reflected and bounded by barrier b. Overflow over dividend barrier b can be expressed in terms of
running maximum of a Brownian motion with drift. Under dividend barrier strategy and risk neutral probability measure, we
use joint probability density function of Brownian motion with drift and its running maximum to derive closed-form
European call option pricing formula which will be reduced to classical Black-Scholes-Merton option pricing formula in
some sense as dividend barrier approaches positive infinity.
