This paper examines a declining duopoly, where the firms must choose when to exit from the market. The uncertainty is modeled by letting the revenue stream follow a geometric Brownian motion. We consider the Markovperfect equilibrium in firms’ exit strategies. With a low degree of uncertainty there is a unique equilibrium, where one of the firms always exits before the other.
