Ramsey Waits: A Theory of Non-Exclusive Real Options with First-Mover Advantages

This paper analyses the exercise decision of non-exclusive real options in a two-player setting. A general model of non-exclusive real options, allowing the underlying asset to follow any strong Markov process is developed, thus extending the existing literature, which is mainly based on one-dimensional geometric Brownian motion. For games with a first-mover advantage it is proved that an equilibrium with the rent-equalisation property exists. As an example, a duopoly where two firms can adopt a new technology, whose profitability follows a two-dimensional, correlated geometric Brownian motion is studied.
