We consider an optimal investment problem when a firm such as an electric power company has the operational flexibility to expand and contract capacity with fixed cost. This problem is formulated as an impulse control problem combined with optimal stopping. Consequently, we obtain optimal...

In this article, we study a firm's merger strategy. When two firms merge, there are two types of transaction costs: fixed and proportional. To study the firm's merger strategy, we formulate the problem faced by the newly merged firm's management as an optimal stopping problem. Then, we derive...

This paper investigates an environmental policy designed to reduce the emission of pollutants under uncertainty, where the agents' problem is formulated as an optimal stopping problem. We first analyze the single-agent's case according to Pindyck [Pindyck, R.S., 2002. Optimal timing problems in...
