Optimal funding and hiring/firing policies with mean reverting demand

•This paper analyzes the firm's investment and hiring/firing optimal policies.•It provides a general result when the market demand is mean reverting.•This allows the extension of Tserlukevich (2008) and Letifi and Prigent (2014).•We analyze the impact of the mean-reverting parameters on both the growth and decay options.

We analyze the firm's investment and hiring/firing optimal strategies when the market demand is mean reverting and with potential decision reversibility. In this framework, we determine the values of both investment and hiring/firing growth and shutdown options. This allows the extension of Tserlukevich (2008) and Letifi and Prigent (2014) when taking account of a mean reverting demand. We analyze the quasi-explicit solutions for the optimal firm's value, especially the influence of mean-reverting parameters on both the growth and decay options.
