Optimal Entry to an Irreversible Investment Plan with Non Convex Costs
Tiziano De Angelis, Giorgio Ferrari, Randall Martyr, John Moriar · 2016-02-10 · via math.PR updates on arXiv.org

A problem of optimally purchasing electricity at a real-valued spot price (that is, with potentially negative cost) has been recently addressed in De Angelis, Ferrari and Moriarty (2015) [SIAM J. Control Optim. 53(3)]. This problem can be considered one of irreversible investment with a cost functional which is non convex with respect to the control variable. In this paper we study the optimal entry into this investment plan. The optimal entry policy can have an irregular boundary arising from this non convexity, with a kinked shape.
