具有固定调整费用的不可逆投资:一种随机脉冲控制方法

Irreversible investment with fixed adjustment costs: a stochastic impulse control approach

Salvatore Federico, Mauro Rosestolato, Elisa Tacconi

摘要:

本文考虑了一个无限时间范围内的最优随机脉冲控制问题,其动机是一个具有固定调整费用的不可逆投资选择模型。利用黏性解的技巧,并借助非凸性论证,证明了该值函数是相应的拟变分不等式的经典解.这使我们能够表征的结构的延续和行动的地区和建设一个最优控制。最后,我们集中在线性的情况下,讨论,通过数值分析,相对于有关参数的问题的解决方案的灵敏度。

英文摘要:

We consider an optimal stochastic impulse control problem over an infinite time horizon motivated by a model of irreversible investment choices with fixed adjustment costs. By employing techniques of viscosity solutions and relying on semiconvexity arguments, we prove that the value function is a classical solution to the associated quasi-variational inequality. This enables us to characterize the structure of the continuation and action regions and construct an optimal control. Finally, we focus on the linear case, discussing, by a numerical analysis, the sensitivity of the solution with respect to the relevant parameters of the problem.
