具有两个不确定因素的不可逆投资问题

On an Irreversible Investment Problem with Two-Factor Uncertainty

Felix Dammann, Giorgio Ferrari

摘要:

本文考虑了利润最大化公司的最优不可逆投资问题的实物期权模型。该公司有机会投资到一个能够生产两种产品的生产工厂,其价格遵循两个独立的几何布朗运动。公司在支付固定的沉没投资成本后,将产品在市场上销售,从而获得连续的随机收入流。该投资问题被设定为一个二维的最优停时问题。我们发现最优投资决策是由一条凸曲线触发的,我们将其刻画为一个非线性积分方程的唯一连续解。此外,我们提供了分析和数值比较静态结果的项目的价值和投资决策的依赖关系模型的参数。

英文摘要:

We consider a real options model for the optimal irreversible investment problem of a profit maximizing company. The company has the opportunity to invest into a production plant capable of producing two products, of which the prices follow two independent geometric Brownian motions. After paying a constant sunk investment cost, the company sells the products on the market and thus receives a continuous stochastic revenue-flow. This investment problem is set as a two-dimensional optimal stopping problem. We find that the optimal investment decision is triggered by a convex curve, which we characterize as the unique continuous solution to a nonlinear integral equation. Furthermore, we provide analytical and numerical comparative statics results of the dependency of the project's value and investment decision with respect to the model's parameters.
