电力公司最优投资与消费的机会过程

The Opportunity Process for Optimal Consumption and Investment with Power Utility

Marcel Nutz

摘要:

研究了半鞅金融市场中幂效用随机场的效用最大化问题,考虑了有无中间消费。引入机会过程的概念作为所得到的随机控制问题的价值过程的简化形式。我们展示了机会过程如何描述关键对象:最优策略,价值函数和对偶问题。应用所得结果得到了最优消费的单调性。

英文摘要:

We study the utility maximization problem for power utility random fields in a semimartingale financial market, with and without intermediate consumption. The notion of an opportunity process is introduced as a reduced form of the value process of the resulting stochastic control problem. We show how the opportunity process describes the key objects: optimal strategy, value function, and dual problem. The results are applied to obtain monotonicity properties of the optimal consumption.
