Abstract

We study dynamic decision-making scenarios where the decision maker has several consultants at her disposal, and at every period, chooses between taking an action or getting information on the underlying state through one of the consultants. We explore the optimal strategy, and find that if one of the consultants discloses the state with a positive probability, this consultant will be used in all optimal strategies, provided the consultation cost is sufficiently small.

在动态投资问题中选择顾问

我们研究动态决策场景，其中决策者有几个顾问可供她使用，并且在每个时期，选择采取行动还是通过其中一个顾问获取有关潜在状态的信息。我们探索了最优策略，发现当其中一个顾问以正概率披露状态时，在咨询成本足够小的情况下，该顾问将被用于所有最优策略。

期刊介绍： Operations Research Letters is committed to the rapid review and fast publication of short articles on all aspects of operations research and analytics. Apart from a limitation to eight journal pages, quality, originality, relevance and clarity are the only criteria for selecting the papers to be published. ORL covers the broad field of optimization, stochastic models and game theory. Specific areas of interest include networks, routing, location, queueing, scheduling, inventory, reliability, and financial engineering. We wish to explore interfaces with other fields such as life sciences and health care, artificial intelligence and machine learning, energy distribution, and computational social sciences and humanities. Our traditional strength is in methodology, including theory, modelling, algorithms and computational studies. We also welcome novel applications and concise literature reviews.
