摘要翻译:
本文研究了一个消费者最初只知道几种产品的搜索问题。在每一个时间点,消费者然后决定是在他已经知道的替代品中寻找,还是发现更多的产品。我证明了这个搜索和发现问题的最优策略是由可处理的保留值充分刻画的。此外,我还证明了一个预先确定的指标完全指定了消费者遵循最优搜索策略的购买决策。最后,比较了经典随机搜索和有向搜索的不同之处。

英文摘要:
This paper studies a search problem where a consumer is initially aware of only a few products. At every point in time, the consumer then decides between searching among alternatives he is already aware of and discovering more products. I show that the optimal policy for this search and discovery problem is fully characterized by tractable reservation values. Moreover, I prove that a predetermined index fully specifies the purchase decision of a consumer following the optimal search policy. Finally, a comparison highlights differences to classical random and directed search.
