讲座内容摘要

阈值效应在消费者选择行为与企业运营管理中扮演着重要角色。一种阈值可以是保留价值，消费者不会考虑任何效用低于该阈值的产品。消费者也可以通过移除那些效用低于最大效用一定阈值的产品来形成其考虑集。此外，传统选择模型可被扩展以适应多次购买的情形，即消费者考虑或购买所有净效用超过某一阈值的产品。因此，阈值效应可能对企业运营管理（如品类规划和定价）产生显著影响，尤其是面对异质性消费者时。在本次讲座中，我们将展示若干场景，在这些场景中，阈值效应下的消费者选择行为可被刻画，且企业的最优或近似最优运营策略也能被高效推导。我们的分析表明，对阈值效应的错误设定可能导致重大损失。

Threshold effects play important roles in consumers’ choice behavior and firms’ operations management. A threshold could be the reservation value, and a consumer does not consider any product whose utility is below this threshold. A consumer could form her consideration set by removing the products whose utility is lower than the largest by another threshold. Moreover, the traditional choice model could be generalized to accommodate multiple purchases, in which a consumer considers or purchases all products whose net utility exceeds a certain threshold. Consequently, threshold effects may have a significant impact on firms’ operations management such as assortment planning and pricing, especially with heterogenous consumers. In this talk, we showcase several scenarios, in which consumers’ choice behavior under threshold effects can be characterized, and the firm’ optimal or near-optimal operations strategy can also be derived efficiently. Our analysis shows that misspecification of threshold effects may lead to significant losses.
