Booking hotels online: can scarcity messages mitigate the effect of a mediocre aggregated eWOM valence?
通过两个实验，研究了稀缺信息类型（限量vs.限时）与聚合电子口碑效价（正面vs.平庸）如何共同影响消费者对酒店价格促销的反应，发现平庸口碑下限量信息更有效。
Purpose This paper aims to examine the interplay of scarcity message type and aggregated electronic word-of-mouth (eWOM) valence in influencing consumer intentions in response to online hotel price promotions. Design/methodology/approach Two experimental studies were conducted, manipulating scarcity message type (limited-quantity vs. limited-time) and aggregated eWOM valence (positive vs. mediocre). Study 1 focused on budget hotels and Study 2 on midscale hotels. Data came from Amazon Mechanical Turk. Findings A positive aggregated eWOM valence always inspired greater confidence than a mediocre one. For midscale hotels, limited-quantity scarcity messages were more effective. However, the type of scarcity did not matter for budget hotels. Moreover, limited-quantity cues consistently worked better than limited-time cues in the mediocre aggregated eWOM valence condition. Practical implications A positive aggregated eWOM valence is obviously preferred to a mediocre one. That said, if a hotel ends up with a mediocre aggregated eWOM valence, it should use limited-quantity scarcity messages to tilt the balance in its favor. Originality/value This work responds to the call for research on the effect of online scarcity messages in tandem with eWOM. Also, it is the earliest attempt to reveal how scarcity messages fare differently for various hotel categories.
