活动简介:

As online review platforms have allowed people to easily access others’ opinions, potential consumers use the information displayed on these platforms to form pre-purchase expectations. In order to help consumers quickly categorize service providers into multiple levels (such as the 5-star categorization), it is now common for platform providers to display the rounded average rating. However, this rounding strategy may create a discrepancy between pre-purchase expectations and the experienced true quality when the displayed rating is different from the true average rating. Such a discrepancy may affect the consumer’s satisfaction level, which would eventually influence subsequent rating decision and review behavior. This study aims to examine the causal impact of the display of the rounded rating on subsequent rating decisions and the provision of emotional text in a subsequent online review, especially when the displayed rating differs from its true average. Using online review data collected from Yelp, we utilize a regression discontinuity design by taking advantage of Yelp’s rounded rating display. Our primary results suggest that a rounded-up rating (compared with a rounded-down rating) leads to a sharp decrease in subsequent ratings, as well in as the provision of pleasant emotions, but a sharp increase in the provision of unpleasant emotions. Furthermore, we examine the moderating effect of prior reviews’ rating dispersion and information diversity. When prior ratings are consistent, or when the content in prior reviews covers diverse topics, the main impact of the displayed rating would be intensified.
