主   题:Beyond Consumption: Do Social Network Friends Turn You into Reviewers? (超越消费:社交网络朋友会将你变成评论者吗?)

主讲人:刘德(明尼苏达大学,副教授)

讲座语言:中英双语

讲座摘要: 

User-generated online reviews play a significant role in consumer decision making but many consumers do not take the next step to provide a review. This research examines the “friend effect” in review generation, i.e. the effect of showing social network friends’ reviews on a focal user’s chance of providing a new review on the same item. Using a combination of observational data on Yelp restaurant reviews and a randomized experiment, we demonstrate that friend reviews increase a user’s chance to provide a new review (thus trigger a form of relational herding), despite a natural competition between friends’ and the focal user’s reviews. Interestingly, the new review tends to be higher quality with prior friend reviews than without. Moreover, the friend effect goes beyond piquing users’ interests – it helps turn interested users to reviewers. These findings establish the friend effect as a novel way of nudging users to write more online reviews, and highlight the value of social-networked production of online reviews.
