“Motivating Online Reviewers through Social Influences: A Dynamic State Space Model”

报告摘要：

This study examines the social incentives for online reviewers to write new reviews.  Drawn upon theories in behavioral science and social psychology we propose two important social influences, social feedback and changes in reputation for online reviewers’ voluntary contributions. We develop a dynamic state space model to quantify the effects from social influences on reviewers’ review motivations and thus their dynamic decisions on whether to write a review.  We find that reviewers respond actively to the changes in social influences.  Interestingly, both positive and negative feedback increase reviewer’s motivation to review and thus increase the propensity for a reviewer to write a new review. Contrary to Deci’s cognitive evaluation theory, receiving negative feedback could have a stronger impact than receiving positive feedback or no social influences in motivating reviewers, especially for experienced reviewers or reviewers who disclose real name identity.  In addition, either increase or decrease in reputation positively affects reviewer’s review motivation and thus increases reviewer’s probability to contribute. Using the estimated model, we find that not providing social feedback or ranking system on a review site could reduce reviewers review propensity by 16.33% and 25.74% respectively for experienced reviewers. We discuss various implications for user motivations, review site designs and strategies.
