Review platforms often use transient status reward systems where the granted status is not permanent, and reviewers can experience gains and losses in status. To evaluate the effectiveness of such systems, review platforms need to consider a trade-off between the potential positive effects of a status gain and the potential negative effects of a status loss on the quantity and characteristics of reviewers’ contributions. This article examines this trade-off. The results of an empirical study that uses matched difference-in-differences analysis of data from Yelp show that: (i) the positive effect of a status gain on the number of reviews is about three times greater than the negative effect of a status loss; (ii) these effects are more pronounced for reviewers with less experience; and (iii) status changes also change the valence and elaborateness of reviews.

评论平台通常使用临时状态奖励系统，其中授予的状态不是永久性的，评论者可以体验状态的得失。为了评估此类系统的有效性，评论平台需要权衡地位提升的潜在积极影响和地位丧失对评论者贡献的数量和特征的潜在负面影响。本文研究了这种权衡。使用来自 Yelp 的数据的匹配差异分析的实证研究的结果表明：（i）状态增加对评论数量的积极影响大约是状态损失的负面影响的三倍; (ii) 这些影响对于经验较少的审稿人更为明显；
