This work intends to study the implication of an editorial review program where a review platform starts to supplement the user-generated reviews on its website with editorial review articles that are written by the platform. Our research question is whether platform-generated content (i.e., editorial reviews) influence subsequent user- generated content (i.e., online reviews) both in terms of the quantity and quality of those reviews. We obtain the dataset through a partnership with a restaurant review platform in Asia. Our preliminary analysis suggests that platform-generated content has a positive net effect on subsequent user-generated content. Specifically, users post more reviews for restaurants that have editorial reviews and these reviews tend to be longer on average.
