 \n\nThe Experts and the Crowd? Heterogeneity in Status and the Behavior of
  Amateur Reviewers\n\nDate: Friday\, April 17\, 2026\n	Time: 10:30 AM - 12:

 ct\n\nNowadays\, amateur reviewers and professional critics coexist in man
 y markets and express their opinions on the same producers and offerings. 
 To what extent should we expect the evaluations provided by consumers to c
 onform to those provided by professional critics? And are all consumers eq
 ually subject to such conformity pressure? To examine these questions\, we
  exploit a fortuitous partnership between Michelin\, the editor of the mos
 t prestigious restaurant guide\, and TripAdvisor\, a prominent aggregator 
 of consumer reviews for the restaurant industry. As a result of this partn
 ership\, the TripAdvisor pages of restaurants evaluated by the Michelin Gu
 ide were updated with a Michelin badge under the restaurant name and a dir
 ect link to the evaluation by Michelin inspectors. Using a difference-in-d
 ifferences approach\, we examine changes in reviews posted on TripAdvisor 
 before and after the appearance of the Michelin evaluation relative to rev
 iews posted on Yelp\, a similar platform that did not introduce any Michel
 in-related information. Our results reveal that amateur reviewers signific
 antly changed their evaluations when the opinion of experts became more sa
 lient. The change was reflected in both the form and substance of their re
 views\, with differential treatment effects depending on the status of the
  amateur evaluators on the review platform.\n
