This paper explores the effect of expert opinions on consumer experience via the lens of consumer reviews in the restaurant industry, where the expert opinions are conveyed by Michelin stars. The paper uses a unique data set based on the Michelin Guide for Great Britain &amp; Ireland from 2010 to 2020. The data include consumer reviews on TripAdvisor for all restaurants that were awarded Michelin stars during this period and a large pool of potential control restaurants. We apply two synthetic control\u2013based methods to estimate the effect of Michelin star changes on the sentiment and content of consumer reviews. We find that decreases in Michelin stars improve consumer review ratings. We examine three potential explanations for this finding. First, the positive expectation effect of lowered expert opinions outweighs the negative reputation effect. Second, there could be a change in the customer mix. Third, there may be a changes on the supply side, for example, in service levels. We find support for the first explanation, rule out the second, but cannot entirely rule out the third. The analysis of review content further shows that a loss in Michelin stars leads consumers to become less focused on value and become less demanding regarding service. We discuss the implications of our findings for restaurant managers, the Michelin Guide, and other businesses that provide experience goods.<\/jats:p>\n                  <jats:p>This paper was accepted by Eric Anderson, marketing.<\/jats:p>\n                  <jats:p>Supplemental Material: The online appendices and data files are available at https:\/\/doi.org\/10.1287\/mnsc.2023.04302 .<\/jats:p>","DOI":"10.1287\/mnsc.2023.04302","type":"journal-article","created":{"date-parts":[[2025,7,28]],"date-time":"2025-07-28T14:12:25Z","timestamp":1753711945000},"page":"2427-2450","source":"Crossref","is-referenced-by-count":2,"title":["Can Lower(ed) Expert Opinions Lead to Better Consumer Ratings?: The Case of Michelin Stars"],"prefix":"10.1287","volume":"72","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9875-0165","authenticated-orcid":false,"given":"Xingyi","family":"Li","sequence":"first","affiliation":[{"name":"Ontario Teachers\u2019 Pension Plan, London W1H 6AZ, United Kingdom"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2330-1554","authenticated-orcid":false,"given":"Yiting","family":"Deng","sequence":"additional","affiliation":[{"name":"UCL School of Management, University College London, London E14 5AA, United Kingdom"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2013-612X","authenticated-orcid":false,"given":"Puneet","family":"Manchanda","sequence":"additional","affiliation":[{"name":"Ross School of Business, University of Michigan, Ann Arbor, Michigan 48109"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7991-6350","authenticated-orcid":false,"given":"Bert","family":"De Reyck","sequence":"additional","affiliation":[{"name":"Lee Kong Chian School of Business, Singapore Management University, Singapore 178899, Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"109","reference":[{"key":"B1","doi-asserted-by":"publisher","DOI":"10.1198\/jasa.2009.ap08746"},{"key":"B2","doi-asserted-by":"publisher","DOI":"10.18637\/jss.v042.i13"},{"key":"B3","doi-asserted-by":"publisher","DOI":"10.1111\/ajps.12116"},{"key":"B4","doi-asserted-by":"publisher","DOI":"10.1287\/mksc.2022.1375"},{"key":"B5","doi-asserted-by":"publisher","DOI":"10.1017\/S1931436100001085"},{"key":"B6","doi-asserted-by":"publisher","DOI":"10.1257\/aer.20190159"},{"key":"B7","doi-asserted-by":"publisher","DOI":"10.1038\/scientificamerican1155-31"},{"key":"B8","doi-asserted-by":"publisher","DOI":"10.1017\/jwe.2013.22"},{"key":"B9","doi-asserted-by":"publisher","DOI":"10.1287\/mksc.2022.1352"},{"key":"B10","doi-asserted-by":"crossref","unstructured":"Bondi T, Rossi M, Stevens R (2023) The good, the bad and the picky: Reference dependence and the reversal of product ratings.
