KEDGE BUSINESS SCHOOL EXPERT OPINION – 21.09.2017

French chef Sébastien Bras recently renounced his Michelin stars. For good reason, says our expert Olivier Gergaud.

Sébastien Bras, a three-star Michelin chef, has asked to be removed from Michelin's restaurant reference guide in order to free himself from the intense pressure that comes with such an accolade. Olivier Gergaud, economics professor at Kedge Business School, shares his thoughts on the financial and economic consequences for restaurants when they gain or lose a Michelin star.

In his study entitled "Étoiles Michelin : Quel impact économique et financier sur les restaurants ?" (Michelin stars: the economic and financial impact on restaurants), Mr Gergaud shows that "Michelin stars have a big impact on the financial health of the restaurants they seek to honour, and on diners' wallets."

He also outlines his analysis of the situation and highlights the challenges that restaurant owners face:

  • Restaurants that earn a star in the Red Guide generally see their revenue increase about 80% over the next three years.
  • Prices jump 27% on average, except for a certain category of diners.
  • Earning a Michelin star also encourages chefs to build up a lot of capital. They do so in order to build and maintain a reputation of prestige, for both dining room and kitchen, worthy of the Guide's implicit—but very real—requirements.
  • Restaurants that gain a star usually don't see a big improvement in their bottom line. But restaurants that lose a star can take a huge financial hit, sending them into the red.
  • The average decline in profitability may be considerable—on the order of 100% if we only consider the years prior to the 2008 crisis, which also affected the restaurants in the study.

Mr Gergaud adds, "this heavy sanction could explain the level of stress and fatigue felt each year within a profession that anxiously awaits the publication of the new edition of France's most influential restaurant guide."

About the study

The study is based on a sample of 172 Michelin-starred restaurants and 54,272 non-Michelin restaurants (about 1/3 of the total market).

Four editions of the Michelin Guide—2005, 2006, 2007 and 2008—were used to identify restaurants whose financial statements are available in the Diane database (Source: Bureau van Dijk) as at 12 March 2013. The analysis of the effects of promotions and demotions is based on comparable data from a subsample of 15 restaurants promoted or demoted in Michelin's Red Guide between 2003 and 2014.
