Séminaire MEDP : Tasting, Grading and Ranking Wines

publié le , mis à jour le

Intervenant : Victor Ginsburgh de l’ECARES, Université Libre de Bruxelles, et du CORE, Université Catholique de Louvain
Date et Heure : 15 mars 2016 à 17h
Lieu : Lille 1, Faculté des Sciences Economiques et Sociales, Salle du Conseil

Victor Ginsburgh présentera une communication sur le classement des vins où sont utilisées notamment des méthodes issues de travaux sur la valeur de Shapley.
"The paper deals with judgments of wines by “experts”. I describe classical ranking methods, and using the celebrated Judgment of Paris held in 1976 in Paris (France !), I show that a slightly different method would not have provoked the “scandal” that some unknown Californian wines won against French Grands Crus Classés, which was probably the starting point of a deep change in the world of wines dominated by France at the time. I will then go to wine competitions at large, and give some evidence that the rankings that result are all but serious. Finally, I will suggest a new method based on the Shapley value that may be better, since it is based on serious axioms and makes it easier for judges to rate wines."
