| Resumé du document : | Ce travail, qui se limite au segment mobile, sur la période 2001 - 2010, tente d’apporter des éléments de réponse à des questions que généralement le régulateur se pose ; notamment sur l’évolution des revenus des opérateurs -que la seule considération des volumes ne permet d’expliquer-, sur les retombées de la concurrence, et enfin sur l’élasticité de la demande. Il a été mené sur la base exclusive des données publiques des rapports annuels successifs de l’Are. Les résultats obtenus peuvent être affinés et généralisés à d’autres segments grâce à des données plus précises. L’application de la méthode à chacun des opérateurs devrait mieux nous renseigner sur leurs politiques respectives des prix, sur le pouvoir de marché de chacun, et en définitive sur l’effectivité de la concurrence entre eux. Mots clés: Concurrence, chiffre d’affaire, prix, surplus du consommateur, demande, élasticité. |
