Abstract

Faut-il augmenter ou baisser les prix pour améliorer la rentabilité d'un grand réseau de transport? La loi de la demande qui stipule une relation inverse entre la quantité et le prix ne peut à elle seule répondre à la question. D'autres paramètres interviennent. Ce dossier propose des modélisations de la fonction " quantité " qui permettent d'évaluer l'élasticité c'est-à-dire les conséquences sur celle-ci d'une variation de la demande.
