Abstract

Ce document propose un cadre d'analyse pour examiner les effets sur les marchés et les effets en terme de bien-être des organismes génétiquement modifiés (OGM), lorsque certains consommateurs refusent les OGM et lorsque deux filières de production sont séparées, l'une pour des produits contenant des OGM et l'autre pour des produits non OGM à identité préservée. Le cadre analytique part du niveau individuel pour les agriculteurs, les transformateurs et les consommateurs, pour construire les fonctions d'offre et de demande agrégées. Ceci permet de contourner les difficultés liées à l'analyse offre-demande dans les différents marchés horizontaux et verticaux concernés par les OGM et la ségrégation des marchés. Le cadre repose sur une représentation explicite des coûts de ségrégation à la fois pour les producteurs de biens avec OGM et pour les producteurs de biens non OGM à identité préservée, et de la variation de ces coûts selon la taille relative des deux filières. Le modèle est illustré par une simulation sur l'adoption potentielle de colza OGM dans l'Union européenne, en présence d'une ségrégation OGM-non OGM. Les auteurs examinent comment les coûts de ségrégation sont distribués entre les différents types de producteurs, de transformateurs et de consommateurs dans cette simulation.
