[fre] La possibilité d'une transmission asymétrique du prix à l'expédition vers le prix au détail est étudiée pour deux filières importantes du secteur des fruits et légumes : tomate et endive. La disponibilité de données de prix hebdomadaires très détaillées autorise un traitement de cette question à des niveaux très désagrégés. Ce traitement repose sur la mise en œuvre de tests de cointégration avec seuils récemment proposés dans la littérature. Nos résultats ne corroborent pas l'affirmation commune selon laquelle les hausses de prix à l'expédition sont répercutées plus rapidement par la distribution dans les prix au détail que les baisses de ces mêmes prix à l'expédition. Un tel résultat a déjà été mis en évidence pour d'autres pays. Il semblerait être lié au caractère hautement périssable des produits considérés. [eng] Price transmission in the french fresh vegetables channel : an application of threshold cointegration tests - The existence and the kind of asymmetry that characterize the relationships between shipping- point and retail prices are investigated for two major French fresh vegetables: tomatoes and chicory. Weekly data allow considering these relationships at very detailed levels such as region or supermarket chain. Moreover, the methodology proposes an implicit treatment of asymmetries in price transmission by using recently developed threshold cointégration methods. Our results do not give evidence to the widespread assertion that shipping-point price increases are completely and rapidly passed by middlemen on to consumers while there is a slower and less complete transmission of shipping-point price declines. As already emphasized in the literature, these results may be linked to the perishable nature of the two considered fresh vegetables.
