    Abstract

    [eng] The influence of product diffusion and product differentiation on the dynamics of market share: . an application to the French market for seed maize . by Stéphane Lemarié . Empirical analysis of differentiated markets has been the subject of growing interest in the past ten years. Using a simple reduced-form model, the author brings out various significant factors that had not previously been highlighted: the impact of the age of the product during the first stages of diffusion, the impact of a technical accident, the impact of the scale of the firm offering the product. The model is applied to the French seed maize market for the whole of the period 1976-1994. [fre] L'influence de la diffusion et de la différenciation des produits sur la dynamique des parts de marché : une application au marché français des semences de maïs . par Stéphane Lemarié . Les analyses empiriques sur les marchés différenciés connaissent un essor important depuis dix ans. À partir d'un modèle simple en forme réduite, nous mettons en évidence différents facteurs significatifs qui n'avaient pas été mis en évidence jusque là : l'effet de l'âge du produit pendant les premières périodes de diffusion, l'effet d'un accident technique sur le produit, l'effet de la taille de l'entreprise qui propose le produit. Le modèle est appliqué au marché français des semences de maïs pour l'ensemble de la période 1976-1994.
