      "fr" => "Cet article résout un problème de diffusion de produit par sa qualité, utilisant le contrôle optimal dans un contexte de compétition monopolistique. Pour cela, nous introduisons une fonction de demande dynamique reposant sur deux hypothèses. Dans une première, le prix agit comme signal de la qualité. Dans une deuxième, la demande est plus sensible à la qualité qu'au prix. On utilise finalement le Principe de Pontryagin afin de déterminer les trajectoires optimales de la qualité et ses propriétés."
      "en" => "In this paper, we solve the problem of optimal control of quality-driven product diffusion in a context of monopolistic competition. To do so, we introduce a dynamic demand function leaning on two hypotheses : first, price acts as a signal of quality, second, demand is more sensitive to quality than to price. Using the maximum principle of Pontryagin, we then characterize the optimal dynamic trajectory of quality and its qualitative properties."
