      "fr" => "Dans cet article, nous résolvons le problème du contrôle optimal de la diffusion des produits par la qualité et l'investissement publicitaire. En ce sens, nous utilisons une fonction de demande dynamique s'appuyant sur deux hypothèses : en premier lieu, le prix est un signal de qualité fiable , d'autre part, la demande exprime une préférence pour la qualité par rapport au prix. La résolution du problème posé par le principe du maximum de Pontryagin nous conduit alors à caractériser les trajectoires dynamiques optimales respectives de la qualité, de l'effort publicitaire et du prix, ainsi que les conditions de validité de ces dernières."
      "en" => "In this paper, I solve the problem of an optimal control of innovations diffusion both by advertising and quality. To do so, I introduce a dynamic demand function leaning on two hypotheses : first, price seems to be a signal of quality , second, demand is more sensitive to quality than to price. Using the maximum principle of Pontryagin, I then characterize the optimal dynamic trajectories of quality, advertising and price, and their qualitative properties."
