“…The model presented in this article could be refined in many different ways: for instance, with a similar model but without seasonal production, with a noncompetitive inventory holding market, and perhaps with a household model of on‐farm storage. However, it should be noted that we have studied elsewhere other versions of the nonlinear cobweb model with private storage, for example with naive instead of adaptive expectations, 15 with one agent producer‐inventory holder (Mitra, 2001) and with a linear instead of a nonlinear demand curve (Mitra and Boussard, 2011). These different versions of the model could also lead to irregular price movements and reproduce some of the empirical characteristics of actual price series.…”

“…Ainsi, les exportations de l'AOC croissent dans une proportion moindre que les exportations du Monde comme le témoigne le graphe N°12 ci-dessus, ce qui fait régresser la part de marché. L'AOC se trouve plus pénalisée par cette volatilité structurelle et inévitable (voir chapitre précédent) parce qu'elle n'a développé en son sein aucune solution palliative pouvant lui permettre de réduire les effets induits que confirment Mitra et Boussard (Mitra & Boussard, 2011).…”

“…La qualité et la quantité produites résultent d'un ensemble d'événements naturels non contrôlés par le producteur (MOSCHINI et HENNESSY, 2001). Par ailleurs, le prix du produit n'est généralement pas connu au moment où les décisions de production doivent être prises, les chocs sur l'offre globale (sécheresses, inondations, zoonoses), et pour certains auteurs les comportements des agents économiques, contribuant à accroître l'incertitude et la volatilité des prix agricoles (MITRA et BOUSSARD, 2011).…”
