Abstract

[fre] Instabilité des prix et protectionnisme caractérisent le marché mondial du sucre. Après avoir souligné les spécificités de ce marché, les hypothèses, les résultats et les limites de deux modèles de la filière sucre mondiale sont analysés. La prise en compte de l'impact de l'instabilité des prix sur les décisions des agents peut modifier considérablement les résultats de la libéralisation des échanges de sucre, plaidant pour une meilleure représentation des fonctions d'offre dans les modèles utilisés au cours des négociations de l'omc. [eng] Price volatility and protectionism are main features of the world sugar market The assumptions, results and limits of two models of the world sugar market are analyzed. Taking into account the consequences of price volatility on agents decision making may radically change expected results of sugar trade liberalization, underlying the need to improve supply functions representation in models used during wro negotiations.
