Abstract

[eng] This paper is based on Prebisch and Singer’s work on the deterioration in the terms of trade of developing economies. Using a game-theory model, we can explain the decline in the cocoa-bean price relative to the price of chocolate bars in the French market. One implication of the model is that the price of the raw material and the price of the end product depend respectively on the market power of the main world producer, Côte d’Ivoire, and of the manufacturers. We use an equation system to test for this market power. The results lead us to distinguish two modes of price formation. In the period 1960-1985, Côte d’Ivoire played a dominant role. Market power then gradually shifted from the country to the manufacturers. [fre] Ce travail s’inscrit dans le prolongement des travaux de Prebisch et Singer sur la dégradation des termes de l'échange des pays en développement. Un modèle de théorie des jeux visant à expliquer la détérioration du prix de la fève de cacao par rapport à celui de la tablette de chocolat observée sur le marché français, est proposé. Une implication du modèle est que les prix de la matière première et du produit fini dépendent du pouvoir de marché respectif du principal producteur mondial, la Côte d’Ivoire, et des industriels du cacao. Il en découle un système d’équations permettant de tester le pouvoir de marché de la Côte et des industriels. Les résultats économétriques amènent à distinguer deux régimes de formation des prix. Dans la période 1960 – 1985, la Côte d’Ivoire joue un rôle dominant . Elle perd ensuite progressivement son pouvoir de marché au profit des transformateurs.
