Les prix agricoles et leur évolution différenciée dans chaque pays se justifient-ils économiquement ?

[eng] The green parity system, which was widely criticized in France, defended by a number of other countries and considered neutral by the Commission, caused such a variety of reactions that this alone was reason enough to look into the matter more deeply. Our main concern was to establish whether there is any real economic justification for the differential development of prices in agriculture which the introduction of green rates has brought about within the different Common Market countries. The answer would seem to be yes, in theory, as long as agriculture is developing in a different economy in each country. Having said this, however, the differential development of agricultural prices from one country to another within the Community has put certain member states at an economic advantage and others at a disadvantage because of poor management of the green parity system. The analysis was carried out by comparing trends in selected products in Germany, Great Britain, Italy, the Netherlands and France. [fre] Le système des parités vertes suscite des positions diverses. La question essentielle est de savoir si l'évolution différenciée des prix dans chaque pays de la Communauté se justifie-t-elle économiquement. La réponse apportée est oui théoriquement, si les agriculteurs évoluent dans des économies différentes. Ceci étant dit, l'évolution différenciée des prix agricoles constatée entre un certain nombre de pays de la Communauté a engendré des avantages (ou désavantages) économiques entre Etats-membres du fait d'une mauvaise gestion du système des parités vertes. L'analyse a été réalisée en comparant les évolutions entre l'Allemagne, la Grande-Bretagne, l'Italie, et la France pour quelques produits.
