International Interactions in Food and Agricultural Policies: The Effect of Alternative Policies

This paper presents a model of longer term interactions in the international markets for cereals, soybeans and meat, and draws policy conclusions for developing countries. The model is comparative static in nature and, largely, partial equilibrium, incorporating constant elasticity demand and supply functions. It is an extension of earlier similar models: commodity interdependence is modelled explicitly and long-run effects, of productivity growth on domestic production and of income growth on demand, are incorporated. Moreover, demand for feed, as derived from livestock production, is separated from food demand. The focus is on policy analysis and on developing countries. The results are somewhat surprising. First, real prices of wheat and coarse grains would continue to fall under liberalisation assumptions. Second, developing countries' agricultural policies emerge as more important (in relation to OECD countries' policies) than expected, and as ... Ce document présente un modèle d'interactions à moyen terme des marchés internationaux des céréales, du soja et de la viande et établit des conclusions sur le plan de l'action à suivre pour les pays en développement. C'est un modèle de statique comparative et, pour l'essentiel, d'équilibre partiel comprenant des fonctions de demande et d'offre à élasticités constantes. C'est un développement de modèles similaires antérieurs : l'interdépendance des produits de base est modélisée explicitement et les effets à long terme de la croissance de la productivité sur la production intérieure ainsi que ceux de la croissance du revenu sur la demande sont pris en compte. De plus, la demande pour l'alimentation destinée au bétail telle qu'elle est dérivée de la production du bétail, est séparée de la demande pour l'alimentation humaine. L'accent est mis sur l'analyse des grandes orientations et sur les pays en développement. Les résultats sont plutôt ...
