Abstract

[fre] Nous établissons le degré optimal pour le producteur de la stabilisation du prix des produits agricoles d'exportation dans le cadre de systèmes de prix minimum garanti et de marge de fluctuations autorisées. Nous montrons que le producteur a toujours intérêt à constituer une épargne de précaution puisqu'il n'est pas opti­mal d'éliminer complètement le risque de prix.. Nous déduisons du modèle les effets d'un accroissement de certains types de risque de prix sur l'arbitrage entre épargne de précaution et stabilisation des prix. [eng] This paper examines the optimal degree of agricultural export produce prices stabilization within two systems : a minimum guaranteed price and an authorized fluctuations margin. The producer always saves for precautionary purposes as integral stabilization is suboptimal. A static comparative analysis shows how mean preserving increases in risk affect the optimal choice between private insurance against risk (precautionary saving) and parastatal stabilization.
