Abstract

[fre] Le modèle d'échanges commerciaux, . par Jean Mathis et Jacques Régniez. . Mec 2 est un modèle du commerce extérieur de la France en six produits destiné à être utilisé dans le cadre de la préparation des budgets économiques. La modélisation du commerce extérieur des trois produits industriels (biens intermédiaires, biens d'équipement et biens de consommation) fait intervenir les capacités de production, les demandes (intérieures et extérieures) et des variables de prix relatifs. Les estimations conduisent à une très forte substituante entre la demande intérieure et le solde extérieur. Un milliard de plus de demande d'un produit se traduit par un déficit du commerce de ce même produit de, respectivement, 0,6, 0,8 et 0,5 milliard. . Le commerce extérieur en produits agricoles et des industries agroalimentaires est modélisé en solde (et non séparément en exportations et importations); celui-ci dépend de l'excédent de la production par rapport à la demande intérieure et de la plus ou moins grande utilisation des capacités de stockage existantes. . Différents effets variantiels sont présentés qui font ressortir, en particulier, la baisse d'efficacité de la dévaluation (en terme d'effets sur le solde en valeur) depuis la hausse du prix de l'énergie. [eng] The French «Foreign trade» model (Mec 2), by Jean Mathis and Jacques Régniez. . Mec 2 is a French six-product foreign trade model intended for use in the preparation of economic budgets. Modelization of foreign trade for the three main industrial products (intermediate goods, capital goods, consumer goods) brings into play production capacities, demands (domestic and foreign) and relative price variables. Estimates show a massive substitutability between domestic demand and the foreign balance. One billion francs more in demand for a product results in a trade deficit for this same product of 0.6, 0.8 and 0.5 billion francs, respectively. . Foreign trade in agricultural products and processed foodstuffs is modelized as a balance (and not separately as exports and imports). This balance depends upon the surplus of production over domestic demand, and upon the greater or lesser utilization of existing storage capacities. . Different variant effects are presented, which in particular bring out the drop in the efficiency of devaluation (in terms of effects on the balance in values) ever since the rise in the price of energy.
