Abstract

[fre] L'indice des prix à la consommation fournit, mois par mois, une estimation de l'évolution des prix. Pour les prix alimentaires, une autre estimation annuelle est possible, à partir de données recueillies auprès des ménages. Ces deux estimations, complètement indépendantes, ne s'écartent que de 0,2% pour la période 1970-1982. . Pour certains postes, les deux sources conduisent à des écarts plus importants. Ceux-ci tiennent principalement au fait que les changements dans la structure de la consommation ne sont pas pris en compte de la même façon dans les deux sources. Lorsque la consommation s'est déplacée vers des produits moins chers, comme pour les viandes, la croissance des prix est moins forte selon les enquêtes « Consommation ». Elle est plus forte dans les cas, plus rares, de déplacements vers des produits plus chers. [eng] Evolution of food prices : surveys confirm the index - The purchase price index, month by month, furnishes an estimate of the evolution of prices. Were food prices are concerned, another annual estimate is possible by using data collected from households. These two completely indépendant estimates differ by only 0.2 % for the period 1970-1982. . For certain items, the two sources lead to more significant differences. These differences are the result of the fact that changes in the consumption structure are not taken into account in the same way in the two sources. When the emphasis was shifted towards consumption of less expensive products, such as meats, the increase of prices was less great according to the surveys " Consumption ". It was greater in rarer cases of a shift towards more expensive products. [spa] Evolution de los precios alimentarios las encuestas confirman el indice - El Indice de precios al consumo facilita mensualmente una estimación de la evolución de los precios. Para los precios alimentarios es factible otra estimación anual a partir de datos recogidos cerca de los hogares. Ambas estimaciones, totalmente independientes, distan tan solo de un 0,2% para el periodo de 1970-1982. . Respecto a ciertos renglones, ambas fuentes llevan a descartes de más importancia. Estos se desprenden del hecho de que los cambios intervenidos en la estructura del consumo no se toman en cuenta del mismo modo en ambas fuentes. Cuando el consumo se ha orientado hacia productos menos costosos, tal como sucede para con la carne, el alza de los precios se éleva menos segùn las encuestas de consumo, Es mayor en los casos, menos corrientes, de cambios por productos más caros.
