Abstract

The development of purchasing power parities as converters of national accounts aggregates to comparable volume figures is important for international economic comparisons. This study is primarily concerned with the aggregation of price relativities to basic heading level: that is, the level below which there are no expenditure weights available across all of a given group of countries. Eight possible methods of aggregation to basic heading level are identified and appropriate summary statistics developed to assist in the subsequent practical investigation of these methods. This is undertaken using price data for 37 basic headings in ten OECD countries ... Pour les comparaisons économiques internationales il est important de développer les calculs de parités de pouvoir d'achat. En effet, ces parités permettent de convertir les agrégats de comptabilité nationale et donc de disposer de chiffres en termes réels qui sont comparables de pays à pays. Cette étude porte principalement sur les problèmes d'agrégation des prix relatifs des biens ou services individuels jusqu'au niveau des rubriques de base, c.a.d. le niveau le plus fin pour lequel une pondération par la dépense est disponible, pour tous les pays comparés. L'étude montre que huit méthodes différentes d'agrégation peuvent être employées et propose des mesures statistiques pour examiner les avantages et inconvénients de chacune de ces méthodes en pratique. Les données sur les prix de 37 rubriques de base dans dix pays de l'OCDE sont utilisées pour tester les différentes méthodes d'agrégation ...
