Abstract

Date de réception de l'article : 5 janvier 2004 Date d'acceptation pour publication : 1 er juin 2004 RÉSUMÉ. La présente étude explore une piste particulière d'explication du retard européen dans la diffusion des TIC, vis-à-vis des États-Unis : celle d'une plus faible élasticité-prix (en valeur absolue) de leur demande. L'analyse porte conjointement sur cinq pays : la France, l'Allemagne, les Pays-Bas, le Royaume-Uni et les États-Unis. Les données mobilisées sont macroéconomiques, annuelles, et couvrent la période 1975-2001. Le retard européen ne s'explique pas par des écarts, entre pays, des élasticité-prix de la demande des différents produits TIC. Une part au moins des écarts de diffusion des TIC trou-verait son origine dans des différences plus structurelles. Enfin, la valeur estimée de l'élasti-cité-prix des matériels informatiques et des logiciels est généralement inférieure à – 1, ce qui explique, compte tenu de la baisse du prix relatif de ces produits, la croissance de leur part dans l'ensemble des dépenses d'investissement ou dans le PIB. Une telle situation, caractéris-tique d'une étape de diffusion de ces produits, ne peut être que transitoire Classification JEL : E22 ; O47 ; O57 ; R34.

This study explores a particular way of explaining the lag between Europe and the United States in the diffusion of ICT, namely that of Europe's weak (in absolute terms) price elasticity of demand. The study looks at five countries: France, Germany, the Netherlands, the United Kingdom and the United States. Annual macroeconomic data is used for the years 1975-2001. The results indicate that Europe's backwardness cannot be explained by spreads, between countries, in the price elasticity of demand for various ICT products. At least part of the spreads in ICT diffusion is structural. The estimated value of the price elasticity for ICT hardware and software is generally less than – 1. This explains why their s
