Abstract

Nous analysons l'impact et les déterminants d'une taxe carbone globale dans une économie imparfaitement intégrée composée de pays de différente taille. A l'aide d'un modèle de commerce et de localisation, nous montrons tout d'abord que la concentration de firmes dans le pays disposant d'un avantage de taille de marché accroît les émissions totales de CO2. L'intro- duction d'une taxe carbone globale conduit alors à des délocalisations de fi rmes du grand pays vers le petit pays de sorte que même fixée à un taux unique, une fiscalité carbone ne serait pas neutre du point de vue de la géographie économique. Enfin, parce qu'elles conduisent à une réduction des émissions mondiales de CO2, ces relocalisations améliorent l'efficacité environnementale de la taxe carbone.
