Abstract

Pandémies, réchauffement climatique, sécurité alimentaire, vieillissement, épuisement de certaines matières premières… Nos économies sont confrontées à des problèmes globaux, convoquant le long terme et posant des questions intergénérationnelles. Pour guider les politiques économiques, il est dès lors indispensable de disposer d’un cadre de réflexion cohérent. Le modèle MaGE (pour Macroeconometrics of the Global Economy), développé par le CEPII, permet de dessiner les tendances de fond de l’économie mondiale à l’horizon 2050. Si l’on suppose que les dynamiques de croissance et de rattrapage technologique actuelles vont se poursuivre, et compte tenu des dynamiques démographiques, l’équilibre des puissances économiques sera fortement transformé au cours de la génération à venir. Surtout, la consommation d’énergie devrait continuer de croître à un rythme soutenu jusqu’à doubler, en dépit des efforts en matière d’efficience énergétique. Des politiques ambitieuses de décarbonation de nos économies seront alors nécessaires pour rendre soutenables les perspectives de croissance économique.
