Summary

New U.S. evidence from NIPA contradicts some of the well-known Kaldor stylized facts, and call for a reformulation of the modern theory of economic growth. Among these new facts, two must be stressed: A permanent decline in the relative price of durable goods, and a permanent increase in the real equipment to real GDP ratio. To be consistent with these new facts, growth models must include at least two sectors and address the problem of defining aggregate output. In this paper, the economic theory of index numbers is used to define the growth rate of real output in a growth model with embodied technical change. The main findings are: (i) NIPA’s methodology measures growth in accordance with the economic theory on index numbers, and (ii) when the growth rate is measured as in NIPA, the contribution of embodied technical change to per capital GDP growth in the U.S. is 69%, which reinforce the claim that embodied technical change is important for growth.

Résumé

Résumé

De nouvelles statistiques américaines provenant du NIPA contredisent certains des fameux faits stylisés de Kaldor et invitent à une reformulation de la théorie moderne de la croissance économique. Parmi ces faits nouveaux, deux sont à mettre en avant plus particulièrement : une baisse continue du prix relatif des biens durables et une hausse continue du ratio équipement réel sur PIB réel. Pour être en accord avec ces nouveaux faits stylisés, les modèles de croissance doivent inclure au moins deux secteurs et s’attaquer au problème de la définition du produit agrégé. Dans cet article, nous utilisons la théorie économique des nombres-indices pour définir le taux de croissance du produit réel dans un modèle de croissance avec changement technique incorporé. Les principaux résultats sont les suivants : (i) la méthode du NIPA mesure la croissance conformément à la théorie économique des nombres-indices, et (ii) lorsque le taux de croissance est mesuré comme le fait le NIPA, nous trouvons que la contribution du changement technique incorporé à la croissance du PIB par tête aux Etats-Unis est de 69%. Ceci confirme l’hypothèse selon laquelle le changement technique incorporé est important pour la croissance.
