Abstract
This paper evaluates the contribution of cross‐sector allocative efficiency to the productivity slowdown in the US during the 1970s and 2000s. We extend the framework of Oberfield (2013) to derive sufficient statistics for allocative efficiency and decompose aggregate productivity growth in a multisector economy. We find approximately two‐thirds of the productivity slowdown can be explained by the lack of improvement in allocative efficiency. Furthermore, data shows that increased sector‐level volatility is associated with the deterioration of allocative efficiency. Allocation optimale des ressources et ralentissement de la productivité. Cet article évalue la contribution de l'allocation optimale des ressources entre les secteurs au ralentissement de la productivité aux États‐Unis dans les années 1970 et 2000. Nous étendons le cadre d'Oberfield (2013) afin de dégager des statistiques suffisantes pour mesurer l'allocation optimale des ressources et de décomposer la croissance de la productivité globale dans une économie multisectorielle. Nous constatons qu'environ les deux tiers du ralentissement de la productivité peuvent s'expliquer par l'absence d'amélioration de l'allocation optimale des ressources. De plus, les données montrent qu'une volatilité sectorielle accrue est associée à une détérioration de l'allocation optimale des ressources.
