Abstract

Le ralentissement des gains de productivité par tête observé depuis la fin des années 80 en Europe, et notamment en France, est susceptible de plusieurs types d'interprétations. Il pourrait refléter un tassement des gains de la productivité globale des facteurs, une substitution des têtes aux heures ou un rééquilibrage des productivités apparentes des différents facteurs de production. L'objet de cet article est de souligner le rôle de ce mouvement de rééquilibrage, en réponse à une baisse du coût relatif du travail, notamment peu qualifié. Dans cette perspective, la baisse des gains de productivité par tête, loin d'être défavorable, refléterait un enrichissement de la croissance en emploi dans un contexte de décrue du chômage structurel. Nous illustrons les mécanismes sous-jacents en nous appuyant sur un modèle d'offre et de demande de travail à deux qualifications. La version dynamique du modèle est calibrée afin de donner une image des évolutions temporelles de la production, de l'emploi, ainsi que des productivités apparentes des facteurs en réponse à des chocs de coûts.
