[fre] Nous évaluons de façon conjointe les différences de productivité et de rémunération existant en France entre diverses catégories de travailleurs au moyen d'une nouvelle base de données qui réunit des informations tant sur les employés que sur leurs employeurs. Complétant une méthodologie nouvelle proposée au départ par Heller- stein, Neumark et Troske [1999], nous adoptons des hypothèses moins contraignantes et fournissons une méthode utilisant le coût du travail pour les employeurs. De façon surprenante, les résultats trouvés pour la France sont très différents de ceux obtenus pour les Etats-Unis, et plus proches des résultats en Norvège : dans le secteur manufacturier, nous constatons que les travailleurs âgés sont plus payés par rapport aux travailleurs jeunes que leur différence de productivité ne le laisserait supposer. La robustesse de ces résultats semble confirmée à travers le temps, les secteurs d'activité et les hypothèses retenues. [eng] In this study we analyse the differences between productivity levels and earnings across a range of categories of workers in France, drawing on a new database which brings together data from employers and employees. We take as our starting point the methodology first introduced by Hellerstein, Neumark and Troske [1999], and develop it further by applying les restrictive assumptions and by using a new method which takes into account labour costs incurred by the employers. The results obtained for France are surprisingly different to those for the United States and in fact are closest to the results obtained for Norway. For example, we find that in the manufacturing sector, relatively to younger workers, older workers are paid more than the difference in productivity between the two age groups would suggest. These results appear to be robust over time regardless of the sector studied or the assumptions used.
