[eng] Productivite and growth what is the long run relation-ship? Bringing together brechling's And Kaldor-Verdoorn's models brigitte Dormont The present sttidy deals with the estimation of the two well-known models of the productivity — growth relationship : Brechling s labor demand equation and the Kaldor-Verdoorn equation. Those two modela are in principle different, concerning respectively short-run and long-run phenomenon. Using panel data of firms, we show that both specifications do not effectively differ, and that the Kaldor-Verdoorn equation can be reinterpreted as a Brechling's labor demand function. Furthermore it is shown that the estimates of productivity-growth elaticity are rather instable and dépendant on the exact formulation of the model adopted. One should be very careful in using them for long-run analysis. [fre] Le présent article étudie sur données d'entreprises deux modèles couramment invo­qués à propos des relations productivité-croissance : la fonction de Brechling et la relation de Kaldor-Verdoorn. Leurs « vocations » sont en principe distinctes et concernent respectivement les analyses clé court terme ou celles de moyen-long terme. On montre ici que la relation Kaldor-Vercloorn ne fournit pas d'explication originale de l'évolution de la productivité à moyen-long terme, par rapport aux traditionnelles fonctions d'emploi définies par Brechling. La mise en évidence clé grandes instabilités des estimations des fonctions d'emploi vis-à-vis des spécifications adoptées incite d'ailleurs à une grande prudence quant aux jugements émis concernant les relations productivité-croissance.
