Résumé

Dans le but d’analyser le cycle de productivité de l’emploi, cet article présente un modèle de cycles réels avec coûts d’ajustement croisés sur l’investissement et le travail. Le modèle est simulé et confronté aux faits stylisés du marché du travail. Nous évaluons plus particulièrement la capacité du modèle à reproduire un cycle de productivité de l’emploi. Nous montrons alors que l’amplitude du cycle de productivité ne dépend pas uniquement du poids des coûts d’ajustement de l’emploi, mais peut aussi résulter du degré de complémentarité, en termes de coûts d’ajustement, de l’embauche et de l’investissement. Au-delà de son explication du cycle de productivité, le modèle permet aussi de rendre compte de la dynamique de l’investissement et de l’emploi.

Summary

Summary

The aim of this article is to analyse the labour productivity cycle in the context of a real business cycle model augmented by interrelated adjustment costs. The model is simulated and compared to the labour market stylised facts. More specifically, we evaluate the ability of the model to reproduce the labour productivity cycle. We show that the size of the latter not only depends on the weight of the labour adjustment costs, but is also influenced by the existing complementarities of hiring and investment. Beyond the explanation of the productivity cycle, the model is also able to account for the investment employment dynamics.
