Abstract

[fre] Le rôle de l'hétérogénéité des agents sur un marché du travail en concurrence imparfaite. . Nous considérons deux modèles où à la fois les travailleurs et les emplois sont hétérogènes et où le marché du travail est en concurrence imparfaite. La différence entre ces deux approches repose essentiellement sur la nature de l'hétérogénéité envisagée et donc sur la manière dont l'appariement entre travailleurs et emplois est réalisé. Dans le premier modèle, les individus et les entreprises sont différenciés par leur type de spécialisation alors que dans le second l'hétérogénéité repose sur des niveaux distincts de qualification. Nous étudions alors les propriétés de ces deux modèles et nous les comparons. Nous montrons en particulier que les politiques d'emploi sont soient ciblées soient plus systématiques selon le contexte d'appariement. [eng] The role of agents' heterogeneity in an imperfect labor market. . We consider two models where both workers and firms are heterogeneous and where the competition in the labor market is imperfect. The main difference between these two approaches is the type of heterogeneity considered and the nature of job matching. In the first model, workers and firms are differentiated by their type of specialization whereas in the second one the heterogeneity is due to differences in qualification levels. We then study the properties of the two models and we compare them. We show in particular that employment policies are either local or more systematic depending on the type of job matching.
