Inégalité, mobilité et hétérogénéité sur le marché du travail : Contribution Empiriques et Méthodiques

Abstract : This dissertation contains three essays devoted to the study of the heterogeneity and the dynamics of individuals on the labor market. The first chapter highlights the link between wage (im-) mobility and the persistence of wage inequality. We use a simple and original statistical method to analyze wage trajectories. We estimate the model on French data for the period 1990-2202. We find that the recession of the early nineties was associated to an increase of the level of longitudinal inequality.
In the second chapter, we study the effect of job-to-job mobility on the correlation between wage and non wage job characteristic. In the model, strong preference for these amenities do not necessarily translate into negative correlation is mobility cost are highlight heterogeneous. On European date, we estimate strong preferences for some amenities such as the type of works or job security, together with small wage differentials between different levels of amenities.
In chapter 3 and 4, we introduce a method to model unobserved heterogeneity : Independent Component Analysis. The letter differ from Principal Component Analysis in that factors are assume statistically independent, and not merely uncorrelated. This additional assumption yields unambiguous identification of factor loadings. We apply the method to French date on wage and education. Our results suggest that the relation between wages and education is complex and multidimensional.
