Mobilités, inégalités et trajectoires professionnelles

In this paper we present a study on mobility and careers, using a unique panel data set in France. The fh-dads database, resulting from the matching of Pôle Emploi (French National Employment Agency) historical database and dads panel data set, allows us to highlight indeed stability and instability of employment. In order to take into account the presence of unobserved heterogeneity, we use a fixed effect transition model proposed by Magnac [2000] that depicts transitions on the job market. Results reveal the existence of a large heterogeneity in mobility between individuals that cannot be explained by individual characteristics only. This heterogeneity leads to a particular evolution of mobility, sensitive to the economic situation, and linked to the evolution of inequality.
