Economists often compare two ways of work sharing: increase of part-time work and the reduction of the weekly work time. Most of the literature focuses upon the labour demand size. The aim of this paper is to tackle this question from the point of view of labour supply. We calibrate on French data a sequential job search model, which as two specific features: the characterization of job offers in terms of utility level which combines hourly wage rates with available leisure time and the fact that unemployment is not the only compatible state with a job search. Simulations of the model show that, for a given labour demand, the probability to be unemployed increases with the proportion of part-time jobs and decrease with the reduction of the weekly work time.
Ce papier examine les effets d’une inflation anticipée dans un modèle à croissance monétaire avec offre endogène de travail et côuts de liquidité. La superneutralité de la monnaie dépend dans ce contexte de la fonction d’utilité. Différentes fonctions d’utilité sont examinées. Contrairement à d’autres approches avec offre de travail endogène, nos résultats montrent une “équivalence qualitative” de l’effet négatif de l’inflation sur le capital et le travail.
