Abstract

In this paper, we analyse the consequences of reducing working time on unemployment and growth in an overlapping generations model with negotiated wages, capital accumulation and firms creation. A partial equilibrium analysis shows that a lower working time can raise employment. However, a general equilibrium analysis implies a very different result: a lower working time, by decreasing the number of firms, induces an increase in the unemployment rate. Moreover, there is an "optimal" working time, which maximizes the growth rate. This optimal working time increases with the firms' monopoly power on the goods market. Cet article présente une analyse des conséquences d’une réduction du temps de travail sur le chômage et la croissance dans un modèle à générations imbriquées avec salaire négocié, accumulation du capital et entrée d’entreprises. À l’équilibre partiel, une diminution de la durée du travail peut être favorable pour l’emploi. Par contre, à l’équilibre général, la réduction de la durée du travail entraîne une diminution du nombre d’entreprises qui induit une hausse du taux de chômage. En outre, il existe une durée du travail « optimale », fonction décroissante du degré de monopole sur le marché des biens, qui maximise le taux de croissance.
