Résumé

L'amour lorsqu'il est poussé à son paroxysme confine à l'étouffement. Telle est la morale de cet article dans lequel un parent altruiste module son offre de travail en partie pour assurer le meilleur niveau de vie possible à son enfant. Lorsque le travail des parents et celui des enfants sont parfaitement substituables dans la production, ce comportement pousse les salaires à la baisse. Si les salaires horaires sont rigides, l'emploi est rationné et les jeunes sont les premières victimes de ce rationnement. Nous montrons que ce mécanisme est à l'origine de fluctuations endogènes entre chômage et plein emploi lorsque la productivité des travailleurs âgés est négativement influencée par la durée de chômage passée. Nous analysons également le soutien politique pour le salaire minimum lorsque la productivité des jeunes est soumise à un aléa : le salaire minimum, l'offre de travail des vieux et le chômage des jeunes augmentent tous trois avec le facteur d'altruisme.

Summary

Summary

Love pushed beyond its paroxysm leads to suffocation. That is the moral of this article, which depicts an altruistic parent setting her labour supply to offer the best living conditions to her child. When parents and children are perfectly substituable in production, this behaviour pushes all wages down. If hourly wages are rigid, employment is rationed and the youth are the primary victims of such rationing. We show this mechanism may originate endogenous fluctuations between under and full employment when the older workers' productivity negatively responds to past unemployment. We also analyse the political support for the minimum wage. When the youth productivity is random, the minimum wage, the older workers' labour supply and youth unemployment together rise with the intensity of parental altruism.
