In this paper, we investigate whether business cycles can imply sizable effects on average unemployment. First, using a reduced-form model of the labor market, we show that job finding rate fluctuations generate intrinsically a non-linear effect on unemployment: positive shocks reduce...

This paper extends the job creation - job destruction approach to the labor market to take into account the life-cycle of workers. Forward looking decisions about hiring and firing depend on the time over which to recoup adjustment costs. The equilibrium is typically featured by increasing...

This paper shows that optimal unemployment insurance contracts are age-dependent. Older workers have only a few years left on the labor market prior to retirement. This short horizon implies a more digressive replacement ratio. However, there is a sufficiently short distance to retirement for...

It is often argued that the tax on continued work should be removed by implementing actuarially fair schemes. However, these schemes cannot help fund the expected Social Security deficit. This paper proposes to give individuals only a fraction of the marginal actuarially fair incentives in case...

Cette étude analyse la dynamique des flux de travailleurs au cours du cycle conjoncturel à partir de deux types de données : l'enquête Emploi de l'Insee et les listes de demandeurs d'emploi inscrits à Pôle emploi. Des transitions mensuelles sur le marché du travail sont ainsi construites...

[eng] This paper studies the impact of the progressivity of income and inheritance tax on wealth inequality in France. By switching to a proportional tax system for each type of tax , we find that income-tax progressivity is more effective than inheritance-tax progressivity in reducing wealth...

This paper extends the job creation–job destruction approach to the labor market to take into account a deterministic finite horizon. As hirings and separations depend on the time over which investment costs can be recouped, the life-cycle setting implies age-differentiated labor-market flows....

Nous proposons une maquette du marché du travail à tems complet sur le segment des moins qualifiés, tenant compte des interdépendances entre offre et demande de travail et dans laquelle les distributions de salaire et de productivité sont endogènes, résultat d’un jeu stratégique entre...
