Our paper seeks to gain insights into the effects of labor-market institutions on the dynamics of the labor market, during the diffusion process of new technologies. Because these institutions differ between Europe and the United States, we expect the dynamics of the labor market to also diverge...

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....

New-Keynesian macroeconomics usually provides recommendations for monetary policy in an economy where a subsidy eliminates the mark-up at the steady state : the natural output is then optimal. In this paper, we propose to study the ?uctuations around an inefficient natural output. We show that...

Endogenous cycles cannot emerge in one-sector monetary overlapping generations models when there is intertemporal substitutability, even if returns to scale are increasing. In this article, we show that the conclusions are different when there are two sectors. Considering a two-sector monetary...

This paper studies the optimal unemployment insurance for older workers in a repeated principal–agent model, where the search intensity of risk-averse workers (the agents) is not observed by the risk-neutral insurance agency (the principal). When unemployment benefits are the only available...

[eng] This paper develops a quantitative overlapping generations model with altruistic individuals that is useful for analyzing the long-run distributional implications of demographic changes and pension reform in France. We adopt an original mar- kovian representation by introducing constant...
