This work considers the problem of the optimal design of an hydrogen transmission network. This design problem includes the topology determination and the pipelines dimensioning problem. We define a local search method that simultaneously looks for the least cost topology of the network and for...

This paper deals with nonparametric estimation of conditional densities in mixture models. The proposed approach consists to perform a preliminary clustering algorithm to guess the mixture component of each observation. Conditional densities of the mixture model are then estimated using kernel...

A dynamic multi-sector model with net and excess mobility is developed to quantify the determinants of the canonical increasing wage-tenure profile. The model distinguishes between three factors: sector specific skill accumulation, sectoral-level shocks, and dynamic worker sector mismatch...

Les chiffres publiés par la Dares le 27 janvier 2014 confirment que 2013 ne s’est pas terminée avec l’inversion espérée de la courbe de chômage. Au contraire, les indicateurs étudiés ne s’améliorent pas. Le chômage est toujours en hausse et il affecte tous les groupes d’âge et...

While most of the literature on employment protection has focused on government-mandated severance pay, it has recently been documented that a substantial share of severance payments derives from private contracts or collective agreements. This paper studies the determination of these payments....

We simulate and estimate a new Keynesian search and matching model with sticky wages in which capital has to be financed with cash, at least partially. Our objective is to assess the ability of this framework to account for the persistence of output and inflation observed in the data. We find...

A matching model with labor/leisure choice and bargaining frictions is used to explain (i) differences in GDP per hour and GDP per capita, (ii) differences in employment, (iii) differences in the proportion of part-time work across countries. The model predicts that the higher the level of...
