Bargaining structures, rent-seeking effect and endogenous growth.

Market power of workers on wages is bound to affect economic performances. This paper focuses on this issue and analyse the influence of bargaining structures on growth and labor market functioning. To achieve this, we construct an endogenous growth model where growth appears as the result of a learning-by-doing process whereas imperfect information in the labor market implies matching frictions in the hiring process. If investment occurs before wage bargaining, the growth process can be durably altered. In this case, a higher bargaining power of worker does not give a clear-cut effect on growth.Bargaining structures; Equilibrium Unemployment; Endogenous growth; Learning-by-doing.

The scarring effect of unemployment in ten European countries : an analysis based on the ECHP.

This paper investigates the effect of unemployment on earnings for ten European countries. Using an harmonised database (ECHP), we estimate the impact of declared unemployment on individuals while taking account of attrition and unobserved individual heterogeneity. We find that the unemployment effect differs by country and gender. The wage penalty is greater for men than for women. It is also higher in the more flexible economies. We suggest that labour market institutions such as unemployment benefits and wage-setting institutions may be avenues of investigation to explain these differences.Unemployment, Unobserved heterogeneity, post unemployment earnings.

Syndicalisation et croissance économique : y a-t-il une exception française ?

Cet article étudie les liens entre le taux de syndicalisation et la croissance économique dans plusieurs pays européens afin de répondre à l’interrogation suivante : le taux de syndicalisation influence-t-il la croissance économique ou la relation est-elle inverse ? Dans certains pays, nous n’observons aucun lien entre ces deux variables, mais dans d’autres (Suède, Allemagne) la croissance du PIB a une influence sur le taux de syndicalisation. La France fait ici figure d’exception : c’est le seul pays dans lequel le taux de syndicalisation influence la croissance économique, et ce, de manière positive.causalité, croissance économique, syndicalisation.

Are The State and The Family Unit Substitutable in The Financial Support of The Unemployed in Europe? A Comparison Based on The European Panel

The financial support of the unemployed falls to both the State and the family. The European panel data for the period 1995-2000 shows a difference between the countries of Northern Europe, where the State plays a preponderant role, and those of Southern Europe, where the contribution from the family compensates for a less generous State intervention. In the majority of the EU-10, State unemployment benefits appear to be greater when the financial support from the family is small, and are quite meagre when the family contribution is considerable. The family contribution does not fully compensate the disparities of State support observed between the countries: the standards of living of the unemployed remain highly contrasted and continue to reflect the disparities between the unemployment benefits systems.Unemployment Compensation, Well-Being, Family Structure

Opérations topologiques pour la géomorphologie

National audienceLes paysages naturels résultent d'une succession d'événements géomorphologiques qu'il convient de simuler pour produires des résultats plausibles. En particulier, les changements topologiques doivent être pris en compte durant la formation de géométries complexes comme les arches, les ponts ou les tunnels naturels. Nous présentons une nouvelle approche pour simuler les évolutions géomorphologiques d'un terrain en 3D conçu comme un ensemble de volumes définis dans un modèle topologique, et décrivons un ensemble d'opérations atomiques afin de gérer les événements topologiques de manière robuste. Ces opérations somt combinées pour produire des scénarios d'évolutions plus complexes dans un modeleur basé sur les cartes généralisées, permettant de réduire le coût mémoire par rapport aux méthodes utilisant des voxels par exemple

Preoperative Embolization of Hypervascular Castleman's Disease of the Mediastinum

We report the case of a 31-year-old woman with mediastinal Castleman's disease of the hyaline vascular type. This large tumor was safely resected after arterial embolization. We describe the steps of this interventional procedure and discuss related necessary precaution

Image-guided multipolar radiofrequency ablation of liver tumours: initial clinical results

The local effectiveness and clinical usefulness of multipolar radiofrequency (RF) ablation of liver tumours was evaluated. Sixty-eight image-guided RF sessions were performed using a multipolar device with bipolar electrodes in 53 patients. There were 45 hepatocellular carcinomas (HCC) and 42 metastases with a diameter ≤3cm (n = 55), 3.1-5cm (n = 29) and >5cm (n = 3); 26 nodules were within 5mm from large vessels. Local effectiveness and complications were evaluated after RF procedures. Mean follow-up was 17 ± 10months. Recurrence and survival rates were analysed by the Kaplan-Meier method. The primary and secondary technical effectiveness rate was 82% and 95%, respectively. The major and minor complication rate was 2.9%, respectively. The local tumour progression at 1- and 2-years was 5% and 9% for HCC nodules and 17% and 31% for metastases, respectively; four of 26 nodules (15%) close to vessels showed local progression. The survival at 1year and 2years was 97% and 90% for HCC and 84% and 68% for metastases, respectively. Multipolar RF technique creates ablation zones of adequate size and tailored shape and is effective to treat most liver tumours, including those close to major hepatic vessel
