We study imperfect competition between insurers in a multiple-risk environment. In the absence of asymmetric information, equilibria are efficient, and we determine the degrees of specialization under which the specialized insurers are able or unable to capture the surplus. We show in contrast...

In a differential information economy with quasi–linear utilities, monetary transfers facilitate the fulfillment of incentive compatibility constraints : the associated ex ante core is generically nonempty. However, we exhibit a well–behaved exchange economy in which this core is empty, even...

Notre étude a pour objectif de mesurer les effets spatiaux des externalités de connaissances sur la production de brevets des firmes, au niveau des villes. Nous utilisons une méthode originale basée sur le maximum d'entropie généralisé. Cette méthode permet de tester l'auto-correlation...

This paper explores the relationship between innovation and vocational training. We consider a linear feedback model to explain the dynamics of count data processes relative to patenting activities, R&D and training expenditures. Estimations are made on a panel data set relative to French...

This article investigates the effects of human capital and technological capital on innovation. While the role of technological capital as measured by research and development (R&D) expenditure has been intensively investigated, few studies have been made on the effect of employee training on...

Human capital is considered as one of the main inputs in economic growth. Human capital can generate endogenous growth thanks to a continuous process of knowledge and externalities accumulation (Aghion and Howitt, 1998). In that context, this paper explores the relationship between innovation...

Cet article porte sur les transformations en cours du corporate governance au Japon, domaine d'observation privilégié de la crise nippone au cours de la décennie quatre-vingt-dix. Ce travail s'inscrit dans un courant plus large de travaux cherchant à analyser la transition d'un système de...
