In two-player games with negative (positive) spillovers it is well-known that symmetric agents both overact (underact) at the Nash equilibria. We show that for heterogeneous agents this rule of thumb has to be amended if the game features strategic substitutability.

Luenberger [8] introduced the so-called benefit function that converts preferences into a numerical function that has some cardinal meaning. This measure has a number of remarkable properties and is a powerful tool in analyzing welfare issues ([10], [12], [13], [14]). This paper studies the...

After a long period of building, the microelectronics cluster in the Marseilles Metropolitan Area appears to have reached a critical size and investment dynamics capable to ensure its durability. In this paper we aim to enlighten such an assumption by analysing the nature of the process that led...

During the recent years, clusters have been at the heart of a vast literature supposed to bring new arguments and perspectives to local development preoccupations. Two complementary factors are stressing for firms and territories the importance of governing the interactions of industrial actors:...

[fre] Nous déterminons les enjeux économiques posés par tout exercice de calcul économique sur un projet d’infrastructures publiques et montrons les difficultés d’estimation des coûts et des bénéfices. Nous nous penchons aussi sur l’influence du niveau décisionnel (centralisé,...

Les tissus productifs de la région Provence Alpes Côte d'Azur ne sont pas tous semblablement engagés dans le mouvement de mondialisation mais aucun n'échappe aux effets accélérés de la phase actuelle d'internationalisation des échanges et de trans nationalisation des organisations...

La communication s'intéresse au renouvellement du tissu productif dans quatre sites d'une région du sud de la France, historiquement structurés par une activité productive. Dans chacun d'eux, la présence de ressources en connaissances et savoir-faire (situées ici dans les professionalités...
