Les pôles de compétitivité, basés sur le modèle des clusters, sont au coeur de la nouvelle politique industrielle française. Ils ont pour objet de favoriser un environnement propice à l'innovation à fort potentiel technologique, moteur de croissance économique. L'objectif de ce papier...

In this note, we extend the Goyal and Joshi's model of network of collaboration in oligopoly to multi-market situations. We examine the incentive of firms to form links and the architectures of the resulting equilibrium networks of this setting. We also present some results on efficient networks.

We report the results of an original experiment that was designed to test the strength and robustness of the attraction effect. Rather than the usual simple tests for this effect, we consider a conceptually simple consumer purchasing task where alternatives are however difficult to evaluate. For...

Social networks, be it on the internet or in real life, facilitate information flows. We model this by giving agents incentives to link with others and receive information through those links. We consider networks where agents have an incentive to confirm the information they receive from...

De manière générale, les incitations à innover dépendent d'un certain nombre de caractéristiques : coût de la R&D, nature de l'innovation, financement de la R&D... Dans ce cadre d'analyse, on peut montrer qu'il n'existe pas une relation simple entre un type d'innovation et son...

In a laboratory experiment we test the three regulations imposed on a common-pool resource game with heterougeneous users: an access fee and subsidy scheme, transferable quotas and non transferable quotas? We calibrate the game so that all regulations improve users' profits compared to...

In a within-subjects framework, we compare levels of transfer in the trust game and in the (triple) dictator game. We control preferences towards risk through the Holt and Laury test (2002) and social preferences with the ring test (Liebrand, 1984). We then provide evidence that social...

We run a market experiment where subjects take the role of firms and can choose not only their price but also whether to present comparable offers. Firms are faced with artificial demand whereby consumers make mistakes in assessing the net value of products on the market. Some of those consumers...
