Multi-echelon distribution schemes are one of the most common strategies adopted by the transport companies in an aim of cost reduction, but their identification in scientific literature is not always easy due to a lack of unification. This paper presents the main concepts of two-echelon...

We present the leading hypotheses of a work in progress aiming at testing and comparing neural activities in the case of a cognitive illusion (the bat-and-ball illusion) and in the case of a typical instance of framing effects. We focus on contrasted answers linked to Stanovich's system 1 vs...

This paper introduces a partner heterogeneity assumption in the one-way flow model of Bala and Goyal (2000, [1]). Our goal consists in the characterization of strict Nash networks with regard to the set of resources obtained by players. We use the notion of condensation network which allows us...

Marie-José Avenier (CERAG, Grenoble) réagit sur les questions épistémologiques soulevées dans le précédent numéro en défendant le paradigme constructiviste. Pour elle, il s'agit bien d'un paradigme même si elle distingue différents types de constructivisme, fondé sur des hypothèses...

Afin de limiter les impacts du changement climatique sur la planète, les experts du Groupe Intergouvernemental d'experts sur l'Evolution du Climat (GIEC) préconisent une division par deux des émissions mondiales de gaz à effet de serre à l'horizon 2050. Cet objectif impose une division par...

Dans cet article, nous argumentons, à la suite d'autres auteurs et à partir d'une recherche qualitative récente, qu'il existe une spécificité des modes de transmission des savoirs dans les PME régulièrement sous-estimé par les enquêtes officielles. Nous mobilisons dans cet objectif la...

Les recherches qualitatives se veulent souvent exploratoires : elles entendent inventer des concepts, proposer de nouvelles notions et théories. Dans le même temps, pour interpréter les données, elles manient des concepts existants. Mais bien souvent, les notions utilisées ou proposées...

We provide existence results in a game with local spillovers where the payoff function satisfies both convexity and the strategic substitutes property. We show that there always exists a stable pairwise network in this game, and provide a condition which ensures the existence of pairwise...

In this paper we examine the role played by heterogeneity in the popular “connections model” of Jackson andWolinsky (1996). We prove that under heterogeneity in values or decay involving only two degrees of freedom, all networks can supported as Nash. Moreover, we show that Nash networks may...

In this paper, we pursue the work of H. Haller and al. (2005, [10]) and examine the existence of equilibrium networks, called Nash networks, in the noncooperative two-way flow model (Bala and Goyal, 2000, [1]) with partner heterogeneous agents. We show through an example that Nash networks do...
