Marshallian districts are locales that accomodate a large number of small firms producing similar goods to be exported and benefit from the accumulation of know-how associated with workers residing there. We study the making of such districts by assuming that the cost function of a firm is a...

This note exhibits sufficient conditions concerning the skills of old workers ruling out overaccumulation stationnary equilibria in an OLG model with productive capital.

The aim of this paper is to set the foundation of an approach of the diffusion-adoption problem of an innovation or a technological standard, based on the building of influence matrixes. This means that agents are to be considered as participating in social networks that provide the support and...

We consider an economic system composed of interacting potential adopters of a technology. We build a model of interindividual influence effects in which part of the links can be negative, in a context of bounded rational choice. The article shows how the sole relationships topology on a network...

This paper analyses the evolution of trading relationships in a market in which trades take place bilaterally. Buyers reinforce their probability of visiting sellers as a function of the profitability of their past experience. Using the "mean field" approach it is shown that two distant types of...

I apply three noncooperative models of coalition formation to a Cournot olygopoly. In each model, each firm has to choose the coalition it wants to belong to. But each of those models is characterised by a different assumption that defines what happens to a coalition from which one or more...

In this work, a new axiomatization of the Shapley value is presented. An associated game is constructed which can also be interpreted as a perturbation of the original game. We define a sequence of games, when the term of order n, in this sequence, is the associated game of the term of order (n-1).
