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...

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