In this note we introduce different levels of decay in the Goyal, Galeotti and Kamphorst (GGK) insider-outsider model of network formation. First, we deal with situations where the amount of decay is sufficiently low to avoid superfluous connections in strict Nash networks and we examine the...

In this article, we examine the role played by heterogeneity in the popular “connections model” of Jackson and Wolinsky (J Econ Theory 71(1):355–365, <CitationRef CitationID="CR5">1996</CitationRef>). We prove that when heterogeneity with respect to the values of resources, or the information decay parameter, depends on the identity...</citationref>

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...

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...
