Other types of socio-economic proximities characterize clusters, and our purpose is to show that, among the several … ways to analyze the complex links between proximities and clusters, the theoretical outlook on the role played by mimetic … and have a strong influence of the “evolutionary stability” of clusters. All these theoretical considerations are …

In a general model of trading networks with bilateral contracts, we propose a suitably adapted chain stability concept … that plays the same role as pairwise stability in two-sided settings. We show that chain stability is equivalent to … stability if all agents' preferences are jointly fully substitutable and satisfy the Laws of Aggregate Supply and Demand. In the …
