Core-Periphery Structure in Networks
Intermediate-scale (or “meso-scale”) structures in networks have received considerable attention, as the algorithmic detection of such structures makes it possible to discover network features that are not apparent either at the local scale of nodes and edges or at the global scale of summary statistics. Numerous types of meso-scale structures can occur in networks, but investigations of such f...
متن کاملIdentification of core-periphery structure in networks
Many networks can be usefully decomposed into a dense core plus an outlying, loosely connected periphery. Here we propose an algorithm for performing such a decomposition on empirical network data using methods of statistical inference. Our method fits a generative model of core-periphery structure to observed data using a combination of an expectation-maximization algorithm for calculating the...
متن کاملStructure and dynamics of core/periphery networks
Recent studies uncovered important core/periphery network structures characterizing complex sets of cooperative and competitive interactions between network nodes, be they proteins, cells, species or humans. Better characterization of the structure, dynamics and function of core/periphery networks is the key step to our understanding of cellular functions, species adaptation, social and market ...
متن کاملCore and periphery in networks
We study a model of network formation where the bene ts from connections exhibit decreasing returns and decay with network distance. We show that the unique equilibrium network is a periphery-sponsored star, where one player, the center, maintains no links and earns a high payo¤, while all other players maintain a single link to the center and earn lower payo¤s. Both the star architecture and p...
متن کاملCore and Periphery in Endogenous Networks
Many economic and social networks share two common organizing features: (1) a coreperiphery structure; (2) positive correlation between network centrality and payo¤s. In this paper, we build a model of network formation where these features emerge endogenously. In our model, the unique equilibrium network architecture is a periphery-sponsored star. In this equilibrium, one player, the center, m...
