STRUCTURAL PROPERTIES OF CORE–PERIPHERY COMMUNITIES

Advances in Complex Systems, 2023
Empirical studies have consistently demonstrated the presence of a core–periphery structure within social network communities. Nevertheless, a formal model and comprehensive analysis to fully understand the structural characteristics of these communities are still lacking.

SSRN Electronic Journal, 2014
AbstractCurrent account (CA) dispersion within European Union (EU) Member States has been increasing progressively since the 1990s. Interestingly, the persistent deficits in many peripheral countries have not been accompanied by a significant growth process able to stimulate a log run rebalancing as neoclassical theory predicts.

Core-Periphery Trading Networks

SSRN Electronic Journal, 2016
This paper provides a theory of endogenous network formation in over-the-counter markets based on trade competition and inventory risk balancing. A core-periphery network structure arises as an equilibrium outcome. A small number of agents emerge as core dealers to intermediate among a large number of peripheral agents.

Social Networks, 2000
A common but informal notion in social network analysis and other fields is the concept of a core/periphery structure. The intuitive conception entails a dense, cohesive core and a sparse, unconnected periphery. This paper seeks to formalize the intuitive notion of a core/periphery structure and suggests algorithms for detecting this structure, along ...

Power and Core-Periphery Networks

SSRN Electronic Journal, 2010
The heterogeneous connections model is a generalization of the homogeneous connections model of Jackson and Wolinsky (1996) in which the intrinsic value of each connection is set by a discrete, positive and symmetric function that depends solely on the types of the two end agents.

Biodiversity Along Core–Periphery Clines

Discussion regarding its definitions is dynamic, with shifts between the more traditional emphasis on community structure to emphasis on the higher ...
