Kovářík, Jaromír; Leij, Marco van der - 2011

Agents involved in the formation of a social or economic network typically face uncertainty about the benefits of creating a link. However, the interplay of such uncertainty and risk attitudes has been neglected in the network formation literature. We propose a dynamic network formation model...

A Spatial Approach to Network Generation for Three Properties: Degree Distribution, Clustering Coefficient and Degree Assortativity

Badham, Jennifer; Stocker, Rob - In: Journal of Artificial Societies and Social Simulation 13 (2010) 1, pp. 11-11

Social networks generally display a positively skewed degree distribution and higher values for clustering coefficient … distribution, clustering coefficient and assortativity. Both a general approach and specific implementation are presented. The …

Closed walks for community detection

Yang, Yang; Sun, Peng Gang; Hu, Xia; Li, Zhou Jun - In: Physica A: Statistical Mechanics and its Applications 397 (2014) C, pp. 129-143

In this paper, we propose a novel measure that integrates both the concept of closed walks and clustering coefficients to replace the edge betweenness in the well-known divisive hierarchical clustering algorithm, the Girvan and Newman method (GN). The edges with the lowest value are removed...

Detecting overlapping communities in networks using the maximal sub-graph and the clustering coefficient

Cui, Yaozu; Wang, Xingyuan; Li, Junqiu - In: Physica A: Statistical Mechanics and its Applications 405 (2014) C, pp. 85-91

. Two concepts named the maximal sub-graph and the clustering coefficient between two neighboring communities are introduced …. First, all the maximal sub-graphs are extracted from the original networks and then merge them by considering the clustering … coefficient of two neighboring maximal sub-graphs. And a new extended modularity is proposed to quantify this algorithm. The other …

Risk Aversion and Social Networks

Kovářík, Jaromír; van der Leij, Marco J. - In: Review of Network Economics 13 (2014) 2, pp. 121-155

Abstract This paper first investigates empirically the relationship between risk aversion and social network structure in a large group of undergraduate students. We find that risk aversion is strongly correlated to local network clustering, that is, the probability that one has a social tie to...
