Null Models of Economic Networks: The Case of the World Trade Web
Giorgio Fagiolo, Tiziano Squartini, Diego Garlaschelli
In all empirical-network studies, the observed properties of economic networks are informative only if compared with a well-defined null model that can quantitatively predict the b…
Reconciling long-term cultural diversity and short-term collective social behavior
Luca Valori, Francesco Picciolo, Agnes Allansdottir +1
An outstanding open problem is whether collective social phenomena occurring over short timescales can systematically reduce cultural heterogeneity in the long run, and whether off…
Randomizing world trade. II. A weighted network analysis
Tiziano Squartini, Giorgio Fagiolo, Diego Garlaschelli
Based on the misleading expectation that weighted network properties always offer a more complete description than purely topological ones, current economic models of the Internati…
Randomizing world trade. I. A binary network analysis
Tiziano Squartini, Giorgio Fagiolo, Diego Garlaschelli
The international trade network (ITN) has received renewed multidisciplinary interest due to recent advances in network theory. However, it is still unclear whether a network appro…
Analytical maximum-likelihood method to detect patterns in real networks
Tiziano Squartini, Diego Garlaschelli
In order to detect patterns in real networks, randomized graph ensembles that preserve only part of the topology of an observed network are systematically used as fundamental null…
Networks with arbitrary edge multiplicities
Vinko Zlatic, Diego Garlaschelli, Guido Caldarelli
One of the main characteristics of real-world networks is their large clustering. Clustering is one aspect of a more general but much less studied structural organization of networ…
