In this paper, we investigate the mesoscale structure of the World Trade Network. In this framework, a specific role is assumed by short- and long-range interactions, and hence by any suitably defined network-based distance between countries. Therefore, we identify clusters through a new procedure that exploits Estrada communicability distance and the vibrational communicability distance, which turn out to be particularly suitable for catching the inner structure of the economic network.

The effect of the pandemic on complex socio-economic systems: community detection induced by communicability (preprint)/ en
This paper proposes a new methodological approach based on the Estrada communicability for identifying communities on a multiplex network, based on a two-step optimization, and shows that the community detection on thismultiplex network has greater information power than classical methods for single-layer networks.
The world trade network: country centrality and the COVID-19 pandemic
The results show that the number of infections and fatalities are larger in countries with a higher centrality in the global trade network, and the effect of different measures of centrality is compared.
Multi-Attribute Community Detection in International Trade Network
A new weighted network is constructed from the original one, in which weights are determined taking into account all the topological indicators in a multi-criteria approach, to solve the resulting Clique Partitioning Problem and find homogeneous group of nations.
Evolving community structure in the international pesticide trade networks
The statistical properties including community structure of the international trade net- works of all commodities as a whole have been studied extensively. However, the international trade networks
Environmentally extended input-output analysis in complex networks: a multilayer approach
A methodology suitable for a comprehensive analysis of the global embodied energy flow trough a complex network approach is proposed, by adapting to the existing literature an extension of the Kleinberg algorithm, called Multi-Dimensional HITS (MD-HITS).
Introduction to the special issue on the 24th annual Workshop on Economic science with Heterogeneous Interacting Agents, London, 2019 (WEHIA 2019)
Economics is traditionally divided into microeconomics, which studies the behavior of individual agents (such as a firm), and macroeconomics, which studies the behavior of an economy at the aggregate
Communities in world input-output network: Robustness and rankings
We introduce a method for assessing the robustness of community detection and apply it to a world input-output network (WION) to obtain economically plausible results. This method enabled us to rank
Conclusion and Policy Implications
After about a quarter century of countries having pursued deep regional integration through negotiating on deep regional trade agreements (RTAs), we observed a number of historical events that

An index Q is defined based on communicability and shortest path distances, which allows reinterpreting the "small-world" phenomenon as the region of minimum Q in the Watts-Strogatz model and displays unique features for the analysis of complex networks in different scenarios.

Four approaches are used to analyze communities in the WTW between 1962 and 2008, based, respectively, on modularity optimization, cluster analysis, stability functions, and persistence probabilities, finding no evidence of significant partitions.
The evolution of the world trade web: a weighted-network analysis
This paper employs a weighted network approach to study the empirical properties of the web of trade relationships among world countries, and its evolution over time. We show that most countries are

Patterns of dominant flows in the world trade web
The large-scale organization of the world economies is exhibiting increasing levels of local heterogeneity and global interdependency. Understanding the relation between local and global features
Communicability in complex networks.
A new measure of the communicability of a complex network is proposed, which is a broad generalization of the concept of the shortest path and able to distinguish finer structures of networks, such as communities into which a network is divided.
The World Trade Network
This paper uses the tools of network analysis and graph theory to graphically and analytically represent the characteristics of world trade. The structure of the World Trade Network is compared over

This network displays the typical properties of complex networks, namely, scale-free degree distribution, the small-world property, a high clustering coefficient, and, in addition, degree-degree correlation between different vertices.
