To investigate the actual phenomenon of transport on a complex network, we analysed empirical data for an inter-firm trading network, which consists of about one million Japanese firms, and the sales of these firms (a sale corresponds to the total in-flow into a node). First, we analysed the relationships between sales and sales of nearest neighbourhoods, from which we obtained a simple linear relationship between sales and the weighted sum of sales of nearest neighbourhoods (i.e. customers… 
Mean Field Approximation for Biased Diffusion on Japanese Inter-Firm Trading Network
TLDR
Using theoretical analysis, the mean-field solution of the model is obtained and it is found that, in the case of the Japanese firms, the scaling exponent of 1.3 can be determined from the power law of the average degree of the nearest neighbours of the network with an exponent of −0.7.

In this paper, we investigate the structure and evolution of customer-supplier networks in Japan using a unique dataset that contains information on customer and supplier linkages for more than
Many-to-one contagion of economic growth rate across trade credit network of firms
We propose a novel approach and an empirical procedure to test direct contagion of growth rate in a trade credit network of firms. Our hypotheses are that the use of trade credit contributes to
Corporate payments networks and credit risk rating
TLDR
This work investigates a large proprietary dataset of payments among 2.4M Italian firms, whose credit risk rating is known, and shows the existence of an homophily of risk, i.e. the tendency of firms with similar risk profile to be statistically more connected among themselves.
Modeling financial distress propagation on customer-supplier networks.
TLDR
A stylized model to understand the "domino effect" of distress in client-supplier networks using the combination of two stochastic terms: an additive noise, accounting by the capability of trading and paying obligations, and a multiplicative noise representing the variations of the market.
Missing Data as Part of the Social Behavior in Real-World Financial Complex Systems
TLDR
A framework for interpreting the missing observations in network data under the hypothesis that these observations are not missing at random is offered and demonstrates that strategic information withholding may be a valid general phenomenon in complex systems.
Simulation of Gross Domestic Product in International Trade Networks: Linear Gravity Transportation Model
In this study, we introduce a model to simulate gross domestic product (GDP) for international trade network data. By applying a linear gravity transportation model, we confirm that estimated values
Precise Calculation of a Bond Percolation Transition and Survival Rates of Nodes in a Complex Network
TLDR
Through precise numerical analysis, a new type of universal loopless percolation transition in randomly removed complex networks is revealed and survival probability is introduced as a new measure characterizing the robustness of each node.
Diffusion-localization transition caused by nonlinear transport on complex networks
TLDR
This research discovered a novel phase transition type of nonlinear transport as defined for directed complex networks, where the flux from one node to a neighboring node is given preferentially according to the scalar quantities at the neighbor nodes.

TLDR
This work reports on the first cross-country investigation of ownership networks, focusing on the stock markets of 48 countries around the world, and reveals that in the same countries, control is found to be highly concentrated at the global level, namely, lying in the hands of very few important shareholders.

TLDR
This paper considers the traffic of information packets that include driving, searching and queuing, and presents the results of extensive simulations on two classes of networks; a correlated cyclic scale-free network and an uncorrelated homogeneous weakly clustered network.

TLDR
Developments in this field are reviewed, including such concepts as the small-world effect, degree distributions, clustering, network correlations, random graph models, models of network growth and preferential attachment, and dynamical processes taking place on networks.

TLDR
The biased random-walk process in random uncorrelated networks with arbitrary degree distributions is studied to provide the basis for a theoretical treatment of transport-related problems in complex networks, including quantitative estimation of the critical value of the packet generation rate.
