Liquidity in Credit Networks: A Little Trust Goes a Long Way
Liquidity Credit Networks Little Trust Goes a Long Way
2010/10/21
Credit networks represent a way of modeling trust between entities in a network. Nodes in the network print their own currency and trust each other for a certain amount of each other's currency. This...

Traditionally many studies of knowledge in economics have focused on localized networks and intra- regional collaborations.However, t he rising frequency by which firms collaborate within the context...
Characteristics of Real Futures Trading Networks
Complex networks Futures trading networks Scale-frees caling Small-world effect
2010/4/28
Futures trading is the core of futures business, and is considered as a typical complex system. To investigate the complexity of futures trading, we employ the analytical method of complex networks. F...

Boolean delay equations on networks: An application to economic damage propagation
Boolean networks application economic damage propagation
2010/10/18
We introduce economic models based on Boolean Delay Equations: this formalism makes easier to take into account the complexity of the interactions between firms and is particularly appropriate for st...
Adaptive financial networks with static and dynamic thresholds
Adaptive financial networks static and dynamic thresholds
2010/10/18
Based on the daily data of American and Chinese stock markets, the dynamic behavior of a financial network with static and dynamic thresholds is investigated. Compared with the static threshold, the ...
Sequential optimizing investing strategy with neural networks
Sequential investing strategy with neural networks
2010/10/18
In this paper we propose an investing strategy based on neural network models combined with ideas from game-theoretic probability of Shafer and Vovk. Our proposed strategy uses parameter values of a ...
The Structure and Growth of Weighted Networks
weighted networks analysis proportionate growth preferential attachment international trade
2010/11/1
We develop a simple theoretical framework for the evolution of weighted networks that is consistent with a number of stylized features of real-world data. In our framework, the Barab´asi-Albert ...
Cooperation and Friendship Choice Heuristics in Dynamic Local Interaction Networks
Cooperation and Friendship Choice Dynamic Local Interaction Networks
2009/11/30
I built an agent-based model that simulates economic interaction in a social
network. In the model, agents dynamically break and create network links
based on whether their neighbors cooperate in ...

Crude Oil Future Price ANN Prediction Models
2010/11/1
This paper presents a model based on multilayer feedforward neural network to forecast crude oil spot price direction in the short-term, up to three days ahead. A great deal
of attention was paid on ...
Sign and amplitude representation of the forex networks
Sign amplitude representation forex networks
2010/11/2
We decompose the exchange rates returns of 41 currencies (incl. gold)into their sign and amplitude components. Then we group together all exchange rates with a common base currency, construct Minimal ...
Systemic Risk in a Unifying Framework for Cascading Processes on Networks
Systemic Risk Unifying Framework Networks
2010/11/1
We introduce a general framework for models of cascade and contagion processes on networks, to identify their commonalities and differences. In particular, models of social and financial cascades, as ...

A system for Operational Risk management based on the computational paradigm of Bayesian Networks is presented. The algorithm allows the construction of a Bayesian Network targeted for each bank using...
Backbone of complex networks of corporations: The flow of control
Backbone complex networks of corporations
2010/10/29
We present a methodology to extract the backbone of complex networks based on the
weight and direction of links, as well as on nontopological properties of nodes. We show how
the methodology can be ...
