Forecasting of electricity prices with neural networks
Electricity prices Energy prices forecasting Energy management Economics
2014/11/27
During recent years, the electricity energy market deregulation has led to a new free competition situation in Europe and other countries worldwide. Generators, distributors and qualified clients have...
Yard-Sale exchange on networks: Wealth sharing and wealth appropriation
Yard-Sale exchange networks Wealth sharing wealth appropriation
2012/9/14
Yard-Sale (YS) is a stochastic multiplicative wealth-exchange model with two phases: a stable one where wealth is shared, and an unstable one where wealth condenses onto one agent. YS is here studied ...
Global Stability of Financial Networks Against Contagion: Measure, Evaluation and Implications
financial networks stability financial contagion network models.
2012/9/14
Involvements of major financial institutions in the recent financial crisis have generated renewed interests in fragilities of global financial networks among economists and regulatory authorities. In...
Kinship and Financial Networks, Formal Financial Access, and Risk Reduction
Kinship Financial Networks
2014/9/10
Kinship networks are beneficial for smoothing consumption and investment, but the channels are not well understood. We study the financing devices used for consumption and investment by Thai household...
Singularity strength based characterization of financial networks
characterization of financial networks Statistical Finance Data Analysis Statistics and Probability
2012/6/4
Financial markets are well known examples of multi-fractal complex systems that have garnered much interest in their characterization through complex network theory. The recent studies have used corre...
Credit Default Swaps Drawup Networks: Too Tied To Be Stable?
Credit Default Swaps Drawup Networks Risk Management
2012/6/2
We analyse time series of CDS spreads for a set of major US and European institutions on a pe- riod overlapping the recent financial crisis. We extend the existing methodology of {\epsilon}-drawdowns ...
Networks as the Pipes and Prisms of the Market
capital markets egocentric uncertainty market status
2011/9/18
This article draws an analytical distinction between two types of market uncertainty: egocentric, which refers to a focal actor's uncertainty regarding the best way to convert a set of inputs to an ou...
U.S. Commuting Networks and Economic Growth: Measurement and Implications for Spatial
economic growth entropy measures regional governance economic activity
2011/9/11
Labor market areas (LMAs) have long been a staple of regional and urban analysis. As commuting patterns have expanded over time, these areas have become larger and more complex, and the dichotomous de...
Exploring complex networks via topological embedding on surfaces
Complex Networks Maximal Embedded Graphs Triangulations Topological Froths Surface genus Hyperbolic networks
2011/7/20
We demonstrate that graphs embedded on surfaces are a powerful and practical tool to generate, characterize and simulate networks with a broad range of properties. Remarkably, the study of topological...
The Emergence of Leadership in Social Networks
Minority Game Social Networks Emergent Power Laws
2011/7/4
We study a networked version of the minority game in which agents can
choose to follow the choices made by a neighbouring agent in a social network.
We show that for a wide variety of networks a lea...
Economic classification and regression problems and neural networks
multilayer neural networks classification bankruptcy prediction time series prediction neural network training error functions
2014/2/27
Artificial neural networks provide powerful models for solving many economic classifications, as well as regression problems. For example, they were successfully used for the discrimination between he...
In this review we establish various connections between complex networks and symmetry. While special types of symmetries (e.g., automorphisms) are studied in detail within discrete mathematics for pa...
On the emergence of critical behavior in evolving financial networks
critical behavior evolving financial networks
2010/10/21
We introduce a simple model for addressing the controversy in the study of financial systems, sometimes taken as brownian-like processes and other as critical systems with fluctuations of arbitrary m...
Complex Networks and Symmetry II: Reciprocity and Evolution of World Trade
complexity networks symmetry breaking
2010/10/21
We exploit the symmetry concepts developed in the companion review of this article to introduce a stochastic version of link reversal symmetry, which leads to an improved understanding of the reciproc...
Characteristics of Real Futures Trading Networks
Complex networks Futures trading networks Scale-free scaling
2010/10/20
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...
