This study uses network theory to analyze the interactions of a representative sample of 13 European (EU) electricity spot prices during the period 2007–2012. We construct 7651 dynamic multivariate networks, where the nodes correspond to different EU countries and the links weight the...

To deal with the compatibility issue of full conditional distributions of a (discrete) random vector, a graphical representation is introduced where a vertex corresponds to a configuration of the random vector and an edge connects two vertices if and only if the ratio of the probabilities of the...

Many important markets, such as the labor market and the housing market, involve goods that are both indivisible and of budgetary significance. We introduce new graph theoretic objects ideally suited to analyzing such markets. We show that the minimum equilibrium price is characterized by a...

Based on the critical theory of communication, managing stakeholder relations is significant to achieve more democratic decisions that reconcile diverse interests of various stakeholders. However, power inequalities among stakeholders might inhibit to achieve finely balanced decisions. More...

An attempt is made to develop an integrated system model for the structure of water resources development and management system. The system consists of five subsystems such as watershed management, groundwater development, surface water management, field level development and climate change...

We introduce Stochastic Flow Diagrams (SFDs), a new mathematical approach to represent complex dynamic systems into a single weighted digraph. This topological representation provides a way to visualize what otherwise would be a morass of equations in differences. SFDs model the propagation and...
