We find that the country has a high inter-industry wage inequality compared with the European standard. Nevertheless, the dispersion reduced over the 1980s and the early 1990s along a process of centralisation of the wage sett...

in this paper, optimum location of power system stabilizers in order to damp inter-area oscillations has been investigated by using modal series method. nonlinear effects grow in dynamical behaviors of heavily loaded stressed power systems significantly. hence linear based methods and techniques no longer present clear and exact response of the systems. in this article by defining new nonlinear...

We provide visualizations of the architecture of the economy that are informed by theory, empirically based, and meaningful at multiple levels of analysis. The systems-based view of industry architecture disaggregates the economy into demand-based vertical sectors in which firms collaborate and compete to collectively satisfy a set of similar demands. Within vertical sectors, inter-industry rel...
