One of the most important properties of self-organized networks is their scale-free property. Prior research proved empirically and theoretically that scale-free networks emerge under the preferential attachment rule. However, a few empirical studies also show that empirical networks diverge...

Within this paper, we present the GridEcon Platform, a testbed for designing and evaluating economics-aware services in a commercial Cloud computing setting. The Platform is based on the idea that the exact working of such services is difficult to predict in the context of a market and,...

In this study, we develop a theoretical model based on social network theory to understand how the collaboration (co-authorship) network of scholars correlates to the research performance of scholars. For this analysis, we use social network analysis (SNA) measures (i.e., normalized closeness...

The article is devoted to the problems of the financial statements analysis, using the method of financial ratios. The choice of the main financial ratios is made having in mind peculiarities of the Russian Federation extractive industries. The recommended standard values of financial ratios are...

This paper presents a typology and classifies the literature on inventory models with multiple sourcing options. The categories for classification include the number of considered echelons, the source of uncertainty, the model structure, as well as the general research approach. By means of the...

The micro-economic foundation of a hospital's optimal resource allocation is discussed. The foundation of a quantitative method to evaluate a hospital's performance depends on the pure economic definition of efficiency. This study is important for scholars and practitioners in the field of...

It is shown that any completely preordered topological real algebra admits a continuous utility representation which is an algebra-homomorphism (i.e., it is linear and multiplicative). As an application of this result, we provide an algebraic characterization of the projective (dictatorial)...

In microeconomic analysis functions with diminishing returns to scale (DRS) have frequently been employed. Various properties of increasing quasiconcave aggregator functions with DRS are derived. Furthermore duality in the classical sense as well as of a new type is studied for such aggregator...

In a stylized Robinson Crusoe economy, we demonstrate the usefulness of homogeneity in initial conditions when solving and analyzing macroeconomic models. In a first step, we define state-like and control-like variables. In a second step, we introduce the value-function-like function. While the...

Taking into account the actual economic situation of the world with numerous financial crisis, the insurance companies should control their financial stability in order to avoid the insolvency or even bankruptcy state. Thus, the insurers should find the adequate methods of substantiating the...
