Методология типизации траекторий посткризисной динамики российских предприятий обрабатывающей промышленности
By applying the hierarchical cluster analysis the most typical post-crisi trajectories of turnover dynamics for Russian manufacturing firms are revealed.It is shown that about 90% of cases belong to two types of dynamics (which we conventionally mark as "sustainable growth" and "stagnation"). The article suggests the possible directions of studying such stable cluster groups and the algorithm of selection of the most typical representatives of different clusters. The clustering approach to the aggregation of the micro-economic statistical data may be used for improving the state economic policy aimed at overcoming of the consequences of economic crises. At the enterprise level of analysis this methodological approach provides an opportunity to develop strategies that facilitate the resistance to negative external shocks.
Regression, cluster and component analysis of economic globalization of several developed economies is conducted with the purpose to find out the level of international trade globalization. 4 clusters on the basis of trade balance in goods, trade balance in services, FDI are found out.
This book provides a unique and timely analysis of the role of structural change in the economic development of Brazil, Russia, India, China, and South Africa (BRICS) with a consideration for the role of industry, and in particular manufacturing. The emergence of BRICS reflects an ongoing change in the international economic order. BRICS now account for very substantial part of global GDP, global manufactured value added and global manufactured exports. The book examines their economic experiences and structural change in BRICS over the past three decades, identifying both differences and commonalities, and deriving lessons for other industrializing countries. Section I contains comparative studies focusing on the commonalities and differences of the experiences of BRICS. Section II includes six country studies providing a more detailed analysis of the long-run experiences of each of the countries. Section III consists of a set of seven thematic studies focusing on specific topics such as global value chains, the role of transnational corporations in the food chain, the role of foreign versus domestic investment, the role of domestic versus foreign demand in economic growth the diffusion of environmental energy technology and the similarities, and the differences in industrial policies pursued in the five countries. The book contains a summary chapter that provides an integrated perspective of the various contributions from the point of view of poverty reduction and development. It asks, whether the patterns of structural change and industrial development that BRICS experienced, had an impact on poverty outcomes, and if so, what where the channels and the consequences?
We present a complex analysis of business models for large, medium and small Russian commercial banks from 2006 to 2009. The Russian banks are grouped based on homogeneity criteria of their financial and operational outcomes. The banks’ structure of assets and liabilities, profitability and liquidity ratio are taken into account. The results show how the banks are adjusted their business models before and after the financial turmoil taken place in 2008. In addition, the prevailing banking business models observed for the leading banks in Russia are defined. The banks often changing their business models are found and analyzed.
Data Correcting Algorithms in Combinatorial Optimization focuses on algorithmic applications of the well known polynomially solvable special cases of computationally intractable problems. The purpose of this text is to design practically efficient algorithms for solving wide classes of combinatorial optimization problems. Researches, students and engineers will benefit from new bounds and branching rules in development efficient branch-and-bound type computational algorithms. This book examines applications for solving the Traveling Salesman Problem and its variations, Maximum Weight Independent Set Problem, Different Classes of Allocation and Cluster Analysis as well as some classes of Scheduling Problems. Data Correcting Algorithms in Combinatorial Optimization introduces the data correcting approach to algorithms which provide an answer to the following questions: how to construct a bound to the original intractable problem and find which element of the corrected instance one should branch such that the total size of search tree will be minimized. The PC time needed for solving intractable problems will be adjusted with the requirements for solving real world problems.
The analysis of region differentiation of microentrepreneurship development and indexes of judicial statistics based on the current data of statistical recording are given in the article. The capabilities of cluster analysis for revelation of typological groups of the Russian region depending on the level of entrepreneurial activities and the results of law enforcement practice are represented.
This paper presents a pattern behavioral analysis of 100 largest Russian commercial banks by total assets during an eight- year period: from the first quarter of 1999 to the second quarter of 2007. Bank performance indicators are analyzed. Structural similarities in the development of the banks are examined. A cluster analysis is applied to determine banks with a similar structure of operations. This analysis allows to estimate how the structure of the Russian banking system has been changing over time. In particular, it allows to identify prevailing patterns in the behavior of Russian commercial banks and to analyze the stability of their position in a particular pattern.
This article provides the results of development of bankruptcy prediction static model and its testing on the sample of more than thousand companies of manufacturing industry. The main scenarios of bankruptcy are identified and it is shown that depending on the bankruptcy scenario possible insolvency can be predicted one or four years before.
How seriously does the degree of trust in basic social and political institutions for people from different countries depend on their individual characteristics? To answer this question, three types of models have been estimated using the data of the fifth wave of the World Value Survey: the first one based on the assumption about a generalized relationship for all countries, the second one taking into account heterogeneity of countries (using introduction of the country-level variables), the third type applying a preliminary subdivision of countries into five clusters. The obtained results have been used for suggestion of possible actions to increase public confidence in the basic institutions.
A model for organizing cargo transportation between two node stations connected by a railway line which contains a certain number of intermediate stations is considered. The movement of cargo is in one direction. Such a situation may occur, for example, if one of the node stations is located in a region which produce raw material for manufacturing industry located in another region, and there is another node station. The organization of freight traffic is performed by means of a number of technologies. These technologies determine the rules for taking on cargo at the initial node station, the rules of interaction between neighboring stations, as well as the rule of distribution of cargo to the final node stations. The process of cargo transportation is followed by the set rule of control. For such a model, one must determine possible modes of cargo transportation and describe their properties. This model is described by a finite-dimensional system of differential equations with nonlocal linear restrictions. The class of the solution satisfying nonlocal linear restrictions is extremely narrow. It results in the need for the “correct” extension of solutions of a system of differential equations to a class of quasi-solutions having the distinctive feature of gaps in a countable number of points. It was possible numerically using the Runge–Kutta method of the fourth order to build these quasi-solutions and determine their rate of growth. Let us note that in the technical plan the main complexity consisted in obtaining quasi-solutions satisfying the nonlocal linear restrictions. Furthermore, we investigated the dependence of quasi-solutions and, in particular, sizes of gaps (jumps) of solutions on a number of parameters of the model characterizing a rule of control, technologies for transportation of cargo and intensity of giving of cargo on a node station.
