Article considers problems of an assessment of efficiency of company’s activity on the basis of complex indicators of production results and resources. Tools of complex-valued economy – the new scientific direction having the theory of functions of complex variables as the basis – are used to modeling of economic dependences. The properties of exponential production function of complex variables with the real exponent are studied in the work. The function describes the interrelation between complex variable profit and costs of production and a complex labor and capital factor. Elasticity coefficients of complex-valued production function are investigated.
Practical application of the model for forecasting the efficiency of industrial production is considered on the example of " Erdenet Enterprise" (Mongolia). Construction of Kobb-Douglas production function for the analysis of activity of this enterprise was impossible. However the analysis of economic indicators of the enterprise by means of complex-valued production function yielded positive results. Calculation of elasticity coefficients for the function modeling activity of the enterprise, and also their interpretation are given in the article. The conclusion is made about the need of considering such problems as work organization by the company’s management for the purpose of increasing the production efficiency of the enterprise.
State Capitalism could be characterized by a triple role of the state: the state performs as a “programmer” to guide economic activity; it acts as a “protector” to safeguard national economic interests; and it also plays the role as a “producer” to create national wealth through its state-owned enterprises (SOEs). However, the influences of State Capitalism in a country are not only limited to the domestic sphere. They often extend internationally, either through the globalization of SOEs, or through Sovereign Fund investments, or by means of other influences. Many recent acquisition projects by SOEs, often in strategic sectors, highlight the importance of understanding this new geopolitical investment which has created special relations between State Capitalism and the free market. They also raise the question of the need for updating national economic security concerns in the context of globalization. As the value of Sovereign Funds reaches several trillion dollars, the controversy surrounding these Funds is evolving. For many, these Funds do not necessarily always look for maximizing business performance, but are sometimes also accompanied by political and strategic ambitions of the respective states from where they originate. The phenomenon of State Capitalism has gained prominence in recent years especially in several emerging markets. It appeared, firstly, because of multiple government interventions in the economy,and secondly, emphasis given to the globalization of their SOEs / economic organizations in international markets (China, Russia, Brazil, Malaysia, Saudi Arabia, India, Korea, etc.). In January 2012, The Economist published another special article on State Capitalism and wondered if the new balance of power that is being built-up with the emergence of market oriented SOEs will pose a challenge to the liberal capitalist model. The objectives of this conference are manifold: to examine the characteristics of State Capitalism in the world economy, especially in emerging countries, to assess its real impact on economic development, to identify its scope to other developing countries, and also to explore the major challenges that it poses to the liberal capitalist model in the world of free-markets.
The subject matter of the article lies between public law and economics. The article contains sources of legal regulation in state corporations, ways of their forming, jurisdiction, priorities and results of its activities achieved in western democracies. The author stresses the dependence of effectiveness of this public law institute on checks and balances as well as individual responsibility, responsibility for doings and refraining from doing by authorities, reputation of officials.
Given the specificity of Russia can be said that the development potential microgrid very high, but the level of its use will depend on the model for the energy sector development. In this article the basic model for this development, given their estimate with the benefits and risks. The results of the pilot study, the authors of the effectiveness of model projects microgrid in Far Eastern Federal District (FEFD).
The article discusses the legal content of the principle of efficiency of public expenses in Russia as one of the underpinnings of the financial activities of state and municipal entities in Russia. The author analyzes the current legislation, identifies the characteristics of the principle of efficiency of public expenditure in certain legal norms. The author finds that the principle of effectiveness of public expenses is incompletely regulated in Russia. The article concludes that the principle of effectiveness of public expenses is the institutional principle of financial law. The principle of effectiveness of public expenses covers all financial activity of state and municipal entities associated with the expenditure of public funds.
The paper consists of three main sections. The first is devoted to a discussion of the "state capitalism" concept and the reasons for the growing interest to this phenomenon. It is proposed here to consider the state capitalism not only in terms of the state ownership in major national industrial enterprises and banks, but also taking into account the efficiency of SOEs. In the second section, the new data on the state involvement in the Russian economy are represented, including the shares of the state in the authorized capital of the largest industrial enterprises and banks. Their economic indicators are compared. Contrary to some assumptions P / E values for national champions are lagging behind the average for emerging markets. The third section examines the hypothesis that one of the major challenges faced by the state capitalism is the development of investment incentives for SOEs and their performance. It is shown that the interests of the state as an owner of business enterprises are often in conflict with the interests of the state as a social institution. A number of examples are demonstrated. In order to solve this problem the state should reduce its stakes in SOEs except for those that are of strategic importance. The output of the analysis is that the state capitalism as a social phenomenon has no a long-term perspective. Most of so called “state capitalist” countries will take in future the path of traditional mixed market economy.
The general region socio-economical developement estimation approach is based on the agregation of diffeerent indices into one number. This approach leads to the loss of information, because highly economically developed regions are mixed with the poorly developed regions which live only due to subsidies. The new complex-valued index is proposed in the article. The usage of the index allows to evaluate the regions' developement from two separated sides: the social developement and economical developement. The simple way of such a complex-valued indices is proposed in the article.
The article considers the processes of progress in production and service sectors and answers the question how and thanks to what service sector of Russian economy left the productive one behind (concerning contribution in GDP of our country). The rates of development of service sector turned out to be so high firstly - as a reason of peculiarities of new Russian economy, which historically was built on the market principles and was developing in conditions of investment resources deficit, secondly - as a reason of system differences between «physical» goods and services as an object of sale. Nowadays Russia faces an unusual symbiosis: effective service companies, operating in hard competitive sphere with average profitability and non-affective from the point of management industrial companies, which thanks to monopolistic pricing have great profitability, providing profits of Russian budget and determining a macroeconomic situation.
The monograph examines solutions to complex problems a comprehensive assessment of the effectiveness of health interventions on the example of a multi-karidioreabilitatsii. One of the main tools for solving this problem, used in the book are the methods of mathematical modeling, basically - methods of mathematical statistics. An important distinguishing feature of this work is a careful approach to the formation of performance indicators. The criteria for the effectiveness of therapeutic and preventive measures proposed indicators of clinical, social and economic outcomes. This research study was sponsored by RHF, grant № 12-02-00436 «Cost-effectiveness modeling of health interventions on the example of the rehabilitation of patients after the provision of high-tech medical care in the profile "Cardiovascular Surgery".
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.
Event logs collected by modern information and technical systems usually contain enough data for automated process models discovery. A variety of algorithms was developed for process models discovery, conformance checking, log to model alignment, comparison of process models, etc., nevertheless a quick analysis of ad-hoc selected parts of a journal still have not get a full-fledged implementation. This paper describes an ROLAP-based method of multidimensional event logs storage for process mining. The result of the analysis of the journal is visualized as directed graph representing the union of all possible event sequences, ranked by their occurrence probability. Our implementation allows the analyst to discover process models for sublogs defined by ad-hoc selection of criteria and value of occurrence probability
Existing approaches suggest that IT strategy should be a reflection of business strategy. However, actually organisations do not often follow business strategy even if it is formally declared. In these conditions, IT strategy can be viewed not as a plan, but as an organisational shared view on the role of information systems. This approach generally reflects only a top-down perspective of IT strategy. So, it can be supplemented by a strategic behaviour pattern (i.e., more or less standard response to a changes that is formed as result of previous experience) to implement bottom-up approach. Two components that can help to establish effective reaction regarding new initiatives in IT are proposed here: model of IT-related decision making, and efficiency measurement metric to estimate maturity of business processes and appropriate IT. Usage of proposed tools is demonstrated in practical cases.
The paper studies a problem of optimal insurer’s choice of a risk-sharing policy in a dynamic risk model, so-called Cramer-Lundberg process, over infinite time interval. Additional constraints are imposed on residual risks of insureds: on mean value or with probability one. An optimal control problem of minimizing a functional of the form of variation coefficient is solved. We show that: in the first case the optimum is achieved at stop loss insurance policies, in the second case the optimal insurance is a combination of stop loss and deductible policies. It is proved that the obtained results can be easily applied to problems with other optimization criteria: maximization of long-run utility and minimization of probability of a deviation from mean trajectory.
