Definition Of

The analysis of models of activity of banking structures in the conditions of perfect and imperfect competition is carried out. Production functions for financial companies are considered. Models of the bank's work as an institution of delegated monitoring are described. Models of dynamics of financial resources are analyzed, allow to describe processes of evolution of own capital of bank depending on dynamics of the involved resources and the policy of accumulation realized by it. The considered models and methods are based on the definition of a bank (a financial company) as some abstract object, which is characterized by input and output parameters, as well as the function that connects them. This approach to some extent allows adapting traditional models of research of industrial enterprises and organizations to the analysis of the activities of banking structures. Therefore, one of the main tasks is to optimize internal functioning. Under such conditions, it is especially important to consider the bank as a holistic complex dynamic system operating in an unstable transition economy and the use of economic and mathematical methods and models to study the processes taking place in the bank, assess its effectiveness, identify areas and ways to improve management banking activities. Based on the analysis of the main economic and mathematical models of behavior of financial companies in a monopolistic market, we can conclude that each model characterizes a certain aspect of financial market development by the situation. Production functions for a bank (financial firm) are built, where the problem of classification of these factors into input and output is significant. A wide class of economic and mathematical models is considered, in which the activity of financial and banking institutions is treated as financial intermediaries. The theory of delegated monitoring is generalized, which in the general case assumes that in conditions when there is an effect of the growth of income from scale, individual lenders prefer to delegate functions of control (monitoring) of the behavior of entrepreneurs in whose projects they have invested to special intermediary firms. banks. The analysis of the development of the banking sector of Ukraine showed that a further gradual slowdown in its pace is expected due to changes in conditions in global financial markets and market saturation.

Texture deals with the orientational aspects of the crystal lattice in polycrystalline aggregates. This comprises the classical orientation distribution function ODF as well as higher-order textural quantities. The quantitative treatment of these quantities requires a good deal of mathematical methods. This concerns particularly the representation of orientation data including all kinds of symmetries, the transformation of experimentally measured raw data into the required distribution functions, as well as mathematical models of texture formation by physical processes and of the texture-property relationship.When physical facts are idealized in terms of a mathematical description or by mathematical models then the physical limits, within which these are valid, must be known. Such physical limits are, for instance, definition of crystal orientation by the crystal lattice which leads to an unsharpness relationship between location and orientation resolution as well as a relationship between statistical relevance and angular resolving power. Other physical limits are given by the “fuzzyness” of sample symmetry. A central problem is pole figure inversion i.e. the inversion of the projection equation. This problem may have a “physical” solution even if it does not have a mathematical one. Finally, in the problem of rationalizing orientation distribution functions in terms of a low number of “components”, mathematical aspects may be quite different from physical ones.In all these problems it is thus necessary to keep the mathematical aspects apart from physical aspects.

The paper provides a definition of the economic mechanism for managing the communication business processes of industrial enterprises in the context of globalization as a set of a system of relations, authorities, forms and methods of organization and operation, which are regulated by legal and other norms of activity and provide effective interaction in internal and external environments. This allows to deepen the understanding of the essence in the context of globalization under the orientation towards communication (we mean interaction first of all). The composition of the comprehensive economic mechanism for managing the communication business processes of industrial enterprises is studied. This mechanism includes organizational, economic, legal, political, technical and technological, market, production, social, motivational, adaptive and communication submechanisms. This allows further formalization of the process of elemental improvement of the communication business processes of industrial enterprises. The components of mechanism are detailed. In particular, the economic submechanisms include the mechanisms of profits distribution, economic stimulus, financial, equity, investment and reinvestment in development and other mechanisms. The legal submechanisms include the mechanisms, which govern communication and professional legal relations. Organizational submechanisms include structural mechanisms, administrative and information mechanisms that ensure the development and modernization of communication activities at the enterprise, its information security. Political submechanisms include mechanisms of information policy, social and economic policy and foreign economic policy. Market submechanisms include the ones of market competition, demand and supply, etc. Social submechanisms include the ones of transparency of doing business, social responsibility, social and psychological impact, etc. Production submechanisms include the following ones: resource, implementation of new types of software and hardware and other. Technical and technological submechanisms include the ones of scientific and technological progress, technological updates. Motivational submechanisms include the mechanisms of material and non-material incentives of personnel. Adaptive submechanisms are the submechanisms of innovative development (including implementation of innovations in information field), managing the personnel potential, etc. Communication submechanisms include the ones of information-and-analytical activities (including research conducting); external communications (including the system of integrated communications tools, modern telecommunications and communications facilities); internal communications (including creating corporate culture). Key words: economic mechanism, submechanisms, management, communications, business processes, industrial enterprise.

Natural Hypothesis

AbstractResident physicians play a double role in hospital activity. They participate in medical practices and thus, on the one hand, they should be considered as an input. Also, they are medical staff in training and, on the other hand, must be considered as an output. The net effect on hospital activities should therefore be empirically determined. Additionally, when considering their role as active physicians, a natural hypothesis is that resident physicians are not more productive than senior ones. This is a property that standard logarithmic production functions (including Cobb–Douglas and Translog functional forms) cannot verify for the whole technology set. Our main contribution is the development of a Translog modification, which implies the definition of the input “doctors” as a weighted sum of senior and resident physicians, where the weights are estimated from the empirical application. This modification of the standard Translog is able, under suitable parameter restrictions, to verify our main hypothesis across the whole technology set while determining if the net effect of resident physicians in hospitals’ production should be associated to an output or to an input. We estimate the resulting output distance function frontier with a sample of Spanish hospitals. Our findings show that the overall contribution of resident physicians to hospitals’ production allows considering them as an input in most cases. In particular, their average productivity is around 37% of that corresponding to senior physicians.

The definition of effective improvement vectors is currently one of the most pressing challenges facing the industry representatives. The transition to the sixth technological mode effectively contributes to competition intensification in all markets of industrial products. This is largely due to the fact that existing process systems are at the peak of their effectiveness. Further development requires qualitative changes. However, the principal improvement is a long-term and high-risk process. For this reason the issue of creating effective models for assessment of the strategic lines of processes improvement becomes increasingly important for industrial enterprises. This article considers in details the vector of industrial enterprise processes improvement based on the integration of new materials. As a result, a model allowing to assess a perspectives level for integration of new materials in industrial enterprise processes is created.

Modelling And Forecasting

Introduction. Mathematical methods and models are an effective tool for studying complex economic systems at different levels of enterprise management. Economic mathematical modelling is actively developing not only as a scien-tific field but also as a means of substantiating management decisions in business, in the analysis and forecasting of socio-economic processes and phenomena. In the arsenal of economic and mathematical modelling now are using- modern computing methods and computer technology. Libraries of economic and mathematical models are an integral part of the architecture of decision support systems in specific areas of the economy. The rapid development of computer technology stimulates the emergence and formation of new theoretical volumes and applied areas of modelling.Purpose. Like any large and complex field of knowledge, mathematical modelling is evolving in different direc-tions, acquiring new flexible research methods. Therefore, based on new hardware, technology and software platforms it is necessary to create new information systems using economic and mathematical models in particular for forecasting of enterprise activities.Results. The article analyses the methods of modelling and forecasting the enterprise, considers the principles of software design. Using systems analysis, the design problem was analytically divided into parts. Also were investigated the connections and relationships between these parts, in particular, were implemented the problem tree and the goal tree. Implemented business process modelling performs based on created structural-logical diagrams, namely the IDEF0 dia-gram, which helps to visually display data and information that affect software development, a server part, input data and users. Using the results of research, the authors developed an automated information system for modelling and forecasting the activities of the enterprise, which uses models of Holt, Brown, exponential smoothing and Box-Jenkins for modelling. Part of the developed system is a designed software product that implements the objectives of the research. The obtained program results allow creating a clear forecast of the future activities of the enterprise.Conclusions. Based on the built graphs of modelling and forecasting of the Cisco Systems company financial activity with using of the developed automated system, we established that the Brown model is the best for providing educational sampling and a forecast of activity. The development of the automated system in the future involves the expansion of functionality, improvement and increasing of quality, as well as the creation of powerful analytics for more detailed forecasting.

A market economy requires flexibility in the operation of industrial enterprises, prompt adjustment of the nature and directions of production processes. That is why, in modern business conditions, the importance of not only ensuring the efficiency of economic entities, but also the formation of their potential and prospects for further development. It is proved that some modern industrial enterprises are characterized by the inability to really assess the production potential, incomplete use of available resources, the latest technologies, and modern methods of production management. Production potential has been identified as having several specific characteristics: integrity, interchangeability, interconnection, flexibility, or adaptability. It is noted that the potential concentrates three levels of connections and relationships at the same time: reflects the past, characterizes the present in terms of practical application, future-oriented. Six main methods used in the estimation of production potential are investigated and characterized: economic-statistical, method of production functions, method of cost estimation, index, indicator, and matrix methods. The principles that must be followed when diagnosing the production potential of the enterprise are determined: the completeness of the original data and the universality of the information base; reliability and availability of collected data; the possibility of using two types of assessment of production potential: resource-productive and rating; use of the concept of potential in a certain direction; use of basic and additional indicators; availability of certain evaluation criteria for the main and additional indicators. It is substantiated that the interpretation of the definition of “production potential” is ambiguous, as well as the methods of its evaluation. It is noted that without the study of production potential is not possible strategic development and planning of other activities of the enterprise and the process of managing the production potential of an industrial enterprise is aimed at efficient use of all its resources in the long run.

GATT Article III:4 aims at equal treatment in respect of competitive opportunities of imports and competing domestic products by preventing protectionism. A key question is whether regulations with heavier burdens on imported products than on domestic products and a valid regulatory purpose are consistent with Article III:4. Inquiry into regulatory purpose under Article III:4 would allow by-passing Article XX whose list of regulatory objectives is a closed one and which puts the burden of proof on the defending WTO member. In EC-Seal Products, the Appellate Body has rejected any role for the regulatory purpose inquiry under Article III:4. This article shows why a purely empirical definition of likeness and less favourable treatment as disparate impact cannot logically lead to a finding of a violation of Article III:4. It then argues that regulatory purpose continues to play a role under Article III:4 because of the centrality of the notion of competition. It proposes to frame that competition as perfect competition. It shows that the adoption of perfect competition as the evaluative benchmark for all of Article III:4 makes better legal sense than starting from imperfect competition for the likeness analysis and perfect competition for the less favourable treatment standard, as is proposed in the literature. It also shows that even in case where imperfect competition is used as the sole benchmark for both parts of Article III:4, an assessment of how regulation interacts with competition continues to play some role.
