ECONOMIC STATISTICS
The main objective of this study is to identify the characteristics of methods for regulating inflation processes in an open economy. In this regard, the article discusses in detail such issues as, features of inflationary processes in an open economy, the specifics of the impact of external factors on the level of inflation. On the example of the economy of the Republic of Tajikistan, the peculiarities of the influence of the dynamics of the exchange rate and foreign trade factor on the inflation rate are considered, the main factors influencing the dynamics of the national currency exchange rate are identified, the problem of regulating inflation tendencies in conditions of high import dependence is studied.
The theoretical basis for this study was the work of foreign and domestic scientists on the problems of inflation in an open economy, the impact of the exchange rate on inflationary processes, and the anti-inflationary monetary policy under conditions of high import dependence. Statistical data of the National Bank of the Republic of Tajikistan website - www.nbt.tj and the Statistical Agency under the President of the Republic of Tajikistan - www.stat.tj for 2000-2019 were used as an information database.
Results. The main factors of inflation in an open economy are identified. The mechanism of direct and indirect influence of foreign economic factors, in particular the exchange rate on inflationary processes, is investigated. The main factors of inflation and the mechanism of their influence on the example of the Republic of Tajikistan are investigated. The significant influence of external factors (imports, cash flow, exchange rate, dynamics of the Russian ruble) on inflationary processes and economic development of the Republic of Tajikistan has been revealed. The study shows that import is a factor that holds back inflationary trends in the country, external cash flows form domestic demand, influence the dynamics of the Somoni rate, and thereby affect the inflation rate. The significance of the Somoni exchange rate in regulating inflation processes has been determined. Significant influence of external factors on the formation of the Somoni exchange rate also was revealed. Based on the correlation and regression analysis, a close relationship is established between the dynamics of the Tajik Somoni and the Russian ruble. The article studies the peculiarity of the use of monetary policy in order to stimulate domestic production and export.
The results of the study show that in the conditions of the Republic of Tajikistan, foreign economic factors, in particular the exchange rate, largely determine inflationary trends. On this basis, an objective need arises to maintain the stability of the national currency in order to curb inflation and ensure the stability of economic development. The study showed that the dynamics of the exchange rate of Somoni largely determined by external than internal factors. For this reason, the presence of a significant effect of the exchange rate on inflationary trends in the long term may lead to undesirable consequences that are associated with the problem of regulating the exchange rate.
SOCIAL STATISTICS
Purpose of research. The relevance of the research topic is associated with the presence of a number of controversial issues arising in the statistical study of monetary incomes of the population of the country and regions. These issues include: comparability of monetary income in dynamics, assessment of differentiation of population by income and consumption, comprehensive assessment of regional differences in the income level. The aim of this work is to study the monetary income of the population of the Russian Federation as a universal characteristic of the living standard.
Materials and methods. The information base of the study was the official statistical materials of the Federal State Statistics Service, including the materials published by ROSSTAT in the “Statistical review” in early 2019. Along with traditional statistical methods, the study also used the method of assessing structural differences, the method of index analysis of the differentiation of the population by monetary income at both the Federal and regional levels. Structural shifts in consumer spending between groups with different income levels were identified.
Results. In Russia, from 2014 to 2017, the annual decline in real disposable income ranged from one to 3%, with an average annual growth rate of nominal income of 5%. In 2010–2018, more than 47% of income was concentrated in 20% of the population of the Russian Federation with the highest incomes. The 20% of the population with the lowest income accounted for less than 5.4% of the total. Inequality in the distribution of monetary income leads to the formation of consumer structures that differ in social groups with different levels of income. In the study, an integral coefficient of structural shifts of Gatev was used to estimate these differences. As a result of its calculation, significant structural differences between the groups of the population of Russia with the highest and lowest incomes were established.
A study was conducted on the level of monetary income of the population of 14 regions of the Volga Federal District in 2018. For all regions of the Federal District, three local indices were calculated on three indicators: average per capita monetary income of the population, the average monthly nominal accrued wages of employees of organizations and the share of the population with incomes below the subsistence minimum. Their arithmetic mean value representing the index of monetary incomes of the population was determined.
Conclusion. The results of the calculations allowed identifying three groups of entities in the district, which differ significantly in terms of cash income of the population. The problems of differentiation of monetary income in the Volga Federal District, identified in the study, are typical for many regions of Russia. In order to solve the problems, concerted actions of the regional government and the state, aimed at improving the living standard of the population of the country are necessary.
Purpose of the study. The purpose of this research is modeling of the current trends for changing the cost of the residential real estate. The price on the housing market is one of the most difficult indicators for the analysis, as it reflects trends in the commodity and financial markets, labor market, reacts to political, social and economic changes. On the housing market, it is possible to determine the level of income of the population and their ability to accumulate by the price if we consider the regional level, then it is possible to define degree of attractiveness of this or that region, etc. Development of the housing market promotes improvement of a demographic situation and development of social stability of the society.
Materials and methods. In the analysis of dynamics of changing the cost of the residential real estate, the methodological base is important. In this research, the methods of descriptive statistics for the description of the existing trends to change the average cost of housing and development of mortgage lending were presented and assessment of structure of price differentiation in regions is carried out. With the methods of identification and the analysis of the top trend, the adequate model, describing a trend functionally was constructed. For the evident representation of results of the research, tabular and graphic methods of visualization of data were used. For the purpose of the solution of objectives the package of the IBM SPSS Statistics application programs was used.
Results. Results of the research allowed to define the main trends of changing the cost of the residential real estate in the Russian Federation on primary and secondary markets and to analyze dynamics of granting mortgage loans. The reasons for significant regional price differentiation of housing are considered. Creation of model for changing the average cost of housing on primary and secondary markets is carried out and forecast estimates to change the price for 2019 are received.
Сonclusion. The conducted research showed that there is a steady trend of growth of cost for housing both on primary and secondary markets. It should be noted that in the nearest future the increase in rates of gain of the price in connection with the legislation change since July 2019 is possible, first, it would concern primary market, but in a consequence, it will be reflected also on the secondary market.
DEMOGRAPHIC STATISTICS
The aim of the research is to develop a methodology and assess the cross-border flows of HQs from Russia (permanent and temporary labor migrants), taking into account the peculiarities of the legislative conditions established by the host country (the criterion of the entry channel), on the example of the United States and South Korea.
Materials and methods. The focus is on the analysis of legal regimes of entry in terms of the identification of the category of HQs and the calculation of their number using a situational approach. The study used general theoretical methods and statistical methods: analysis of the dynamics of absolute and relative values. The information and statistical base of the study was made up of data from the Russian State Statistics, data from the statistical Agency – Eurostat, data from the US State Agency for Citizenship and Immigration, data from the Korean Statistics Agency KOSIS, data from the Headhunter survey.
Results:
– Three criteria have been developed on the basis of which the evaluation of the number of migrants-HQs from Russia can be made. These are the following: the criterion of the entry channel; the criterion of income and the educational criterion. The features of each criterion and the possibility of its application to estimate the number of HQs who left the country are specified.
– Identified the boundaries of the category of persons included in the HQs in accordance with the visa regimes of the USA and South Korea. This identification has distinctive features in each case and is determined by the level of development of the country for which the calculation of the number of HQs, who left the country, in this case – for Russia.
– The estimation of the dynamics of the number of HQs, who left Russia to the United States and South Korea, based on the criterion of the channel of entry, that is, in accordance with the legal conditions of entry of this category of persons in each country separately.
Conclusion. The article deals with the methodological problems of accounting for the migration of Highly Qualified Specialists from Russia, analyzes the volume and dynamics of their flows to individual countries: the United States and South Korea.
Estimates of the number of HQs who have emigrated from Russia to the United States and South Korea, have been calculated based on the identification of this category of persons in accordance with legislative modes of entry for different specialists, established in these countries, and taking into account the peculiarities of determining the HQs contingent for Russia. If the US law provides for a separate entry procedure for HQs, and the calculation of their number is not difficult, the legislation of South Korea does not have special types of visas for HQs, so their identification and calculation of the number is carried out by allocating a range of visas, which were used for the persons entering the country, representing the category of HQs for Russia. The peculiarity of the approach used in the work is also that the number of HQs, both in the US and in South Korea, includes persons who have entered for reasons of transfers within companies. Calculations similar to those presented in this paper should be made for a number of other countries – migration partners of Russia, which will make it possible to obtain an overall estimate of the number of HQs who left Russia and to assess the loss of human capital.
BUSINESS STATISTICS
The urgency of a comprehensive assessment of the current patterns of establishment and liquidation of legal entities in Russia is due to standing problems of the development of the national economy and increasing the volume of production of goods and rendering of various services, including based on accelerated growth of import substitution.
The purpose of the study: to assess the current demography of organizations in Russia, namely the levels of fertility and liquidation of organizations. The analytical assessment is based on two aspects of organizational demography: sectoral and regional. To provide a comparative analysis the assessment was carried out according to the data for 2017 and 2018.
Materials and methods. In the course of the study, the following indicators were considered for 19 types of economic activity and 82 regions of our country for 2017 and 2018 as the share of new organizations in the total number of functioning organizations, the share of liquidated organizations, as well as the existing ratio of the number of new and liquidated organizations. Official information of the Federal State Statistics Service on institutional transformations in the economy and demography of organizations was used as initial data. The research methodology is based on the consideration of newly created and liquidated organizations formed by industry and territorial characteristics. Modeling of values’ differentiation of specific weights of such organizations in the total number of the functioning organizations was carried out with the use of functions of density of normal distribution.
Results. According to the results of the study, the values of specific weights of new and liquidated organizations in their total number by industry and regions of the country were determined; it was shown that the number of liquidated organizations in most regions and types of economic activities for the period exceeded the number of newly created organizations; lists of regions and industries with high and low values of the considered indicators were established. The study tested and confirmed the following two hypotheses: the presence of a significant differentiation of the specific weights of created and liquidated organizations in the total number of organizations by types of economic activity; the presence of a significant differentiation of the specific weights of created and liquidated organizations in the total number of organizations by region.
Conclusion. The results are of theoretical importance in the conduct of research and training of students. Functions of density of normal distribution can be used at justification of plans and programs of development of economy of regions. The practical significance of the research results is associated with the possibility of their use in assessing the possibility of creating enterprises in specific industries and regions. The units of regional and municipal authorities monitoring the business climate can use the results of the work. The given methodological approach and obtained analytical estimates are of interest to financial credit and leasing companies in the justification of their policies, taking into account various activities and regional characteristics.
STATISTICAL AND MATHEMATICAL METHODS IN ECONOMICS
The aim of the research is the usage of an artificial neural network as a tool not only for forecasting, but also for operative diagnostics of a financial state through combining deterministic and stochastic factors in one model. This circumstance expands the possibilities of effective influence on the formation of an acceptable level of the company’s financial condition in various activities. The proposed universal model is presented in the article in relation to the company’s characteristics in the housing and utilities sector.
The article proposes a method for diagnosing the level of the housing and utility company’s financial condition based on the use of a factor neural model of the financial results of their activities.
Materials and methods. The neural network modeling methodology allows you to create models that have several advantages: learning ability (they adapt to various changes); universality (able to solve a wide range of data analysis and processing tasks); speed (process various data in parallel mode); ease of use (easy to operate after training); fault tolerance (resistant to local damage to the neural network structure and external noise).
One of the main tasks that neural networks successfully solve is the problem of classification – the assignment of the sample to one or several predefined classes. Most often, the input sample is determined by the input data vector. The components of this vector are the various characteristics of the sample. The classifier in the form of a neural network relates the object to one of the classes in accordance with the partitioning of the N-dimensional input space. The number of components of the vector determines the dimension of this space. In the context of this article, the input sample is the financial condition of the organization at a particular point in time. The input vector that characterizes the sample includes a set of direct and indirect factors of the financial results of a housing and utility company. The neurons of the output layer are a set of different classes. In the course of operation, the neural network assigns to each input vector a neuron in the output layer. The significance of the input data can be adjusted using connections between neurons and changing the neural network architecture. Neural networks can have a complex architecture when different parts of the neural network include different numbers of connections and different neurons.
The article develops the ideas laid down by its authors in [7, 8], where a neural network of direct propagation and a way of learning with a teacher have already been used. The model, described below, has been modified due to the authors’ desire to improve it, as well as dictated by the specifics of the housing and utility companies: a list of key indicators has been developed that affect not the financial result, but, consequently, the financial condition of companies in this sector of the Russian economy; the number of input factors characterizing the input sample was increased, each direct factor or group of direct factors was supplemented with an indirect factor; direct and indirect factors explaining the same processes are combined into clusters that influence the corresponding neuron; the number of neurons in the output layer has been expanded, the number of classes has been increased, the data are classified by means of the neural network in more detail; in the course of the program, it is possible to select the period to which the input data (month, quarter, half year, year) belong. The additions made a positive impact on the work of the neural network. The accuracy of attributing the input sample to a specific cluster and the sensitivity of the neural network has increased. The number of clusters has grown up to 50. Innovations have increased the usability of the program. New interface allowed to analyze data monthly. The programmatic way of interpreting the data has changed due to the fact that not all input data changes depending on the period.
Purpose of the study. Improving the speed and efficiency of decision-making on the development of sales of products by manufacturing companies based on the application of quantitative estimates of the potential of retail outlets, using automated methods of intellectual data analysis of Big Data.
In order to create new mechanisms for the intellectual management of enterprises (economic agents) in the concept of the digital economy, it is necessary to simulate the processes of their interaction in the organizational market environment from the perspective of a multi-agent approach. The approach describes cybernetic mechanisms of interaction of agents with the ability to adapt to the needs of the population based on the analysis of market situations in order to develop intelligent management systems for enterprises to increase their market potential and competitiveness. Today the paradigm of open complex systems is used to simulate and analyze the mechanisms and processes of interaction of agents in the market environment. The main modern functioning of enterprises are corporate information systems, telecommunication networks, Internet technologies, mobile communication systems, Big Data, technologies of intellectual analysis, forecasting and machine learning. In addition, information for modeling, research and analysis of the market and the behavior of agents can be collected from open sources on the Internet. In the field of mass sales, the result of the introduction of innovative technologies is the support of decision-making in the process of managing the sales of goods and services in order to synthesize effective business-strategies for the production and sale of goods, aimed at increasing the company’s profits.
From the point of view of the manufacturer, it is necessary to carry out strategic and tactical planning for the deployment and maintenance of the sales network through retail outlets that implement or have the potential to realize the company’s products. In the overwhelming majority of cases, experts make the collection and analysis of objective data on outlets, and the models for building quantitative estimates of the potential of outlets are used only the internal data on the sale of goods or partners.
Materials and methods. The solution is based on the analog method of assessing the attractiveness of the outlet, used in marketing. Data mining techniques (various clustering methods) and the method of mathematical statistics - variance analysis are also used to solve this problem.
Modern methods of processing large volumes of data and their intellectual analysis allow us to offer new methods for quantifying potential based on the analysis of the whole diversity of data stored in the open information sources.
Results. A multi-stage method of quantitative assessment of the potential of retail outlets in ruble equivalent was proposed. A method has been developed for dividing retail outlets into strata based on features describing the position of the retail outlets, competitive environment, transport accessibility, and a typical consumer. A modification of the K-means clustering method is proposed.
Conclusion. The paper proposes an approach to solving the task of promoting a wide range of products by the manufacturer through existing distribution networks. A method for quantitative assessment of the potential of outlets is proposed. The proposed method is based on the analog method of comparing outlets and uses the methods of clustering outlets across a wide range of indicators. The results of approbation of the approach on the data for 33 regions of the Russian Federation are given. The results of the work are planned to be used in the future to solve the problem of building a matrix of consumer preferences for outlets.
