In this paper, we consider estimation of unknown parameters of the tapered Pareto distribution, which belongs to the class of semiheavy distributions, by a sample with excluded l_n largest and k_n smallest observations. We establish necessary and sufficient conditions in terms of proportions k_n/n and l_n/n for weak consistency and joint asymptotic normality of parameterizedmoment-type estimators for the shape and form parameters. Additionally, we extend the result on weak consistency of generalized Hill statistics (introduced in [V. Paulauskas and M. Vaiˇciulis, On the improvement of Hill and some others estimators, Lith. Math. J., 53(3):336–355, 2013]) to the case where the extreme value index is not positive. We demonstrate the performance of the proposed estimators on both simulated data from the tapered Pareto distribution and real data from finance.

This article addresses the issues of the marketing positioning of countries in the field of innovations. To date, the level of development and dynamism of the innovation sphere form the basis for the country's sustainable economic growth. The concept of "innovation" is closely related to the concepts of "novation", "invention", and "discovery", which are the products of creativity. The paper examines some of the basic marketing characteristics of such countries as Japan, China, South Korea, India, and Russia. The authors hypothesize and prove that if a country chooses to focus on education and high technologies in its development, it can ensure high development of the national information and communication technologies. They also selected and evaluated the indicators of innovative development for these countries. Based on the correlation-regression analysis, the initial hypothesis was confirmed.

Kazakhstan faced the problem of falling industrial production and decrease in efficiency of former managerial methods of territorial development. Transition to the new Smart Specialization approach provides better understanding of the specifics of the region and provides the highest return on investment in innovation. The authors produce rationale for the selection of regions of Kazakhstan to determine their smart specialization. There were determined the regions, in which it is advisable to develop the general purpose technologies, and the territories, where it is more profitable to focus on applied research and transmitting them into practice in relation to existing products and technological processes.

The purpose of the work is to determine the features of application of tax measures for stimulation of formation of information economy in modern Russia, to substantiate the perspectives of their expanded application, and to develop practical recommendations and to compile a tax mechanism of managing the process of formation of information economy in modern Russia. The authors use the systemic approach, methods of statistical analysis (analysis of statistical data), analysis of causal connections (logical analysis), and formalization (graphic presentation of authors' conclusions and recommendations). The authors conduct a complex evaluation of the level of development of information economy of modern Russia (as of 2018) based on the data of the National Research University "Higher School of Economics", IMD World Competitiveness Center, and the World Economic Forum and determine that for building competitive, highly-effective, and sustainable information economy in modern Russia, it is necessary to pay attention to the issues of development of E-government and the spheres of new information and communication technologies. The authors also perform a complex empirical analysis of the practice of taxation in modern Russia, which showed that tax measures that are used for managing the process of formation of information economy in modern Russia are contradictory and insufficient for achieving substantial progress in formation of information economy. As a result, it is determined that the current Russian tax mechanism of managing the process of formation of information economy in modern Russia could be characterized as restraining. Its drawbacks, related to insufficient attention to underdeveloped characteristics of information economy and contradiction, could be solved with the developed tax mechanism of managing the process of formation of information economy in modern Russia, which could be characterized as stimulating.

В работе рассматривается задача нахождения цен опционов европейского типа в условно-гауссовских моделях при наличии дополнительных составных пуассоновских скачков. Эти скачки моделируют внезапные падения цен акций как следствия политических или экономических причин. Обсуждаются гамма-дисперсионная и гауссовская обратно-гауссовская модели. Получены точные формулы для цен цифровых опционов в иностранной валюте. Цены опционов с более простыми платёжными функциями найдены как следствия основных результатов. Рассмотрены различные виды зависимостей между ценами рисковых активов.
