В статье рассмотрена деятельность ведущих кредитных рейтинговых агентств (Fitch Ratings, Moody's Investors Service и Standard & Poor's) в контексте снижения информационной ценности кредитных рейтингов, которые они присваивают, и сохранения доминирующих позиций на рынке финансового рейтингования. Целью исследования является рассмотрение деятельности кредитных рейтинговых агентств в измерении социального конструкционизма в процессе осуществления государственной финансовой политики, объясняя сопротивление регулятивной модели их деятельности многочисленным вызовам и переменам. Подход новой институциональной социологии в управлении мы сделали чувствительным к проблематике институциональных изменений во времени. Таким образом, мы (...) высказались за трактовку вопроса о неизменности организации деятельности КРА в соответствии с условиями нового социологического институционализма. То есть, дается приоритет когнитивной основе институтов, служащей поддержкой конкретного проявления социального порядка и дающей отличный способ для его понимания. (shrink)

A method of identifying banks’ business models and studying the features of their risk profile, considering the system of indicators featuring the structure of assets, liabilities, income, expenses, and other qualitative indicators based on monthly statistical reporting. Kohonen's self-organizing maps (SOM) are used to process large data sets, revealing objects’ hidden features by forming homogeneous groups according to similar values of a large system of indicators. The choice of the system of indicators that play the most significant role in describing (...) the business models of modern banks is substantiated. The proposed method makes it possible to group banks with homogeneous characteristics into so-called structural-functional groups and studies the change in the characteristics of groups of banks over time to compare their behavior during periods of active development of the system and during a crisis. That approach is useful for studying the banking system at the macro level, as it provides a quantitative measure of its financial stability. The more banks are in groups with negative values of parameters, increased risks, and unprofitable performance, the worse the general state of the system. The method also allows studying the features of each structural and functional group and the business models’ features at the meso-level. The number and composition of banks inherent in any group change dynamically, which characterizes the features of the relevant business model in a particular period. The averages of each group reflect the objective changes in the banking system structure. In addition, the SOM trajectory can be built for each individual bank determining the development of its strategy, features of a particular business model, and risk profile. At the micro-level, it allows comparing the features of individual banks within the SFGB and models ways to improve efficiency and financial stability by forecast values for SOM. An extensive system of indicators used to form structural and functional groups of banks allows to quickly respond to changes in the banking system, identify areas of increased risk and explore the adequacy and effectiveness of banks’ business models.

The need for innovative development of healthcare institutions is determined by the necessity to increase the efficiency of organizational processes based on the formation of new models of cooperation, which will make it possible to get access to new technologies and knowledge. The goal of the study is to determine the parameters of the impact of innovative open cooperation strategy and the strategy of innovative closed cooperation of healthcare institutions on the effectiveness of their organizational structure in the context of (...) dissemination and the use of knowledge. Simulation modeling was applied to generate the most effective organizational management structure in the context of innovative cooperation and knowledge exchange within the organizational processes “Inside-out” and “Inside-in”. It is substantiated that the strategies of innovative cooperation “Open Innovation/Closed Innovation” have a significant impact on the organizational structure of management of healthcare institutions in terms of the “degree of centralization” (Dci), “degree of mediation” (Dii), and “degree of centralization of powers” (Dpi). The values of the selected criteria range from 25,52% to 61,50% in the case of Dii, and from 34,53% to 52,63% in the case of Dci, which indicates a higher efficiency of organizational knowledge exchange processes in healthcare institutions, which adhere to the Open Innovation strategy of innovative cooperation. Therefore, there are significant differences in the effectiveness of the management’s organizational structure depending on the degree of openness of innovative cooperation of healthcare institutions. The strategy of innovative openness allows increasing the number and quality of connections in the context of knowledge exchange between the subjects (actors, agents) of the organizational structure (in a broad sense, considering internal and external levels of externality) of healthcare institutions, regardless of the distance between them and the level of similarity.

У статті висвітлено сучасні підходи до банківського нагляду, орієнтовані на дослідження бізнесмоделей банків та профіль їх ризиків. Підходи до визначення режиму нагляду та заходів впливу до банків мають враховувати особливості їх фінансового стану та міста на ринку банківських послуг. Інструментарій нагляду має бути об’єктивним і прозорим. Впровадження інноваційних методів визначення бізнес-моделей та адекватних наглядових дій особливо актуальне у період нестабільності банківської системи України. За останні десять років кількість банків суттєво скоротилася. Причиною банкрутства більшості банків були реалізовані кредитні, валютні ризики та (...) ризик ліквідності. Остання криза суттєво підвищила вимоги до методів оцінювання фінансової стійкості банківської системи. Національний банк України постійно вдосконалює процедури оцінювання якості активних банківських операцій, адекватності регулятивного капіталу, достатності основного капіталу та визначення необхідного рівня нормативів достатності капіталу з метою сприяння фінансовій стабільності. У той же час, визначення бізнес-моделі залишається доволі суб’єктивним. Аналіз бізнес-моделей банків має враховувати детальні характеристики їх активів, пасивів, доходів та витрат. У статті запропонована методика структурно-функціональних груп банків на основі самоорганізаційних карт Кохонена. Методика є достатньо прозорою та ефективною. Групи банків із однаковими бізнес-моделями поєднуються навколо екстремальних значень фінансових показників, у відповідних сферах підвищених ризиків. Ця стаття обґрунтовує необхідність широкого охоплення показників, що характеризують банківські ризики. Формування бізнес-моделей банків має визначатися характеристиками банківської системи у конкретний період. Характеристики структури активів, пасивів, доходів, витрат та інші фінансові показники банків відображають особливості стану банківської системи та конкретних банків. Для обробки великих масивів даних пристосовані методи нейронних мереж - самоорганізаційних карт Кохонена. Проведене дослідження рекомендує центральним банкам використовувати чітку технологію формування та аналізу бізнес-моделей. Суб’єктивні підходи до оцінювання фінансової стійкості та вибору режиму нагляду за банками порушують принцип незалежності центрального банку, оскільки припускають вплив різноманітних неекономічних чинників.

The Ukrainian PFTS stock index volatility reaction as a whole and its constituent economic sectors (“Basic Materials”, “Financials”, “Industrials”, “Oil & Gas”, “Telecommunications”, “Utilities”) to seven non-monetary US information signals (“Consumer price index”, “Personal spending”, “Unemployment rate”, “Gross domestic product”, “Industrial production”, “Consumer confidence”, “Housing starts”) was carried out for the period 2000–2017 on the basis of closing stock quotations in the trading day format. To assess the “surprise” component direct influence nature of the USA selected non-monetary information signals on (...) the PFTS stock index, an AR-GARCH econometric modelling device was used. The results achieved clearly indicate the presence of some PFTS stock index economic sectors heterogeneous reaction to the United States individual non-monetary information signals announcement. For example, such economic sectors as “Basic Materials”, “Financials”, and “Oil & Gas” volatility response to the US non-monetary information signal “Consumer price index” “surprise” components the opposite of the overall PFTS stock index reaction. It can also be concluded that the United States non-monetary information signals influence on the Ukrainian stock market volatility depends not only on the financial cycle phase and data frequency, but also on the PFTS stock index economic sector.

The stronger the level of economic integration between countries, the greater the need to study the formation patterns of the stock market reaction to the financial information signals. This concerns the Ukrainian stock market, which is now in its infancy, and which reaction to financial information signals is sometimes ambiguous. The research aims to identify the formation patterns of return and volatility indicators of the Ukrainian stock market reaction to the US financial information signals. To assess the direct nature of (...) US financial information signals effect on the PFTS stock index, the GARCH econometric modeling toolkit was applied. The research information base is the PFTS stock index and the Federal Reserve System financial information signals at the discount rate for 2000–2019. The fetch is divided into intervals corresponded to the ascent and decline phases of the financial cycle. It was found that an unforeseen increase in the discount rate at the financial cycle decline phase by 25 basis points decreases the PFTS stock index return, on average by 2.9%. Besides, the hypothesis about the general change stabilizing effect in the discount rate on the Ukrainian stock market volatility at the financial cycle growth phase was confirmed. Nevertheless, for investors, the most essential is the regulator’s monetary signals in the discount rate at the financial cycle decline phases rather than at the ascent phases because there is a more significant increase in the volatility level.

Using the European assessing indices and the national ones, a new ranking system is created. The authors ranked 20 biggest Ukrainian banks by assets and grouped them into corresponding financial groups.

The study aims at determining the role and significance of such moral emotions as nobility, gratitude, admiration for the socially significant behavior of a person in society. That involves identifying a close relationship between those emotions and personality’s social behavior and that they can be one of the main incentives for socially significant behavior – theoretical basis. The importance of ethical emotions with positive valence when making decisions with their implementation in society determines the research’s theoretical and methodological basis. Those (...) are studied in the cognitive dimension of human social activity, considering their subjective experience and objectification. The authors determined that ethical emotions with positive valence, pleasant emotions stimulate a person to experience them again and behave socially desirable as such behavior allows reliving those emotions and self-actualizing. Emotions with a positive valence are most desirable for a person and are the essential behavior incentives in society. A person can act actively to achieve them, to experience them repeatedly, which is the basis of motivation for socially desirable and meaningful behavior. From exclusively subjective experiences, those emotions move into objectification, i.e., those motivated to act in conditions of a definite or indefinite social continuum. In due time, these socially crucial actions acquire normative content, sometimes even a form, since they serve as a model for others. Moral emotions with positive valence, empathy, rule-making, high culture, and responsibility to oneself and others form a good way of a person’s self-realization through positive social behavior. Furthermore, moral emotions with positive valence are the most important incentive for such behavior. (shrink)

Цель. Работа посвящена определению характерных особенностей влияния экономических информационных сигналов США посредством каналов трансмиссии на компоненты декомпозиции избыточной доходности украинского рынка акций (на примере репрезентативного фондового индекса ПФТС). Методика. Для выявления параметров изменений избыточной доходности биржевого рынка акций Украины в реакциях на экономические информационные сигналы было применено векторное авторегрессионное моделирование. Выбор модели VAR (3) был обоснован согласно информационным критериям AIC и SIC. Результаты. В работе установлено, что лишь переменная избыточной доходности (с лагом 3) позволяет прогнозировать определенную долю будущих изменений доходности (...) фондового индекса ПФТС. Тем не менее, коэффициент R² показывает, что задействованные переменные могут объяснить лишь около 7% изменения избыточной доходности фондового индекса ПФТС, что подтверждает достаточно низкую прогнозируемость украинского рынка акций. На основе декомпозиции избыточной доходности фондового индекса ПФТС за период 2000-2017 гг. (формат торгового дня) было выявлено, что рынок акций Украины является чувствительным к информационным сигналам по будущей избыточной доходности, поскольку более 89% от общего ее изменения можно объяснить влиянием непосредственно через канал премии за риск. Также установлено наличие влияния макроэкономического информационного сигнала США «Индекс доверия потребителей» на избыточную доходность украинского фондового индекса ПФТС через канал премии за риск, что подтверждает предположение о том, что «эффект неожиданности» макроэкономических сигналов США может быть фактором риска для рынка акций Украины. Научная новизна. Получил свое развитие методический подход по определению параметров реакции компонент избыточной доходности фондового индекса ПФТС на «эффект неожиданности» информационного содержание макроэкономических сигналов США. Практическая значимость. Использование приведенного методического подхода позволит улучшить точность финансового прогнозирования параметров реакции ценовых котировок отечественного рынка акций на обнародование макроэкономических информационных сигналов США, что даст возможность инвесторам (частным и институциональным) повысить доходность собственных инвестиционных стратегий.

The article investigates the main characteristics of the financial stability of Ukrainian banks, their risk profile, structure of assets, liabilities, income, expenses based on the monthly reporting data for 2004-2020 (number of observations – 3 813). The Kohonen self-organizing map (SOM) toolkit is used to form homogeneous groups of banks based on a large number of financial indicators. The selected toolkit provides a convenient visualization of the results. Each bank occupies a specific place on the SOM. The close location of (...) banks on the map indicates that these banks have many common characteristics. This study is called the method of structural and functional groups of banks. The study formed stable groups of banks with the same characteristics of business models and risk profile. The formation of consecutive maps for each reporting period allows to obtain the characteristics of each bank separately and the banking system as a whole. The trajectory of an individual bank’s activity during the observation period characterizes the development of its business strategy. The migration of a large number of banks between groups reflects the objective changes in the conditions of banking. Increasing groups of high-risk banks indicate systemic problems. The results show that after a significant reduction in the banking system of Ukraine in 2014-2016, the business models of banks have changed significantly. The resource base relies on unstable sources of current funds with no set term of use. In the assets of banks, a significant portion is invested in government securities – government bonds. Bank loan portfolios have declined and have a higher proportion of non-performing assets (NPL). Many banks have increased currency risk. Concerns are raised about the state of large state-owned banks that hold a separate high-risk group. Thus, the conducted research allows to distinguish groups of banks with specific characteristics of business models and to observe changes of risk profile inherent to these groups. For each structural-functional group, changes in the values of financial indicators are investigated and migration between groups is studied. The proposed methodology is useful for studying both macro and macro levels. (shrink)

Відсутність точної відповіді на питання щодо появи тих або інших соціально-етичних норм може частково пояснити чому моделі соціальних переваг часто розглядаються як ad hoc (в тому сенсі, що висновки, які отримуються в рамках таких моделей, безпосередньо ґрунтуються на висунутих в таких моделях особливих припущеннях), а формалізація моделювання процесів економічної поведінки часто співвідноситься з існуванням певної норми економічної поведінки в контексті досягнення рівноважного стану.

The study based on the available key principles of the circular economy functioning proposes a conceptual scheme of the circular economy ecosystem, which includes key elements such as the country’s population, investments, emissions, and GDP. The ecosystem also considers nine key principles of circular economy functioning, namely: refuse; reduce; reuse; repair; refurbish; remanufacture; repurpose; recycle; recover, which are integrated into functions and supported by them, namely: mining; production; consumption, service; reuse; processing; utilization, forming a chain of a closed cycle of (...) usage of the raw materials, goods, and resources. The study also proposed a conceptual system-dynamic model of the circular economy ecosystem functioning, based precisely on its functions, presented in 7 blocks of the model. Each block covers the influence of circular economy principles on the model’s indicator elements. According to each block of functions, the authors offer opportunities to form new organizational structures that will support the viability of the circular economy concept, provide waste minimization, additional service and processing of goods and waste, and allow the closing of the cycle from extraction to disposal. Further research established the simulation experiments’ specifics and the opportunity to build the model blocks. (shrink)

In the final chapter of the monograph «Influence of macroeconomic announcements on the economic security of Ukraine in the context of globali-zation»( R. A. Pavlov, A. G. Lemberg) theoretical aspects of the influence of macroeconomic announcements through transmission channels on the economic security of the state are considered, decomposition of macroeconomic announcements in the context of determining the scale and nature of their impact on such a component of economic security of Ukraine as financial security is implemented. The choice (...) of a number of key Ukrainian non-monetary announce-ments concerning inflation and the macroeconomic situation of the country when studying the parameters of vulnerability of financial security of Ukraine by the component "Security of the non-bank financial market" in front of the internal economic factors is substantiated. Scientific and methodological approach to assessing the impact of EU and US macroeconomic announcements on the stock market of Ukraine was improved, based on the inclusion of the financial security indicator of Ukraine "Volatility Index of the First Stock Trading System" in the specification of econometric GARCH-model. The methodological toolkit for asse-ssing the impact of the suspense factor of monetary decisions of the National Bank of Ukraine on the discount rate on the domestic stock market on the basis of using the consensus forecast indicator has been improved.

Purpose The purpose of this paper is to determine relation between marketing expenses and bank’s financial position. Factor and cluster analyses were applied to unify different financial variables into financial clusters. Each cluster has specific long-term and short-term financial position and is allocated to appropriate rating position of new rating system. Using rating positions, it is possible to determine whether overall bank position is fragile or stable, and which financial position is vulnerable. Comparing marketing expenses with financial positions, it is (...) possible to evaluate how effectively banks manage their financial resources, and what impact marketing activity has on the financial position. -/- Design/methodology/approach Financial statements of Ukrainian banks for last five years are analyzed. Database of financial documents are reviewed. Coefficient, principal components, and hierarchical cluster analyzes are applied to elaborate new rating system. “Bartlett’s Test of Sphericity” and “Kaiser-Meyer-Olkin Measure of Sampling Adequacy Test” validate input data. Box-and-whisker plots are used to describe graphically interaction between marketing expenses and bank financial positions. -/- Findings The new rating system describes short-term and long-term bank financial positions. In their marketing activity, Ukrainian banks mostly have uneven distribution of marketing expenses in context of financial positions. Such pattern disrupts long-term stability of Ukrainian banking system. Each financial variable has different impact on marketing activity; however, the correlation level is insignificant. In general, Ukrainian banks do not consider financial positions in marketing planning. -/- Practical implications New rating system can be used by the National Bank of Ukraine, the main supervisory bank of Ukraine, to determine fragile banks and to predict their bankruptcy. Banks may use findings to analyze their financial positions and to find optimal marketing expenses. -/- Originality/value This paper contributes into the scientific literature in novelty of marketing-finance interaction in the Ukrainian banking system. New rating system of Ukrainian banks considers different aspects of bank financial stability: liquidity level, credit risks, deposit portfolio, and bank’s ability to attract additional financial resources on financial markets. Cluster analysis helps to allocate similar financial factors to different clusters and to evaluate financial risks in conjunction. As legal regulations concerning banking market, are also considered, the rating system can be adjusted to different countries. In addition, marketing expenses are analyzed in context of banks’ financial positions. (shrink)

The concept of sustainable development considers environmental, social and economic issues in general. And the goals of resource conservation and socio-economic development do not contradict each other, but contribute to mutual reinforcement. The purpose of this study is to build and test an economic and mathematical model for the formation of strategies for the behavior of an economic entity with an increase in the impact of negative environmental factors. The proposed strategies and their models are based on the income-expenditure balance (...) equation, which takes into account both quantitative and qualitative characteristics. The constructed models are considered in the state space. The research methodology is based on building models in the form of linear combinations of functions of a homogeneous external impact and various spatial combinations of economic sources (sinks). The study makes it possible to assess the dependence of the amount of resources used for life support on the chosen adaptive strategy. Within the framework of the proposed model, it was found that the criterion for the effectiveness of the applied strategy can be an indicator of satisfaction with the state, the preservation of which, simultaneously with the preservation of the size of resources used, corresponds to the direction of optimization. This approach is consistent with the concept of sustainable development. (shrink)

Purpose The purpose of this study is to consider the complementarity of ethics and law with regard to the problem of their common existence in society through the identification of common and different characteristics in the philosophy of I. Kant. -/- Design/methodology/approach This study is based on the observation that in modern society ethics and law remain the main social regulators and their co-existence requires the definition of their interaction and complementarity. Also, as this problem is closely related to issues (...) of freedom and obligation, it is necessary to show their role in ethics and law. -/- Findings The results show that the complementarity of ethics and law is due to the obligation that unites them, and the categorical imperative is the only postulate of ethics and the rights to execute, which allows a person to always remain worthy of his name. Ethics also has the meaning of legal capacity, and law means the recognition of people moral independence by public authorities. Thus, the law must protect a person not only from arbitrariness on the part of other people but also from the state power. -/- Originality/value This paper uses a philosophical approach, the utility of which is that ethics and law are studied as elements of normative regulation system of the society in terms of the phenomenal and noumenal nature of a man. It is proposed to consider ethics and law not only as different social regulators, which have their own specifics but also as complementary elements of a single social being, which should exist together and not attempt to substitute one another.

The article analyzes changes in the business models of Ukrainian banks using the author's method of structural and functional groups of banks (SFGB). The method’s basis is the processing, systematization, and visualization of the system’s values of banks’ financial indicators using Kohonen’s self-organizing map (SOM). Depending on the level distribution of a large number of indicators that characterize the structure of assets, liabilities, income, expenses, and other qualitative indicators that describe the business models of each bank on successive reporting dates, (...) homogeneous groups of banks are formed. The purpose of this study is to compare the key features of the banking system as of January 1 and September 1, 2022, and the corresponding changes in business models. Over the eight months of 2022, the number of banks with corporate lending increased slightly, but the resource base of these banks gradually changed. The number of banks with retail financing decreased at the expense of banks with current resources. During an increase in the discount rate and in the price of refinancing loans, banks’ business model that attracts resources on the interbank market and places them in securities has shrunk. At the same time, the number of banks with an increased level of securities in assets and corporate financing increased. The quality of the portfolio indicates the increased credit risks of the respective large state banks. The drawback of the proposed method is the dependence of conclusions on official banks 'statements that do not always reflect nuisances of financial position. Within small banks, we can sometimes observe that current changes in clients' account balances affect the position in SFGB. The SFGB method can be applied to analyze trends and estimate the probability of subsequent structural changes. For each bank, one can observe the trajectory change on the map and investigate the reasons for the change in business strategy. (shrink)

Machine ethics and robot rights are quickly becoming hot topics in artificial intelligence and robotics communities. We will argue that attempts to attribute moral agency and assign rights to all intelligent machines are misguided, whether applied to infrahuman or superhuman AIs, as are proposals to limit the negative effects of AIs by constraining their behavior. As an alternative, we propose a new science of safety engineering for intelligent artificial agents based on maximizing for what humans value. In particular, we challenge (...) the scientific community to develop intelligent systems that have human-friendly values that they provably retain, even under recursive self-improvement. (shrink)

Invention of artificial general intelligence is predicted to cause a shift in the trajectory of human civilization. In order to reap the benefits and avoid pitfalls of such powerful technology it is important to be able to control it.

In this paper, we present arguments as well as supporting evidence from multiple domains indicating that advanced AI can’t be fully controlled. Consequences of (...) uncontrollability of AI are discussed with respect to future of humanity and research on AI, and AI safety and security. This paper can serve as a comprehensive reference for the topic of uncontrollability. (shrink)

The methodological basis of the article is content analysis, comparative, statistical, historical and cultural analysis of Soviet animated works, as well as their characters voiced by (...) Maria Vinogradova. The authors, when considering the problem, achieve the following results: from 1954 to 1995, Maria Sergeevna took part in the dubbing of 213 Soviet cartoons. The most fruitful years for the actress in terms of voice acting were 1976 – 15 works; 1975, 1984 - 12 works; 1973 – 11 works; 1974 – 10 works. For 40 years, the actress has voiced 109 animals, 87 boys, 22 girls, 14 indeterminate characters and 9 inanimate objects. In the process of developing the problem, the authors identify categories of voiced characters (boy characters, girl characters, animal characters, object characters, indeterminate characters) and analyze the actress' creativity for the characters she voices belonging to these categorical elements. The novelty of the research lies in the unconventionality of the indicated approach, as well as in the complex analysis of the palette of Maria Vinogradova's speech capabilities. As a result of the study, the authors come to the following conclusions: 1) The high creative rise of the actress was formed in the 1970s - 91 Soviet cartoons were voiced in this decade, which is 42% of the total number of voiced cartoons. 2) The acting role of Maria Sergeevna's travesty confirms the first place in the number of voiced male characters - children and animals. 3) In 15 cartoons, Maria voiced several characters, and in 2 – all the characters, which indicates a wide speech range of the actress.

Terms Artificial General Intelligence (AGI) and Human-Level Artificial Intelligence (HLAI) have been used interchangeably to refer to the Holy Grail of Artificial Intelligence (AI) research, creation of a machine capable of achieving goals in a wide range of environments. However, widespread implicit assumption of equivalence between capabilities of AGI and HLAI appears to be unjustified, as humans are not general intelligences. In this paper, we will prove this distinction.

This article investigates the proof theory of the Quantified Argument Calculus as developed and systematically studied by Hanoch Ben-Yami [3, 4]. Ben-Yami makes use of natural deduction, we, however, have chosen a sequent calculus presentation, which allows for the proofs of a multitude of significant meta-theoretic results with minor modifications to the Gentzen’s original framework, i.e., LK. As will be made clear in course of the article LK-Quarc will enjoy cut elimination and its corollaries.
