    (Mykolas Romeris university, 2022) Khadzhynova, Olena; Burak, Pavlo; Kalinin, Oleksandr; Калінін, Олександр Володимирович
    This article is dedicated to the study of network viability, the abilities of the entrepreneurial structure, and an analysis of interfirm interactions in the context of the digitalization of the economy. The key goal is to develop a network solvency model as a methodological basis for the most complete assessment of the capabilities of the entrepreneurial structure for effective interaction in an entrepreneurial network in the context of the digitalization of the economy. The theoretical basis of the model was the work of representatives of institutional economic theory, the resource approach, economic sociology, etc. The object of the study was the set of intercompany relations in the business network in the context of the digitalization of economic activity. The subject of the study is the economic relations between business structures regarding the formation and development of inter-firm relations in a network association. The logical and system methods of analysis were used alongside the methods of statistical analysis and expert assessments. The specifics of the problem of determining the factors that affect the ability of economic entities to build effective long-term intercompany interactions in the context of the development of the digital economy determined the structure of the study. It was necessary to analyze approaches to assessing intercompany interactions in a business network in order to identify a number of features and systematize the factors that affect the effectiveness of such interactions. The research algorithm included the following stages: the study of scientific research reflected in the periodical press on the trends in the development of the digital economy; the identification of factors affecting inter-company interactions in the business network in the digital economy; the formation of the authors’ vision of the network viability of economic entities in the digital economy; and the identification and evaluation of the parameters of the network viability of economic entities in the digital economy. The developed model of network consistency is based on the analysis of the space of factors from the standpoint of the relationships between three structural elements that have an indicative, connecting and affirming effect on the development of inter-company interactions in the context of digitalization of economic activity. The pointing element is formed by the resource characteristics of the participants in intercompany interactions, the connecting element is aimed at the competent management of emerging relationships, and the resulting element reflects the synergistic effects that appear as a result of strengthening the interactions of economic entities in the business network.

    False friends? On the effect of bureaucracy, informality, corruption and conflict in Ukraine on foreign and domestic acquisitions
    (Multidisciplinary Digital Publishing Institute, 2022) Honchar, Viktoriia; Гончар, Вікторія Василівна; Kalinin, Oleksandr; Калінін, Олександр Володимирович; Khadzhynova, Olena; McCarthy, Killian
    Ukraine had had its ups and downs in recent years. It has, for example, dramatically improved its ease of doing business (EOBB), and it has made some progress reducing the relative size and influence of its shadow economy (Shadow). But, the Russian invasion of 2014 (Conflict) forced it to take a few developmental steps backwards. In this paper, we consider the effect of these factors, positive and negative, on the number of mergers and acquisitions, involving Ukrainian firms. We construct a sample of 4030 acquisitions in the period 1 January 2000–31 December 2020. Our results suggest that while the number of acquisitions by domestic firms increases in efficiency (+EOBB), transparency (−Shadow) and peace (−Conflict), the number of foreign acquisitions increases in bureaucracy (−EOBB), in informality (+Shadow), and unrest (+Conflict). From an academic perspective, our findings fit with some recent work, while providing new insights too. From a policy perspective, our findings that the number of foreign acquisitions is negatively affected by Ukraine’s attempts to modernize and improve its economy and is positively affected by the ongoing conflict with Russia, makes us wonders what type of ‘false friends’ make such investments.

    Hierarchical fuzzy method of comparing bank products with complex tariff packages
    (University of Tehran, Faculty of Management, 2021) Mints, Aleksey; Zherlitsyn, Dmytro; Khadzhynova, Olena; Kamyshnykova, Evelina; Kalinin, Oleksandr; Калінін, Олександр Володимирович
    The article considers a method for solving an information asymmetry problem that is relevant for the banking sector. The authors compare bank products and services in which tariff packages are consist of different informational components. The principal feature of the proposed method is to focus on obtaining a subjective evaluation of the attractiveness of the Bank’s offers for specific target groups. This makes the proposed method relevant for Central and commercial banks, as well as for consumers of banking products. Since complex tariff packages of different banks contain not only many indicators but also different sets, it is impossible to directly compare them. The proposed method allows solving the main informational problems of traditional methods for comparing banking products. Using the Fuzzy Inference System (FIS) allows a flexible approach to the aggregation of singular indicators of tariff packages and simplifies the expert procedures. To make rules for fuzzy inference, linguistic constructions close to the natural language can be used. This makes it easier to fill the knowledge base. To solve the set tasks, a methodology for constructing hierarchical FIS is used. In comparison with non-hierarchical FIS it can reduce the requirements to the number of rules in fuzzy inference rule base and system implementation time. The experiments with the fuzzy inference system, which implements a corporate credit cards tariff packages comparison of four Ukrainian banks, showed the effectiveness of the proposed approach. The obtained numerical results are adequately interpreted for the highlighted groups of banking product consumers.
