Blockchain technology has emerged as a transformative solution to address specific aspects of emergency management systems by providing a decentralized and distributed ledger infrastructure that enhances data immutability, transparency, and traceability. This study presents a comprehensive bibliometric analysis of blockchain applications in emergency management covering the period from 2017 to 2024 and based on 248 research articles indexed in the Web of Science Core Collection. The analysis examines collaboration networks, co-citation patterns, citation bursts, and keyword trends to uncover key research clusters and emerging themes. Seven major clusters were identified, with their intellectual core built around influential publications that highlight blockchain’s role in improving transparency, efficiency, and trust in emergency response systems. The findings emphasize the growing impact of blockchain technology in enhancing preparedness and resilience during crises while identifying gaps in global collaboration and interdisciplinary innovation.

The EU is currently Ukraine’s largest trading partner. The European market is characterized by high solvency and capacity, which creates many opportunities for Ukrainian exporters. The article examines the transformation of trade flows between the European Union and Ukraine in the context of increased security risks caused by Russia’s full-scale military aggression against Ukraine. An analysis of the main changes in the structure of Ukraine’s foreign trade was carried out, including the reorientation of export and import flows to EU markets. A significant unevenness in the concentration of Ukrainian exports to EU countries was re vealed, which makes its economy more vulnerable to external shocks and points to the available opportunities for increasing exports to other EU member states. An assessment of the economic benefits and challenges faced by both sides was carried out. On the basis of the conducted SWOT analysis, opportunities for trade cooperation between the EU and Ukraine in the conditions of transformation of trade flows were identified.

The paper investigates the economic dynamics of peripheral regions in Europe. There are no consensus among researchers and practitioners concerning the long-term trends of spatial disproportions among European regions. Though there are obvious evidences of inter-national convergence in the EU, the inter-regional convergence is still a challenge. Thus, territorial cohesion and balanced regional development becomes the main tasks of the EU Territorial Agenda. The main purpose of the paper is to inspect the ability of peripheral regions to demonstrate the tendency for anticipatory growth. The authors investigate the theoretical backgrounds of peripheral emergence, make a review of the empirical researches on regional peripheralization in Europe and analyze the quantitative indicators of European periphery’s dynamics. The conclusion is made that there is a strong tendency toward the emergence of new growth poles to the east of "Blue Banana", the traditional European economic spine.

The paper develops the concept of regional monetary integration, the framework of which includes three alternative exchange rate arrangements: currency board, full or parallel dollarization and currency union. Each of them has its own peculiarities of formation and development, its own advantages and disadvantages, but the common feature is unconditional exchange rate unification. The concept of currency proto-integration was introduced, which foresees the exchange of information on monetary initiatives between monetary authorities, consideration of counterparties’ interests to minimize risks or maximize common benefits in the field of monetary relations. In order to assess the effectiveness of monetary integration for the development of intra-regional trade flows, we use gravity modeling based on a sample of more than 105 thousand observations of bilateral trade flows within monetary integrational and proto-integrational alliances. Gravity model includes the parameters of the volumes of bilateral trade, gross domestic product, weighted distances between states and the system of dummy-variables for the determination of monetary associations, common language and borders between trading states. The applied gravity model demonstrates a fairly high level of certainty for South America, Europe, South and East Asia (R² for them was 0.71, 0.63 and 0.54, respectively). It was established that among the monetary alliances, the integrational and proto-integrational structures of South America, Asia and Europe were most effective in the aspect of intensifying intraregional trade. Between the African monetary blocks, the regular growth of mutual trade was observed only in the West African Economic and Monetary Union, while the rest was characterized by reverse dependence.

Analysis of the advantages and disadvantages of indicators of the internal rate of return and the modified internal rate of return as criteria for the effectiveness of an investment project. The mathematical and graphic apparatus for studying the functions and dependencies between the economic characteristics of future financial and production activities of entrepreneurial activity was used in the process of the analysis of the most important indicators of the effectiveness of the investment project. The characteristics of the criterion of the internal rate of return are studied on the basis of the properties of the function which describes the dependence of the net present value of the project on the value of the discount rate. The main advantages of the modified internal rate of return in comparison with its unmodified analogue are revealed. The inequalities between the indicated indicators are mathematically proved, their influence on the stability (safety) characteristics of the investment project is analyzed, and the interrelation of the criterion of the modified internal rate of return with the value of the profitability index is shown. The scientific novelty consists in the mathematical proof of the interrelation between the indicators of the internal rate of return and the modified internal rate of return, as well as the interrelation between the criterion of the modified internal rate of return and the profitability index of the investment project. Theoretical conclusions and suggestions can be used in the investment analysis of future financial and production projects in the domestic economy, which opens up the possibilities of rational use of resources in entrepreneurial activity at all levels of business process management.

In wartime, the role of international assistance and foreign direct investment in ensuring Ukraine’s economic sustainability has increased. The study examines foreign direct investment (FDI) and international financial assistance as key factors contributing to economic growth. The structure and dynamics of international aid in Ukraine are reviewed. A regression analysis was conducted to determine the impact of international aid (particularly, international development assistance) and FDI on the gross domestic product of Ukraine. The results of the study show a positive impact of both performance parameters, while their values are significant and significantly higher than zero. However, FDI flows have a greater impact on GDP than international development assistance. This suggests that international aid is important for maintaining stability, while FDI has a more significant long-term impact on Ukraine’s economic development, especially in the context of integration into the global economy and attracting innovation.
