Public debt can attract funds to finance public needs and stabilize the country’s economic development. This study aims to analyze the relationship between public debt and economic development considering the war actions in Ukraine. This paper uses bibliometric analysis, comprising in-built Scopus and WoS instruments, VosViewer, and Google Trends tools. The overall results show the close relationship between public debt, economic development, and war (armed conflict) concepts. The publications were examined according to key features: containing the keywords from the green and red clusters; covering the period 2015–2018 and 2022; and discussing public debt in Central and South-Eastern Europe. This improved the theoretical and methodological approach to the bibliometric analysis of public debt. Moreover, the study identified risks (based on selected scientific publications) to which the primary attention should be paid during the war and post-war periods in Ukraine: currency and demographic risks. Key recommendations were provided to ensure debt security during the war and post-war periods. However, the given recommendations should be implemented within the framework of the Recovery Plan of Ukraine, which would improve the credit rating and reliability of the state.

Globalization processes define the modern trends in world economic development, including both international financial markets and the banking systems of different countries. The study aims to evaluate the efficiency of the banking systems of Ukraine and 17 European countries in order to choose the appropriate measures, concerning its increasing. The Data Envelopment Analysis (DEA) was chosen as a tool for evaluating the efficiency of the banking systems; the calculations were made using the Banxia Frontier Analyst software. Also, the BBC and CCR models of linear programming were used to define the existing relationship between the studied indicators. As a result of the study, the groups of efficient and inefficient banking systems were identified, which allowed determining the existing reserves, possible managerial tools and decisions for improving the inefficient banking systems’ performance. Besides, graphical interpretation of the current position (rank) of certain country bank system in relation to other countries’ banking systems was presented. The developed approach is aimed at improving bank management at the macro level and enhancing the efficiency of banking systems.
