This article summarizes the arguments and counterarguments in the framework of the scientific discussion on the problem of identifying, using the Granger test, the components of macroeconomic stability of Ukraine most sensitive to the destructive impact of Covid-19. The study's primary goal is to select from among many macroeconomic indicators precisely those that cause epidemiological surges in morbidity and mortality of the population using the example of the Covid-19 pandemic. The systematization of literary sources and approaches to solving the problem of finding determinants that affect the course of the pandemic shows many views among the scientists of the world. Still, they do not establish a single opinion. The study of the topic of identifying the influence of indicators of macroeconomic stability on the destructive impact of the pandemic in work is carried out in the following logical sequence: 1) systematization of literary sources according to the topic of the study; 2) creation of a statistical database that meets the requirements of the chosen methods; 3) bringing the obtained time series to a comparative form and achieving their stationarity; 4) conducting a two-sided test to identify causality. The methodological tools of the research methods were the Dickey-Fuller test for detecting a unit root and stationarity of a series, ways to achieve stationarity of a series using different methods, and a two-sided Granger test for detecting the causality of indicators. The object of the study is Ukraine; the term of the study is the beginning of the pandemic from February 2020 to December 2021. The article presents the results of an empirical analysis of the identification of the components of macroeconomic stability of Ukraine most sensitive to the destructive impact of Covid-19, which showed that such indicators exist and the causal relationship exists in both directions. The study empirically confirms and theoretically proves that the most influential factors are the consumer price index and inflation, which cause the variability of the number of infected and deaths in Ukraine. The study results can help create regional and national patterns of resistance to the destructive impact of the pandemic on macroeconomic stability.

The article examines the cases of 18 countries that have been consistently ranked by Esports Earnings over the past ten years to find the social and economic determinants that may determine a country's success in the international e-sports arena. In the study, indicators of a country's cybersports success consider the annual volume of prizes won by its e-sportsmen, the ranking place in the world rankings and the total number of e-sportsmen. The hypothesis about the possible influence of a number of macroeconomic indicators, as well as the characteristics of the overall level of social stability on the development of e-sports within the country, was put forward and verified. The scientific landscape of research on cybersports, published in Scopus (by prevailing research topics, the geography of research network leaders, and the evolution of scientific search), was structured using the VOSviewer toolkit. By means of canonical analysis, pairwise relationships in the chain "economic development – social development – e-sports development," as well as determinants with strong intragroup and intergroup relationships, have been revealed; and these relationships were quantified in the aggregate by means of structural modeling. The results of the calculations showed that the economic stability of the country rather than social stability has a greater influence on its success in the international e-sports arena. The most relevant indicators of economic development, considering success in e-sports, are GDP, unemployment rate and direct foreign investments, social development – poverty rate, population migration and Gini coefficient.
