The COVID-19 pandemic and main economic convergence indicators in the EU.

>The outbreak of COVID-19 pandemic caused an unprecedented global public health crisis, which led to a drastic decline in economic activity and sharp rises in government deficits and public debts. Our research aims to analyse the aggregated impact of COVID-19 pandemic on each EU country and their health systems and correlate it with the main economic convergence indicators for 2020. To this purpose, we built a composite COVID index using Principal Component Analysis, employed TOPSIS to rank the EU countries according to nominal and real convergence indicators, and correlate the index with each ranking. Our findings suggest that in the first year of the pandemic, nominal convergence indicators were more affected than real convergence indicators. Non-euro CEE countries managed to keep some of their convergence indicators at relatively sustainable levels despite having high COVID index values. Baltic and Scandinavian countries seem to have outperformed the others, the latter having an initially more relaxed approach to the restrictions imposed on the population. The risk of diverging during the pandemic crisis appears to be increasing in countries where there were imbalances prior to 2020. [ABSTRACT FROM AUTHOR]
