Game-theoretical perspectives on COVID-19 pandemic.

COVID-19 pandemic has raised concerns for a number of strategical social interactions. From quarantines and social distancing to vaccination and geopolitics, the cooperation or even the coordination of efforts has been challenging, as governments, economic sector, institutions, and individuals, often have conflicting interests. Game theory, which is a mathematical tool extensively used in order to determine the outcomes of strategical interactions, has been applied to a number of issues arising from the pandemic. In this paper, 60 publications are analyzed to identify the key contributions of game theory to addressing COVID-19. First, 10 keywords-topic are chosen and each publication is examined to consider if it deals with these topics. Then R package "igraph" and cluster Louvain are used in order to group the papers to 3 clusters. The results indicate that there is a temporal variation in the topics examined. In the beginning the main concern has been coupling the modelling of the transmission of the virus with social distancing responses from the public and quarantining policy. Then the economic implications of the pandemic drew the attention and finally the application of the vaccination campaigns and the cooperation of the individuals with vaccination guidelines. The paper targets on bridging the gap between game theorists and epidemiologists, illustrating how modelling agents interactions can improve responses. The clusters created can help researchers identify groups of problems that can be addressed jointly, using similar approaches. The analysis indicates that game theory can reveal social aspects that can improve the responses to future emergencies. [ABSTRACT FROM AUTHOR]
