Special Issue Information

Dear Colleagues,

The pandemic created special economic constraints both in the supply and demand domains. The central banks and governments took special measures to control the pandemic and protect the economy. This generates very special conditions which form a very intriguing research field.

The COVID-19 pandemic we are currently experiencing globally has led to the introduction of unusual constraints on the economy and on society, with governments around the world taking extreme special measures and introducing unusual constraints on their population in an attempt to curb the disease’s spread but also, at the same time, to protect the economy. This situation is completely unique and as such serves as an opening for a new, wide field of research. The main question behind this field is what kind of measures should be taken to ensure sustainable development for the economy but also for society. In this Special Issue, we address this question to economists, sociologists, sociophysicists, econophysicists, and other scientists who would like to present their points of view.

The business figures linked to the economy of big companies have shown that large technology platforms are some of the few major beneficiaries of the global economic crisis generated by COVID-19. The study compares biannual results of digital consumption and links user monitoring methods with the realization of qualitative focus groups. It analyses the evolution of the consumption of digital tools (mainly social media) by young university students in Spain between 2019 and 2021. The results of the comparative study show a 36% increase in the time spent using digital applications between the two years studied, as well as a greater concentration of time spent on a few platforms. The qualitative results indicate a self-declaration of addictive dependence on the use of social media; an increasing trend in declaring that youngsters have no interest in stopping their use of these platforms, and a justification that technology companies may not pay the user for the content and data they subsequently use to generate revenue in exchange for personal privacy. This behaviour describes the consolidation of the attention economy concept, which denotates a discursive appropriation of the university students who justify a part of the economic, social, and cultural domination that the technological giants carry out.

This paper examines interlinkages and hedging opportunities between nine major cryptocurrencies from 30 September 2015 to 4 June 2020, a period which notably includes the COVID-19 outbreak lasting from early 2020 to the end of the sample period. Estimated time-varying correlation coefficients that are based on a TVP-VAR show a high degree of interconnectedness among cryptocurrencies throughout the sample period. Notably, the correlations reach their joint minimum during the COVID-19 pandemic indicating that cryptocurrencies acted as a hedge or safe haven during the stressful period of the COVID-19 pandemic. The cryptocurrency weights of the minimum connectedness portfolio were significantly reduced and their hedging effectiveness varied greatly during the pandemic, implying that investors’ preferences changed during the COVID-19 period.
