Purpose The COVID-19 outbreak and its confinement resulted in an unexpected stock market crash, hence the interest in environmental, social and governance (hereafter, ESG) policies. This paper aims to examine the association between ESG performance and stock market volatility before and after the COVID-19 pandemic. Design/methodology/approach This paper examined 500 US companies listed in the S&P 500. The window period volatility refers to March 18, 2020, when the US President signed into law the Families First Coronavirus Response Act. Here, the Thomson Reuters database was used to collect ESG data and daily market information. Findings The findings suggest that companies with high ESG performance have lower stock price volatility than companies with poor ESG performance. In other words, strong ESG performance reduces stock price volatility resulting from the COVID-19 shock and promotes resilience and stock price stability. Practical implications This research contributes to current debates on emerging pandemics and unexpected risks and highlights the need to invest more in improving corporate sustainability. Originality/value The results have substantial implications for managers and investors, as it highlights the relevance of customer and investor loyalty to the durability of ESG stocks.

Purpose This study aims to explore the role of mobile tracing applications as part of e-government services in combating the COVID-19 pandemic effects in Africa by analyzing the moderating role of sustainable development. This study also investigated the role of the political and economic systems in mitigating the negative consequences of COVID-19 and how e-government interacts in this relationship. Design/methodology/approach This study included the COVID-19 performance index for 94 countries belonging to different regions, including 20 African countries. Multiple linear regression was used for data analysis via Stata software. The study was conducted from the start of the pandemic to March 13, 2021. Findings The results show that less economically and technologically developed countries with generally authoritarian political systems, including African countries, could limit the spread of the pandemic better than some democratic, economically and technologically developed countries in the first wave of the pandemic. The promotion of sustainable development goals moderates the relationship between mobile tracing applications as part of the e-government service and the fight against COVID-19. Originality/value This study provides insight into the role of mobile application technology as an e-governance service in mitigating the negative consequences of the COVID-19 pandemic in a context characterized by economic limitations, fragile public health infrastructure and relatively high political instability, especially in Africa. The findings shed light on some of the difficulties African countries may face in incorporating technology into their development projects.
