    This paper examines whether environmental and social (ES) activities affect the resiliency of firms during the COVID-19 crisis. We study a sample of 330 firms operating in five developed countries: Canada, France, Japan, the UK and the US. Our analysis shows that US firms with a high ES ranking experienced a significantly lower stock price range volatility during the Covid stock market rundown of February-March 2020. Such findings also hold for Japanese firms but only later on after the introduction of government support. In terms of returns, compared to their peers with a low ES ranking, Japanese and UK stock prices with a high ES ranking suffered more during and after the market rundown. For other countries, we do not find significant differences in stock price behavior based on ES ratings. Our findings suggest that engaging with ES activities is not associated with a better or worse performance during crisis times, which has important implications for investors and managers.

    The year 2021 marked the 200th anniversary of the 1821 Revolution against the Ottomans, which eventually led to the formation of the modern Greek state. In order to celebrate the momentous occasion, a special committee called Greece 2021 was formed to organize the national festivities of the bicentenary commemoration in March 2021. Greek businesswoman Gianna Angelopoulos-Daskalaki, best known as the president of the bidding and organizing committees for the 2004 Athens Olympic Games, served as the head of Greece 2021. Many prominent business people, mainstream academics, cultural figures, and historians participated in the committee. For the right-wing government of Kyriakos Mitsotakis that organized the celebration, as well as for the economic elite connected to it, this was a great opportunity to stage a series of events that would boost its popularity and occupy the news agenda. But things didn't go as expected because of the Covid-19 pandemic and the social, economic and political tensions that it triggered. The majority of the planned events were cancelled, leaving plenty of room for the dissemination of controversies around the 1821 bicentenary in social media that largely countered the official agenda. In this paper we propose an original method combining large scale network and lexicometric analysis in order to link identifiable communities of Twitter users with the main discursive themes they used around the 1821 revolution bicentenary. This in order to distinguish the political and cultural issues and cleavages within Greek society that were made visible on Twitter on the occasion of this event.

    This paper questions whether firms’ internet connectivity and adoption helped them cope with the COVID-19 pandemic. Using data on 31,387 firms from 39 developing and developed economies, our results stress that businesses using website before the crisis showed higher absorption capacities than other firms during the crisis. The positive role of website use was mainly through the adoption of coping strategies, in particular home-delivery services, online sales or remote work. In contrast, the positive effect played by the prior use of internet is not explained by better access to external public (government support) or private (bank loan) financial resources. If prior internet use had a role on the resilience of firms, this is not the case for internet access. A negative effect of firm survival and labour adjustments is indeed found, but further analysis shows that this finding is explained by the mediating effect of 4G coverage on COVID policies’ stringency, suggesting that these policies were more effective in places with better internet coverage.

    Using the United Nations Comtrade database, we perform the Google matrix analysis of the multiproduct World Trade Network (WTN) for the years 2018-2020 comprising the emergence of the COVID-19 as a global pandemic. The applied algorithms -- the PageRank, the CheiRank and the reduced Google matrix -- take into account the multiplicity of the WTN links providing new insights on the international trade comparing to the usual import-export analysis. These algorithms establish new rankings and trade balances of countries and products considering every countries on equal grounds, independently of their wealth, and every products on the basis of their relative exchanged volumes. In comparison with the pre-COVID-19 period, significant changes in these metrics occur for the year 2020 highlighting a major rewiring of the international trade flows induced by the COVID-19 pandemic crisis. We define a new PageRank-CheiRank product trade balance, either export or import oriented, which is significantly perturbed by the pandemic. Comment: 22 pages, 2 tables, 13 figures, 2 appendices

    This article introduces the approach of economics and sociology of conventions (in short EC) as a neopragmatist institutionalism in the field of economics and sociology of health. For EC, conventions are regarded as institutional logics of valuation, valorization, and coordination, and EC emphasizes the empirical plurality of orders of worth and values actors rely on and institutions are built on. In particular, health, health care, and its institutions are closely linked to value issues and norms. Because of the pluralism of possible value systems and orders of worth, tensions and critiques are an important empirical phenomenon to be addressed in the health care system. The contribution sketches main positions and perspectives of EC in the analysis of values, medical professions, and ethics of datafication, quantification, classification (related to health and health care institutions), and of social inequalities as well as in the analysis of health policies and health capitalism. Furthermore, the COVID-19 pandemic and its consequences are discussed from the standpoint of EC and, finally, social trends and perspectives in times of the pandemic are outlined.

    La crise du COVID-19 a mis en évidence la carence de l'assurance des pertes d'exploitation, en cas de pandémie de dimension mondiale. De telles pandémies sont des événements de nature systémique, et c'est ce qui les distingue des autres risques catastrophiques comme les catastrophes naturelles ou les accidents industriels majeurs. Ce caractère systémique rend impossible leur mutualisation par les mécanismes usuels d'assurance ou de réassurance. Face à ce défi, la capitalisation, jusqu'ici limitée à l'assurance-vie ou à la prévoyance, offre des perspectives nouvelles au risk management des entreprises, avec un rôle important et nouveau pour le secteur de l'assurance.

    AIMS. To determine the contribution of social distancing and face mask wearing in the prevention of COVID-19 infections in Argentina. METHODS. Attendance to the funeral of ex-soccer star Diego Maradona was estimated by the area occupied by the mourners and their density. The people congregated to celebrate the America's Cup victory was deduced mainly from TV ratings. The proportion of individuals wearing or not face masks was calculated from photographs taken at both events. The COVID-19 epidemiological data used was released by the Argentinean Ministry of Health from March 3 rd 2020 to August 31 st 2021. RESULTS. We estimated that Maradona's funeral was attended by approximately 250,000 mourners. Approximately 5.083.958 followed by television the America's cup final in Buenos Aires alone. Extrapolating to the whole country suggests that over 4 million individuals congregated in person to celebrate the victory. The percentage of individuals not wearing face masks at the funeral was 54.0% ± 5.2 % and at the soccer victory celebrations 84.5 % ± 6.9 %, both estimates with a confidence of 99%. Daily COVID-19 infections in Buenos Aires remained at less than 5,000 per day during 30 days before-as well as during 24 days following-the funeral. New infections in Argentina remained less than 21,000 during 10 days before as well as 30 days following the soccer cup celebrations. CONCLUSIONS. Considering that SARS-CoV-2 median incubation is 5.1 days, the time periods following Maradona's funeral and the America Soccer Cup celebrations provided ample time for COVID-19 to flare up if significant contagion would have proliferated amongst the crowds. The lack of an increase in COVID-19 infections after two independent and large gatherings with people in close proximity and limited wearing of face masks, raises questions about any beneficial effect of social distancing and of mask wearing during the pandemic.

    Prix du meilleur second choix dans la catégorie recherche lors de la conférence UIIN.; International audience; To leverage the emerging potential of new technologies, digital transformation has been a clear priority for most large- and mid-sized organizations for over a decade now (Vial, 2019). However, COVID-19 pandemic has recently pushed several microbusinesses (MBs) to hurriedly initiate digital transformation (DT) efforts and keep their businesses afloat (Mandviwalla & Flanagan, 2021). MBs comprise a class of small and medium enterprise category (SMEs) that typically have fewer than 10 employees and lesser resources (OECD, 2021). They represent about 93 percent of all businesses in the Europe (European Commission, 2019). Their economic significance is also shown through ha survey which predicted that by 2024 small businesses through their DT efforts have the potential to add over 2.3 trillion USD to the global GDP, which would be key for the post pandemic economic recovery (CISCO, 2020). Prior research has shown that DT effectiveness varies significantly with firm size (Mandviwalla & Flanagan, 2021). Following these, the aim of our study is to examine to identify the enablers and inhibitors of digital transformation within the MB sector in Ireland.
