The Effects of COVID-19 Spread on the Egyptian Exchange Sectors: Winners and Losers across Time (preprint)

Abstract: This paper attempts to investigate the effects of Coronavirus spread on stock markets using panel data analysis, on daily basis over the period from March 1, 2020 until September 30, 2020. Coronavirus spread has been measured by daily cases and daily deaths per million of population, while stock return is measured by Δ in sectoral indices. This has been conducted after dividing the research period into 6 months from March to September and has been applied on 17 sectors in the Egyptian Exchange. Using panel data analysis, results indicate significant negative industry effects for each of banking sector (BANK), Food, Beverages and Tobacco sector (FOBT) and Health Care & Pharmaceuticals sector (HLTH). Besides, findings show significant positive industry effects for each of Contracting & Construction Engineering sector (COCE), Energy & Support Services sector (ENGY), IT, Media & Communication Services sector (IMCS), Shipping & Transportation Services sector (SHTS) and Trade & Distributors sector (TRDB). The robustness check supports the significant negative industry effects for each of Food, Beverages and Tobacco (FOBT) and Health Care & Pharmaceuticals (HLTH) (as losers) and the significant positive industry effects for each of Energy & Support Services (ENGY), Shipping & Transportation Services (SHTS) and Trade & Distributors (TRDB) (as winners).

The impact of COVID-19 and strategies for mitigation and suppression in low- and middle-income countries.

Abstract: The ongoing coronavirus disease 2019 (COVID-19) pandemic poses a severe threat to public health worldwide. We combine data on demography, contact patterns, disease severity, and health care capacity and quality to understand its impact and inform strategies for its control. Younger populations in lower-income countries may reduce overall risk, but limited health system capacity coupled with closer intergenerational contact largely negates this benefit. Mitigation strategies that slow but do not interrupt transmission will still lead to COVID-19 epidemics rapidly overwhelming health systems, with substantial excess deaths in lower-income countries resulting from the poorer health care available. Of countries that have undertaken suppression to date, lower-income countries have acted earlier. However, this will need to be maintained or triggered more frequently in these settings to keep below available health capacity, with associated detrimental consequences for the wider health, well-being, and economies of these countries.

Contact Tracing during Coronavirus Disease Outbreak, South Korea, 2020.

Abstract: We analyzed reports for 59,073 contacts of 5,706 coronavirus disease (COVID-19) index patients reported in South Korea during January 20-March 27, 2020. Of 10,592 household contacts, 11.8% had COVID-19. Of 48,481 nonhousehold contacts, 1.9% had COVID-19. Use of personal protective measures and social distancing reduces the likelihood of transmission.

Governance, technology and citizen behavior in pandemic: Lessons from COVID-19 in East Asia

Abstract: Corona Virus (CODID-19) was first reported in Wuhan in December 2019, then spread in different parts of China, and gradually became a global pandemic in March 2020. While the death toll is still increasing, the epicenter of casualty has shifted from Asia to Europe, and that of the affected people has shifted to USA. This paper analyzes the responses in East Asian countries, in China, Japan and South Korea, and provides some commonalities and lessons. While countries have different governance mechanism, it was found that a few governance decisions in respective countries made a difference, along with strong community solidarity and community behavior. Extensive use of emerging technologies is made along with medical/health care treatment to make the response more effective and reduce the risk of the spread of the disease. Although the pandemic was a global one, its responses were local, depending on the local governance, socio-economic and cultural context.
