“…The novel coronavirus has had an unprecedently effect on the alternative energy sector. Liu et al [43] found that the COVID-19 pandemic had a more significant impact on the alternative energy sector than the global financial crisis did in terms of stock price returns and volatilities. Studies on the impact of COVID-19 on the alternative energy sector indicate the adverse effects of the pandemic during its initial phase.…”

The paper aims to detect the differences in stock market performance between companies from the alternative energy sector and main stock market sectors in the first and second years of the COVID-19 pandemic. We used Global Industry Classification Standard to analyse eleven main stock market sectors and the alternative energy sector. Based on the one-factor variance analysis—ANOVA, we reveal the statistically significant differences between the analysed stock market sectors in both 2020 and 2021. The analysis implied that the performance of stock market companies during COVID-19 is sector-specific. Tukey’s Honestly Significant Difference (HSD) test for pairwise comparison indicates that the alternative energy sector shows the most differentiation. Its average rate of return in 2020 is the highest and is significantly different for all eleven stock market sectors, while the top constituents from the conventional energy and financial sectors suffered the most. In 2021, a reverse trend in the stock prices can be observed. Companies from the conventional energy and financial sectors achieved the highest positive average weekly rates of return among all of the analysed stock market sectors, while the alternative energy sector performed significantly worse than the other sectors did. Nevertheless, throughout the entire analyses period of 2020–2021, the companies from the alternative energy sector turned out to be the biggest stock market beneficiaries. This study might imply that the COVID-19 pandemic has not hampered but has instead accelerated growing concerns about the environment and climate change.

“…There was a negative effect on the quality of the population's mental well-being, an increase in the levels of anxiety, depression and alcohol abuse 5 , and an increase in cases of depression [5][6][7][8] , anxiety [5][6][7][8] , stress [6][7][8] , panic disorder 3 , insomnia 8 , fear 4,7,8 and anger 5 in different populations. The financial losses in this pandemic episode were an additional factor to the psychosocial risk 9,10 ; in particular, suicide rates increased in proportion to a rise in unemployment in Canada 11 , a relationship already described in Brazil in the pre-pandemic period 12 .…”

This article aims to analyze the factors associated with suicidal ideation in the COVID-19 pandemic. A cross-sectional home-based survey, with three-stage cluster sampling, was conducted with 4,203 adults from ten municipalities in the Mato Grosso, Brazil. The data collection was carried households to assessment of sociodemographic characteristics, substance use and behavior in the pandemic. The Level 1 Symptom Cross Scale was used to identify suicidal ideation and aspects of mental health (somatic symptoms, sleep disturbances, dissociation, depression, anger, mania, anxiety, thoughts, substance use and memory). Chemiluminescence was used to detect IgG anti-SARS-CoV-2 antibodies. The prevalence of suicidal ideation was 19.2%, and the associated with increased consumption of alcohol (RP=1.16), smoking (RP=1.30), COVID-19 symptoms (RP=1.03), having one’s life affected (RP=1.04), mental illness (RP=1.09) somatic symptoms (RP=1.15), sleep disturbance (RP=1.30), dissociation (RP=1.24), depression (RP=1.24), anger (RP=1.11), anxiety (RP=1.26), substance use (RP=1.19), drug prescription use (RP=1.18) and memory (RP=1.87). Highlights the high prevalence of suicidal ideation related to COVID-19 symptoms, changes in behavior post-pandemic and mental health factors.

“…We hypothesized a positive association between GDP and stock market index to determine whether stock market index can be a predictor of economic activity using quarterly data. We assume that stock market indices can reflect future expected economic outcomes, as they are made up of an aggregated measure of investment performance and can serve as a sentiment indicator that may reflect on the expected economy [1,[13][14][15].…”

Objective: To estimate the economic impact of border closure and social distancing by estimating the decline of gross domestic product (GDP) in Kenya, Singapore and Thailand.Methods: We analysed secondary data retrospectively. To calculate impact of NPIs on GDP, the relationship between GDP and stock market index was examined using ordinary least squares (OLS). Then, autoregressive and moving averages (ARMA) model was used to examine the impact of NPI on stock market index. The change in GDP due to NPIs was derived by multiplying coefficients of OLS and ARMA models.Results: An increase in stock market index correlated with an increase in GDP, while both social distancing and border closure negatively correlated with stock market index. Implementation of NPIs correlated with the decline in GDP. Thai border closure had a greater decline in GDP than social distancing; Kenya exhibited the same trends; Singapore had the opposite trend.Conclusion: We quantified the magnitude of economic impact of NPIs in terms of GDP decline by linking stock market index and GDP. This approach may be applicable in other settings.
