“…The literature on the impact of energy commodities on output is well documented ( Ahmad and Du, 2017 ; Aydin and Esen, 2016 ; Kilian, 2008 ; Li et al, 2020 ; Mustapha and Fagge, 2015 ; Nasreen et al, 2020 ; Tang et al, 2016 ; Yan et al, 2021 ; Zhang et al, 2021 ). Energy is the engine of economic growth ( Tang et al, 2016 ; Umar et al, 2020 , 2021a ), and Oil, which contributes one-third of global energy consumption, is considered the main energy source.…”

We examine the time-frequency dynamics of spillovers between oil price shocks and economic performance globally. We use both time and frequency domains simultaneously to find the response of macroeconomic performance to changes in oil prices during the global financial and pandemic crises. Using Wavelet analysis, this seminal study explores the connectedness between oil price shocks and economic activities during COVID-19 and the financial crises of 2008. This study finds that both economic activities and oil prices have shown high power during the period of global financial crises. The recently COVID-19 outbreak indicates significant volatility in economic activities and oil prices during the period of crisis. Moreover, we observe a strong interconnectedness between oil prices and economic activities during global financial crises and COVID-19 crises. We argue that a shock to oil prices in global financial crises and the COVID-19 outbreak has serious repercussions for economic activities. The highest total connectedness between oil prices and economic activities is observed during the COVID-19 outbreak, which advocates that the speed of information transmission amid oil prices and economic activities is greater in the era of the COVID-19 outbreak as compared to other global financial crises. The results of this study have significant implications for policymakers.

Cryptocurrency mining and blockchain technology using renewable energy as the main electricity source has gained attention for sustainable development in financial areas. However, very few studies have been reported concerning the power usage of cryptocurrencies using renewable energy. In this article, we report the effect of overclocking and undervolting on power usage and the hash rate for mining dogecoin with solar energy as renewable energy. The mining rig used in this work consists of different graphics processing units (GPUs) and non-LHR (lite hash rate) cards. The UnMineable software has been used for mining dogecoin as well as for wallet integration. The results indicate that mining dogecoin with solar energy as renewable energy consumes 2000 Watts power with overclocking and 1700 Watts power with undervolting technique. This work implicates the potential future of crypto-mining with renewable energy and the hardware configuration associated with it, which is expected to reduce e-waste and improve sustainable development. To reduce the e-waste and high electricity consumption, we have introduced two important techniques named GPU optimization and use of renewable energy for mining, which helps the miners to reduce the e-waste and electricity consumption significantly at the same time getting most out of the GPU by not having any impact on the environment.

“…Investor sentiment impacts stock returns, as it is confirmed by numerous studies ( Chen et al, 2021 ; Narayan, 2019 ; Su et al, 2020 ; Yan et al, 2021 ). We postulate that when the investors' sentiments cause the market to move down due to a pandemic, government policies that mitigate the effects of the pandemic must have a positive effect on stock returns.…”

In this paper, we investigate the impact of the government economic policies in addition to the more stringent Covid-19 policies on stock index returns of GREF countries, that is, a new economic bloc of 5 countries (Pakistan, Iran, Turkey, Russia, and China) to foster for sustainable development of the region. Using the Panel, ARDL model and data for index returns and economic and Covid-19 control policies for the period March 1, 2020–June 30, 2021, results show that Income support, workplace closure, stringency index, and cancellation of public events have a significant positive impact on the stock index returns over the long run. In contrast, school closure, restriction on public gatherings, and international travel control policies negatively impact stock returns. In comparison, Debt policies, Covid-19 testing policies, health index, and face-covering policies remain insignificant. In the short run, stringent index and face-covering policies remain positively significant. Results of the study suggest significant policy implications that can help reform economic and Covid-19 control policies and promote the region's economic growth over the long-run period.
