In resource-endowed countries, the ability of governments to spend on the critical sectors of their economies depends on the stability of resource prices. Similarly, in crude oil-endowed countries, governments face fiscal constraints during a decline in crude oil prices. Such declines often affect economic performance and mostly result in economic downturns (Raifu et al., 2020). This has been the experience of Nigeria, the largest oil-producing country in Africa. Since crude oil was discovered in 1956 at the Oloibiri village of Niger Delta and became commercialised in the early 1970s, it has become the mainstay of Nigeria’s economy. The survival of Nigeria’s economy largely depends on oil price stability and oil revenue generation.

The moderating role of regulatory quality in the relationship between ICT and financial development in Africa is investigated in this study. We employ data from 38 African countries from 2003 to 2020. For the analysis, a two-step system GMM is used. Our findings demonstrate that ICT and regulatory quality are essential for financial development. The net effect of ICT and regulatory quality on financial development is positive, implying that regulatory quality moderates upwards the nexus between ICT and financial development.

Dozens of studies point to evidence of significant reductions in carbon emissions driven by climate agreements, such as the Paris climate agreement. However, these studies fail to answer a pertinent question, that is, are global carbon emission reductions due to reduced production activities or are production processes becoming more efficient as less carbon is emitted per unit output due to technical progress? Such an understanding is important to evaluate the tension between environmental quality and economic growth.

This study examines the effect of ICT on tax revenue mobilisation in 23 sub-Saharan African countries between 2000 and 2020. To address our objectives, it utilises a feasible generalised least squares approach that accounts for both heteroscedasticity and autocorrelation challenges. Particularly, six measures of ICT (import of ICT goods, export of ICT goods, ICT trade, internet penetration, mobile phone penetration, and aggregate ICT index) and six tax measures (total tax, direct tax, indirect tax, taxes on income, profit, and capital gains, taxes on goods and services, and taxes on international trade) are explored in the study.

While several studies evaluate the impacts of the novel coronavirus pandemic on different markets, it is worth the while to also examine its contagion (fractal) effect on the top (based on their market capitalization) twenty cryptocurrency markets. These cryptocurrency markets’ information (return and volatility) were sampled for both the ex-ante and ex-post coronavirus outbreak periods for this event study analysis. The detrended cross-correlation approaches are employed for both the main and robustness analyses. The results are robust and confirm a significant fractal contagion effect of the pandemic on the cryptocurrency space through their return and volatility. The contagion effect is relatively stronger for the crypto markets’ volatilities compared to the returns, nonetheless. Hence, this study supports the contagious effect of the coronavirus pandemic on the cryptocurrency markets and its policy implications for investors in the crypto space.
