This paper offers a quantitative assessment of the impacts of the COVID-19 pandemic-induced lockdown and government fiscal plan, containing ‘green’ elements on the economy and the environment of South Africa. The analysis uses a dynamic computable general equilibrium model operationalised using a social accounting matrix coupled with a greenhouse gas balance and emissions data. We find that while the economy is harshly impacted by the pandemic in the short term, the government fiscal package ameliorates and cushions the negative effects on poor households. Importantly, an adaptation of the fiscal package towards a ‘greener’ policy achieves the same economic outcome and reduces unemployment. Carbon dioxide emissions decrease in the short run due to economic slowdown. This improvement persists until 2030. These results can be used as decision support for policy makers on how to orient the post COVID-19 policies to be pro-poor and pro-environment, and thus, ‘build back better and fairer’.

This study analyzes a public-spending option from mining and oil resources and its impact on Niger's economy. The windfall gain from mining and oil revenues provides an opportunity for the country to reinvest natural resource rents, enhance economic development, and address infrastructure gaps. Drawing on the country's recent and expected mining and oil exploitation, we evaluate the effects of a reinvestment policy in road infrastructure using a dynamic computable general equilibrium (CGE) model. We find that investment in road infrastructure brings positive spillover effects to other sectors of the economy and benefits to the economy in the long run. Our analysis additionally shows that reinvestment in road infrastructure, given the initial state of infrastructure in Niger, could help mitigate the resource curse.

Since 2007, Burkina Faso's mining sector has grown quickly, with gold replacing cotton as the country's biggest export. The decline in gold prices since 2012, however, has hit the Burkina Faso economy hard. Using a static computable general equilibrium model, we assess whether – in a context of gold-price decline and volatility – an increase in the tax burden on the mining sector, as implemented by the government of Burkina Faso, is the appropriate way to avoid the natural resource curse. The results show that a tax policy based solely on increasing taxes on the gold sector brings only limited economic benefits, notably in terms of employment, and fails to significantly mitigate the effects of gold-price volatility.
