Unregulated economic activities and the environment: The role of fiscal policies.

African countries are characterized by high unofficial activities, coupled with a fiscal structure that could either undermine or promote these activities to affect the environment. This study examines the direct and indirect environmental impacts of the unregulated economy and the fiscal instruments of government expenditure and tax using the panel quantiles regression technique. Driven by data availability, our analysis covers 46 countries when the fiscal variables are not considered, while 41 and 38 countries are respectively included in the models involving government expenditure and tax revenue from 2000 to 2016.
