This paper estimates the linkages among total Sulphur dioxide (SO2) emissions, total GDP and energy efficiency using China's provincial panel data from 2002 to 2015. We investigate total emissions rather than per capita emissions or ambient concentrations, since it is total emissions that the...

The objective of this paper is to establish whether the estimated relationship between environmental degradation and per capita income corroborates the inverted U-shape hypothesis as exemplified by the Environmental Kuznets curves (EKCs) in selected ECOWAS countries. Considering two variants of...

In this paper, we examine the relationship between economic and environmental performance. More specifically, we analyse the impact of SO2 reduction in the eighties (1980-1992) on productivity growth, technical efficiency and technological progress for a set of 12 OECD countries. Our timeframe...
