Economic development and Environmental quality: The environmental Kuznets curve for water pollution
SHAHPOURI, AHMADREZA; BIABI, HAMED & ABOLHASSANI, LEILI
Abstract
The main aim of this study was to analyze evidence of an environmental
Kuznets curve for water pollution in the developing and developed countries. The study was
conducted based on a panel data set of 54 countries – that were categorized into six groups of
“developed countries”, “developing countries”, “developed countries with low income”,
“developed countries with high income” and “coastal countries”- between the years 1995 to
2006. The results do not confirm the inverted U-shape of EKC curve for the developed
countries with low income. Based on the estimated turning points and the average GDP per
capita, the study revealed at which point of the EKC the countries are. Furthermore, impacts
of capital-and-labor ratio as well as trade openness are drawn by estimating different models
for the EKC. The magnitude role of each explanatory variable on BOD was calculated by
estimating the associated elasticity.
