摘要：Recent literature proposes many variables as significant determinants of pol-
lution. This paper gives an overview of this literature and asks which of these
factors have an empirically robust impact on water and air pollution, i.e. do
not depend upon the conditioning information set. For this, we apply Ex-
treme Bound Analysis (EBA) on a panel of 208 countries covering the period
1960–2001. We find supportive evidence on the existence of the environmen-
tal Kuznets curve. Furthermore, mainly demographic variables and variables
capturing the economic structure of a country contribute in explaining air and
water pollution
