Environmental Kuznets Curve: Conclusive Econometric Evidence for

This paper begins with a statistical formulation of the Environmental Kuznets Curve (EKC) and discusses the major econometric problems raised in the literature in testing this hypothesis using panel data. A simple t-test is then presented that avoids these econometric problems. The result from applying the t-test confirms conclusively the EKC for CO 2 as formulated.
