The number of studies seeking to empirically characterize the reduced-form relationship between a country's economic growth and the quantity of various pollutants produced has recently increased significantly. In several cases researchers have found evidence in favor of an inverted-U...

This paper casts doubt on empirical results based on panel estimations of an "inverted-U" relationship between per capita GDP and pollution. Using a new data set for OECD countries on carbon dioxide emissions for the period 1960-1997, we find that the crucial assumption of homogeneity across...

In this paper we investigate the existence and shape of the Environmental Kuznets Curve (EKC) by means of nonparametric methods. We also investigate the issues involved in the choice of nonparametric estimator. We find that the nature of the economic relationship and the quality of environmental...

The number of studies seeking to empirically characterize the reduced-form relationship between a country economic growth and the quantity of pollutants produced in the process has recently increased significantly. In several cases researchers have found evidence pointing to an inverted-U...
