Environmental efficiency in carbon dioxide emissions in the OECD: a non-parametric approach
(Academic Press, 2000) Zaim, O.; Taskin, F.
The role of the environment is an important issue in the policy-making and hence, the accurate assessment of the environmental conditions is vital. In this paper, an environmental efficiency index is developed for the OECD countries using non-parametric techniques. The approach adopted is based on the assumption that there is just one production process behind the production of both goods and pollution emissions. The index derived in this work measures the extent of the required output sacrifice, due to the transformation of the production process, from one where all outputs are strongly disposable to the one which is characterized by weak disposability of pollutants. Using this index, we first conduct cross-section comparisons on the state of each country's production process in its treatment of pollution emissions. We then trace each country's modification of their production processes overtime. The results indicate that if the disposability for CO2 emissions were strictly restricted as the result of an environmental regulation, the total value of output loss to the OECD countries as a whole would correspond to 3.7, 4.8 and 3.5% of the total OECD GDP for 1980, 1985 and 1990, respectively. © 2000 Academic Press.

Is environmental efficiency trade inducing or trade hindering?
(Elsevier, 2014) Doganay, S. M.; Sayek, S.; Taskin, F.
Global efforts to identify strategies for sustainable economic growth and development underline the need for understanding important links between environmental policies and international trade. In this paper, by constructing an environmental efficiency index for 111 countries from 1980 to 2009, we are able to empirically test for one such link. An improvement in the environmental efficiency index in terms of carbon dioxide emissions reflects a decrease in the cost of efforts to mitigate the environmental costs associated with growth. Countries that improve their environmental efficiency are found to experience strong international trade effects, both through increased exports and increased imports. While the positive link between efficiency improvements and exports is supportive of the Porter hypothesis, the positive link between efficiency improvements and imports is supportive of strong positive income effects on account of environmental efforts. These results, which are robust to alternative estimation strategies, lend strong support to global efforts to improve countries' environmental efficiencies. © 2014 Elsevier B.V.

A Kuznets curve in environmental efficiency: an application on OECD countries
(Springer Netherlands, 2000) Zaim, O.; Taskin, F.
The role of the environment is an important issue in policy making and the accurate assessment of the environmental conditions is vital. In this paper, using nonparametric techniques, an environmental efficiency index is developed for each of the OECD countries. These indexes allow one both to do cross section comparisons on the state of each country's production process in its treatment of undesirable outputs and also to trace each country's modification of their production processes overtime. Furthermore in this study we investigate the factors underlying societies' environmental concerns that eventually lead to changes in the environmental efficiency. The results provide further empirical evidence for the environmental Kuznets curve hypothesis.The role of the environment is an important issue in policy making and the accurate assessment of the environmental conditions is vital.

The indices facilitate cross-section comparisons on the status of each nation's production processes in its treatment of waste and pollutants. Modifications of production processes over time can also be tracked. Factors underlying societal environmental concerns that eventually result in changes in environmental efficiency are also analyzed, and results provide additional empirical evidence for the environmental Kuznets curve hypothesis.
