Energy Consumption, Economic Growth, And Pollution In Selected Opec Countries: Testing The Environmental Kuznets Curve Hypothesis
This study attempted to investigate empirically the causal relationships among energy consumption, pollution, and economic growth for a panel of 8 selected OPEC countries over the period 1971-2008 inspiring panel data techniques. The findings showed that in the long-run equilibrium there is a bi-directional causality between energy consumption, and co2 emissions and a uni-directional causality running from economic growth to energy consumption, and pollution. In the short- run, the causality resulted also pointed out a uni-directional causality from economic growth to co2 emissions and from energy consumption to co2 emissions, and economic growth. Finally, since economic growth causes co2 emissions both in the short-run and in the long-run, we examined the functional form of the environmental Kuznets Curve. Our findings suggested a cubic (i.e. N-shaped) relationship between economic growth and co2 emissions for the countries under analysis. Therefore, panel data analyses did not confirm the inverted u-shaped Environmental Kuznets Curve hypothesis.
