Long-run effect of international trade on the environment: a Pool Mean Group analysis of ECOWAS countries, 1970-2010

This study employs the Pool Mean Group estimator proposed by Pesaran et al. (1999) to examine the long-run impact of international trade on the environment in a panel of 11 ECOWAS countries over the period 1970-2010. The main findings of the study suggest that international trade contribute to the degradation of the environment. The results for income give support to the environmental Kuznets curve hypothesis.
