ICT, total factor productivity, and carbon dioxide emissions in Tunisia

This paper examines the linkage between carbon dioxide (CO2) emissions, total factor productivity (TFP) as a measure of income, and information and communication technologies (ICT) in Tunisia from 1975 to 2014. To empirically investigate this relationship, the autoregressive distributed delay (ARDL) with the break point method is specified and estimated. The results demonstrate the rejection of the Environmental Kuznets Curve (EKC) hypothesis by obtaining a higher value of the long-term total factor productivity (TFP) coefficient compared the short term one. Moreover, the result indicates an insignificant impact of ICT on CO2 emissions as a measure of pollution. As a result, Tunisian policy makers should not only enhance their total factor productivity but also expand their information and communication technology.
