    Does ICT have symmetric or asymmetric effects on CO2 emissions? Evidence from selected Asian economies
    (Elsevier Sci Ltd, 2021) Usman, Ahmed; Ozturk, Ilhan; Ullah, Sana; Hassan, Ali
    Information and communication technology (ICT) has played an important role in the socio-economic development of human societies but, this development has come with some potential hazards to the environment. However, the experts are divided over this issue, some consider that ICT has exerted a favorable impact on environmental quality whereas; others think that ICT has posed serious threats to the environment. Hence, this study is another effort in exploring the impacts of ICT on CO2 emissions in 9 selected Asian economies which are the top contributors in polluting the environment in the Asian continent for the period of 1990-2018. All previous studies have one thing in common that the impact of ICT on CO2 emissions is symmetric. Whereas, in this study, we have not only relied on the symmetry assumption but also tested the asymmetric impact of ICT on CO2 emissions. The number of countries in which ICT significantly affects the CO2 releases has not changed much in our linear and non-linear models. However, the short-run impact asymmetry in the effects of increased and decreased use of ICT is approved in almost half of the countries, and in long run, these asymmetric impacts further strengthened and observed in more than half of the countries.

    The effect of ICT on energy consumption and economic growth in South Asian economies: An empirical analysis
    (Elsevier, 2021) Usman, Ahmed; Ozturk, Ilhan; Hassan, Ali; Zafar, Syeda Maria; Ullah, Sana
    This study contributes to the literature by analyzing the effects of information and communication technology (ICT) on economic performance and energy consumption of selected South Asian economies i.e. Bangladesh, India, Pakistan and Sri Lanka for the period of 1990-2018. For empirical analysis, we employed the bounds testing approach of cointegration and error correction modelling. The findings of the study confirm that, in the long-run, ICT significantly and positively contributed to the economic growth of India only. Similarly, India is the only country in South Asia that has achieved energy efficiency as a result of increased use of ICT. However, energy consumption proved to be an important determinant of GDP per capita in India and Pakistan. Also, GDP per capita has a positive and significant impact on energy consumption in both India and Pakistan. These results imply that South Asian economies try to follow their regional partner, India, in increasing the role of ICT in their economies, which on one side will boost their economic growth and on the other side will help them in achieving energy efficiency. Moreover, the energy conservation policy could prove detrimental to South Asian economies.
