    Assessing links between energy consumption, freight transport, and economic growth: evidence from dynamic simultaneous equation models
    (Sprınger Heıdelberg, 2018) Nasreen, Samia; Saidi, Samir; Öztürk, İlhan
    We investigate this study to examine the relationship between economic growth, freight transport, and energy consumption for 63 developing countries over the period of 1990-2016. In order to make the panel data analysis more homogeneous, we apply the income level of countries to divide the global panel into three sub-panels, namely, lower-middle income countries (LMIC), upper-middle income countries (UMIC), and high-income countries (HIC). Using the generalized method of moments (GMM), the results prove evidence of bidirectional causal relationship between economic growth and freight transport for all selected panels and between economic growth and energy consumption for the high- and upper-middle income panels. For the lower-middle income panel, the causality is unidirectional running from energy consumption to economic growth. Also, the results indicate that the relationship between freight transport and energy use is bidirectional for the high-income countries and unidirectional from freight transport to energy consumption for the upper-middle and lower-middle income countries. Empirical evidence demonstrates the importance of energy for economic activity and rejects the neo-classical assumption that energy is neutral for growth. An important policy recommendation is that there is need of advancements in vehicle technology which can reduce energy intensity from transport sector and improve the energy efficiency in transport activity which in turn allows a greater positive role of transport in global economic activity.

    Financial stability, energy consumption and environmental quality: Evidence from South Asian economies
    (PERGAMON-ELSEVIER SCIENCE LTD, 2017) Nasreen, Samia; Anwar, Sofia; Öztürk, İlhan
    A few studies are found on the relationship between financial instability, energy consumption and environmental quality in energy economics literature. The current study is an endeavor to fill this gap by investigating the relationship between financial stability, economic growth, energy consumption and carbon dioxide (CO2) emissions in South Asian countries over the period 1980-2012 using a multivariate framework. Bounds test for cointegration and Granger causality approach are employed for the empirical analysis. Estimated results suggest that all variables are non-stationary and cointegrated. The results show that financial stability improves environmental quality; while the increase in economic growth, energy consumption and population density are detrimental for environment quality in the long-run. The results also support the environmental Kuznets curve (EKC) hypothesis which assumes an inverted U-shaped path between income and environmental quality. Moreover, the study found the evidence of unidirectional causality running from financial stability to CO2 emissions in two countries i.e. Pakistan and Sri Lanka. The findings of this study open up new insight for policy makers to design a comprehensive financial, economic and energy supply policies to minimize the detrimental impact of environmental pollution.
