    Are fluctuations in coal consumption per capita temporary? Evidence from developed and developing economies
    (Pergamon-elsevıer scıence ltd, 2014) Shahbaz, Muhammad; Tiwari, Aviral Kumar; Jam, Farooq Ahmed; Öztürk, İlhan
    This paper investigates the unit root properties of coal consumption per capita for the 47 developed and developing countries for 1965-2010 period. To examine the stationary properties of coal consumption per capita, Lagrange multiplier (LM) unit root test with one break and two breaks Crash model has been utilized. According to empirical results, the coal consumption is stationary in almost all the countries analyzed. Thus, if the coal consumption is mean (or trend) reverting, then it follows that the series will return to its mean value (or trend path) and it might be possible to forecast future movements in the coal consumption based on past behaviors of the series. For the policy makers, it is not necessary to pay attention to coal consumption excepting for Indian and Italian. However, for the researchers it is important to take into account the stationarity property of coal consumption and also structural breaks (should be modeled) in their future studies.

    Are fluctuations in electricity consumption per capita transitory? Evidence from developed and developing economies
    (PERGAMON-ELSEVIER SCIENCE LTD, 2013) Shahbaz, Muhammad; Tiwari, Aviral Kumar; Öztürk, İlhan; Farooq, Abdul
    This paper investigates the unit root properties of electricity consumption per capita of 67 developed and developing countries for the period 1971-2010. To examine the stationary properties of electricity consumption per capita, we have adopted Lee and Strazicich (2003,2004) test of unit root that allows us to test for at most two endogenous breaks and uses the Lagrange Multiplier (LM) test statistics. Results show that 65 country series reject the unit root null hypothesis except for 2 country series. Thus, our empirical findings provide significant evidence that electricity consumption per capita is stationary in almost all countries considered. The stationarity of electricity consumption per capita indicates that it should be possible for the series to forecast future movements in the energy consumption based on the past behaviors of the series.

    Tourism, energy consumption and climate change in OECD countries
    (2013) Tiwari, Aviral Kumar; Öztürk, İlhan; Aruna, M.
    The study analyzed dynamics of the relationship between tourism, energy consumption, and climate change for 25 OECD countries during 1995-2005. For the analysis, Panel VAR (PVAR) model was used. Results of panel unit root-tests show that tourism is nonstationary in the level form but stationary in first difference form and energy consumption and climate change are stationary variables in the level form. Analysis of bivariate model shows that results are sensitive with change in the measurement of the tourism variable, change in order of variable and inclusion of the third variable. However, results of our trivariate model are found to be insensitive with either the change in the measurement of our tourism variable or change in the ordering of the variables. Our results of IRFs shows that response of tourism in one SD shock in climate change and energy consumption and response of climate change emissions to tourism is marginally positive. Further, we find that response of climate change in one SD shock in energy consumption and response of energy consumption in one SD shock in tourism and climate change is zero.
