    The Relationship Between Energy Consumption and Economic Growth: Evidence From Different Income Country Groups
    (Econjournals, 2017) Yaşar, N.
    This study analyses the relationship between energy consumption and economic growth for 119 countries during the period of 1970-2015, classified into four groups regarding to the World Bank income ranking. The main motivation of this study is to analyze whether the causal relationship differs between different income groups of countries. For this purpose, panel auto regressive distributed lag boundary approach and Granger causality test were used. The results of the study indicate that the causal relationship between energy use and economic growth differs depending on which income group country belongs to. We conclude that the feedback hypothesis is supported for upper-middle income group in the long run and high-income group, while conservation hypothesis is supported for upper-middle income group in the short run and lower-middle income group in the long run. Finally, neutrality hypothesis is supported for low and lower middle-income groups in the short run. © 2017, Econjournals. All rights reserved.

    The Relationship Between Foreign Direct Investment and Co 2 Emissions Across a Panel of Countries
    (Springer International Publishing, 2018) Yaşar, N.; Telatar, M.E.
    This paper analyses the relationship between foreign direct investment inflows and pollution emissions for 139 countries during the period of 1970-2015 and the countries are classified into four groups regarding to the World Bank income ranking. The main motivation of this study is to analyse, whether the causal relationship differs between different income groups. For this purpose, panel ARDL (Auto Regressive Distributed Lag) boundary approach and Granger causality test are used. The results of the study indicate that the causal relationship between FDI (Foreign Direct Investment) and CO 2 emissions differs depending on which income group country belongs to. We conclude that, while there is not statistically significant short-run causality relationship running from FDI to CO 2 emission for high income, upper middle income and low income group countries, the pollution haven hypothesis is supported for lower middle income group countries. © Springer International Publishing AG, part of Springer Nature 2018.

    A Relationship Marketing Strategy in Brand Communication: Influencer Marketing Strategy
    (IGI Global, 2019) Dursun, T.; Ôzsaçmaci, B.
    Influencer marketing increases brand awareness by generating appropriate content to attract the attention of consumers in a virtual environment in accordance with the brand texture. This chapter explores research to determine importance of influencer marketing in the brand communication area, which is based on relationship marketing. Authors mainly focus on influencer marketing and its connection with relationship marketing. They describe the constituent parts of the topics and illustrate them with the case studies and statistical facts. The authors strongly claim influencer marketing shares similar variables with relationship marketing and their basic keywords are related. © 2020 by IGI Global.

    Stationarity Properties of Renewable Energy Consumption in the Commonwealth of Independent States
    (Econjournals, 2020) Yasar, N.
    This study investigates the stochastic properties of renewable energy consumption series across 11 Commonwealth of Independent States countries through the period of 1990-2015. For this purpose, along with traditional stationarity analysis recently improved unit root techniques which allows for nonlinear adjustments in the data generating process are used in this paper. Based on our findings we may conclude that, consideration of nonlinearity in regression process causes to more frequent non rejection of the null hypothesis of stationarity. It implies that ignoring possible nonlinearities in time series regression process may lead to some misleading results. Hereby, fluctuations in global energy supply and trade systems influence renewable energy consumption in nonlinear pattern and policy-makers should take it into consideration in terms of proper energy policy implication. © 2019, Econjournals.

    The Stochastic Futures of the Natural Gas Prices: Russian Federation in Caspian Region
    (2014) Yaşar Başkaraağaç, Nermin
    This study examines the convergence hypothesis of natural gas price series of Russian Federation and USA using both linear and nonlinear time series techniques Russian Federation and USA during the period of 1991-2011. Although the linear Augmented Dickey Fuller (ADF), Philips Perron (PP), test provide evidence of the existence of a unit root, which means that the series are nonstationary, KPSS test result support the null hypothesis of existence of the stationary series. A nonlinear test as an alternative approach to investigate whether there are nonlinearities in the series is also taken into consideration. KSS, the nonlinear testing procedure provide some supportive evidence of a nonlinear price convergence among the Russian Federation and USA.
