    Does military expenditure impact environmental sustainability in developed Mediterranean countries?
    (Springer Heidelberg, 2022) Erdoğan, Seyfettin; Gedikli, Ayfer; Çevik, Emrah İsmail; Öncü Mehmet Akif
    This study aims to examine the relationship between military expenditure and environmental sustainability in developed Mediterranean countries: Greece, France, Italy, and Spain. Sustainable economic growth is strictly related to energy consumption which leads to producing a higher level of carbon emissions. Besides, there may be a nexus between military expenditures and environmental pollution. This study focuses on developed Mediterranean countries since carbon emissions and greenhouse gas emissions are relatively high in these countries. Furthermore, France and Italy are the top countries in terms of total military spending. We investigate the relationship between military expenditure and carbon emissions using the Global Vector Autoregression model proposed by Pesaran et al. (J Bus Econ Stat 22 129:162, Pesaran et al., J Bus Econ Stat 22:129-162, 2004) and Dees et al. (J Appl Econ 22(1):38, Dees et al., J Appl Econ 22:1-38, 2007) between 1965 and 2019. The empirical findings indicated that the relationship between carbon emission and military expenditure should be taken into account from a global perspective for environmental sustainability, and an increase in the global military expenditure seems to be very harmful to the global environment. It can be concluded that country-based prevention cannot provide the desired solution in combating environmental pollution.

    Dynamic relationship between international tourism, economic growth and environmental pollution in the OECD countries: evidence from panel VAR model
    (Routledge Journals, Taylor & Francis Ltd, 2022) Gedikli, Ayfer; Erdoğan, Seyfettin; Çevik, Emrah İsmail; Çevik, Emre; Castanho, Rui Alexandre; Couto, Gualter
    The aim of this study is to examine the impact of international tourism on economic growth and carbon emissions by using the Panel VAR model in selected OECD countries. By using yearly data for the periods of 1995 and 2020, we examine the dynamic relationship between international tourism, economic growth, and carbon emissions using the Granger causality test and impulse responses analysis. Although we could not determine the presence of a causal link between the variables using the Granger causality test, impulse responses analysis confirmed that responses of carbon emissions and economic growth to an unexpected international tourism shock are positive and significant. On the other hand, impulse responses analysis results show that responses of carbon emissions and economic growth to unexpected international tourism are positive and significant. The empirical findings also indicated that the responses of carbon emissions to an unexpected international tourism shock are higher than the responses of economic growth to an unexpected international tourism shock and these findings indicate that the negative impact of international tourism on environmental quality is greater than its positive impact on economic growth. Policymakers should take actions and measures to reduce the impact of international tourism on environmental deterioration. Improvements and dissemination of eco-friendly technologies in all tourism activities may help to reduce the negative impact of international tourism on carbon emissions.

    Eco-friendly technologies, international tourism and carbon emissions: Evidence from the most visited countries
    (Elsevier Science Inc, 2022) Erdoğan, Seyfettin; Gedikli, Ayfer; Çevik, Emrah İsmail; Erdogan, Fatma
    The paper aims to examine the effects of international tourism on carbon emissions in the most visited countries using panel quantile regression for the periods 1995-2018. Since the primary source of carbon emissions from international tourism is transportation, we examine the moderating effect of eco-friendly innovations on the transportation sector for the relationship between international tourism and carbon emissions. Empirical results show that while international tourism led to an increase in carbon emissions between the fifth and ninth quantiles of carbon emissions, eco-friendly innovations for the transportation sector play an essential role in the effect of international tourism on carbon emissions. We find that the impact of improvements in eco-friendly technologies for transportation is significant on carbon emissions at all quantiles and that it eliminates the harmful effect of international tourism on environmental quality. These results are important for policy-makers to reduce carbon emissions from tourism because these countries have committed to reducing their carbon emissions according to the Paris Accord and the Sustainable Development Goals.

    Precious metals as safe-haven for clean energy stock investment: Evidence from nonparametric Granger causality in distribution test
    (Elsevier Sci Ltd, 2022) Erdoğan, Seyfettin; Gedikli, Ayfer; Çevik, Emrah İsmail; Erdogan, Fatma; Çevik, Emre
    The study aims to examine the connectedness between clean energy stocks and precious metals prices under the different market episodes. We employ the Granger causality-in-the distribution test proposed by Candelon and Tokpavi (2016) to investigate the presence of a causality relationship between the variables for the whole dis-tribution because the test has superior power even if the sample size is small. WilderHill Clean Energy Index is considered a benchmark for the clean energy stock market and gold, silver, platinum, and palladium prices are used for the precious metals. By using daily data from January 1, 2001, to December 12, 2021, we find that there is a unidirectional causal link running from the clean energy stock returns to the precious metal prices in the center and the left tail of the distribution. On the other hand, there is strong feedback between the variables in the right tail of the distribution. These results show that clean energy stock prices have an edge in affecting precious metal prices and precious metals cannot be used to hedge the downside risk of clean energy stock investments.
