    Environmental dimension of innovation: time series evidence from Turkey
    (Springer, 2020) Demir C.; Cergibozan R.; Ari A.
    The study aims to investigate whether domestic innovation reduces environmental degradation in Turkey. Since the empirical literature on this subject is relatively poor and there is no empirical evidence for the Turkish case, the study attempts to bring a new perspective to the existing literature. To do this, the study estimates the relationship between innovation and CO2 emissions over the period of 1971–2013, via the ARDL bounds test and threshold cointegration test. Empirical results obtained from the ARDL approach indicates that the relationship between CO2 emission level and number of domestic patents depicts an inverted U-shape curve for Turkey. Moreover, estimation results show that urbanization, income level and financial development have positive effects on CO2 emissions, while alternative energy sources and human capital negatively affect the emission level. Since the linear econometric methods may yield inconsistent and biased results in the presence of a nonlinear relationship, the threshold cointegration method is employed as a robustness check. The findings obtained from threshold cointegration confirm the existence of a nonlinear relationship between CO2 emissions and domestic innovation. This suggests that for early stages of economic development, increases in domestic innovation raise the CO2 emission level in Turkey, but after achieving a certain development level, increases in domestic innovation lead to decreases in CO2 emissions. Thus, either developing or developed countries can eventually reduce CO2 emission levels by concentrating on innovation. Policy makers and institutions dealing with environmental issues should certainly pay attention to innovation and technological progress to assure a sustainable growth path. © 2019, Springer Nature B.V.

    Does alternative energy usage converge across Oecd countries?
    (Elsevier Ltd, 2020) Demir C.; Cergibozan R.
    The purpose of this study is to examine whether there exists a significant convergence process in the share of alternative energy use across 28 OECD (The Organisation for Economic Co-operation and Development) countries over the 1971–2015 period. Since energy resources are scarce and the most widely used energy sources might be harmful to the environment, seeking the productive, efficient and cleaner energy types becomes more important. Moreover, international institutions and agreements on the environment strongly recommend using these types of energy sources. From this point of view, the study suggests that these efforts on increasing the share of alternative energy use will cause a convergence process between countries. The findings obtained from the difference- and system-GMM (generalized method of moments) estimations reveal that there is a statistically significant convergence process across OECD countries and it is also observed that the speed of convergence is even higher when the country-specific economic and social factors are controlled. © 2019 Elsevier Ltd

    Did Covid-19 Precautions and Lockdowns Cause Better Air Quality? Empirical Findings from Turkish Provinces
    (Cesky Statisticky Urad, 2022) Ari A.; Cergibozan R.; Demir C.
    The Covid-19 pandemic have dramatically affected the socio-economic structure in the world since governments put into action considerable precautions including lockdowns to reduce the speed of the contagion. Focusing on this point, we empirically investigate the environmental outcomes of the Covid-19 precautions and lockdowns in Turkey. The empirical analysis through the data obtained from different measurement stations indicate that the air pollution in the selected Turkish cities decreased due to the implemented precautions. The findings suggest that the Covid-19 might be an opportunity to rethink some economic and behavioral practices, as demonstrated by the reduction in the emission of air pollutants. © 2022.
