    A comparative analysis of the relationship between innovation and transport sector carbon emissions in developed and developing Mediterranean countries
    (Springer Heidelberg, 2021) Demircan Cakar, Nigar; Gedikli, Ayfer; Erdogan, Seyfettin; Yildirim, Durmus Cagri
    Innovation technologies have been recognized as an efficient solution to alleviate carbon emissions stem from the transport sector. The aim of this study is to investigate the impact of innovation on carbon emissions stemming from the transportation sector in Mediterranean countries. Based on the available data, Albania, Algeria, Bosnia and Herzegovina, Croatia, Egypt, Morocco, Tunisia, and Turkey are selected as the 8 developing countries; and Cyprus, France, Greece, Israel, Italy, and Spain are selected as the 6 developed countries and included in the analysis. Due to data constraints, the analysis period has been determined as 1997-2017 for the developing Mediterranean countries and 2003-2017 for the developed Mediterranean countries. After determining the long-term relationship with the panel co-integration method, we obtained the long-term coefficients with PMG and DFE methods. The empirical test results indicated that the increments in the level of innovation in developing countries have a positive impact on carbon emissions due to transportation if the innovation results from an increase in patents. An increase in the level of innovation in developed countries has a positive impact on carbon emissions due to transportation if the innovation results from an increase in trademark. As a result, innovation level has a positive effect on carbon emissions due to transportation, and this effect is stronger for developed countries.

    Exploring the nexus between human capital and environmental degradation: The case of EU countries
    (Academic Press Ltd- Elsevier Science Ltd, 2021) Cakar, Nigar Demircan; Gedikli, Ayfer; Erdogan, Seyfettin; Yildirim, Durmus Cagri
    Human capital investments have a vital role in economic growth. Therefore the effects of human capital on the environment should be analyzed for sustainable economic growth. This paper contributes to the debate on the nexus between human capital and environmental degradation. Based on 21 EU countries' panel data over the period 1994-2018, this study aims to analyze the relationship between human capital and environmental pollution in different financial development levels. We employed the panel smooth transition regression model (PSTR) to assess the nexus between the variables. According to the estimation results, human capital decreases carbon emissions in the low growth regime whereas increases in the high growth regime. Besides, human capital increases carbon emissions in both low regimes of financial development and human capital, and decreases in high regimes. The analysis indicated that as human capital improves, there will be more innovation to protect the environment, and thus there is less environmental degradation.
