- ArticleYalnız künye2024The effects of financial development, trade and energy consumption on environmental degradation: Evidence from APEC countries
Balli, Esra; Çatik, Abdurrahman Nazif; Uğur, Mehmet Sedat; Sigeze, Ciler
This paper investigates the relationship among CO2 emissions, energy consumption, economic growth, financial development, and trade in APEC countries based on quarterly data from 1985:Q4 to 2020:Q4 utilizing the Method of Moments Quantile Regression (MMQR). The results demonstrate that both GDP and energy consumption have a positive and statistically significant effect on CO2 emissions. However, this effect diminishes as the conditional quantile of CO2 increases. Additionally, the study reveals that financial development has a positive and significant impact on CO2 emissions, with its influence increasing at higher quantiles. The MMQR estimates suggest that increasing trade openness has led to improvements in environmental quality. Based on these findings, it is recommended that APEC countries implement environmentally friendly policies to achieve sustainable economic development in the region. Hence, it is essential for financial development, energy consumption, and trade openness policies to align with strategies aimed at reducing environmental degradation.

This paper investigates the relationship between CO2 emissions, energy consumption, economic growth, and foreign direct investment for a sample of Asia-Pacific Economic Cooperation Countries (APEC) countries from 1981:Q1 to 2021:Q1 employing panel data methodology. We identify cross-sectional dependence and hence utilize the cross-sectional augmented Dickey-Fuller panel unit root test for appropriate estimation. The cointegration test developed by Westerlund (2008) reveals a long-run equilibrium between CO2 emissions, energy consumption, economic growth, and foreign direct investment. Long-run parameter estimates based on Common Correlated Effect Mean Group indicate that an increase in FDI inflows has a negative impact on air quality, supporting the pollution haven hypothesis. The cointegration test results also show that the impact of Gross Domestic Product (GDP) on CO2 emissions varies by country in the estimation sample. In contrast to the mixed evidence on the effects of other variables, the increase in energy consumption is positively and significantly affecting CO2 emissions in all APEC countries. Emirmahmutoglu and Kose Econ Model 28:870-876, (2011)’s panel causality test results show a bidirectional relationship between FDI and CO2 emissions in Japan. Furthermore, there is a bidirectional causal relationship between GDP and energy consumption in Australia, China, Japan, and Singapore. Overall, empirical evidence suggests that APEC countries should adhere to strict regulations and invest in environmental-friendly clean technologies to attract foreign direct investment.

Ugur, Mehmet Sedat; Çatık, Abdurrahman Nazif; Sigeze, Ciler; Balli, Esra
This paper investigates the time-varying effects of fossil fuel consumption on CO2 emissions in India utilizing the time-varying cointegration test, allowing for multivariate long-run time-varying cointegration parameter developed by Bierens and Martins (2010) and the time-varying vector autoregressive (TVP-VAR) model developed by Primiceri (2005). The long-run time-varying coefficients reveal that GDP has a positive and increasing impact on CO2 emissions over time. Moreover, results confirm the polluting effects of all fossil fuels. Besides, the TVP-VAR model findings also demonstrate that changes in income and fossil fuel consumption have a positive and significant impact on environmental degradation. Coal is found to be the most polluting fuel, followed by oil consumption. Furthermore, the time-varying responses show that increased natural gas consumption has the least influence when compared to other fossil fuels on CO2 emissions.

Balli, Esra; Nugent, Jeffrey B.; Coskun, Nuran; Sigeze, Ciler
Given that Turkey has recently committed itself for the first time to reducing its CO2 emissions in the interest of sustainable growth in not only Turkey but also the world as a whole, this paper examines the relationship between energy consumption, CO2 emissions, and economic growth in Turkey for the period 1960–2014. In view of the different findings concerning causality and the character of the relationships between these variables revealed in our review of past studies (in most cases using quite different methods), this paper utilizes several different but related methodological approaches for identifying causal relationships. These include both the Toda and Yamamoto (1995) approach, the Fourier Toda-Yamamoto for Cumulative Frequency approach developed by Nazlioglu et al. (2016), vector error correction model (VECM) methodology, and the asymmetric Granger causality test proposed by Hatemi-J (Empir Econ 43:447–456, Hatemi-j 2012). Our results show that, when we apply the popular Toda-Yamamoto model, causality in these relationships is not confirmed even among any of the relevant variables in Turkey. Yet, when the Fourier Toda-Yamamoto tests for cumulative frequency are employed, we find unidirectional causality running from GDP per capita to emissions of CO2 per capita. Moreover, when we utilize the VECM methodology, the results show that long-run causality exists from GDP per capita and energy to CO2 emissions. When we apply the asymmetric causality tests, the results provide even stronger evidence for a unidirectional causal relationship from GDP per capita to CO2 emissions. As a result, the latter sets of results, based on more realistic conditions, suggest very strongly that, if Turkey is to meet the objectives of its ambitious Climate Change Action Plan commitment to the United Nations to reduce its CO2 per capita emissions relative to its past trends by up to 21% over the coming 2021–2030 decade, it is going to get very serious about the best way to do this as soon as possible.

RDL Kalıcı Kaydıİncele - ArticleYalnız künye2019The relationship between tourism, CO 2 emissions and economic growth: a case of Mediterranean countries
Balli, Esra; Sigeze, Ciler; Manga, Muge; Birdir, Sevda; Birdir, Kemal
This study explores the impact of tourism on economic growth considering CO 2 emissions utilizing panel data techniques for a sample of Mediterranean countries. The cointegration tests reveal that there is a positive long-run equilibrium between tourism, CO 2 emissions and economic growth. This positive long-run relationship may suggest that tourism increases the level of CO 2 emissions and has a statistically significant impact on economic growth in Mediterranean countries. Emirmahmutoglu and Kose (2011. Testing for Granger causality in heterogeneous mixed panels. Economic Modelling, 28(3), 870–876.) test results reveal that the tourism-led growth hypothesis, which suggests that tourism contributes to economic growth, is valid for Egypt, Italy, and Spain. Additionally, there exists a bidirectional relationship between tourism and economic growth both in Morocco and Turkey.
