Analyzing long lasting effects of environmental policies: Evidence from low, middle and high income economies
(ELSEVIER SCIENCE BV, PO BOX 211, 1000 AE AMSTERDAM, NETHERLANDS, 01.01.2019) Ozcan, Burcu; Ulucak, Recep; Dugan, Eyup; 0000-0001-8800-8880; 0000-0001-9938-0063; 0000-0003-0476-5177; AGÜ, Yönetim Bilimleri Fakültesi, Ekonomi Bölümü
This study investigates whether or not environmental policies have long lasting effects by analyzing stochastic properties of ecological footprint that recently attracts a great attention and is accepted as a broader measure of the environmental degradation in the literature. To this end, countries are classified by income groups and the panel KSS unit root test alongside the SPSM procedure are utilized based on the annual data from 1961 to 2013. The empirical results show that ecological footprint has stationary process for all high-income countries and for about the half of the low-income and upper-middle income economies, whereas non-stationarity is verified for the lower-middle income economies. Crucial policy implications are further discussed.
Using Nudges to Reduce Cheating in Exams: A Randomized-field Experiment
(Duvar, 11.10.2023) Burak Kağan Demirtaş; 0000-0001-9477-8128; AGÜ, Yönetim Bilimleri Fakültesi, Ekonomi Bölümü
Cheating behavior is a significant problem within the education system. This study aims to mitigate cheating behavior through the implementation of various nudges. A randomized field experiment was conducted at a Turkish state university, involving a control group and three treatment groups. Students in the treatment groups were exposed to different nudges. The first treatment involved kindly discouraging cheating, while the second prompted students to consider whether cheating was fair to their friends and society. The third treatment asked a question to encourage reflection on the negative consequences of cheating. The results indicate that merely instructing students not to cheat had no impact on their behavior. However, the prevalence of cheating was lowerwhen students were encouraged to recognize the unfairness of cheating to their peers and society. Furthermore, cheating was reduced in the third treatment, although the nudge's effect was less pronounced than in the second treatmentin average however the difference is not statistically significant.
TOPLUMSAL İNŞACI YAKLAŞIM VE AVRUPA BÜTÜNLEŞMESİNİN AÇIKLANMASINA KATKILARI
(ANKARA UNIV EUROPEAN UNION RESEARCH CENTRE, 2015) Büyüktanır, Derya; AGÜ, Yönetim Bilimleri Fakültesi, Ekonomi Bölümü; Büyüktanır, Derya
Uluslararası ilişkiler disiplini içinde 1980’ler sonrasında ortaya çıkan toplumsal inşacı yaklaşım, bir önermeler topluluğu olarak günümüzde kendine önemli bir yer edinmiştir. İnşacılık, öznelerarası anlam, normlar, kurallar, kurumlar, söylem ve iletişimsel eylem gibi sosyal ontolojilere odaklanmakta ve bu nitelemelerin, epistomolojik konulara indirgenmesini engellemektedir. Bu yönleriyle inşacı yaklaşım, Avrupa Entegrasyonu üzerine yapılan araştırmalarda bir çıkış noktası oluşturmaktadır. Çünkü inşacı yaklaşım, Avrupa bütünleşmesinin şimdiki duruma nasıl ve neden geldiği gibi soruların cevaplanmasında, özneler arasındaki etkileşimin ve toplumsal etkilerin analizi büyük ölçüde yardımcı olmaktadır. Avrupa bütünleşmesini açıklayan bütünleşme kuramları yerine bu süreci, toplumsal inşacı yaklaşımla açıklamak, daha önce incelenmeyen birçok konunun rasyonel bakış açısından tamamen ayrılmadan ele alınmasını sağlamaktadır.
Revisiting the Relationship Between Natural Gas Consumption and Economic Growth in Turkey
(TAYLOR & FRANCIS INC, 2015) Dogan, Eyup; 0000-0003-0476-5177; AGÜ, Yönetim Bilimleri Fakültesi, Ekonomi Bölümü; Dogan, Eyup
The objective of this study is to re-analyze the relationship between natural gas consumption (NGC) and economic growth (GR) for Turkey in a multivariate framework by including capital and labor as additional variables because several papers suggest that a bivariate model can suffer from omitted-variables bias. As compared to the findings of Isik (2010), who previously investigated the short-and long-run relationships between GR and NGC using a bivariate model, we find that the magnitude of the coefficient estimate of NGC become substantially smaller in the long-run and the sign of short-run estimate of NGC shift to negative after accounting for capital and labor as well. In addition to that covered by Isik (2010), we investigate the direction of causality between GR and NGC using the vector error correction model Granger causality approach, and reveal the evidence of feedback hypothesis for Turkey.
Social media utilization of tourists for travel-related purposes
(EMERALD GROUP PUBLISHING LTD, 2015) Oz, Mustafa; AGÜ, Yönetim Bilimleri Fakültesi, İşletme Bölümü; Oz, Mustafa
Purpose - The aim of this study is to determine social media use by consumers for travel-related purposes. Design/methodology/approach - A quantitative study was conducted after reviewing the related literature. The primary data were collected by means of an online questionnaire, and the results were analyzed using a statistical package program. Findings - The respondents use social media intensively both in their daily lives (> 96 per cent) and in travel-related activities (95 per cent). In addition to the detailed analyses of their usage, a model was developed to identify the factors behind social media use for travel-related purposes. Research limitations/implications - As a result of an online questionnaire method, only consumers having an Internet access could respond to the survey. Additionally, the sample was not random, and the respondents were selected only from Turkey. Consequently, the study may suffer from a generalization problem, especially for markets with major different cultural characteristics. Practical implications - The findings of the study may assist academics and practitioners to better understand social media and Web 2.0 technologies and their effects on consumers. Originality/value - One of the dominant trends affecting consumer behavior and tourism marketing in recent years is the use of social media. It is critical to understand such developments and their effects on consumer behavior that may impact on the distribution and accessibility of travel-related information
The relationship between economic growth and electricity consumption from renewable and non-renewable sources: A study of Turkey
(ELSEVIER, 2015) Dogan, Eyup; 0000-0003-0476-5177; AGÜ, Yönetim Bilimleri Fakültesi, Ekonomi Bölümü; Dogan, Eyup
The main objective of this study is to analyze the short and long run estimates as well as the causality relationships between economic growth (GR), electricity consumption from renewable sources (RELC) and electricity consumption from non-renewable sources (NRELC) for Turkey in a multivariate model wherein capital (K) and labor (L) are included as additional variables. Using the autoregressive distributed lag (ARDL) approach to cointegration, the Johansen cointegration test and the Gregory-Hansen cointegration test with structural break, we show that GR, RELC, NRELC, K and L are cointegrated. Although NRELC has a long run positive effect on GR, the long run estimate of RELC is negative but insignificant at 5% level of significance. The Granger causality test based on the vector error correction model reveals the evidence of neutrality hypothesis between RELC and GR, and between NRELC and GR in Turkey in the short run. In addition, the Granger causality runs from RELC, NRELC, K and L to GR as well as from GR, RELC, K and L to NRELC in the long run, which supports the existence of growth hypothesis between RELC and GR, and feedback hypothesis between NRELC and GR in the long run. It is advised that policy makers in the Turkish government should continue to reduce the share of electricity consumption from renewable sources and encourage the usage of electricity from non-renewable sources to have sustainable long run growth rates. It is also essential to promote the investment projects to increase the efficiency of electricity generation from non-renewable sources.
CO2 emissions, real output, energy consumption, trade, urbanization and financial development: testing the EKC hypothesis for the USA
(SPRINGER HEIDELBERGTIERGARTENSTRASSE 17, D-69121 HEIDELBERG, GERMANY, 2016) Dogan, Eyup; Turkekul, Berna; 0000-0003-0476-5177; AGÜ, Yönetim Bilimleri Fakültesi, Ekonomi Bölümü; Dogan, Eyup
This study aims to investigate the relationship between carbon dioxide (CO2) emissions, energy consumption, real output (GDP), the square of real output (GDP(2)), trade openness, urbanization, and financial development in the USA for the period 1960-2010. The bounds testing for cointegration indicates that the analyzed variables are cointegrated. In the long run, energy consumption and urbanization increase environmental degradation while financial development has no effect on it, and trade leads to environmental improvements. In addition, this study does not support the validity of the environmental Kuznets curve (EKC) hypothesis for the USA because real output leads to environmental improvements while GDP(2) increases the levels of gas emissions. The results from the Granger causality test show that there is bidirectional causality between CO2 and GDP, CO2 and energy consumption, CO2 and urbanization, GDP and urbanization, and GDP and trade openness while no causality is determined between CO2 and trade openness, and gas emissions and financial development. In addition, we have enough evidence to support one-way causality running from GDP to energy consumption, from financial development to output, and from urbanization to financial development. In light of the long-run estimates and the Granger causality analysis, the US government should take into account the importance of trade openness, urbanization, and financial development in controlling for the levels of GDP and pollution. Moreover, it should be noted that the development of efficient energy policies likely contributes to lower CO2 emissions without harming real output.
The impact of trade openness on global carbon dioxide emissions: Evidence from the top ten emitters among developing countries
(ELSEVIERRADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS, 2016) Ertugrul, Hasan Murat; Cetin, Murat; Seker, Fahri; Dogan, Eyup; AGÜ, Yönetim Bilimleri Fakültesi, Ekonomi Bölümü; Dogan, Eyup
This study aims to analyze the relationship between carbon dioxide (CO2) emissions, trade openness, real income and energy consumption in the top ten CO2 emitters among the developing countries; namely China, India, South Korea, Brazil, Mexico, Indonesia, South Africa, Turkey, Thailand and Malaysia over the period of 1971-2011. In addition, the possible presence of the EKC hypothesis is investigated for the analyzed countries. The Zivot-Andrews unit root test with structural break, the bounds testing for cointegration in the presence of structural break and the VECM Granger causality method are employed. The empirical results indicate that (i) the analyzed variables are co-integrated for Thailand, Turkey, India, Brazil, China, Indonesia and Korea, (ii) real income, energy consumption and trade openness are the main determinants of carbon emissions in the long run, (iii) there exists a number of causal relations between the analyzed variables, (iv) the EKC hypothesis is validated for Turkey, India, China and Korea. Robust policy implications can be derived from this study since the estimated models pass several diagnostic and stability tests. (C) 2016 Elsevier Ltd. All rights reserved.
Analyzing the linkage between renewable and non-renewable energy consumption and economic growth by considering structural break in time-series data
(PERGAMON-ELSEVIER SCIENCE LTDTHE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, ENGLAND, 2016) Dogan, Eyup; 0000-0003-0476-5177; AGÜ, Yönetim Bilimleri Fakültesi, Ekonomi Bölümü; Dogan, Eyup
Even though a number of studies investigate the energy-growth nexus, only a small number of the existing studies use estimation techniques with structural break. Furthermore, majority of the existing studies use aggregate energy consumption and thus fail to identify the effects of energy consumption by sources on economic growth. By taking into account the importance of structural break, this study analyzes the short run and the long run estimates as well as the causality relationship between economic growth, renewable and non-renewable energy consumption for Turkey in a multivariate model wherein capital and labor are included as additional variables. By including additional variables into the model, we also attempt to handle omitted-variable bias problem. This study finds that renewable energy consumption has an insignificant impact on economic growth while non-renewable energy consumption has a significant positive effect on it. The coefficients on capital and labor are statistically significant. Furthermore, we have enough evidence to support conservation hypothesis and feedback hypothesis between renewable energy consumption and economic growth in the short run and the long run, respectively, and feedback hypothesis between non-renewable energy consumption and economic growth both in the short run and the long run. Several policy implications are further discussed. (C) 2016 Elsevier Ltd. All rights reserved.
The influence of biomass energy consumption on CO2 emissions: a wavelet coherence approach
(SPRINGER HEIDELBERGTIERGARTENSTRASSE 17, D-69121 HEIDELBERG, GERMANY, 2016) Bilgili, Faik; Ozturk, Ilhan; Kocak, Emrah; Bulut, Umit; Pamuk, Yalcin; Mugaloglu, Erhan; Baglitas, Hayriye H.; AGÜ, Yönetim Bilimleri Fakültesi, Ekonomi Bölümü; Mugaloglu, Erhan
In terms of today, one may argue, throughout observations from energy literature papers, that (i) one of the main contributors of the global warming is carbon dioxide emissions, (ii) the fossil fuel energy usage greatly contributes to the carbon dioxide emissions, and (iii) the simulations from energy models attract the attention of policy makers to renewable energy as alternative energy source to mitigate the carbon dioxide emissions. Although there appears to be intensive renewable energy works in the related literature regarding renewables' efficiency/impact on environmental quality, a researcher might still need to follow further studies to review the significance of renewables in the environment since (i) the existing seminal papers employ time series models and/or panel data models or some other statistical observation to detect the role of renewables in the environment and (ii) existing papers consider mostly aggregated renewable energy source rather than examining the major component(s) of aggregated renewables. This paper attempted to examine clearly the impact of biomass on carbon dioxide emissions in detail through time series and frequency analyses. Hence, the paper follows wavelet coherence analyses. The data covers the US monthly observations ranging from 1984:1 to 2015 for the variables of total energy carbon dioxide emissions, biomass energy consumption, coal consumption, petroleum consumption, and natural gas consumption. The paper thus, throughout wavelet coherence and wavelet partial coherence analyses, observes frequency properties as well as time series properties of relevant variables to reveal the possible significant influence of biomass usage on the emissions in the USA in both the short-term and the long-term cycles. The paper also reveals, finally, that the biomass consumption mitigates CO2 emissions in the long run cycles after the year 2005 in the USA.
The influence of real output, renewable and non-renewable energy, trade and financial development on carbon emissions in the top renewable energy countries
(PERGAMON-ELSEVIER SCIENCE LTDTHE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, ENGLAND, 2016) Dogan, Eyup; Seker, Fahri; 0000-0003-0476-5177; AGÜ, Yönetim Bilimleri Fakültesi, Ekonomi Bölümü; Dogan, Eyup
Due to tremendous increase in the level of carbon dioxide (CO2) emissions in the last several decades, a number of studies in the energy-growth-environment literature have attempted to identify the determinants of CO2 emissions. A major criticism related to the existing studies, we realize, is the selection of panel estimation techniques. Almost all studies use panel methods that ignore the issue of cross-sectional dependence even though countries in the panel are most likely heterogeneous and cross-sectionally dependent In addition, the majority of existing studies use aggregate energy consumption, and thus fail to identify the impacts of energy consumption by sources on the environment In order to fulfill the mentioned gaps in the literature, this empirical study analyzes the influence of the real income, renewable energy consumption, non-renewable energy consumption, trade openness and financial development on CO2 emissions in the EKC model for the top countries listed in the Renewable Energy Country Attractiveness Index by employing heterogeneous panel estimation techniques with cross-section dependence. We find that the analyzed variables become stationary at their first-differences by using the CADF and the CIPS unit root tests, and the analyzed variables are cointegrated by employing the LM bootstrap cointegration test By using the FMOLS and the DOLS, we also find that increases in renewable energy consumption, trade openness and financial development decrease carbon emissions while increases in non-renewable energy consumption contribute to the level of emissions, and the EKC hypothesis is supported for the top renewable energy countries.

Are shocks to electricity consumption transitory or permanent? Sub-national evidence from Turkey
(ELSEVIER SCI LTDTHE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, OXON, ENGLAND, 2016) Dogan, Eyup; 0000-0003-0476-5177; AGÜ, Yönetim Bilimleri Fakültesi, Ekonomi Bölümü; Dogan, Eyup
This is the first study that aims to investigate policy shocks to energy consumption in terms of unit root properties by sector. More precisely, we analyze the stationarity of electricity consumption for 12 regions of Turkey by four sectors in addition to total electricity consumption by region (for a total of 60 cases). We find that 48 cases are non-stationary and 12 cases are stationary. Thus, policies to decrease or stimulate the use of electricity have permanent effects on electricity consumption in 80% of the cases and transitory effects in the rest. Findings and policy implications are further discussed. (C) 2016 Elsevier Ltd. All rights reserved.
Exploring the relationship between agricultural electricity consumption and output: New evidence from Turkish regional data
(ELSEVIER SCI LTDTHE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, OXON, ENGLAND, 2016) Dogan, Eyup; Sebri, Maamar; Turkekul, Berna; 0000-0003-0476-5177; AGÜ, Yönetim Bilimleri Fakültesi, Ekonomi Bölümü; Dogan, Eyup
This study investigates the relationship between agricultural electricity consumption and agricultural output for a panel of 12 regions of Turkey for the period 1995-2013. In order to reveal the possible heterogeneity between regions, empirical analyses are conducted for the whole panel data and two subgroups within the panel data; namely, coastal regions and non-coastal regions. The results from several panel unit root tests indicate that electricity consumption and output are stationary process at their levels for overall panel and the two specific groups. By using the OLS with regional fixed effects, this study finds that coefficient estimate of electricity consumption on output is statistically significant and positive for overall regions, coastal regions and non-coastal regions. In addition, the results from the Dumitrescu-Hurlin Granger causality test show that there is unidirectional causality running from agricultural output to electricity consumption for non-coastal regions, and there is bidirectional causality between agricultural electricity consumption and output for overall panel and coastal regions. Findings and policy implications are further discussed. (C) 2016 Elsevier Ltd. All rights reserved.
How do firms benefit from customer complaints?
(ELSEVIER SCIENCE INCSTE 800, 230 PARK AVE, NEW YORK, NY 10169, 2016) Yilmaz, Cengiz; Varnali, Kaan; Kasnakoglu, Berna Tari; AGÜ, Yönetim Bilimleri Fakültesi, Ekonomi Bölümü; Yilmaz, Cengiz
The study explores the effects of two sets of factors relating to complaint management on firm performance, namely, (1)customer response factors and (2) organizational learning factors, thereby integrating organizational learning into the conceptualization of complaint management Symmetric testing using hierarchical regression analysis of data obtained from complainants and firm managers revealed the joint effects of the two main paths on firm performance, independently from one another. Learning from complaints is shown to influence both short- and long-term firm-level performance measures positively. However, contrary to expectations, complainants' and managers' perceptions of fairness in the complaint handling processes of firms are found to (1) be nonrelated to short-term firm performances and (2) influence long-term performance expectancies negatively. Asymmetric analyses involving contrarian cases and further utilizing the fuzzy-set qualitative comparative analysis (fsQCA) disclosed distinct sets of antecedents that are sufficient for explaining short- and long-term firm performance.

Determinants of CO2 emissions in the European Union: The role of renewable and non-renewable energy
(PERGAMON-ELSEVIER SCIENCE LTDTHE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, ENGLAND, 2016) Dogan, Eyup; Seker, Fahri; 0000-0003-0476-5177; AGÜ, Yönetim Bilimleri Fakültesi, Ekonomi Bölümü; Dogan, Eyup
A number of studies in the environment-energy-growth literature aim to pin down the determinants of carbon dioxide (CO2) emissions as a result of large increases in CO2 emissions over the last few decades. One criticism related to the existing literature is the selection of data. The majority of studies use aggregate energy consumption. The other criticism is the selection of panel estimation techniques. Almost all studies use panel methods that ignore cross-sectional dependence. To fulfill the mentioned gaps in the literature, this empirical study aims to investigate the impacts of renewable and non-renewable energy, real income and trade openness on CO2 emissions in the Environmental Kuznets Curve (EKC) model for the European Union over the period 1980-2012 by employing panel estimation techniques robust to cross-sectional dependence. By using the dynamic ordinary least squares estimator, we show that renewable energy and trade mitigate carbon emissions while non-renewable energy increases CO2 emissions, and the EKC hypothesis is supported. The Dumitrescu-Hurlin non-causality approach indicates that there is bidirectional causality between renewable energy and carbon emissions, and unidirectional causality running from real income to carbon emissions, from CO2 emissions to non-renewable energy, and from trade openness to CO2 emissions.

An investigation on the determinants of carbon emissions for OECD countries: empirical evidence from panel models robust to heterogeneity and cross-sectional dependence
(SPRINGER HEIDELBERGTIERGARTENSTRASSE 17, D-69121 HEIDELBERG, GERMANY, 2016) Dogan, Eyup; Seker, Fahri; 0000-0003-0476-5177; AGÜ, Yönetim Bilimleri Fakültesi, Ekonomi Bölümü; Dogan, Eyup
This empirical study analyzes the impacts of real income, energy consumption, financial development and trade openness on CO2 emissions for the OECD countries in the Environmental Kuznets Curve (EKC) model by using panel econometric approaches that consider issues of heterogeneity and cross-sectional dependence. Results from the Pesaran CD test, the Pesaran-Yamagata's homogeneity test, the CADF and the CIPS unit root tests, the LM bootstrap cointegration test, the DSUR estimator, and the Emirmahmutoglu-Kose Granger causality test indicate that (i) the panel time-series data are heterogeneous and cross-sectionally dependent; (ii) CO2 emissions, real income, the quadratic income, energy consumption, financial development and openness are integrated of order one; (iii) the analyzed data are cointegrated; (iv) the EKC hypothesis is validated for the OECD countries; (v) increases in openness and financial development mitigate the level of emissions whereas energy consumption contributes to carbon emissions; (vi) a variety of Granger causal relationship is detected among the analyzed variables; and (vii) empirical results and policy recommendations are accurate and efficient since panel econometric models used in this study account for heterogeneity and cross-sectional dependence in their estimation procedures.
CO2 Emissions, Real GDP, Renewable Energy and Tourism: Evidence from Panel of the Most-Visited Countries
(CESKY STATISTICAL OFFICENA PADESATEM 81, PRAGUE 10, 10082, CZECH REPUBLIC, 2017) Dogan, Eyup; AGÜ, Yönetim Bilimleri Fakültesi, Ekonomi Bölümü
Previous studies on the energy-environment-growth literature overlook the investigation of the most-visited countries. Since these countries do not only belong to the largest economies and the top carbon dioxide (CO2) emitters in the world but are also listed in renewable energy country attractiveness index, this study analyzes the impacts of real GDP, renewable energy and tourism on the level of CO2 emissions for the top 10 most-visited countries. Applying several panel econometric approaches, we find out that renewable energy mitigates the pollution whereas real GDP and tourism contribute to the level of emissions. Thus, regulatory policies are necessary to increase the awareness of sustainable tourism. In addition, the use of renewable energy and the adoption of clean technologies in tourism sector as well as in producing goods and services play a significant role in CO2 mitigation.
Analyzing the effects of real income and biomass energy consumption on carbon dioxide (CO2) emissions: Empirical evidence from the panel of biomass-consuming countries
(PERGAMON-ELSEVIER SCIENCE LTDTHE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, ENGLAND, 2017) Dogan, Eyup; Inglesi-Lotz, Roula; 0000-0001-7509-4687; 0000-0003-0476-5177; AGÜ, Yönetim Bilimleri Fakültesi, Ekonomi Bölümü
Even though the energy-growth-environment literature put a lot of effort into investigating the impact on carbon dioxide (CO2) emissions of aggregate energy consumption, aggregate renewable energy consumption and aggregate non-renewable energy consumption, the importance of biomass energy consumption for the environment is not well covered. Besides, the existing studies do not reach a consensus on the validity of the Environmental Kuznets Curve (EKC) hypothesis. Therefore, this study fulfills the gaps in the literature by investigating the impact of biomass energy consumption on CO2 emissions in the EKC model for the panel of biomass-consuming countries. By using some control variables and applying econometric approaches that take into account heterogeneity and cross-sectional dependence across countries in the panel, we find that the EKC hypothesis is valid and biomass energy consumption decreases the level of CO2 emissions. These results are supportive of the international notion that investing in biomass energy infrastructure and biomass supply are an appropriate direction the energy policy makers can use in their efforts to reduce environmental degradation in the long-run.

The significance of renewable energy use for economic output and environmental protection: evidence from the Next 11 developing economies
(SPRINGER HEIDELBERGTIERGARTENSTRASSE 17, D-69121 HEIDELBERG, GERMANY, 2017) Paramati, Sudharshan Reddy; Sinha, Avik; Dogan, Eyup; 0000-0003-0476-5177; AGÜ, Yönetim Bilimleri Fakültesi, Ekonomi Bölümü
Increasing economic activities in developing economies raise demand for energy mainly sourced from conventional sources. The consumption of more conventional energy will have a significant negative impact on the environment. Therefore, attention of policy makers has recently shifted towards the promotion of renewable energy generation and uses across economic activities to ensure low carbon economy. Given the recent scenario, in this paper, we aim to examine the role of renewable energy consumption on the economic output and CO2 emissions of the next fastest developing economies of the world. The study employs several robust panel econometric models by using annual data from 1990 to 2012. Empirical findings confirm the significant long-run association among the variables. Similarly, results show that renewable energy consumption positively contributes to economic output and has an adverse effect on CO2 emissions. Given our findings, we suggest policy makers of those economies to initiate further effective policies to promote more renewable energy generation and uses across economic activities to ensure sustainable economic development.
Does corruption matter for the environment? Panel evidence from China
(WALTER DE GRUYTER GMBHGENTHINER STRASSE 13, D-10785 BERLIN, GERMANY, 2017) Liao, Xianchun; Dogan, Eyup; Baek, Jungho; AGÜ, Yönetim Bilimleri Fakültesi, Ekonomi Bölümü; Dogan, Eyup
This article examines the income-energy-SO2 emissions nexus by taking a corruption variable into account. To that end, the panel cointegration methods are applied to 29 Chinese provinces over 1999-2012. The authors 'empirical evidence shows that an increase in the number of anti-corruption cases tends to drive down SO2 emissions in China. It is also found that income growth appears to have a beneficial effect on decreasing SO2 emissions over the past two decades. Finally, energy consumption is found to increase SO2 emissions.
