- MakaleAçık Erişim2025The technology, innovation, and income inequality nexus: an investigation on G7 countries
Çelik, Orkun; Sayın, Ferhan
This paper aims to explore the causality nexus among technology, innovation, and income inequality for G7 countries. For this aim, the bootstrap panel Granger approach is employed. The dataset covers the years between 1981 and 2015. Using two different Gini coefficients with pre-tax and post-tax income, the impact of income taxes on the nexus above is investigated. The results indicate that the bi-directional causality nexus is not detected in G7 countries except France. The signs of the nexus become different by countries. In this differentiation, income tax plays an important role. The novelty of this paper is to consider both the bi-directional causality and the effect of income tax in the technology, innovation, and income inequality nexus. It is thought that obtained findings may play a significant role in determining income distribution policies for policymakers.
- MakaleAçık Erişim2023Does ecological footprint in ECCAS and ECOWAS converge? Empirical evidence from a panel unit root test with sharp and smooth breaks
Çelik, Orkun; Adali, Zafer; Bari, Bilgin
The costs due to climate change have been increasing day by day. In addition to the risk of losing our planet’s natural assets due to the increasing destructiveness of climate-related natural disasters and extreme climate events, we are also faced with grave economic risks. For this reason, researchers have recently focused on environmental issues. Nevertheless, they generally have investigated developed countries and ignored developing and least developed countries such as African countries. The United Nations (2015) report highlights that African countries should be specially investigated. Hence, the paper analyzes whether the ecological footprint in the Economic Community of Central African States (ECCAS) and Economic Community of West African States (ECOWAS) converges for the period from 1961 to 2017. We employ Bahmani-Oskooee et al.’s (2014) panel unit root test with sharp and smooth breaks. The empirical findings demonstrate that the ecological footprint is stationary in ECCAS and ECOWAS. Stated in other words, the ecological footprint in these countries converges. Therefore, policymakers could implement similar policies to reduce the ecological footprint in these countries. This policy framework paves the way for an effective sustainable development.
- MakaleAçık Erişim2023Testing the Short, Medium, and Long-Term Effects of Shocks on Ecological Balance
Yilanci, Veli; Adali, Zafer; Çelik, Orkun; Bari, Bilgin
Ecological balance is an indicator of environmental degradation, which is computed as the difference between biocapacity and ecological footprint. In this study, we examine whether the effect of shocks on the ecological balance is permanent or temporary in the EU-15 countries, considering the period from 1961 to 2018. The application of unit root tests, with and without a Fourier function, indicates that the effects of shocks are temporary in only four countries. To reveal the persistence of shocks at different frequencies, that is, the short-, medium-, and long-run, we decomposed the ecological balance series by using the Discrete Wavelet Transform method. The unit root test results show that the effects of shocks are temporary in all countries in the short-run. However, the results also show that the shocks are temporary in nine countries in the medium-run and ten countries in the long-run. Thus, the implemented policies to balance ecology are not effective in the short-run but are effective in only six countries in the medium-term and in only five countries in the long-term. These findings demonstrate the importance of considering different frequencies when testing the effectiveness of empirically implemented policies. Regarding policy implications, this study suggests focusing on medium- and long-term environmental policies rather than short-term ones.
- MakaleYalnız künye2022How human capital affects labor income share at the sectoral level?: Evidence from the EU-13 countries and the UK
Çelik, Orkun
Purpose The author investigates the effects of human capital on labor income share in the 15 sectors of the European Union (EU)-13 countries and the United Kingdom (UK) over the period 2008-2015. Design/methodology/approach The author employs pooled ordinary least squares (OLS) estimation with panel data, using the EU KLEMS database. Findings The results show that when education level increases, labor income share increases and gender-based labor income share differentials decrease. Return to education is higher in qualitative sectors in contrast with the other sectors. Moreover, there are gender-based labor income share differentials at the sectoral level. These differentials are higher in nonqualitative sectors, while they are relatively lower in qualitative sectors. Research limitations/implications The biggest limitation of the study is that the data range cannot be expanded because of the database. The author is of opinion that the empirical findings will guide to policy makers in terms of wage setting. Originality/value The expected contribution of this study to the literature is to investigate the effect of human capital on labor income share at the sectoral level for the EU-13 countries and the UK. As far as the author knows, there is no study which investigates this topic at the sectoral level such a comprehensive, in the literature.

Çelik, Orkun; Karadağ, Metin
We aim to investigate the effect of Single Market Programme on the spatial interaction of labour income share amongst the EU countries. Spatial panel data analysis is used for the aim of the study. The dataset is obtained from AMECO and WDI databases and covers the time period of 1960–2017. The results show that sign of spatial interaction between these countries in term of the labour income share has turned from positive to negative after the Single Market Programme. In other words, the Single Market Programme has induced to decrease the labour income share by negatively affecting the spatial interaction between these countries. In addition, we find that although the negative impacts of capital-output ratio and trade openness on the labour income share decrease, the negative impact of total factor productivity increases after the Single Market Programme. The results of robustness check also confirm our empirical findings.
- MakaleYalnız künye2021Causality linkages between income inequality and financial globalization for G7 countries
Çelik, Orkun
The main aim of this study is to evaluate the causality linkages between income inequality and financial glo- balization for G7 countries over the period 1970-2015. The bootstrap panel Granger causality analysis by Kónya (2006) is used. The empirical results indicate that there is a causality linkage between income inequality and fi- nancial globalization in most of the G7 countries. Furthermore, it is shown that income tax has a significant role on the causality linkage. Hence, in order to reduce income inequality, policy makers should apply high taxes on top income, using fiscal policy instruments.
- MakaleAçık Erişim2021The nexus between financial globalization and income inequality: the case of emerging market economies
Çelik, Orkun
We analyze the causality nexus between financial globalization and income inequality for 19 Emerging Market Economies.We use the bootstrap panel causality analysis. The dataset covers the period 1979-2012. The results indicate that there is apositive causality nexus between financial globalization and income inequality. Also, they show that Granger causality runningfrom financial globalization to income inequality is seen in many countries such as Chile, China, Colombia, Egypt, India,Indonesia, Pakistan, and Singapore while there is Granger causality running from income inequality to financial globalizationin Egypt and Iran. Furthermore, there is bidirectional Granger causality in Malaysia, Philippines, and Thailand. The results arenot consistent with the conventional wisdom.
- MakaleAçık Erişim2021The Effect of Public Investment on Gender Inequalities in Employment in Turkey: Spatial Panel Data Analysis
Çelik, Orkun
The main aim of this study is to investigate the impact of regional public investments on male and female employment in Turkey, applying a spatial panel data analysis. The dataset covers for the period 2004-2018 and includes 26 regions at NUTS-2 level. According to the obtained empirical findings, there is a positive spatial interaction in male employment, while there is no statistically significant spatial interaction for female employment. Furthermore, while the impact of the regional public investments on male employment is positive, there is no significant impact of these investments on female employment. The impact of regional investment incentives and regional welfare on male and female employment is positive. This positive effect is higher in female employment. The impact of regional labor productivity on male and female employment is also negative. In addition, a rise in the regional labor productivity leads to further decrease female employment.

Çelik, Orkun; Erer, Elif
We aim to explore the role of gender in the government expenditure and unemployment nexus at regional level for Turkey. For this aim, we use the dataset covering the period 2004-2019 for 26 NUTS-2 regions in Turkey and employ a panel ARDL approach. The obtained empirical findings show that government expenditure and gross domestic product per capita provide overall, female, and male unemployment rates to diminish in the long term, which means the Keynesian approach is valid on the long term. Nevertheless, on the short term, government expenditure induces rises in the male and female unemployment rates. This result indicates the validation of the Abrams Curve Hypotesis in male and female unemployment rates on the short term. Also, inflation rate increases overall and male unemployment rate on the long term, but having significant and positive impact on only female unemployment rate on the short term. All these findings show that gender has a significant role in this nexus. The expected contribution of this study to literature is to investigate the impact of government expenditure on unemployment by gender at regional level for Turkey. We are of opinion that our empirical findings can guide policy makers in active plans fighting unemployment.
- Kitap BölümüAçık Erişim2021Investigation of the foreign direct investment and environmental pollution nexus for developing countries
Çelik, Orkun; Korkmaz, Özge; Adalı, Zafer
In theory, the foreign direct investment and environmental pollution nexus is explained by three hypotheses. Firstly, pollution haven hypothesis assumes that there is a positive nexus between these variables. Secondly, pollution halo hypothesis supposes that there is negative connection between these variables. Lastly, neutrality hypothesis asserts the non-existence of the connection between these variables. In recent years, many researchers have frequently tested whether these hypotheses are valid for different countries. In this study, applying Westerlund panel cointegration test, the authors aim to explore the nexus between foreign direct investment and environmental pollution for 23 developing countries after global crisis. For this aim, they use annual data covering the period 2009-2019. According to the obtained empirical findings, the presence of the long-term nexus between foreign direct investment and environmental pollution is not detected for 23 developing countries. Accordingly, the authors can say that there is neutrality hypothesis.
- Kitap BölümüAçık Erişim2021Energy Policy Recommendations for ASEAN Countries: Empirical Evidence from the Bootstrap Panel Granger Causality Analysis
Adali, Zafer; Korkmaz, Özge; Çelik, Orkun
In social sciences, especially in the economic literature, energy has been one of the most important topics. Energy seems to be dominant on the political and economic agendas because of nearly all economic activities linked to energy. Hence, all economies have endeavored to detect and implement policies to increase their efficiency and mitigate energy’s detrimental effects on the earth. This study’s principal mission is to check the connection between economic growth, non-renewable and renewable energy consumption in ASEAN-5 countries over 1990–2014 to recommend energy-saving policies. Within this view, bootstrap panel Granger causality test is applied. The model results indicate that economic growth causes renewable energy consumption in the Philippines and economic growth induces non-renewable energy consumption in Indonesia and Malaysia. A unidirectional causality relationship operating from renewable energy consumption to economic growth is approved for Brunei Darussalam. Finally, a unidirectional causality relationship working from renewable energy consumption to Brunei Darussalam’s economic growth is confirmed.

- Derleme MakaleYalnız künye2021Assessment of the relationship between renewable energy and employment of the United States of America: Empirical evidence from spectral Granger causality
Çelik, Orkun
In this study, the spectral Granger causality nexus between renewable energy generation and employment for the period February 1973–September 2019 in the USA is examined. The results obtained from the study expresses that there is no spectral Granger causality relationship between renewable energy generation and employment for aforementioned period in the USA. Furthermore, these findings support neutrality hypothesis, which means that there is no causality relation between the variables. In other words, renewable energy generation does not influence employment and employment does not have an effect on renewable energy generation.
- MakaleAçık Erişim2020The impact of technology on employment at regional level: the case of turkey
Çelik, Orkun
Technology has rapidly improved across the world. It has frequently been discussed whether technology creates employment in the literature. There are two different views on this issue. The first is the labor-friendly view that alleges technological innovation creates new job-area. The second is the labor-saving view that asserts technology substitutes capital to labor. This paper analyzes the impact of technology on employment at regional level for Turkey. The dataset covers over the period 2010-2017 for 12 regions at NUTS-I level. According to the results of the system GMM estimation, there is a remarkable nexus between R&D expenditure and overall, man employment, employment of higher education graduates, unlike woman employment. However, the nexus is the inversed U-shape and is clearer in employment of higher education graduates.

Aforementioned dynamics for non-finance sector are also profit, productivity, import, gross domestic product, tax revenue, gross government investment, consumer price index, and unemployment rate. In accordance with this, the most significant dynamic with respect to lis is profit in the non-finance sector, while it is productivity in the business and non-farm sectors.
- MakaleYalnız künye2014Analysis of Public- Private Sector Wage Differentials In Turkey By Quantile Regression Approach
Selim, Sibel; Çelik, Orkun
The topic of wage differentials is a frequently problem in the labor markets of developingcountries such as Turkey. These wage differentials can arise from the market imperfections as wellas the individual quality differences. Individual wage differences are arise from the differences atthe rural and urban area s employees access to the education, the health services and the level ofdevelopment and the other reasons. Wage differences arising from the individual quality differencesfind a large place in The Human Capital Theory. These quality differences reflect on wages overtime and lead to income differences between the individuals. The aim of this study is to analyzeincome differences between male and female employees for public and private sector in rural andurban areas in Turkey. Ordinary Least Squares and Quantile Regression Models results by usingTURKSTAT s Household Labor Force Survey micro data set of 2011 are comparatively discussed.Number of studies that have been made in the literature under the QR model and wage differentialsin the labor market has limited. This study will contribute to the limited literature in terms of basichuman capital as well as the extended models.
- MakaleYalnız künye2013Do Exchange Rates and Budget Deficit Lead to Inflation? A Panel Causality Analysis on Developing Asian Countries
Dogru, Bulent; Recepoglu, Mursit; Çelik, Orkun
In developing economies, budget deficit and exchange rates can lead inflation through shallow financial markets. In this study it is tested whether budget deficit and exchange rates cause inflation in long-run and short-run for 22 developing Asian countries for the time period of 1980 and 2011. The reason why we select all the developing countries from one region is that we assume all countries have fixed unit effect in the models. In this study we use panel cointegration, error correction model and panel causality methods as empiric test. Findings suggest that in short-run there is no causality running from exchange rate and budget deficit to inflation but in long-run budget deficit and exchange rates cause inflation.
