Export product diversification and the environmental Kuznets curve: evidence from Turkey

Countries try to stabilize the demand for energy on one hand and sustain economic growth on the other, but the worsening global warming and climate change problems have put pressure on them. This paper estimates the environmental Kuznets curve over the period 1971-2010 in Turkey both in the short and the long run. For this purpose, the unit root test with structural breaks and the cointegration analysis with multiple endogenous structural breaks are used. The effects of energy consumption and export product diversification on CO2 emissions are also controlled in the dynamic empirical models. It is observed that the environmental Kuznets curve hypothesis is valid in Turkey in both the short run and the long run. The positive effect on energy consumption on CO2 emissions is also obtained in the long run. In addition, it is found that a greater product diversification of exports yields higher CO2 emissions in the long run. Inferences and policy implications are also discussed.

Evaluating the efficiency of nuclear energy policies: an empirical examination for 26 countries

The decarbonization of the global economy is an urgent concern. As a potential solution, it can be important to understand the efficiency of nuclear energy policies. For this purpose, the paper analyzes whether there is a unit root in nuclear energy consumption in 26 countries and it uses the unit root tests with two endogenous (unknown) structural breaks. The paper finds that nuclear energy consumption is stationary around a level and the time trend in 25 of 26 countries and nuclear energy consumption contains a unit root only in France. The paper also discusses the potential implications of the findings.

Globalization, Inequality, and Redistribution: Theory and Evidence

This paper constructs a simple theoretical model to study the implications of globalization for inequality and redistribution. It shows that when globalization increases inequality, a policymaker interested in maximizing the sum of welfares of all agents increases redistribution. Empirically, the paper examines the effects of globalization on inequality and redistribution in a panel data set of 140 countries for the period from 1970 to 2012. It finds that both inequality and redistribution have been increasing with globalization. The results are robust to the inclusion of many different controls and the exclusion of outliers.

The impact of economic complexity on carbon emissions: evidence from France

This paper reanalyzes the determinants of the CO2 emissions in France. For this purpose, it considers the unit root test with two structural breaks and a dynamic ordinary least squares estimation. The paper also considers the effects of the energy consumption and the economic complexity on CO2 emissions. First, it is observed that the EKC hypothesis is valid in France. Second, the positive effect of the energy consumption on CO2 emissions is obtained. Third, it is observed that a higher economic complexity suppresses the level of CO2 emissions in the long run. The findings imply noteworthy environmental policy implications to decrease the level of CO2 emissions in France.

Causal Linkages among the Product Diversification of Exports, Economic Globalization and Economic Growth

This paper examines causal relationships between economic globalization, the three indices for product diversification of exports (Theil index, intensive margin and extensive margin) and economic growth in the unbalanced panel data framework in 139 countries over the period 1970–2010. We also consider the subgroup of the countries related to the income levels and run the panel Granger non-causality tests for heterogeneous panels. The empirical results indicate that there is a bidirectional causal relationship between economic globalization and economic growth. There is also a significant causal relationship that runs from all three indices for the diversification of exports to economic growth. After implementing various robustness checks, we observe that diversification of exports and economic globalization are positively related with economic growth merely in the upper middle economies.

Dynamic Relationships Among CO2 Emissions, Energy Consumption, Economic Growth, and Economic Complexity in France

Environmental degradation is most often brought to the agenda by arousing the attention of scholars, and there has been an increase in the studies on this issue. This paper re-estimates the environmental Kuznets curve in France over the period of 1964–2011. To this end, the unit root test with one structural break and a cointegration analysis with multiple endogenous structural breaks are considered. The impacts of the energy consumption and the economic complexity on CO2 emissions are also included in dynamic empirical models. First, it is found that the environmental Kuznets curve hypothesis is valid in France in both the short and the long run. Second, the positive impact of energy consumption on CO2 emissions is also observed in the long run. Third, it is observed that a higher economic complexity suppresses CO2 emissions in the long run. The evidence suggests important environmental policy implications to suppress CO2 emissions in France.

Does Export Product Quality Matter for CO2 Emissions? Evidence from China

This paper re-estimates the environmental Kuznets curve (EKC) in China. To this end, it uses the unit root tests with structural breaks and the autoregressive-distributed lag (ARDL) estimations over the period 1971–2010. The special role is given to the impact of export product quality on CO2 emissions in the empirical models. The paper finds that the EKC hypothesis is applicable in China. It also observes the positive effect from energy consumption to CO2 emissions. In addition, it finds that the export product quality is negatively associated with CO2 emissions. The paper also argues potential implications.

Robustness of the KOF index of economic globalisation

The KOF indices of globalisation are the most used globalisation measures in international economics literature, but it uses the nominal trade openness measure to construct the globalisation index. In this paper, we use real trade openness instead of nominal trade openness and recalculate the KOF economic globalisation index over the period 1970–2013. Using the panel data regressions for 146 countries, we revisit the economic globalisation–economic growth nexus to investigate the robustness of the KOF economic globalisation index. We consider several possibilities in model specifications, and the results show that using nominal trade openness measure in calculating the KOF globalisation index is statistically robust. In addition, the KOF economic globalisation index in logarithmic form introduces a more robust outlook in the panel data regressions—a lower bias is emerged by considering different trade openness measures to calculate the globalisation level.

Does trade matter for carbon emissions in OECD countries? Evidence from a new trade openness measure

This paper analyzes the impacts of the per capita income, the per capita energy consumption, and the trade openness on the level of per capita carbon emissions in the panel dataset of 35 Organization for Economic Cooperation and Development (OECD) countries over the period 1960–2013. Along with the nominal trade openness, the paper uses a different trade openness measure, so called as the “trade potential index” (TPI). To the best of our knowledge, this is the first paper that uses the TPI in the empirical environmental Kuznets curve (EKC) hypothesis literature. The paper finds that the EKC hypothesis is valid and there is an “inverted-U” relationship between the income and the carbon emissions. In addition, the paper observes that there is a positive effect of the energy consumption on the carbon emissions. Furthermore, the results indicate that both trade openness measures are negatively associated with the carbon emissions in the OECD countries in the long run.

The effects of the military in politics on the inbound tourism: evidence from Turkey

ABSTRACT In this paper, we analyze the effects of the military in politics on the number of tourist inflows from 71 countries to Turkey for the period from 1984 to 2014. We use the fixed-effects and the random-effects as well as the dynamic generalized methods of moments estimations. We find that a lower level of the relative military in politics (the difference between the source country and Turkey) positively affects the tourism inflows to Turkey. Specifically, one standard deviation reduction in the index of the relative military intervention in politics in Turkey leads to almost 7% increase in the tourism inflows.
