Time-varying disaggregation of the income-emissions nexus: New evidence from the United Kingdom.

This paper's objective is to investigate the validity of the Environmental Kuznets Curve (EKC) hypothesis utilizing three unique approaches in this era of accelerating climate change and economic volatility. The first step is to introduce and employ a new cointegration test which allows smooth and sharp structural changes through a dummy variable and a Fourier function. Using a time-varying causality approach, the second stage is to assess the EKC hypothesis's validity for each year of a given period, as opposed to the entire period.

Testing the Short, Medium, and Long-Term Effects of Shocks on Ecological Balance.

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.

Does the frequency of stochastic convergence in per capita ecological footprint matter?

Among the environmental economics research issues, the issue of convergence has received quite a lot of attention, which is also known as stationary analysis. In this research strand, whether shocks to the time series variable are permanent or temporary is tested via the unit root tests. In this study, based on the theory and empirical works of stochastic convergence, we evaluate the convergence for the BASIC member countries, including Brazil, South Africa, India, and China.

Identifying the roles of energy and economic factors on environmental degradation in MINT economies: a hesitant fuzzy analytic hierarchy process.

Globally, research communities have been studying the different determinants of environmental degradation or pollution using different contexts and methods. In this study, we identify several energy and economic factors, such as energy consumption (EC), gross domestic product (GDP), energy production (EP), urbanization (URB), and foreign direct investment (FDI) as the most effective factors of environmental degradation by obtaining several environmental researchers' opinions and using the hesitant fuzzy analytic hierarchy process. In the later stage of the analysis, we use these variables as regressors of the ecological footprint (EF) as a proxy for environmental degradation.

Pollution haven or pollution halo in the fishing footprint: Evidence from Indonesia.

This study tests the pollution halo/haven hypothesis and the environmental Kuznets curve (EKC) in Indonesia by considering the fishing footprint (FF) as the environmental degradation indicator over the period 1976-2018. The results provide evidence of the validity of the pollution halo hypothesis and the EKC. Besides, we found that trade openness in the fishery sector harms the FF.

Convergence in ecological footprint across the member states of ECOWAS: evidence from a novel panel unit root test.

In this paper, we investigate the convergence in ecological footprint per capita across the ECOWAS (Economic Community of West African States) countries from 1968 to 2017. For this aim, we apply a panel Fourier threshold unit root test recently proposed by Yilanci et al. (2021).

Technology spillovers and sustainable environment: Evidence from time-series analyses with Fourier extension.

Globalization and human capital accumulation are the main drivers of technology spillovers and essential for economic growth. At the same time, globalization and human capital are drivers to construct a green growth path that prevents pollution and the overuse of resources, and thus mitigates environmental degradation and achieves sustainable development. This mechanism, known as the 'technique/technology effect', may occur by stimulating technological development and creating environmental awareness and is of utmost importance in developed and developing countries to protect the environment.

Does economic globalization have predictive power for ecological footprint in MENA counties? A panel causality test with a Fourier function.

Recently, there has been renewed interest in the relationship between economic globalization and environmental pollution since various globalization indices are developed. Although several attempts have been made to investigate the impact of globalization on the environment, no known empirical research has focused on exploring the causal relationship between ecological footprint and economic globalization index (provided by KOF Swiss Economic Institute) considering also its subcomponents-trade and financial globalization indices. In this study, a new panel data technique for the causality analysis is developed (namely, panel Fourier Toda-Yamamoto approach) and applied to ecological footprint-economic globalization nexus in 14 MENA (Middle East and North Africa) countries during the period 1981-2016.

Investigating the EKC hypothesis for China: the role of economic complexity on ecological footprint.

This empirical study aims to test the validity of the environmental Kuznets curve (EKC) hypothesis for China within the framework of (Narayan and Narayan Energy Policy 38(1):661-666, 2010) approach. To this end, the study employs a recently developed Fourier ARDL procedure and time-varying causality test over the period 1965-2016 to analyze the short- and long-term relationships between economic growth, economic complexity index, energy consumption, and ecological footprint. The findings of the Fourier ARDL procedure confirm the existence of cointegration among the series.

Testing the environmental Kuznets curve for G7 countries: evidence from a bootstrap panel causality test in rolling windows.

The Environmental Kuznets Curve hypothesis is a theoretical proposition explicating the link between a locality's income level and environmental degradation. Previous studies estimated the current relationship with an unchanging parameter. However, due to changes in global conomic and political conditions, natural disasters, technological shocks, and implemented policies, the link between income and environmental degradation is about to change.

Is health care a luxury or a necessity or both? Evidence from Turkey.

This study investigates the effect of per capita income on per capita health expenditures in Turkey over the period 1975-2007 by using ARDL bounds test approach to the cointegration considering both demand and supply side variables. Since we reject the null hypothesis that there is no cointegration among the series, we estimate long run and short run elasticities. The results show that while income has no effect on health expenditures in the long run, it is a necessity good in the short run that is a 1% increase in per capita income creates an 0.
