An analysis of the association of forest cover, treated as an environmental good, and income at the county scale in the Northeastern United States was conducted for 2006. Global analysis using a spatial error regression model indicates an environmental Kuznets curve (EKC) type of relationship, with total forest cover, percent forest cover, and forest cover per capita is better associated with p...
مسئله بحرانهای زیست محیطی در سالهای اخیر در محافل علمی اهمیّت بسیار زیادی پیدا کرده است زیرا طی این سالها خطرات و آسیبهای تخریب محیط زیست بیشتر نمایان شده است. اکثر تحقیقات اقتصادی انجام شده در زمینه اقتصاد محیط زیست، به دنبال این مسئله بودهاند که ارتباط معنادار بین تخریب محیط زیست و رشد اقتصادی بیابند (نصیرنیا، 1388). نتایج تحقیقات باعث به وجود آمدن منحنی زیست محیطی کوزنتس (EKC) شده اس...
This study examines the long-run relationship between carbon emissions and energy consumption, income and foreign trade in the case of China by employing time series data of 1975–2005. In particular the study aims at testing whether environmental Kuznets curve (EKC) relationship between CO2 emissions and per capita real GDP holds in the long run or not. Auto regressive distributed lag (ARDL) me...
This present study empiricallyanalyzes the impact of fossil fuel energy consumption on CO2 emission for Pakistan using data from 1980-2010. Our broad objective is to test the environmental Kuznets curve (EKC) hypothesis and factors that affect the energy consumption. We have used Johansen Cointegrationapproach and a Vector Error Correction Model (VECM) to test the long run as well as short run ...
This paper analyzes the Environmental Kuznets Curve (EKC) hypothesis to test the causality relationship between economic activity, trade openness and carbon dioxide emissions in Mexico (1971-2011). The results achieved in this research show that there are three long-run relationships between production, trade openness, energy consumption and carbon dioxide emissions. The EKC hypothesis was not ...
The purpose of the paper is to test empirically the existence of an environmental Kuznets Ž . curve EKC , using switching regime models along with cross-sectional data and Bayesian Markov chain Monte Carlo methods to perform the computations. The models are based on the normal and Student’s t distributions. These methods allow us to present exact, finitesample posterior distributions of switchi...
A method for the separation of twelve monomethyl-substituted benz[a]anthracene isomers using poly-(sodium undecylenic sulfate) (poly-SUS) surfactant by means of electrokinetic capillary chromatography (EKC) is described. Several parameters such as concentration of acetonitrile (ACN), pH, as well as applied voltage were studied to optimize the EKC separation. ACN at a concentration of 35% v/v, 1...
From April to November 2016, two outbreaks of epidemic keratoconjunctivitis (EKC) occurred successively at primary and middle schools in the Tibet Autonomous Region of China, and a total of 197 clinically diagnosed cases were reported. Real-time PCR analyses confirmed that human adenovirus (HAdV) infection was related to these outbreaks. Further studies involving sequence determination and phyl...
The aim of this paper is to investigate the long run relationships among the Energy, Environment and the Economy (E-E-E). This paper also tests the Environmental Kuznets Curve (EKC) for the case of Pakistan. We find robust long run relationships between energy, environment and economic growth. It is also found that the capital and labor elasticities of income show decreasing returns in the pres...
If the EKC holds, we might be tempted to make an even stronger statement: growthpromoting policies in less developed countries (LDCs) cause incomes to rise and are thus environmentally friendly. We do not need to bother negotiating with developing countries to reduce emissions. Let LDCs develop, and they will eventually solve their own environmental problems, even if in the short run pollution ...
