Economists, ecologists, private industries and government decision-makers have long been interested in the relationships between economic growth and environmental quality. These relationships are often the subject of intense public policy debates such as the current debate surrounding global...

One of the major criticisms of past environmental Kuznets curve (EKC) studies is that the spatiotemporal aspects within the data have largely been ignored. By ignoring the spatial aspect of pollution emissions past estimates of the EKC implicitly assume that a region’s emissions are unaffected...

The carbon Kuznetz curve (CKC) hypothesis assumes that carbon dioxide emissions initially increase in tandem with output but start decreasing at higher levels of output. This paper considers the internal validity of estimating the CKC in an integrated framework of carbon dioxide emissions,...

This paper proposes a semiparametric analysis for the study of the relationship between energy consumption per capita and income per capita for an international panel dataset. It shows little evidence for the existence of an environmental Kuznets curve for energy consumption. Energy consumption...

This study examines the causal relationship between carbon dioxide emissions, energy consumption and real output within a panel vector error correction model for six Gulf Cooperation Council (GCC) countries namely Bahrain, Kuwait, Saudi Arabia, Qatar and United Arab Emirates over the period...

This paper provides empirical evidence of an environmental Kuznets curve (EKC) hypothesis for Portugal by applying autoregressive distributed lag bounds testing approach from 1971 to 2008. In order to capture Portugal’s historical experience, demographic changes and international trade on...

The article aims to look at the long-run equilibrium relationship between per capita greenhouse gas emissions and per capita real GDP (EKC hypothesis) in an asymmetric framework using the non-linear threshold cointegration and error correction methodology for Polish economy during the period...

This study examines the dynamic relationship among carbon dioxide (CO2) emissions, economic growth, energy consumption and foreign trade based on the environmental Kuznets curve (EKC) hypothesis for Indonesia during the period 1971–2007. The Auto regressive distributed lag (ARDL) methodology...

We bridge together the graph-theoretic and the econometric approach for defining causality in statistical models to consider model misspecification problems. By presenting a solution to disagreements between the existing frameworks, we build a causal framework that allows us to express causal...
