this study attempts to investigate the relationship between pollution and economic growth for two groups of countries according to environmental kuznets curve hypothesis for a sample of 24 developing countries and 26 oecd countries over the period 1980 - 2005. then, we examine this hypothesis using modern econometrics techniques including panel co-integration and panel unit-root. the panel data...

The relationship between per capita municipal water use (PCMWU) and gross domestic product (PCGDP) (purchasing power parity, constant 2011 US$) is statistically analysed for each country in the world. results indicate that PCMWU will increase with rising PCGDP at beginning, which then decrease when reaches a certain level. This trend follows rules of Water Use Kuznets Curve, an inverted U-shape...

The paper provides a political economy theory of the Kuznets curve. When development leads to increasing inequality, this can induce political instability and force democratization on political elites. Democratization leads to institutional changes which encourage redistribution and reduce inequality. Nevertheless, development does not necessarily induce a Kuznets curve, and it is shown that de...

In this paper we discuss three important econometric problems with the estimation of Environmental Kuznets Curves, which we exemplify with the particular example of the Carbon Kuznets Curve (CKC). The Carbon Kuznets hypothesis postulates an inverse U–shaped relationship between per capita GDP and per capita CO2 emissions. All three problems occur in the presence of unit root nonstationary regre...

in this paper, we have calculated the environmental efficiency for india, turkey, egypt and iran. the results show that iran’s environmental efficiency has experienced a decreasing trend from 1991 to 2007and india, turkey, egypt and iran have the highest environmental efficiency, respectively. we also have investigated the environmental kuznets curve for this period using data envelopment analy...
