The environmental Kuznets curve for US counties: A spatial econometric analysis with extensions

Abstract: Abstract. We examine the relationship between county per capita income and toxic pollutants using a comprehensive model of the Environmental Kuznets Curve. The model incorporates ethnic diversity, spatial effects and most independent variables used in previous studies. Initial results suggest that the relationship follows an inverted‐U‐shape. However, incorporation of a cubic term for income reveals that toxic pollution eventually increases again as income continues to rise. Ethnic diversity and spatial effec… Show more

“…These effects should be considered by creating an EKC. Rupasingha, Goetz, Debertin, and Pagoulatos () find a more cubic than inverted‐U‐shaped relationship between county per capita income and toxic pollutants, also affected by ethnic diversity. A comprehensive survey of the EKC hypothesis up to the year 2004 is provided by Dinda ().…”

“…Spatial models were first used as a tool for assessing the EKC hypothesis by Rupasingha et al (2004). Extending the use of more sophisticated econometric approaches, Maddison (2006) studied a spatial variant of the EKC hypothesis for national emissions of SO 2 and NO x and found evidence that national emissions are lowered by proximity to nations with high per capita income, contradicting the notion that nations must achieve increased environmental quality at the expense of their neighbors.…”

“…Some of them adopted spatial econometrics models to verify the relationship between air pollution and economic growth [17,18]. Rupasingha et al [19] were the first to consider spatial autocorrelation in their empirical analysis of the Environmental Kuznets Curve. Zhu et al [20] demonstrated a significant positive spatial effect of foreign direct investment (FDI) on SO 2 emission in the BTH region.…”
