Abstract

Resumen: La hipótesis de la Curva Ambiental de Kuznets (EKC) propone la existencia de una relación en forma de U invertida entre la degradación ambiental y el ingreso per capita. Se ha asumido que esta relación implica que el crecimiento económico eventualmente revertirá los impactos ambientales de las primeras etapas del desarrollo económico. Estudios recientes, como el de Perman y Stern (2003), han mostrado que los métodos econométricos utilizados en los estudios iniciales de la EKC son inapropiados dadas las propiedades temporales de las series. Este trabajo analiza la validez de la hipótesis de la EKC para un panel de 46 países y 20 períodos, implementando pruebas individuales y de panel tanto para raíz unitaria como para cointegración. Se estima, además, un modelo de corrección de error para el panel. Los resultados no apoyan la existencia de una EKC común a los países analizados. / Abstract: The Environmental Kuznets Curve (EKC) hypothesis suggests the existence of an inverted Ushaped relationship between environmental degradation and per capita income. It has been assumed that the environmental impacts occurred during the first stages of the development process will eventually be reverted as a result of economic growth. Several studies, such as Perman and Stern’s (2003), have shown that the econometric methods used in the earlier analysis of the EKC are inappropriate given the time properties of the series. This paper analyzes the appropriateness of the EKC hypothesis for a panel of 46 countries and 20 periods by implementing individual and panel tests for both unit roots and cointegration. An error correction model –VEC– is also estimated for the panel. The results do not support the evidence of a common EKC for the countries analyzed.
