Contaminación como uno de los determinantes de la migración.

Different variables have been proposed to explain the migration phenomenon; recently, environmental degradation has been increasingly prevalent in the literature as a determinant of migration. According to Jha and Wha lley (2003), the environment-migration relationship can be theoretically demonstrated using the traditional Harris-Todaro (1970) model of rural and urban migration, in which the unemployment variable, if interpreted as damage, can be replaced by pollution. Using a cross-section model we present, in this study, evidence for Mexico to support Jha and Whalley, finding a positive relationship between migration and pollution. [ABSTRACT FROM AUTHOR]
