We study how the import of older and more polluting technologies alters the relationship between output and environmental quality in developing countries within a vintage capital framework. Our results show that old technologies prolong the period until which pollution may eventually decrease and cause this turning point to be reached at a higher level of pollution. An empirical analysis using export data of vintage technologies from the US and Europe to developing countries supports our theoretical findings.
