Environmental Regulations and Air Pollution in India: A Reexamination

Abstract

This paper reexamines the effectiveness of environmental regulations in India, originally evaluated by Greenstone and Hanna (2014) using ground-based monitoring data. Replacing this sparse and inconsistent data with satellite-based reanalysis data reveals contrasting air pollution trends and notable differences in the evaluation of policies' effectiveness. The findings underscore the importance of reliable data for the accurate assessment of policy outcomes in regions with limited monitoring infrastructure.
