Do Vehicle Emissions Testing Program Improve Air Quality?

Kahn, Matthew E.

This paper estimates the impact of the Illinois vehicle emissions testing program on ambient air quality. I find that this program has reduced ozone but has had a smaller than expected impact on carbon monoxide levels. Unlike previous environmental regulation evaluation studies, I control for the fact that regulation is not randomly assigned across geographical areas.
