Abstract

This paper examines whether the 1990 Clean Air Act Amendments caused the decline in ambient concentrations of particulate matter (PM10) in California over the 1990 – 2000 period. Consistent with previous studies, we find that PM10 non-attainment status at the county level is not a significant factor in explaining the reductions in PM10. However, when we allow for spatially heterogeneous treatment effects within non-attainment counties, and incorporate measures of community characteristics, climate, geography, transboundary pollution and industrial composition and scale, we find that non-attainment designations at the city-level account for a 6% reduction in ambient PM10 concentrations.
