California’s Agriculture-Related Local Air Pollution Policy

An Assessment of the Effectiveness of California’s Local Air Pollution Controls on Agricultural Sources

Do Smog Checks Affect Smog? Emissions Inspections, Station Quality and Local Air Pollution

Personal automobile emissions are a major source of urban air pollution. Many U.S. states control emissions through mandated vehicle inspections and repairs. But there is little empirical evidence directly linking mandated inspections, maintenance, and local air pollution levels. Using individual-level data from 1998–2012 from California’s inspection program, we estimate the contemporaneous eff...

Technology and the Effectiveness of Regulatory Programs Over Time: Vehicle Emissions and Smog Checks with a Changing Fleet

Personal automobile emissions are a major source of urban air pollution. Many regional and local governments across the United States (US), Europe, and Asia have inspection and maintenance (I/M) programs designed to reduce pollution from personal transportation. But there is little empirical evidence directly linking mandated inspections, maintenance, and local air pollution levels. To test for...

Environmental Justice and Climate Policy: Is California’s Cap and Trade Failing Disadvantaged Communities?

Pollution pricing policies offer advantages over traditional environmental regulation in compliance flexibility and cost effectiveness, but introduce more uncertainty over where emissions will occur. Consequently, environmental justice organisations have raised equity concerns about California’s flagship cap-and-trade program; greenhouse gas emissions trading could generate increased local conc...

Practice of Epidemiology Exposure to Traffic-related Air Pollution During Pregnancy and Term Low Birth Weight: Estimation of Causal Associations in a Semiparametric Model

Traffic-related air pollution is recognized as an important contributor to health problems. Epidemiologic analyses suggest that prenatal exposure to traffic-related air pollutants may be associated with adverse birth outcomes; however, there is insufficient evidence to conclude that the relation is causal. The Study of Air Pollution, Genetics and Early Life Events comprises all births to women ...
