Effective Policies for Transportation and Pollution Reduction on North America’s International Borders

Linda Fernandez and Monica Das


We examine policies of transportation, vehicle technology, environment and trade by impact on air quality along North America’s international borders where trade moves in trucks. Panel data analysis helps account for temporal variation in the implementation of different policies by start date and also enables comparisons between ports on the same border as well as between borders. Data on commercial trucks, private vehicles, border wait times and air pollution are utilized to compare pollution across time and space. We estimate Zellner’s SUR model and Swamy’s random coefficients model to capture heterogeneity in the impact of policies across ports. We find the impact of vehicle technology; trade, security and environmental policies vary across pollutants and ports. Econometric results show trade and security policy are statistically significant in reducing ozone and particulate pollution. Vehicle technology and fuel policy are statistically significant for reducing ozone pollution.
