Abstract

fetched live from OpenAlex

Transportation services help the NAFTA economy. Traffic congestion and delays at border ports of entry among NAFTA countries result in two negative consequences of poor air quality and delayed trade flows. Econometric analysis and panel data is applied to assess whether NAFTA resulted in more pollution at border ports of entry related to transportation services and whether policies under NAFTA helped alleviate delays and reduce air pollution at the shared transboundary ports of entry. Panel data for use consist of variables that include air pollutants, frequency and magnitude of transportation flows (including commercial trucks, passenger vehicles) for ports of entry along both the Canada-U.S. border and the Mexico-U.S. border. The paper offers an assessment of the environmental impact of trade liberalization on the cross border trucking sector in North America, using econometrics and panel data from the time period covering NAFTA and of the connections between trucking, air quality and trade are made for the U.S., Canadian and Mexican trucking services industry. Then the econometric method and

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
