NAFTA at 20: North America's Free-Trade Area and Its Impact on Agriculture
Bibliographic record
Abstract
This report examines the integration of North America’s agricultural and food markets as a result of the North American Free Trade Agreement (NAFTA), implemented in 1994. NAFTA has had a profound effect on many aspects of North American agriculture over the past two decades. With a few exceptions, intraregional agricultural trade is now completely free of tariff and quota restrictions, and the agricultural sectors of the member countries—Canada, Mexico, and the United States—have become far more integrated, as is evidenced by rising trade in a wider range of agricultural products, substantial levels of cross-border investment, and important changes in consumption and production. The report also examines recent disputes among its constituents and identifies opportunities for further reforms of mutual benefit to the member coun tries, with particular attention devoted to the NAFTA governments’ efforts to seek deeper regional integration through such means as regulatory cooperation and modifying the agreement’s rules of origin and broader access to markets in other parts of the world through the negotiation of additional free-trade agreements.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
