CHANGING PATTERNS OF REGIONAL AND INTERNATIONAL TRADE: The Case of Canada Under NAFTA
Bibliographic record
Abstract
Recently, the issue of regional and international trade flows has attracted increased attention. Papers by Helliwell and McCallum have stressed the importance of national borders in determining the nature of Canadian economic activity even when adjustments are made for distance and trade barriers. This article, using Provincial Economic Accounts data, estimates an almost ideal demand system to explain the interprovincial and international flow of goods, accounting for changes in relative prices and other factors that have arisen since the formation of NAFTA. The results allow conclusions to be drawn with respect to the importance of geographical proximity to the U.S. border, the influence of price and income elasticities, and the nature of the industrial/resource endowment mix of the province. The relevant elasticities allow for the examination changes to the internal and external trade patterns and to the differences which have developed in the various regions of Canada.

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.
