Abstract
Canada has paid great efforts to reduce interprovincial trade barriers in order to establish an integrated local economy. In order to assess the cross-border movements of goods across provinces and territories, this paper examines the price index convergence of food products within Canada from 1997 to 2016. Since the cointegrating relationship between food product prices may not be exact or linear, we adopt the rank tests for analysis which do not require prior knowledge and specification of the linear or nonlinear functional form. Our results validate the price convergence of all food products under study within Canada and show that government initiatives are effective. Furthermore, a subset of the cointegration relationships exhibits nonlinear long-run price co-movements.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
