Abstract
Port logistics activity is a vital element in foreign trade. In a globalized environment that demands greater competitiveness, trade agreements and synergies between trade blocs through maritime transport allow commercial development between economies. This research analyzes the relationship between international trade through seaports and investment in the countries that make up the North American Free Trade Agreement (NAFTA) from 1997 to 2017. An econometric panel data model is used to measure the relationship between the variables, and unit root tests, cointegration tests (Kao and Fisher-Johansen tests), and heterogeneous causality tests (Hurlin and Dumitrescu test) are performed. The results show a positive relationship between trade and productivity, as well as a positive relationship between commerce and direct foreign investment; hence, an increase in investment causes a growth in international trade between Mexico, the United States, and Canada.

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
