Cross-border Dynamics and Informal Markets between Colombia and Venezuela: The Case of Cúcuta and San Antonio
Bibliographic record
Abstract
This paper explores some of the cross-border dynamics in Cucuta, Colombia, and Ureña/San Antonio, Venezuela, particularly highlighting the interplay of informal markets and illicit border crossings, known as trochas. This study considers the significant changes that have transformed the Colombia-Venezuela border landscape over the past two decades. The essential function that trochas play in sustaining these cross-border interactions is underscored, as is the resilience of local inhabitants who eke out a living through informal labor and participation in various illicit markets along this border segment. The ethnographic evidence presented is derived from multiple visits to the region conducted from 2016 to 2022, offering an illuminating portrayal of these border zones and the variety of trade relations that prevail within the named cities. These relations encompass a broad spectrum of both legal and informal activities, including the smuggling of goods.

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.
