Abstract

fetched live from OpenAlex

Using Montreal as a case study, the authors investigate whether overlapping labor markets explain economic links between the suburbs and the central city. Despite interconnection between labor markets, they find only weak evidence of commuting ties between particular suburbs and the city center. However, economic functions—but also some services and amenities—are distributed unevenly across the metropolitan area. The authors suggest that other connections, such as those generated by occasional consumption activities, interfirm exchanges, and other weak ties could be explored to more fully understand the economic ties between constituent parts of metropolitan areas.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
