Abstract

fetched live from OpenAlex

Freight railway enterprises in both Europe and North America are in the process of significant restructuring, with EC policy changes dictating new ownership, organization, and cooperation arrangements in Europe and a series of major mergers having already led to highly concentrated regional markets in the U.S. and Canada. Mergers, alliances, and organizational changes may raise important and complex issues regarding the level of competition facing goods shippers, with differing implications depending on the differing institutional contexts. This paper examines the competitive consequences of these developments in Europe and North America and suggests some lessons for other network industries.

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.
