Abstract

fetched live from OpenAlex

Public goals of allocative and distributional efficiency can be assumed only in market-like relationships. The questions that follow are how can, and when should, the public intervene to encourage electronic markets, rather than electronic hierarchies, to develop? This thesis explores the concept of an electronic market to allocate rail cars, as originally proposed by Prentice (1998), as a means of introducing competition in the grain transport industry. A case study of the administered rail car allocation system finds; that electronic market processes exist with the exception of a missing membership structure. A not-for-profit corporation, here called the "Rail Car Authority", would complete the necessary Reimers pre-conditions. The Rail Car Authority would be responsible for sustaining a fleet of covered hopper cars for the transport of Western Canadian grain, and for ensuring equitable and efficient access by shippers to these rail cars.

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.
