La théorie économique des choix de carrière : une interprétation et une vérification empirique
Bibliographic record
Abstract
In their choice of a field of study, students are assumed by the "neoclassical" theory to be rational, well informed, flexible, and to react to changes in monetary variables. Data from a survey are used to show that students are economic men and women only in a weak sense: 1) they appear to be more interested in job availabilities and other job characteristics than in earnings associated with a particular field of study; 2) if their information can be said to be good with respect to forgone earnings and starting earnings of their chosen occupation such is not the case with respect to future earnings; 3) however, their expected rates of return on their studies seem plausible and show all the usual properties of rates of return derived from more conventional computations.
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.

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.
