The Economic Functions of Referrals and Referral Fee
Bibliographic record
Abstract
As the real estate market becomes more complex, the role of middlemen becomes more central to its efficient operation. Middlemen take on informational roles including marketing, screening, and matching. The real costs incurred in many of these roles are not included in the regulatory authorities' calculations of permitted costs, and become, under RESPA, prohibited as referral fees. This discourages development of innovative packages of products. Regulation specifying the standards for disclosure of referral fees can serve a useful purpose. But the model in this article shows that in at least some circumstances customers will prefer to do business in an environment in which middlemen can choose not to reveal information about any particular referral fee they receive.

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.
