Abstract
This paper analyzes seller choices and outcomes in approximately 700 recent Internet auctions. The ‘Buy it Now ’ option allows the seller to convert the auction into a posted price market. We use a structural model to control for the (endogenous) conduct of the auction (e.g., number of bids and bidders) as well as product and seller characteristics. Among other things we find that the ‘Buy it Now ’ option was used more often by sellers with higher ratings (awarded by previous buyers) and offering fewer units; and posted prices were more prevalent for used items. Sellers obtained higher prices for unused and undamaged items overall, and especially when selling at the ‘Buy it Now ’ price.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
