Abstract

fetched live from OpenAlex

We analyze the correct selling order in a second-price sequential auction for two heterogeneous synergistic goods with local and global bidders.We prove that as the number of local bidders in the second auction approaches infinity, the outcome is always efficient.However, as the number of local bidders in the first auction approaches infinity, the outcome is inefficient with a positive probability.By using simulations, we show that selling the good with more finite bidders in the second auction results in a more efficient outcome.If the selling order is incorrect, the probability of an inefficient outcome is around 19%.

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.
