Abstract

fetched live from OpenAlex

Abstract: During the last decade the Internet has become an increasingly important source for gathering company related information. We employ Wikipedia editing frequency as an instrument that captures the degree in which the population is engaged with the processing of company‐related information. We find that firms whose information is processed by the population more frequently are associated with lower analysts' forecast errors, smaller analysts' forecast dispersions, and significant changes in bid‐ask spreads on analysts' recommendation days. These results indicate that information processing over the Internet is related to the degree to which investors and analysts are informed about companies.

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.
