Abstract

fetched live from OpenAlex

Prior studies show that financial institutions (FIs) engaging in misconduct experience a loss in equity value when regulatory sanctions are publicly announced. These studies rely on datasets for which highly prestigious FIs are overrepresented, however, which may distort the findings. This article addresses this concern by ex ante classifying FIs according to their ex ante reputation. Applying an event-study methodology and the Fama–French model, the authors find that although less-prestigious FIs do not experience a loss in equity value after the announcement of their misconduct, highly prestigious FIs do. They also find a loss in equity value only in misconduct cases with large penalty amounts.

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.
