Abstract

fetched live from OpenAlex

Abstract We build on recent advances in options pricing research to propose a novel measure of the ex ante relative importance of information events. Our firm‐level measure captures the extent to which investors view an event as important, independent of its realized outcome. We first validate the measure and then demonstrate how it can be used to (1) study heterogeneity across firms in the relative importance of information events; (2) identify firms for which an event was important, even though the realized outcome did not result in a meaningful stock reaction; and (3) examine questions about how the importance of an event impacts firm decisions, where using realized return‐based measures of event importance would result in an endogeneity problem.

Full frame distilled prediction

Teacher imitation

Not 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.
