Abstract

fetched live from OpenAlex

When disaster strikes, the weak suffer mightily, the strong only slightly. That is the lesson from stock market reactions to COVID-19. Strong firms had a robust financial position, advanced environmental and social performance, and were not severely exposed to social distancing and lockdowns. Firms with significant international exposure suffered more, at least at first. The ultimate effects of policy interventions, including those by central banks, have yet to be revealed. The market recovery in the second quarter of 2020 is like a patient recovering from COVID-19: hopeful but still uncertain. Managers and policymakers should project the future with great caution.

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.

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.
