Abstract

fetched live from OpenAlex

We analyze more than 11,000 private placements raised in Canada between 1998 and 2004, before and after the adoption of two new rules, one extending the exemptions for private placements and the other reducing the escrow periods for restricted securities. Consistent with the findings of the Ontario Securities Commission, we observed considerable growth in the proceeds raised. However, this growth originates from funds (including financial institutions and limited partnerships). The regulation thus fails to facilitate the financing activities of small and medium sized enterprises, particularly non-reporting issuers. If the number of placements increased, the total amounts collected monthly by reporting and non-reporting issuers decreased slightly after the adoption of the new rules.

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.
