Abstract

fetched live from OpenAlex

This study formally tests the hypothesis that markets for Alaska lumber and logs are integrated with those of similar products from the U.S. Pacific Northwest and Canada. The prices from these three supply regions are tested in a common demand market (Japan). Cointegration tests are run on paired log and lumber data. Our results support the conclusion that western hemlock (Tsuga heterophylla (Raf.) Sarg.) and Sitka spruce (Picea sitchensis (Bong.) Carr.) logs from Alaska share an integrated market with logs produced in the other two regions. Results are less clear for lumber. Given this evidence that markets are at least imperfectly integrated, Alaska production and exports of forest products will continue to be sensitive to international market conditions, including competition from other North American producing regions.

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.
