Abstract

fetched live from OpenAlex

This research investigated the timing of marketing decisions in the Canadian wheat market. Cox proportional hazard models were estimated to explore how the timing of producers’ decisions were affected by market-based variable, which included an indicator showing whether current prices were above producers’ benchmark on a given day, 10-day average spread between current prices and producers’ benchmark, 10-day price trend and price volatility over 10 days. Marketing data for 17,338 producers who executed 59,184 transactions between 2003/04 and 2008/09 were used in the analysis. Overall results indicate that all variables affected timing decisions in producers’ marketing choices. However, the signs of the estimated coefficients tended to vary across contracts and years, suggesting that producers could change their pricing behavior over time and response to the covariates could also depend on characteristics of the contracts and how they relate to producers’ marketing strategies.

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.
