Abstract

fetched live from OpenAlex

This paper investigates the spatial integration of Niger cereal markets using monthly retail prices of four staple crops consumed daily in the country. We used co-integration techniques to analyze the price relationship between six main markets. The results revealed high co-integration in Millet and Maize market pairs. On the Contrary, the study indicates also high absence of co-integration in most of Rice and Sorghum markets. Many factors such as poor infrastructures, government interventions, may be major impediments to spatial integration between markets. Development of private grain marketing will help to improve trading between markets, thereby increasing competition and circulation of grain from surplus areas to supply deficit areas.

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.
