Abstract

fetched live from OpenAlex

Local and organic food are of growing interest to food marketers due to their value-added at tributes, for which many consumers are willing to pay premiums. This research examines how food marketers may be able to more effectively capture these premiums by segmenting consumers by household income and rurality status. Using a stated choice framework covering five different commodities, a personal food value analysis, a conditional log it model, and a comparison of willingness-to-pay distributions were applied in conjunction to examine the differences between these imposed consumer segments. The results suggest that consumer segmentation by household income may be effective for specific local and organic attributes for certain food commodities, but that segmentation by rurality status is likely not effective in any case examined.

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.
