Abstract

fetched live from OpenAlex

Abstract Many development programs rely on the idea that increasing profitability of small‐ and medium‐sized enterprises (SMEs) could increase availability of nutritious foods among low‐income consumers. We designed a randomized controlled trial in which we made a specific nutritious product produced by an SME exhaustively available in low‐income local markets. We find that compared to control markets, consumers in treated markets purchased and consumed more of this product and less of competing brands with added sugar and fat. However, overall consumption for the product category was not increased and there was no change in the consumption of other related but potentially less nutritious foods. Our findings suggest the need for alternative policies to increase consumption of nutritious foods.

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.
