Separability, spillovers, and segmented markets : Evidence from dairy in India
Bibliographic record
Abstract
Abstract A long history of empirical research has focused on testing whether and when household consumption and production decisions are separable. If markets were perfect, household consumption would be independent of production. In this article, we propose that market channel choice complicates this relationship. Our analysis of household panel data from rural India, focusing on dairy, leads us to four key conclusions. First, milk consumption is correlated with production, and markets are not a complete substitute for household production. Second, a large presence of formal milk buyers in a village is associated with lower milk consumption in dairy households, overturning the positive association of participation in formal value chains with household milk consumption. Third, contrary to expectations, for households that do not own dairy animals and net buyers, the presence of formal value chains remains uncorrelated with milk consumption. Fourth, we infer, test for and find suggestive evidence of segmented milk markets, that is, different types of households participate in different markets for milk that do not seem to interact with each other. Policymakers focused on market development or production‐based strategies need to factor in the possibility of market segmentation based on market channels while designing interventions.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
