Is Commodity Storage an Option for Enhancing Food Security in Developing Countries?
Bibliographic record
Abstract
Abstract We revisit the underlying economics of commodity storage and its relation to food security by first clarifying the standard model used to analyze the economic efficiency and distributional effects of commodity storage programs. We find that producers prefer stabilization, although their incomes are more variable, while consumers are indifferent. However, numerical simulations indicate that physical stocks will build up inexorably over a sustained period or the government will need to raise prices continuously over a prolonged period. For the least developed countries facing fluctuating world prices, government should guarantee the price received by producers because, with price uncertainty, farmers could experience losses even under a ‘good’ weather outcome; this would guarantee the producer price, benefitting farmers, while allowing the consumer price to vary with the world price benefits consumers as they prefer price instability. In some cases, however, the government may wish to impose a price ceiling so that households living at or near subsistence can afford to buy grain – an argument based on the grounds of food security. Numerical simulations indicate that such a mixed-price policy increases the wellbeing of both consumers and producers. Physical storage is not a necessity.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
