Import demand for Chilean table grapes in the United States market
Bibliographic record
Abstract
This paper studied the United States import market for Chilean table grapes, with the objective of analyzing the competitiveness of Chile in this market. Using the LA/AIDS model (Linear Approximation almost Ideal Demand System), the import demand parameters were obtained for Chile, Mexico and the rest of the world (RDM). Quarterly data were used for import quantities, import values, and CIF (Cost, Insurance, and Freight) prices for the period between the first quarter of 1989 and second quarter of 2002. Own price elasticity estimates indicated inelastic demand for all three countries with values of -0.79, -0.86, and -0.82, for Chile, Mexico, and RDM, respectively. Cross price elasticities between Chile and Mexico indicated significant substitution relationships, which was further supported by a partial elasticity of substitution equal to 0.51. Jointly these results showed that although Chile has a strong position in this market, Mexico has also positioned itself as a potential competitor in those quarters where both countries overlap.

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.
