Demanda interna e comércio internacional do trigo
Bibliographic record
Abstract
That work aims to analyze past and current international scenario for wheat, as well as estimate domestic and international demand functions of it. For the empirical purposes, the domestic demand was based upon a system of simultaneous equations for quarterly data in the period 1996.1 – 2003.4. Regarding the international demand function, the methodology was supported by a panel data econometric model, where cross-sectional data accounted for countries in South America – Argentina, Brazil, Uruguay, Chile and Venezuela – and North America – Mexico, Canada and United States, for the yearly series of 1997-2004. The domestic model estimates for the demand was satisfactorily identified by a significant negative price effect. But, contrary to theoretical expectation, income effect was negative which imply, by substitution effect, that as national income rises, wheat is substituted by other products. Also, as expected, wheat is very sensitive to exchange rate, but not to domestic inflation. The international demand for wheat follow similar pattern to the domestic one regarding price and per capita income effects, as well as the insignificancy of domestic inflation on wheat consumption.

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; both teacher heads agree on what is shown here.
