Abstract

fetched live from OpenAlex

Este estudo analisa a demanda dos Estados Unidos pela moldura brasileira. O objetivo foi estimar as elasticidades das principais variáveis que afetam a referida demanda. As estimativas foram obtidas atra-vés do método de mínimos quadrados ordinários, utilizando séries históricas com periodicidade trimestral coletadas entre os anos de 1994 e 2007. Os resultados indicaram respostas: elástica ao preço, altamente elástica a renda, unitária para o preço da moldura chilena, altamente inelástica para o preço da moldura canadense e inelástica para as expectativas. Concluiu-se com base em séries históricas que: o mercado americano dispõe de bons substitutos a moldura brasileira e uma redução no seu preço pode trazer vanta-gens competitivas; o Brasil é altamente dependente de uma expansão econômica dos EUA para aumentar sua parcela de mercado; o produto Canadense foi identifcado pelo mercado dos EUA como diferente ao brasileiro; já a relação com o Chile foi de acirrada concorrência; o comportamento das expectativas apre-sentou uma relação direta, ou seja, um aumento das importações no presente leva a uma expectativa de aumento das importações no futuro. ______________________________________________________________________________________ ABSTRACT

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.
