Services and informality: the itinerant trade in Rio de Janeiro
Bibliographic record
Abstract
O trabalho demonstra que, para os anos 90, o avanço das atividades ligadas à economia informal não se apresenta mais como fenômeno transitório na sociedade brasileira, mas como fato comprovado empiricamente para as principais regiões metropolitanas. Analisando o comércio ambulante, fica nítida a tendência da economia do Rio de Janeiro de continuar sofrendo um lento processo de esvaziamento econômico: a população economicamente ativa (PEA) e a população ocupada (PO) regional tiveram as menores taxas de expansão de todas as regiões metropolitanas, enquanto a participação dos ambulantes teve crescimento positivo. A relação destes últimos com a PEA apresenta a segunda trajetória mais expressiva da economia metropolitana nacional. Assim, pode-se concluir que o Rio de Janeiro se mantém na rota de precarização das relações de trabalho. O artigo analisa ainda o perfil dos ambulantes metropolitanos do Grande Rio, segundo sexo, idade, escolaridade, posição na família e rendimentos.

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.
