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.

How this classification was reachedexpand
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.
