Um panorama da previdência social dos trabalhadores da Economia Gig do setor de transporte no Brasil
Bibliographic record
Abstract
Technological advances have been transforming work relationships. Non-traditional work relationships are growing and conquering the space of traditional contracts. Consequently, ensuring adequate coverage of social protection systems for these evolving work relationships becomes a pressing challenge. This study undertakes an estimation of Gig Economy workers within Brazil’s transport sector, using microdata from the Continuous National Household Sample Survey (Pnad Contínua) by the Brazilian Institute of Geography and Statistics (IBGE). The primary aim is to furnish valuable insights for the formulation of public policies geared towards enhancing social security inclusion. The estimation methodology pivots on two principal variables: occupation and the economic activity undertaken by these workers. The findings underscore that during the third quarter of 2022, the total count of Gig Economy workers in the transport sector surged to 1.7 million individuals; remarkably, a mere 23% of this cohort contributed to the Social Security system.

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.
