Abstract

fetched live from OpenAlex

Road traffic accidents mean lost productivity and medical expenditures. We explain trends in traffic accidents as a function of the political cycle using municipal data from Italy. We show that during municipal election years, the accident rate increases by 1.5%, with a 2% increase in the injury rate but no effect on the fatality rate. The effects are stronger in the quarter prior to the election quarter, when the electoral campaign is at its zenith, and in the second quarter after the election for the new elected mayor. We show that this is the result of a decrease in tickets for traffic violations (rate and revenues) during election years. Our results are robustly driven by the municipal political cycle defined in different ways, and their magnitude and direction are not explained by the spillover effects between municipalities. Proximity to a national police station reduces the impact of local elections on injury rates.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
