Abstract

fetched live from OpenAlex

Dans cette étude expérimentale, nous examinons les déterminants des contributions volontaires visant à réduire les pertes attendues associées à des désastres naturels ou des accidents industriels majeurs. Les sujets doivent allouer leurs jetons entre un investissement privé et un investissement public. Ce dernier investissement réduit, pour tous les membres de l'équipe, la probabilité d'une perte. La perte attendue sans investissement public est constante pour tous les traitements, mais la probabilité d'une perte et la dotation initiale des sujets varie selon les traitements. Dans certains cas, les sujets jouent en situation d'information incomplète (ambiguïté). Les analyses non-paramétriques et paramétriques des données donnent des résultats cohérents avec les études classiques sur les contributions volontaires dans les biens publics. En retenant l'hypothèse que les sujets sont neutres au risque, nous observons un comportement qui rejette, pour tous les traitements, la prédiction de l'équilibre de Nash de zéro contribution dans l'investissement public. L'occurrence d'une perte accroît dans la période suivante la probabilité de jouer Nash et réduit le niveau de contribution dans l'investissement public (gambler's fallacy). Cette situation rend plus difficile la mobilisation des personnes après un désastre naturel.

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.
