Abstract

fetched live from OpenAlex

It is well known that public or pooled insurance coverage can induce a form of ex-ante moral hazard: people make inefficiently low investments in self-protective activities.This paper points out another ex-ante moral hazard that arises through an induced innovation externality.This alternative mechanism, by contrast, causes people to devote an inefficiently high level of self-protection.As an empirical example of this externality, we analyze the innovation induced by the obesity epidemic.Obesity is associated with an increase in the incidence of many diseases.The induced innovation hypothesis is that an increase in the incidence of a disease will increase technological innovation specific to that disease.The empirical economics literature has produced substantial evidence in favor of the induced innovation hypothesis.We first estimate the associations between obesity and disease incidence.We then show that if these associations are causal and the pharmaceutical reward system is optimal the magnitude of the induced innovation externality of obesity roughly coincides with the Medicare-induced health insurance externality of obesity.The current Medicare subsidy for obesity therefore appears to be approximately optimal.We also show that the pattern of diseases for obese and normal weight individuals are similar enough that the induced innovation externality of obesity on normal weight individuals is positive as well.

Direct model labels (unvalidated)

Per-model category and study-design labels from the labeling rounds. They are machine output, unvalidated, and the disagreement between models ships as data. No study design here is MEDLINE-validated yet.

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.
