Abstract

fetched live from OpenAlex

This paper examines whether the composition of medical research responds to changes in disease incidence and research opportunities.The paper also provides new evidence on induced pharmaceutical innovation.In both cases we use the change in the demographic structure of the market (measured by age structure and obesity prevalence) to test the induced innovation hypothesis.Technological opportunity is calculated from estimates of structural productivity parameters.The extent of inventive activity is measured from the MEDLINE database on 16 million biomedical publications.We match these data with data on disease incidence.We show that medical research responds to changes in disease incidence and research opportunities.We also find that pharmaceutical innovation responds to aging-and obesity-induced changes in potential market size.

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.

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.
