Representative high‑value works (evidence & extract)

• Switching costs, price sensitivity and health plan choice (Journal of Health Economics, 2002) — empirical econometric study of consumer response to premium changes and switching costs; widely cited in health plan choice literature and policy analyses. Switching costs (JHE, 2002)
• Private Cost Containment (NEJM, 1988) — analysis of utilization review (UR) programs' effects on hospital use and costs from claims data across employer groups; influential in policy debates. Private Cost Containment (NEJM, 1988)
• Health care economics (book, 1979, later editions) — textbook framing demand, supply, role of government and institutional economics in health care; frequently used and cited as a teaching/reference source. Health care economics (book, 1979)

Qualitative scientific assessment

Strengths:

• Long trajectory of publications spanning empirical econometrics and policy‑oriented analyses, with multiple field‑defining papers in peer‑reviewed high‑visibility outlets (Journal of Health Economics, NEJM, Health Affairs) indicating strong domain influence.
• Use of administrative/claims data and natural experiments (e.g., premium policy changes) to estimate realistic policy‑relevant parameters (price elasticities, switching costs), which increases applied value.
• High citation counts for select works (book cited ≈460; key articles cited dozens–hundreds of times), consistent with sustained impact in health‑economics policy debates.

Limitations / blindspots:

• Many influential results derive from observational administrative data—while econometric controls and natural experiments are used, residual confounding and limited external validity remain possible.
• Topical focus is mainly health economics/health policy (utilization review, insurance market behavior); fewer basic biomedical or mechanistic health/clinical science contributions.
• Some outputs are books and policy pieces (high influence on thought/education) rather than experimental/clinical randomized evidence; interpretive caution is needed when translating policy‑level findings into clinical expectations.

Bottom‑line conclusion (evidence‑weighted)

Paul J. Feldstein is a solid, influential health‑economics scholar whose empirical work on utilization review, health plan choice, and private cost containment has had measurable policy influence and citation traction; his research methods are standard for applied health economics (econometric analysis of administrative/natural‑experiment data) and produce useful policy estimates, but interpretation should account for observational designs and market/context dependence.

What would change this appraisal: access to independent replication datasets showing robustness (or lack thereof) of core empirical estimates; preregistered reanalysis; or stronger causal designs (randomized rollouts) that confirm or overturn observational estimates.
