Hypothetical applied case

Innovation Incentives, Patents and R&D

Which policy rewards costly discovery without unnecessarily restricting access and follow-on research?

Teaching scenario, not a real procurement ยท Reviewed 10 October 2026

Scenario

A fictional public agency wants a low-cost diagnostic platform. Development is risky, marginal production cost is low, and follow-on researchers need access to a technical standard. Compare four instruments: patent exclusivity, a fixed research prize, an advance market commitment and a refundable R&D tax credit.

Boundary: No technology, firm, patent or budget described here is real. The page is a decision framework, not evidence that one instrument is generally superior.

Compare the instruments

InstrumentMain incentiveKey implementation risk
PatentTemporary exclusion can support expected returnsBreadth, duration, litigation and blocked follow-on use
PrizePayment for a specified resultFunder must define and verify success
Advance commitmentGuaranteed market if conditions are metEligibility, price and quantity design
Tax creditLowers eligible research costAdditionality and relabeling ordinary spending as R&D

Evidence questions

Additionality: How much research occurs because of the policy rather than receiving support after the fact?

Access: Who can use the resulting knowledge, at what price and under which license?

Spillovers: Patent citations, collaborations and follow-on products are partial proxies, not complete welfare measures.

Decision task

Your policy design

Select one instrument or a combination. Specify the success metric, payment rule, access condition, audit mechanism and failure case. Explain what evidence would change your recommendation.

Sources and indicator note

R&D expenditure as a share of GDP measures spending intensity, not research quality, innovation output, diffusion or causal policy impact. Sources checked 10 October 2026.
