The Nugget
- Intellectual property provisions in trade treaties often lead to higher medicine prices and decreased consumer welfare, adversely affecting access in low and middle-income countries. The degree of impact varies based on whether the evaluation is ex-ante (predictive) or ex-post (empirical).
Make it stick
- 📈 Higher prices and decreased access to medicines are consistently observed outcomes when trade agreements impose stricter intellectual property rights.
- 💊 TRIPS-plus provisions, which include additional patent protections, tend to exacerbate price hikes, limiting the availability of both branded and generic medications.
- 🧮 Ex-ante studies tend to predict significant price increases (50% to 600%) compared to more moderate empirical findings (3% to 50%) from ex-post studies.
- 🌍 The effect on medicine access is multifactorial, influenced by local policies, GDP levels, and the existing healthcare ecosystem of the country.
Key insights
Impacts of Intellectual Property Provisions
- Increased Prices: Both ex-ante studies predict sharp increases in medicine prices due to stronger IP regulations, while ex-post findings suggest moderate price inflation.
- Consumer Welfare: The imposition of IP protections generally results in decreased consumer welfare, as higher prices lead to reduced medication affordability and availability.
- Variable Effects: The effects of IP provisions vary by country, impacted by existing healthcare structures and the strength of local generics markets.
Types of Studies Reviewed
- Ex-ante Studies (Predictive): Focus on structural modeling and simulations to estimate potential impacts on access based on hypothetical scenarios.
- Ex-post Studies (Empirical): Utilize actual historical data and econometric methods to analyze the real-world effects of IP policy changes post-implementation.
- Mixed Findings: A mix of results indicates complexities in how specific IP measures affect different medicines and various countries.
Research Gaps and Future Directions
- Need for More Studies: A clear requirement for further empirical research exists to better understand how various IP measures impact different medicines and healthcare outcomes.
- Exploration of Mechanisms: There is insufficient understanding of the mechanisms through which IP provisions affect medicine access, necessitating targeted studies.
- Cross-Country Variation: Future research should explore how IP impacts differ among low and middle-income countries, considering their unique economic and healthcare contexts.
Key quotes
- "Both ex ante and ex post methods report, for the most part, an increase in price and a decrease in consumer welfare with imposition of intellectual property protection."
- "Changes in intellectual property policy due to the implementation of trade agreements affect price, medicines expenditure and sales, consumer welfare, and ultimately the affordability of medicines."
- "The impact of IP provisions manifests through the healthcare/pharmaceutical ecosystem, highlighting the necessity for integrative approaches."
- "Existing generic producers are often 'grandfathered' and continue to produce even after patent enforcement, leading to less severe price hikes than predicted."
- "We are unable... to unpack the main IP drivers that impact access to medicines."
