The escalating cost of innovative medicines in the United States has become a pressing issue, as Americans pay significantly more than other developed nations. The Trump administration sought to address this imbalance through the implementation of Most-Favored-Nation (MFN) pricing strategies, which aimed to align U.S. drug prices with those of comparable countries. However, this initiative faced resistance and was ultimately blocked by the Biden administration. While MFN pricing presents an appealing solution at first glance, it harbors several critical flaws that could undermine its effectiveness. These include the potential for manipulation by pharmaceutical companies, an inability to alter fundamental global market economics, and the relinquishing of pricing control to foreign governments. This article explores these challenges and proposes alternative solutions, such as adopting value-based pricing models, fostering innovation incentives, and ensuring equitable access to life-saving medications.

Among the concerns surrounding MFN pricing is its susceptibility to gaming. Pharmaceutical firms and their international clients might collude to create the illusion of higher overseas prices through confidential rebate agreements. This practice would maintain low net prices while deceiving the U.S. government into believing otherwise. Furthermore, compelling drug manufacturers to disclose these rebates could violate foreign confidentiality laws, rendering enforcement impractical. Another drawback lies in the basic economic structure of the global pharmaceutical market. Research conducted at the USC Schaeffer Center reveals that approximately 70% of worldwide pharmaceutical profits stem from the U.S. market. Consequently, if companies face significant reductions in their U.S. pricing, they may withdraw from less profitable overseas markets, leaving American consumers with unchanged prices but diminished prospects for future innovation.

In addition to these economic implications, MFN pricing entails ceding pricing authority to foreign governments. Western nations often adopt different valuation standards for new medicines compared to the United States. For instance, the British National Health Service assigns much lower values to health improvements than even conservative American assessments suggest. Other developed countries are not averse to denying their citizens access to drugs priced beyond their artificially low thresholds. Instead of importing shortsighted foreign pricing practices, the U.S. should advocate for rational, forward-thinking pricing abroad. Establishing a system leveraging advanced economic methods for computing value could limit U.S. prices to reasonable estimates while preserving appropriate incentives for medical innovation.

This proposed system could incorporate outcomes-based pricing agreements, where prices fluctuate according to drug performance. Anti-obesity medication serves as a prime example, offering the potential for extended, healthier lives but raising questions about sustained weight loss over time. A success fee structure could be implemented, accumulating payments for each period during which weight loss is maintained and refunding all costs if the drug proves ineffective. Companies embracing this arrangement upon drug launch could agree not to accept any overseas price below the U.S. price, adjusted for national income differences. In return, they might receive incentives like reduced copays in Medicare or support from the U.S. government in negotiating fair prices in foreign markets.

There are valid reasons why Americans should pay more for earlier access to novel medications than their trading partners. As the largest pharmaceutical market globally, the U.S. uniquely benefits from new medicines, often recouping additional costs through longer, healthier lives. Nonetheless, current international pricing practices necessitate reform to alleviate political tensions. Only through American price leadership can both consumer needs and sustained innovation be effectively balanced moving forward.
