Most Favored Nation Drug Pricing

February 4, 2026

Key Findings

  • Half of survey respondents felt that most favored nation (MFN) drug pricing — a policy linking the prices of prescription drug prices in the U.S. to those paid in peer countries — would substantially reduce average net prices for branded drugs in the U.S. Another quarter were uncertain about the policy’s impact on prices. A number of respondents raised concerns about the feasibility of implementing MFN pricing and responses of manufacturers that could make such a policy less effective.
  • Most respondents did not feel that MFN pricing would substantially improve access to branded prescription drugs for patients with public or private forms of insurance, although there was considerable uncertainty. Several panelists noted that Medicaid programs already pay relatively low prices for branded drugs and that MFN prices may still be too high for uninsured individuals.
  • Panelists were mixed on whether MFN pricing would substantially reduce pharmaceutical innovation benefiting patients in the U.S. Thirty-eight percent agreed or strongly agreed that such a policy would reduce innovation, 28% disagreed or strongly disagreed, and 32% were uncertain. Several panelists suggested that the policy could lead to some decline in innovation, but that the impact depends on the magnitude of the decline in revenues for pharmaceutical companies, which itself is an uncertain outcome.

Survey Questions

Please note: our surveys will consistently use two modifiers to describe the size of an effect: “Substantial”: when an effect is large enough to meaningfully influence policy decisions, program implementation, or outcomes of interest “Measurable”: when the direction of an effect is clear, but the effect may not be sufficiently large to make much of a difference for a given policy, program, or outcome.

Response rate of 97% (60 out of 62 panelists responded, 1 panelist abstained)


The Trump Administration has expressed a desire to link US prescription drug prices to net prices paid in peer countries, a policy known as Most Favored Nation (MFN) drug pricing. An MFN pricing policy would require manufacturers of branded drugs to charge any payer or patient a price equal to or lower than the MFN price. This price would be defined as the second lowest manufacturer-reported net price (adjusted for Gross Domestic Product per capita) in peer countries.

Janet CurrieAgree6
Lesley CurtisDisagree8I expect manufacturers to respond by increasing prices outside of the US.  Potential for short-term decrease but not long term.
David CutlerAgree6I wonder what types of games companies may play — e.g., having different drugs in different countries.
Julie DonohueUncertain6It is not clear the administration has the legal authority to impose this absent legislation. Pharmaceutical manufacturers could respond to such a policy by raising prices elsewhere in the world.
Joseph DoyleAgree7
David DranoveDisagree9PBMs already achieve significant discounts. Any further discounts would be small.
Stacie DusetzinaStrongly disagree9Based on carve outs already made to most drug companies, very few branded drug products would be eligible for MFN prices. Current implementation focuses on Medicaid in those voluntary agreements and pricing is likely to be similar to MFN prices in that program. Even if there were not many loopholes, access to international reference prices has remained a problem with MFN like pricing agreements.

Elliott FisherNo opinion0
Richard FrankAgree7
Craig GarthwaiteUncertain10The real problem with any MFN policy for the United States will be the details and therefore it is really hard to figure out what the impact would be. The range of proposed MFN policies have ranged from entirely ineffective to quite stringent, and I’m not sure which of these we would be thinking about for such a question.
Darrell GaskinAgree7
Martin GaynorDisagree7Such an MFN requirement will almost certainly cause pharmaceutical prices outside the US to increase. It may lead to US prices declining somewhat, but given the size and importance of the US market pharma companies may reduce prices in the US little or not at all.
Sherry GliedAgree5
David GrabowskiStrongly Agree8
Jonathan GruberUncertain5
Vivian HoStrongly Agree6Branded drug companies are likely making significant profits on the lower prices they are charging in other countries. Given that, they ought to be willing to lower their prices in the U.S. if forced to do so. However, I wouldn’t put it beyond these companies to restrict supply of important medications, in an effort to force the U.S. to change policies.
Jason HockenberryAgree7
Haiden HuskampDisagree7
Benedic IppolitoUncertain10The U.S. market is at least 10-20 times larger than markets in reference countries in current MFN proposals (and larger than all combined). Firms will have a huge incentive to circumvent the policy, delay launches/increase prices in reference countries, making the effects uncertain.
Anupam JenaAbstained
Nancy KeatingUncertain5
Aaron KesselheimStrongly Agree7Certainly initially, but my confidence is diminished because the pharmaceutical industry will strategically respond to blunt the effect, which is why in contrast to MFN pricing, the right policy is broader US price negotiation.
Jonathan KolstadDisagree6
R Tamara KonetzkaUncertain7I’m fairly confident that the outcome is uncertain! It may reduce some prices, but there are a lot of ways that drug manufacturers may get around this issue or ensure the prices are not transparent (e.g. raising prices but offering rebates)
Rick KronickStrongly Agree7
Valerie LewisDid not answer
Nicole MaestasAgree8
Tom McGuireDisagree6
Ellen MearaAgree7Since we cannot see rebates, i’m less confident about the magnitude of price drops, but they surely would be lower.
Ateev MehrotraAgree9
David MeltzerStrongly Agree9
Joseph NewhouseStrongly Agree8
Sean NicholsonStrongly Agree9My response assumes that the policy passes (Congress) as described above and applies to all drugs.  By executive order or bully pulpit, the effect would likely occur only on a small subset of drugs and have a negligible effect on overall spending.
Steve ParenteAgree8
Stephen PatrickUncertain5
Harold PollackUncertain4This is an ambitious experiment, with  likely good and bad unanticipated consequences for patients, payers, drug manyufacturers, and patients around the world. I am concerned about consequences for patients in low-income nations, who require life-saving drugs.
Daniel PolskyAgree6
Ninez PonceDisagree7Hard to assess since plan that the public can evaluate is vague.
Thomas RiceAgree6
Meredith RosenthalAgree8This plan seems so infeasible I have trouble scoring it. I am certain that our brand name drug prices are the highest in the world so if we literally started paying the lowest prices it would have a big effect. And so it cannot possibly happen…maybe for a few products for a political win.
Joseph RossDisagree7While there may be measurable price decreases, they will not be substantial, and I think it is more likely that companies will use MFN as a pretense for raising prices in peer countries.
Brendan SalonerDisagree5
Kosali SimonAgree5
Jon SkinnerUncertain6
Ben SommersUncertain5the question is whether it would more benefit companies to cut their prices here or raise prices elsewhere
Neeraj SoodUncertain5I think firms can game the system by having high list prices in other countries and offering confidential rebates or discounts.

Question Two

MFN pricing would substantially improve access to branded prescription drugs for the following patient populations in the US (select all that apply)

NameVoteConfidenceComments
Margarita AlegriaNone of the above6
David AschCommercially insured, Medicaid, Medicare, Uninsured6

Melinda BuntinCommercially insured4
Michael F. CannonUninsured2
Lawrence CasalinoCommercially insured, Medicare4
Amitabh ChandraNone of the above7It is possible that MFN pricing could lower the out-of-pocket price that patients pay, and this would mostly affect the uninsured period. This part of it makes a lot of sense.
Lanhee J. ChenNone of the above5
Michael ChernewCommercially insured, Medicare, Uninsured5Depends how its implemented and how purchasers respond
Janet CurrieCommercially insured, Medicaid, Medicare, Uninsured6
Lesley CurtisMedicaid, Medicare8
David CutlerCommercially insured, Uninsured5
Julie DonohueUncertain0The impact of the policy is uncertain because the legality of a policy unilaterally adopted by the executive branch is uncertain.
Joseph DoyleNone of the above5The US already has by far the best access to medications, earlier than other countries due to the high price. Lower prices would increase access via health insurance, but it would have to be filtered through more generous drug coverage and there are few links in that chain.
David DranoveUninsured9
Stacie DusetzinaNone of the above9The only program in which most companies are expected to offer MFN pricing due to the voluntary agreements is in Medicaid. Unclear if prices will be reduced under MFN for that program and patients are shielded from the price in that program.
Jose EsarceDid not answer
Elliott FisherUncertain0
Richard FrankUncertain0How MFN affects out of pocket costs depends importantly on how it is implemented.
Craig GarthwaiteNone of the above6If we think about MFN pricing as being an effective policy that lowers the domestic price to some degree, then we are really thinking here, do we think that there is a large decrease in access from higher net prices.  I have not seen meaningful evidence that this is the case – nor am I convinced that we would see meaningful changes to cost sharing.
Darrell GaskinUncertain0I depends on whether the payer or the patient receives the benefit of the price reductions.
Martin GaynorNone of the above8I don’t expect a large decrease in US prices of branded pharmaceuticals, so I don’t expect increased access.
Sherry GliedNone of the above8
David GrabowskiCommercially insured, Medicaid, Medicare8
Jonathan GruberMedicaid, Medicare, Uninsured7
Vivian HoUncertain0Given time, drug companies would respond by raising prices of drugs worldwide. I don’t have the data or knowledge to predict which drugs would be affected the most.
Jason HockenberryMedicaid, Medicare, Uninsured5
Haiden HuskampNone of the above7
Benedic IppolitoUncertain0If a policy did materially change prices, the effects would be concentrated in Medicare and commercial. But price change is highly uncertain.
Anupam JenaAbstained
Nancy KeatingUncertain0It depends what “access to branded drugs” means? it may lower costs of existing drugs, but might also lead to less innovation and fewer branded drugs developed.
Aaron KesselheimCommercially insured, Medicare6It’s likely that initially lower prices would facilitate broader coverage of at least some brand-name drugs (ideally the ones with meaningful benefits for patients), but I’d feel more “confident” about that if anything similar to MFN pricing would be linked to requirements for such coverage.
Jonathan KolstadNone of the above5
R Tamara KonetzkaCommercially insured3Unlikely to affect Medicaid because prices are often lower already; unlikely to affect Medicare access after IRA changes because OOP costs already capped; prices may still be too high to affect access for uninsured.
Rick KronickUninsured6
Valerie LewisDid not answer
Nicole MaestasCommercially insured, Medicaid, Medicare, Uninsured7
Tom McGuireNone of the above7
Ellen MearaUncertain0Since we don’t see rebates among insured groups and even a reduced price may be out of reach for many uninsured patients, I’m uncertain of the access change.
Ateev MehrotraMedicaid, Uninsured9
David MeltzerCommercially insured, Medicaid, Medicare8
Joseph NewhouseNone of the above6Price may still be too high for the uninsured. Most gains will accrue to payers.
Sean NicholsonUninsured8
Steve ParenteCommercially insured, Medicare, Uninsured7
Stephen PatrickUncertain0
Harold PollackMedicaid, Medicare3
Daniel PolskyNone of the above7Price reductions may have a greater impact on the cost of insurance than on access to drugs.  And prices still unaffordable for uninsured.
Ninez PonceUncertain0
Thomas RiceCommercially insured, Medicare, Uninsured6
Meredith RosenthalMedicaid, Uninsured6For the uninsured, these lower prices could make a difference — not for the poorest of this group but at the higher end. In Medicaid there would be some products that are off formulary now but could be covered if prices were much lower.
Joseph RossNone of the above9I think that with MFN, drug prices are likely to remain high and out-of-pocket costs will remain approximately the same for insured individuals. Lost from the discussion thus far is that many high-cost drugs are not considered beneficial enough for peer nations to provide coverage, so if there is no “peer price”, there is no MFN price for the U.S. (and we will continue to pay wholly unjustified high prices).
Brendan SalonerUninsured5
Kosali SimonCommercially insured6

Joseph DoyleAgree4This is a crucial parameter and there is considerable uncertainty around it.
David DranoveDisagree9If the pricing impact is small, the research impact will be small
Stacie DusetzinaDisagree7If operationalized broadly (not in the way that it is presumably going to be operationalized), it could have some impact on drug innovation. Ideally, however, prices in the US would be more aligned with value and it could improve the investments in higher value (rather than lower value drugs).
Jose EsarceDid not answer
Elliott FisherNo opinion0I wish I had sufficient knowledge of this topic to be able to give useful responses
Richard FrankUncertain3Again, it depends on how the MFN prices are used. If a multiplier to MFN is used (like in HR 3), it would have less dramatic revenue impacts than a straight application of say a lowest international reference price among wealthy OECD countries.
Craig GarthwaiteAgree7Again, I am assuming we are talking about a policy that lowers revenues here (which we don’t know would happen from an MFN).  I would also quibble a bit here with the framing of “US patients,” as it would reduce innovation that would otherwise be a benefit for all patients.
Darrell GaskinDisagree7Current pricing encourages and rewards modest innovations.
Martin GaynorUncertain6If pharma companies’ expected profits from new drugs falls substantially under the MFN policy, then I’d expect to see less innovation, but it’s very unclear if their profits will fall so much that innovation becomes much less profitable.
Sherry GliedAgree5
David GrabowskiStrongly Agree9
Jonathan GruberUncertain10Depends on how the revenues are spent – in a vacuum it will lower innovation but if the revenues are used for NIH innovation will go up.
Vivian HoUncertain10There should still be substantial returns to development of novel medications that improve patient health more than existing alternatives.
Jason HockenberryAgree7
Haiden HuskampAgree7
Benedic IppolitoUncertain3The relationship between revenues and investments is clear, but the effect on net revenues is too unclear.
Anupam JenaAbstained
Nancy KeatingAgree5
Aaron KesselheimStrongly disagree10
Jonathan KolstadStrongly Agree9
R Tamara KonetzkaDisagree5Incentives for innovation are important but current prices could likely come down substantially without large reduction in innovation. (Would prefer other support for innovation such as direct support of research rather than excessive prices.)
Rick KronickUncertain4
Valerie LewisDid not answer
Nicole MaestasAgree10
Tom McGuireDisagree7
Ellen MearaAgree5Losing out on the upper tail pricing of branded drugs in US markets will discourage innovation with certainty. The magnitude is less clear.
Ateev MehrotraAgree7
David MeltzerUncertain7
Joseph NewhouseAgree8High value drugs will still be brought to market as will losers in an innovation race but there will be some reduction.
Sean NicholsonStrongly Agree9
Steve ParenteUncertain7
Stephen PatrickAgree7
Harold PollackUncertain3
Daniel PolskyDisagree5It may end up rewarding innovation in areas that need innovation rather than areas where pricing is most profitable.  The direct evidence on this question is not that strong.
Ninez PonceUncertain8
Thomas RiceUncertain7
Meredith RosenthalUncertain5This is so hard to say. It would surely reduce innovation by some amount. But whether that is substantial or not is less certain. And also it would reduce some “innovation” that is welfare reducing — new line extensions with little benefit that keep spending high.
Joseph RossStrongly disagree8I do not think MFN pricing will substantially affect pharmaceutical company revenue, nor their R&D investments.
Brendan SalonerDisagree7
Kosali SimonAgree6
Jon SkinnerUncertain1
Ben SommersUncertain5
Neeraj SoodAgree5I think this affects innovation as it creates a chilling effect that pharma price regulation is happening and even if this policy is not binding other policies might be binding.
