Every year, millions of people die from preventable and treatable diseases, especially in poor countries. In many cases, lifesaving medicines can be cheaply mass produced, but are sold at prices that block access to those who need them. Many die simply because there are no cures or vaccines, because so little of the world’s valuable research talent and limited resources are devoted to addressing the diseases of the poor.
This state of affairs represents a failure of economics and law that urgently needs to be corrected. The good news is that there are now opportunities for change, most promisingly through an international effort headed by the WHO that would begin to fix the broken intellectual property regime that is holding back the development and availability of cheap drugs.
Two main problems limit the availability of medicines today. One is that they are very costly; or, more accurately, the price charged for them is very high, though the cost of producing them is but a fraction of that amount. Second, drug development is geared toward maximizing profit, not social benefit, which skews efforts directed at the creation of medicines that are essential to human welfare. Because the poor have so little money to spend, drug companies, under current arrangements, have little incentive to do research on the diseases that afflict them.
It does not have to be this way. Drug companies say that high prices are necessary to fund research and development. However, in the US, it is actually the government that finances most health-related research and development — directly, through public support (National Institutes of Health, National Science Foundation), and indirectly, through public purchases of medicine, both in the Medicare and Medicaid programs. Even the part that is not government-financed is not a conventional market; most individuals’ purchases of prescription medicines are covered by insurance.
Government finances healthcare research because improved medicines are a public good. The resulting knowledge benefits everyone by stopping epidemics and limiting the economic and human toll of widespread illness. Efficiency requires sharing research as widely as possible as soon as it is available. Thomas Jefferson compared knowledge to candles: When one is used to light another, it does not diminish the light of the first. On the contrary, everything becomes brighter.
Yet, in the US and most of the world, drug prices are still exorbitant and the spread of knowledge is tightly limited. That is because we have created a patent system that gives innovators a temporary monopoly over what they create, which encourages them to hoard their knowledge, lest they help a competitor.
While this system does provide incentives for certain kinds of research by making innovation profitable, it allows drug companies to drive up prices, and the incentives do not necessarily correspond to social returns. In the healthcare sector, it may be more profitable to devote research to a “me-too” drug than to the development of a treatment that really makes a difference. The patent system may even have adverse effects on innovation, because, while the most important input into any research is prior ideas, the patent system encourages secrecy.
A solution to both high prices and misdirected research is to replace the current model with a government-supported prize fund. With a prize system, innovators are rewarded for new knowledge, but they do not retain a monopoly on its use. That way, the power of competitive markets can ensure that, once a drug is developed, it is made available at the lowest possible price — not at an inflated monopoly price.
Fortunately, several US lawmakers are taking a strong interest in this approach. The “Prize Fund for HIV/AIDS Act,” a bill introduced by US Senator Bernie Sanders, is just such an initiative. His bill also contains an important provision aimed at encouraging open-source research, which would move the current research model away from secrecy toward sharing.
However, globally, our innovation system needs much bigger changes. The WHO’s efforts to encourage broad reforms at the international level are crucial. This spring, the WHO released a report that recommends solutions similar to those proposed in the US Senate bill, but on a global level.
Importantly, the report, Research and Development to Meet Health Needs in Developing Countries, recommends a comprehensive approach, including mandatory funding contributions from governments for research on developing countries’ health needs; international coordination of healthcare priorities and implementation; and a global observatory that would monitor where needs are greatest. Later this month, the international community will have a chance to begin implementing these ideas at the WHO World Health Assembly — a moment of hope for public health around the world.
Reforming our innovation system is not just a matter of economics. It is, in many cases, a matter of life and death. It is therefore essential to delink research and development incentives from drug prices and to promote greater sharing of scientific knowledge.
For the US, the Sanders bill marks important progress. For the world, the WHO’s recommendations represent a once-in-a--generation opportunity to remedy a long-standing and egregious inequity in healthcare, and, more broadly, to set a model for governance of global public goods befitting an era of globalization. We cannot afford to let this opportunity pass us by.

In their recent op-ed “Trump Should Rein In Taiwan” in Foreign Policy magazine, Christopher Chivvis and Stephen Wertheim argued that the US should pressure President William Lai (賴清德) to “tone it down” to de-escalate tensions in the Taiwan Strait — as if Taiwan’s words are more of a threat to peace than Beijing’s actions. It is an old argument dressed up in new concern: that Washington must rein in Taipei to avoid war. However, this narrative gets it backward. Taiwan is not the problem; China is. Calls for a so-called “grand bargain” with Beijing — where the US pressures Taiwan into concessions
The term “assassin’s mace” originates from Chinese folklore, describing a concealed weapon used by a weaker hero to defeat a stronger adversary with an unexpected strike. In more general military parlance, the concept refers to an asymmetric capability that targets a critical vulnerability of an adversary. China has found its modern equivalent of the assassin’s mace with its high-altitude electromagnetic pulse (HEMP) weapons, which are nuclear warheads detonated at a high altitude, emitting intense electromagnetic radiation capable of disabling and destroying electronics. An assassin’s mace weapon possesses two essential characteristics: strategic surprise and the ability to neutralize a core dependency.
Chinese President and Chinese Communist Party (CCP) Chairman Xi Jinping (習近平) said in a politburo speech late last month that his party must protect the “bottom line” to prevent systemic threats. The tone of his address was grave, revealing deep anxieties about China’s current state of affairs. Essentially, what he worries most about is systemic threats to China’s normal development as a country. The US-China trade war has turned white hot: China’s export orders have plummeted, Chinese firms and enterprises are shutting up shop, and local debt risks are mounting daily, causing China’s economy to flag externally and hemorrhage internally. China’s
During the “426 rally” organized by the Chinese Nationalist Party (KMT) and the Taiwan People’s Party under the slogan “fight green communism, resist dictatorship,” leaders from the two opposition parties framed it as a battle against an allegedly authoritarian administration led by President William Lai (賴清德). While criticism of the government can be a healthy expression of a vibrant, pluralistic society, and protests are quite common in Taiwan, the discourse of the 426 rally nonetheless betrayed troubling signs of collective amnesia. Specifically, the KMT, which imposed 38 years of martial law in Taiwan from 1949 to 1987, has never fully faced its
