My colleague Michael Cannon has already [written](https://www.cato.org/blog/trump-attempts-price-controls-prescription-drugs) that the Department of Health and Human Services “does not have the power to ‘impose’ price controls on private pharmaceutical purchases.” The order also instructed federal agencies to investigate why European countries pay lower prices for drugs. Why do drug prices vary across countries? An [article](https://www.cato.org/regulation/fall-2024/are-drug-prices-abroad-too-low) in the Fall 2024 issue of *Regulation* offers some insight from economists. The knowledge embodied in pharmaceuticals is a global public good. The incentives are for all countries to avoid the fixed costs of drug development and clinical trials and pay only the marginal costs of producing a drug. The demand for health care increases with income and population, so the worst-case possibility is that the richest and largest country (i.e., the US) pays all the fixed costs of drug development, and all other countries free ride and pay only the marginal costs. The authors gathered data on sales revenue and compared the revenue to estimates of marginal cost to calculate each country’s contribution to the fixed costs of drug development. They conclude that a country’s GDP explains 83 percent of the variation in contributions across countries, and the effect of income is greater than proportional. A country with a 100 percent higher GDP contributes 129 percent more to pharmaceutical R&D. So, the US does contribute disproportionately to drug development costs. The rest of the world’s contribution is not zero but is less than would be predicted by income and population alone. The authors conclude: “Our findings indicate prospective gains from international cooperation–from formal or informal international agreements among high-income countries. If other wealthy countries agreed to contribute more to the global public good, they, and the world, would benefit.” ##### Related Tags [Health Care](https://www.cato.org/health-care) [![Creative Commons License](/build/cato_2020/images/creative-commons.svg)](http://creativecommons.org/licenses/by-nc-sa/4.0/) This work is licensed under a [Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License](https://creativecommons.org/licenses/by-nc-sa/4.0/).
