“Research and development conducted by private companies in the United States has grown enormously over the past four decades. We have substantially replaced the publicly funded science that drove our growth after World War II with private research efforts. Such private R&D has shown some impressive results, including high average returns for the corporate sector.
However, despite their enormous impact, these private R&D investments are much too small from a broader perspective. This is not a criticism of any individuals; rather, it is simply a feature of the system. Private companies do not capture the spillovers that their R&D efforts create for other corporations, so private sector executives in established firms underinvest in invention. The venture capital industry, which provides admirable support to some start-ups, is focused on fast-impact industries, such as information technology, and not generally on longer-run and capital-intensive investments like clean energy or new cell and gene therapies.
Leading entrepreneur-philanthropists get this. In recent years, there have been impressive investments in science funded by publicly minded individuals, including Eric Schmidt, Elon Musk, Paul Allen, Bill and Melinda Gates, Mark Zuckerberg, Michael Bloomberg, Jon Meade Huntsman Sr., Eli and Edythe Broad, David H. Koch, Laurene Powell Jobs, and others (including numerous private foundations). The good news is that these people, with a wide variety of political views on other matters, share the assessment that science—including basic research—is of fundamental importance for the future of the United States.
The less good news is that even the wealthiest people on the planet can barely move the needle relative to what the United States previously invested in science. America is, roughly speaking, a $20 trillion economy; 2 percent of our GDP is nearly $400 billion per year. Even the richest person in the world has a total stock of wealth of only around $100 billion—a mark broken in early 2018 by Jeff Bezos of Amazon, with Bill Gates and Warren Buffett in close pursuit. If the richest Americans put much of their wealth immediately into science, it would have some impact for a few years, but over the longer run, this would hardly move the needle. Publicly funded investment in research and development is the only “approach that could potentially return us to the days when technology-led growth lifted all boats.
However, we should be careful. Private failure is not enough to justify government intervention. Just because the private sector is underinvesting does not necessarily imply that the government will make the right investments.”
