We’re great at devising shiny, mainly software-driven bling that makes our lives more convenient in many ways. But we’re far less accomplished at reinventing health care, rethinking education, making food production and distribution more efficient, and, in general, turning our technical know-how loose on the largest sectors of the economy. Economists like to measure technological innovation as productivity growth—the impact of new stuff and new ideas on expanding the economy and making us richer. Over the last two decades, those numbers for the US have been dismal. Even as Silicon Valley and the high-tech industries boomed, productivity growth slowed. The last decade has been particularly disappointing, says John Van Reenen, an MIT economist who has recently written about the problem (pdf). He argues that innovation is the only way for an advanced country like the US to grow over the long run. There’s plenty of debate over the reasons behind sluggish productivity growth—but, Van Reenen says, there’s also ample evidence that a lack of business- and government-funded R&D is a big factor. His analysis is particularly relevant because as the US begins to recover from the covid-19 pandemic and restart businesses, we will be desperate for ways to create high-wage jobs and fuel economic growth. Even before the pandemic, Van Reenen proposed “a massive pool of R&D resources that are invested in areas where market failures are the most substantial, such as climate change.” Already, many are renewing calls for a green stimulus and greater investments in badly needed infrastructure. So yes, let’s build! But as we do, let’s keep in mind one of the most important failures revealed by covid-19: our diminished ability to innovate in areas that truly count, like health care and climate change. The pandemic could be the wake-up call the country needs to begin to address those problems.
