The U.S. unemployment rate is a low 4.3% and headed lower. Yet inflation remains below 2%. Globalization, China, slow growth, and “transitory factors” such as cheaper cell phone plans help explain stubbornly low inflation. But they’re not the whole story.
Technology is another important—and often overlooked—challenge that central banks face in sustainably meeting their inflation targets. Our calculations reveal that technology’s use in producing U.S. GDP is increasing exponentially. And technology’s reach extends well beyond Silicon Valley. In 1997, U.S. workers used $0.08 of technology to make $1 of real GDP. Today we use $0.20, and that number is rising. Increasingly, the Federal Reserve is going toe to toe with Moore’s Law.
Moore's Law: A drag on inflation
Coined by Intel cofounder Gordon Moore, Moore’s Law has become shorthand for the diffusion of ever more powerful and cheaper technologies. We see it in consumer electronics—the smartphone that is twice as powerful and half as expensive as the one you replace, or the new TV that is flatter, sharper, and cheaper than last year’s model. These well-known, direct effects drag down measures of inflation for those products.
David Einhorn Buys Three New Stocks: These Are The Names And Theses (Q3 Letter)
David Einhorn's Greenlight Capital funds returned 5.9% in the third quarter of 2020, compared to a gain of 8.9% for the S&P 500 in the same period. This year has been particularly challenging for value investors. Growth stocks have surged as value has struggled. For Greenlight, one of Wall Street's most established value-focused investment funds, Read More
But Moore’s Law is about more than smartphones, TVs, and Amazon Prime. Its knock-on effects restrain the need for higher prices in every corner of the economy, not just in high-tech products. Prices are a markup over marginal costs, and in an increasingly digitized world, that marginal cost inches closer to zero. That’s the story told by our analysis of detailed industry data from the U.S. Bureau of Labor Statistics and the U.S. Bureau of Economic Analysis.
The growing reach of Moore's Law

To quantify how the increased utilization of technology is making it harder today to achieve 2% inflation, we identify the technology inputs used by each industry, from recreation and food services to law firms and utilities. We then compare the actual change in prices charged by each industry’s products and services (its Producer Price Index) with the change in a hypothetical index that excludes computer-based technology inputs.
The difference is striking. Since 2001, the declining prices of computer and electronic products, computer design and services, and other technology inputs have trimmed 0.5 percentage point per year from the prices that companies need to actually charge. If Moore’s Law didn’t exist, in other words, annualized inflation would have been 0.5 percentage point higher. Without Moore’s Law, core personal consumption expenditure (PCE) inflation would already be at 2%, and the Fed’s inflation target would have been achieved years ago. Interest rates would be higher.
Impact on industry
The impact has been most pronounced in technology-intensive industries, such as professional services and manufacturing. Moore’s Law helps explain how investment managers can now help clients diversify across global stock and bond markets at ever-lower expense ratios. It’s key to the longer-range, lower-cost electric cars rolling off assembly lines in Silicon Valley and Detroit. And it helps explain the slowing rates of inflation in the service fields of education, financial services, and retailing.
