It has long been recognised that innovation is unevenly distributed, but whether such technical progress may be the root cause of the rising income and wealth inequality in the US has been a matter of intense debate. This column studies the diffusion of 29 disruptive technologies across firms and labour markets in the US. It finds the locations where such technologies arise are highly concentrated but as they mature they gradually spread across space, particularly for lower-skilled hiring. Higher-skilled hiring is much slower to spread, with locations where initial discoveries were made retaining their leading positions among high-paying positions for decades. These technology hubs are more likely to arise in areas with universities and high-skilled labour pools.

An increasing number of goods and services employ AI-related technology. But for most consumers, determining which products use artificial intelligence remains a challenge. This column suggests that the spread of new technology may be delayed when information about it is difficult to communicate, and argues that standards governing artificial intelligence labelling can help to both educate consumers and promote the technology’s dissemination.

Recent debates about the global productivity slowdown point to a large and increasing productivity gap between firms operating at the global technological frontier and those trailing behind. This column analyses whether better access to bank credit can accelerate technological diffusion and narrow the productivity gap between leading and lagging firms. Using data from a large emerging market – Russia – it shows that while bank loans can encourage firms to adopt new technologies and become more productive, long-run benefits vary substantially across industries and regions.

This paper studies empirically technology diffusion across countries and over time, finding significant evidence that technology diffuses slower to locations that are farther away from adoption leaders. The authors document the significant role that geography plays in determining technology diffusion across countries.

Does the pattern of social connections between individuals matter for macroeconomic outcomes? This paper uses network analysis tools to explore how different social structures affect technology diffusion and thereby a country’s rate of technological progress.
