"The Creativity Decline in US Patenting " (2022) Job Market Paper (Draft Coming Soon)

Slides

Abstract: I use the texts of patents to separate creative from derivative patents. I argue that the rise in patenting and a slowdown in productivity in recent years is explained by the falling share of creative patents. I show that only creative patents are associated with improvements in firm level productivity and market valuations. In an endogenous growth model, I show that ageing and decreasing government support for research and development explain about half of the decline in creativity and 40% of the slowdown in productivity.


Abstract: We identify novel technologies using textual analysis of patents, job postings, and earnings calls. Our approach enables us to document the diffusion of 29 disruptive technologies across firms and labor markets in the U.S. Four stylized facts emerge from our data. First, as technologies mature and the number of new jobs related to them grows, they gradually spread across space. While initial hiring is concentrated on high-skilled jobs, over time the mean skill level in new positions associated with the technologies declines, broadening the types of jobs that adopt a given technology. At the same time, the geographic diffusion of low-skilled positions is significantly faster than higher-skilled ones, so that the locations where initial discoveries were made retain their leading positions among high-paying positions for decades. Finally, such technology hubs are more likely to arise in areas with universities and high skilled labor pools.
