Director of the **Stanford Digital Economy Lab** and a leading scholar on the economics of artificial intelligence. He and his colleagues developed the [[prereq-productivity-j-curve|Productivity J-Curve]], which describes the macro-economic lag between adopting general-purpose technologies and visible productivity growth, noting that the required **organizational rewiring costs roughly 10× the investment in the technology itself**. The authors adapt his idea to the firm level as [[concept-micro-j-curve|the Micro Productivity J-Curve]]. Cited as an authoritative source, not an author of the article.
