CS2881R L9: Early Evidence on AI, Jobs, and Productivity
Lecture 9 of Harvard CS 2881R brought in OpenAI chief economist Ronnie Chatterji and Stanford's Bharat Chandar. Using ADP payroll data, Chandar showed that workers aged 22–25 in AI-exposed occupations saw a 16% relative employment decline after controlling for firm-level shocks, while experienced workers did not; the adjustment shows up in headcount, not yet in pay. Both speakers kept repeating that aggregate employment shows no mass displacement yet, and that exposure is not replacement. There are no slides: the material is the recording and the reading list.
