Study | Data / period | Main finding | Job impact |
Brynjolfsson, Chandar & Chen — “Canaries in the Coal Mine” (Stanford, revised 2026) | ADP payroll data, millions of workers, through June 2026 | No widespread economy-wide displacement, but employment of 22–25-year-olds in highly AI-exposed occupations is 19% below the counterfactual. Experienced workers show no comparable gap. | Strong evidence for the hiring channel. The authors say the adjustment occurs primarily through reduced hiring of young workers rather than increased separations. (Stanford Digital Economy Lab) |
Hosseini Maasoum & Lichtinger — “Generative AI as Seniority-Biased Technological Change” (Harvard, 2026 revision) | 65 million résumés, 280,000+ firms | Junior employment falls following GenAI adoption, particularly in highly exposed occupations; senior employment is largely unchanged. | Decline is driven primarily by slower hiring rather than increased separations. (SSRN) |
Tucker — “You're (not) Hired” (U.S. Census, 2026) | Matched employer-employee administrative data | Early-career employment in the most AI-exposed industry/state cells fell 12% over 10 quarters after ChatGPT. | The paper finds the decline in employment was primarily caused by a large decrease in hiring. This is perhaps the clearest administrative-data evidence of the mechanism. (Census.gov) |
Liu, Wang & Yu — “Labor Demand in the Shadow of Generative AI” (World Bank, 2026 revision) | 285 million U.S. online job postings, 2018–2025 | Postings for occupations highly vulnerable to AI substitution fell 9% relative to less-vulnerable occupations, with the differential reaching 15% by the third year. | Direct evidence of reduced labor demand, rather than layoffs. Particularly important because it examines vacancies at enormous scale. (SSRN) |
Audoly, Guerin & Topa — New York Fed, “Do Job Postings Show Early Labor-Market Effects of AI?” (2026) | U.S. Lightcast postings | Overall hiring has slowed, but they find little evidence of a distinct AI-driven decline in postings for AI-exposed occupations. | Important counterweight: the aggregate slowdown in postings cannot confidently be attributed to AI. (Liberty Street Economics) |
Federal Reserve Board — “AI Adoption and Firms' Job-Posting Behavior” (2026) | Firm/industry AI adoption + job postings | No evidence that firms or industries with greater AI adoption have reduced total job postings. | Suggests that if AI is eliminating some positions, firms may be switching hiring toward other jobs, rather than simply reducing total hiring. (Federal Reserve) |
Gimbel, Kendall & Nunn — Yale Budget Lab (2026) | Monthly CPS employment/wage data | After controlling for differences between exposed and unexposed occupations, they find no statistically or economically significant aggregate employment or wage effect. | Again, little evidence of broad existing-job destruction. The effects may be concentrated in particular populations. (The Budget Lab) |
Humlum & Vestergaard — “Still Waters, Rapid Currents” (NBER, 2025/26) | Danish administrative records + AI adoption surveys | No detectable effect on earnings or hours, even among early adopters and highly exposed workers. But substantial task restructuring and occupational switching occurred. | Little evidence of job elimination so far. Firms appear initially to be reorganizing work rather than cutting employment. (National Bureau of Economic Research) |
Chandar — “Tracking Employment Changes in AI-Exposed Jobs” (2025) | U.S. CPS, Q4 2022–Q1 2025 | No substantial aggregate employment/earnings difference in highly exposed occupations, although software and customer-service occupations diverge. | Overall employment effects small; evidence of localized employment declines, not economy-wide displacement. (SSRN) |
Frank et al. / related job-posting research summarized by Stanford | U.S. job postings | Several studies find greater declines in postings in AI-exposed occupations. But some declines began before ChatGPT and correlate with interest rates/remote work. | Supports reduced postings, but attribution to GenAI is contested. (Brookings) |
“Winners and losers of generative AI” (JEBO, 2025) | Online freelance marketplace | About 10% of postings were judged substitutable by GenAI; demand for those skill clusters fell as much as 50% in short-term roles. | Strong evidence of demand substitution in particular tasks, although aggregate freelance demand did not fall. (ScienceDirect) |
PwC 2025 AI Jobs Barometer | Lightcast job postings, 2019–2024 | U.S. occupations with greater GenAI exposure experienced substantially slower job-posting growth: roughly 2% vs. 20% for less-exposed occupations. | Strong descriptive evidence of slower demand growth, though not necessarily causal evidence of AI. (PwC) |
