Stanford Digital Economy Lab Tracks Generative AI Labor Market Divergence
Generative artificial intelligence is shifting employment patterns across age groups and skill sets, according to a revised working paper from the Stanford Digital Economy Lab. The research highlights a widening employment divergence through mid-2026, noting that young workers in jobs dependent on codified knowledge face declining employment rates, while experienced workers in tacit-knowledge roles see gains.
The revised paper extends data collection through mid-2026 and introduces new evidence regarding the mechanisms driving these labor market shifts. Researchers found that employment has dropped among young workers in occupations relying heavily on codified knowledge—defined as formal, standardized information taught through textbooks or written procedures. Conversely, employment has increased for experienced workers in occupations utilizing tacit knowledge acquired through practice and mentorship.
Codified Knowledge Displaces Young Workers
The data suggests that generative artificial intelligence effectively reproduces and applies information already encoded in digital formats, while experience-based knowledge remains difficult to replicate. This dynamic creates a clear age gradient in occupations where observed AI usage is automating rather than complementary. The study also indicates that women face greater AI exposure on average, a demographic divergence researchers intend to monitor as new data emerges.
Alternative explanations, such as interest rate fluctuations and remote work trends, do not fully account for these patterns. The employment divergence continued to widen through mid-2026, well after interest rates peaked. By November 2022, the relative position of exposed young workers had already returned to roughly its pre-pandemic level, making subsequent declines a distinct downward movement rather than a pandemic-era correction.
Data Gaps Complicate Proof of AI Labor Disruption
Despite these findings, the authors emphasize that the study does not provide definitive proof of AI-driven labor disruption. Gaps between more- and less-exposed young workers narrow when researchers control for education levels, and certain differential trends were visible before the widespread adoption of generative AI.
Estimated gaps are larger in the ADP analysis sample than in national survey benchmarks. Adjustments to the data pipeline produced directionally consistent results that remain sensitive to specific analytical choices, making it unclear whether the patterns generalize to the broader economy.
Monthly Economic Indicators Track Future Shifts
To address ongoing uncertainties, the Stanford Digital Economy Lab launched the AI Economic Indicators initiative to provide high-frequency economic measurements. As part of this effort, the lab’s Canaries Dashboard will update key results from the research paper every month to track whether these employment shifts accelerate, stabilize, or spread across additional sectors.
