# AI productivity gains enable GDP-healthspan decoupling because gains are concentrated in information services and professional activities while chronic disease burden concentrates in manufacturing construction and lower-skill services

The Kansas City Fed found that productivity gains in the gen-AI era are 'MORE CONCENTRATED than the pre-pandemic era' with a distribution curve that 'stays below zero for much of the distribution and then climbs sharply near the right tail.' Gains 'appear driven by specific slices of information services and business-facing professional activities, rather than being evenly spread.' This concentration pattern allows the US to post 2.7% aggregate productivity growth in 2025 (nearly double the 1.4% decade average) while the chronic disease burden remains concentrated in sectors seeing minimal AI benefit. High-skill services and finance achieved ~0.8% gains in 2025 with 2%+ expected in 2026, while low-skill services, manufacturing, and construction saw only ~0.4% gains in 2025 with ~0.8% expected in 2026. The doubling for lower-skill sectors is real but from a much lower base. This creates a GDP/healthspan decoupling mechanism: the 2.7% productivity growth co-exists with declining population health metrics because the $575B/year chronic disease productivity burden (Session 32) concentrates in the non-AI-exposed sectors. The right-tail distribution means aggregate statistics look healthy while the median worker in chronic-disease-concentrated sectors sees minimal AI benefit. The KC Fed notes an 'AI J-curve' in manufacturing where early adoption slows productivity before delivering gains, suggesting manufacturing AI adoption is real but not yet showing productivity benefits. This decoupling can persist until the chronic disease burden becomes a binding constraint even on AI-exposed sectors.


## Challenging Evidence

**Source:** Yotzov, Barrero, Bloom et al., NBER WP 34836 (Feb 2026)

NBER WP 34836 shows 80% of companies report no AI productivity gains, and the 20% seeing gains are concentrated in high-skill/high-income sectors. This directly contradicts the decoupling hypothesis because chronic disease productivity burden ($575B/year per IBI) falls on lower-skill workers who are NOT experiencing AI productivity gains. The distributions are non-overlapping, preventing AI from compensating for health decline.
