Overview
- A new analysis by Stripe economist Ernie Tedeschi, reported late in the week, finds U.S. output per hour rose about 2.5% over the past year while deeper efficiency measures did not accelerate.
- Total factor productivity, which adjusts for both labor and capital and signals true technological efficiency, has remained near zero in some estimates even as headline labor productivity climbed.
- Tedeschi and other analysts say the measured boost mostly comes from higher capital utilization such as longer factory runs, fuller server and GPU use, and higher occupancy in existing assets.
- Studies show AI improves specific tasks for some workers, but cross‑industry data indicate those micro gains have not yet aggregated into broad, sustained productivity growth.
- Economists warn adoption bottlenecks and organizational frictions could delay wider AI payoffs and say the current pattern means AI may matter more in the future but is not the main driver today.
