The Ok-shaped financial system has dominated discourse recently, however the J-curve is getting into the chat too amid debate over AI’s affect on productiveness.
The curve refers to the concept general-purpose applied sciences like AI don’t produce rapid advantages. As an alternative, huge funding comes first, obscuring early positive aspects. It’s solely after this preliminary dip that productiveness actually takes off, ensuing within the J form. However for some, it’s not clear but that the transformation is going on.
Apollo Chief Economist Torsten Slok quipped that “AI is everywhere except in the incoming macroeconomic data,” recalling Robert Solow’s well-known quote in regards to the PC revolution. Slok added that employment, productiveness and inflation stats are nonetheless not displaying indicators of the brand new expertise. In the meantime, revenue margins and earnings forecasts for S&P 500 firms outdoors of the “Magnificent 7” additionally lack proof of AI at work.
“Maybe there is a J‑curve effect for AI, where it takes time for AI to show up in the macro data. Maybe not,” he wrote in a notice on Saturday.
However in a Monetary Occasions op-ed titled “The AI productivity take-off is finally visible,” economist Erik Brynjolfsson pointed to the most recent jobs report from the Bureau of Labor Statistics as proof that the “fog may finally be lifting.”
Wednesday’s report revised the studying on 2025 job positive aspects to simply 181,000, down from an preliminary print of 584,000 and from 2024’s acquire of 1.46 million.
Provided that the financial system continued to broaden at a wholesome tempo whereas including so few staff final 12 months, with fourth-quarter GDP monitoring up 3.7%, that implies a surge in productiveness.
Brynjolfsson mentioned his personal evaluation suggests U.S. productiveness jumped roughly 2.7% in 2025—practically double the 1.4% annual common seen over the previous decade.
“The updated 2025 US data suggests we are now transitioning out of this investment phase into a harvest phase where those earlier efforts begin to manifest as measurable output,” he mentioned.
Brynjolfsson, who’s director of Stanford College’s Digital Financial system Lab and has been finding out AI since earlier than ChatGPT surprised the world, printed a first-of-its-kind examine final 12 months that confirmed AI was hitting entry-level staff disproportionately, particularly these ages 22 to 25 in extremely AI-exposed professions.
He cautioned that a number of extra intervals of sustained development are want to verify a long-term pattern in productiveness, including that geopolitical or financial snafus may offset advances.
However whereas many companies are nonetheless utilizing AI in minimal methods, Brynjolfsson mentioned he’s discovered “a small cohort of power users” who’re automating end-to-end workstreams with AI brokers, finishing duties in hours as an alternative of weeks.
“We are transitioning from an era of AI experimentation to one of structural utility,” he wrote within the FT. “We must now focus on understanding its precise mechanics. The productivity revival is not just an indicator of the power of AI. It is a wake-up call to focus on the coming economic transformation.”
When trying on the info and communication expertise (ICT) industries, others additionally see clear indicators that AI is boosting productiveness.
Stephen Brown, chief deputy North America economist at Capital Economics, mentioned in a notice earlier this month that ICT output in the course of the third quarter rose regardless of a drop in employment.
Whereas earlier payroll cuts had been possible on account of overhiring within the pandemic, reductions have continued at the same time as ICT sectors have boomed, he added.
“All this implies that AI is making a large contribution to productivity growth,” Brown declared.
