# AI, Productivity, and Labor Markets: A Review of the Empirical Evidence

Tier B (Useful, limited): International Center for Law & Economics issue brief by Eric Fruits and Kristian Stout; a competent, well-referenced literature review with an annotated bibliography, but secondary and written toward a deregulatory policy conclusion.

Summary based on the full text.

## In short

A February 2026 review of the empirical work on AI, productivity and jobs. Its reading: experiments show large task-level gains, especially for less experienced staff; aggregate labour data through 2024-2025 show little disruption, with effects concentrated in entry-level roles in exposed occupations; macro forecasts disagree because of assumptions, not data. It concludes the evidence gives little support for regulation premised on mass displacement or data monopolies.

## Key numbers

- 15% to more than 50%: reductions in task-completion time reported by experiments across writing, support, coding, accounting, law and translation
- less than 0.66%: Acemoglu's (2025) estimate of AI's total factor productivity gain over 10 years
- 35.9%: US workers who used generative AI by December 2025 (Hartley et al., 2026)
- roughly 16%: employment decline for ages 22-25 in highly exposed occupations (Brynjolfsson, Chandar and Chen, 2025)

## What it reports

- Macro forecasts range from Acemoglu's under 0.66% TFP gain over 10 years to Goldman Sachs' 7% rise in global GDP (about $7 trillion). Penn Wharton estimates about 10% of US GDP could be affected short term, 15% over two decades.
- Labour data show null or small aggregate effects: Yale Budget Lab finds no link between exposure and unemployment through August 2025; Humlum and Vestergaard find near-zero earnings effects in Denmark.
- Entry-level effects: about 16% decline for ages 22-25 in exposed US occupations; UK exposed firms cut junior hiring (Klein Teeselink, 2025).
- Micro evidence: Noy and Zhang, about 40% less time and 18% higher quality; customer support, 15% average and 36% for the bottom quintile; Copilot, 55.8% faster; field experiments with nearly 5,000 developers, 26.08% more weekly tasks; law students, 50% to 130% faster.
- Gains are largest for lower performers, compressing skill gaps within occupations.
- On competition: AI lowers minimum viable scale downstream; open-source and contracting weaken the case for mandated data access.

## How they got it

Narrative review of published papers, working papers and official reports from 2021 to early 2026, with an annotated bibliography. No new data or meta-analysis.

## Limits

- Selective rather than systematic: no stated search or inclusion criteria.
- ICLE's policy conclusions (against new regulation) shape the framing, for example reading entry-level effects as "adjustment".
- Many cited studies are working papers on early, short windows.

## Why it matters for companies

A compact map of the evidence for anyone building an AI business case: task-level gains are real and well measured, firm-level and economy-wide gains are still uncertain, and junior roles are where change shows first. The skill-compression finding argues for targeting AI tools and training at newer and lower-performing staff, while planning how juniors still get the practice that used to come from routine work.
