### Core findings
- Using five waves of the Anthropic Economic Index (January 2025 to February 2026), the authors construct two novel measures from observed AI usage across countries.
- The AI concentration index (ACI) indicates:
  - In developing economies, virtually all AI usage-based value is generated in a small professional enclave (ACI near 1.0).
  - High-income economies average 0.4 to 0.5, with concentration declining in many countries.
- The labor cost equivalent (LCE) values the time currently saved by AI at $2.7 trillion annually (3.4% of GDP), presented as an indicative measure of the labor cost of that time.

### Measures and data
- Data source: Five waves of the Anthropic Economic Index (January 2025 to February 2026).
- Novel measures constructed:
  - AI concentration index (ACI): quantifies how concentrated AI usage-based value is across occupations within countries.
  - Labor cost equivalent (LCE): values time saved by AI in dollar terms and as a share of GDP.

### Distributional patterns and predictors
- Concentration patterns:
  - Developing economies: ACI near 1.0, indicating concentration of AI usage-based value in a small professional enclave.
  - High-income economies: ACI averages 0.4 to 0.5, with evidence of declining concentration in many countries.
- Predictors of concentration:
  - Income predicts concentration.
  - Regulatory readiness predicts concentration.
  - Lacking an official English language slows broadening of AI usage, posing a barrier for developing countries.

### Key statistics and publication metadata (from source)
- LCE: $2.7 trillion annually.

- Volume: 2026.
- Issue: 147.
- Series: Working Paper No. 2026/147.
- DOI: https://doi.org/10.5089/9798229051279.001.
- ISBN: 9798229051279.

- Publication date: July 10, 2026.
- Authors: Rachel Yuting Fan, Ha Minh Nguyen.

### Implications for policy and research
- Broadening AI usage outside a small professional enclave appears limited in developing economies; policy and regulatory readiness matter for diffusion.
- Language barriers (absence of an official English language) are identified as a tangible obstacle to broader AI adoption in developing countries.
- The $2.7 trillion LCE (3.4% of GDP) provides an indicative aggregate scale of current time savings from AI, informing labor cost and national accounts considerations.
