Economic evidence / native study periods
What happens when people use AI?
Different tasks, different results. These studies are outside the country ranking.
Consulting tasks and the limits of assistance
Over 25% faster on tasks within GPT-4’s capability758 BCG consultants completing realistic knowledge-work tasks. The reported speed gain applies to the tasks within the tested model’s capabilities.
Working paper reported 21 September 2023 · journal publication March 2026
Performance depended on the task; assistance could worsen results beyond the model’s capabilities. This is historical, task-specific evidence, not a national productivity estimate or a claim about today’s models.
Read the study ↗ · 2026 publication ↗Experienced developers, familiar repositories
AI-allowed tasks took 19% longer16 experienced open-source developers; 246 issues in repositories they knew.
Early 2025 experiment · published July 2025
This setting does not represent all developers or current tools. METR’s February 2026 follow-up identifies selection effects and redesigns the study; do not extrapolate this effect to countries.
Read the study ↗ · 2026 publication ↗Customer support in one organization
15% more issues resolved per hour5,172 customer-support agents in the authors’ updated paper.
Study published 2025 · earlier company rollout
Effects vary by experience and skill. A company-specific productivity result is not measured national output or realized net savings.
Read the study ↗Countries and economies follow source reporting conventions; boundaries and listings imply no position on sovereignty. Missing polygons remain accessible through country search and the table. AI estimates, surveys and studies are separate evidence. No universal impact score is calculated.
