International comparisons show AI effect on productivity
Federal Reserve Bank of Dallas
US productivity grew 2.4% annualized since 2024Q1 (vs 1.6% pre-pandemic); the three most AI-exposed sectors (information, finance/insurance, professional & technical services) grew 3.7% vs 1.7% for the rest, and account for 40% of US productivity gains with only 16% of hours worked. In the EU, where the same exposure index applies, there is no correlation between sector AI exposure and productivity growth. The Anthropic AI Usage Index (US 3.69, EU-27 1.85, Estonia 3.05, Poland 1.41) explains the gap: the exposure-productivity slope strengthens with national AI usage. Correlation, not causation.
