aceThe simple macroeconomics of AI
SUMMARY This paper evaluates claims about the large macroeconomic implications of new advances in Artificial intelligence (AI). It starts from a task-based model of AI’s effects, working through automation and task complementarities. So long as AI’s microeconomic effects are driven by cost savings/productivity improvements at the task level, its macroeconomic consequences will be given by a version of Hulten’s theorem: Gross Domestic Product (GDP) and aggregate productivity gains can be estimated by what fractio…
AI automation of tasks is estimated to produce modest aggregate gains of no more than 0.66% TFP growth over 10 years based on task exposure and task-level cost savings.
Those TFP gains are likely exaggerated and even more modest, predicted to be less than 0.53% over 10 years, because future AI effects will involve hard-to-learn tasks with many context-dependent factors and no objective outcome measures.
Estimates may be overstated because they extrapolate from easy-to-learn tasks to hard-to-learn tasks where learning is limited by context dependence and lack of objective outcome measures.

How to verify without trusting this page
Fetch the canonical text of any version from /api/record/TRV-2026-0378 and hash it yourself — for example shasum -a 256 on the saved canonical field. The result must equal content_hash, and each version’s text ends with prev:followed by the prior version’s hash (version 1 chains to 64 zeros). If a single character of any version had been altered since certification, the chain would not reproduce.
