AI and the research assistant: Evidence from economics working papers

Johan Fourie

Papers from arXiv.org

Abstract: Studies of AI in science observe isolated tasks or the authors on a byline. They do not observe the research assistants whose data cleaning, coding, literature search, and replication work language models now perform. Economics working papers record this junior labour in their acknowledgements, next to the full text. Using 24 working-paper series through October 2026, I compare papers by the same economist that do and do not disclose AI use, alongside a detector of AI-like prose. Disclosing papers credit 0.548 more named assistants than other papers by the same economist, two-thirds of the mean, and run longer, mostly in their appendices. Disclosures of operational use, such as coding and data work, carry the whole assistant difference; writing-only disclosures and AI-like prose show no consistent association with assistants or pages. The paper brings acknowledged junior labour and selective team disclosure into the study of scientific production. Within an economist's portfolio, operational AI accompanies wider, assistant-supported projects.
