LLM vs. first-year PhD student on EconCS research: workflow study using stable menus of public goods

A preprint uses an open problem from EC 2025 as a testbed to evaluate AI-assisted research workflows in economics and computer science. The study examines whether human intuition in prompts, multi-turn interaction, and LLM capability compare favorably to a first-year PhD student's contributions. Key findings: human intuition in prompts improves LLM 'taste', multi-turn workflows help when encouraging ambitious steps, and the LLM performs slightly below the first-year PhD student on the same problem. The work contributes empirical evidence on the practical utility and limits of LLMs as research collaborators in formal theory domains.
