Formal Mechanisms for Market Stability in Self-Interested Agent Societies: A Marketplace Simulation Study

Jul 10, 2026

A new study on arXiv simulates a multi-agent marketplace with 18 LLM agents (DeepSeek-V3) to evaluate mechanisms for maintaining market stability under adversarial attacks. Mediation was identified as the most effective mechanism, withstanding optimized attacks that reduced honest-agent utility by 13.3% but did not collapse the market. The study defines adversarial robustness as the ability to sustain positive honest-agent utility under attack.

Why it matters: This research offers empirical evidence that formal mechanisms like mediation can help stabilize AI agent economies even under sustained adversarial pressure, informing the design of robust multi-agent systems.
