In this work, we aim to develop LLM agents to mitigate social norm violations
in negotiations in a multi-agent setting. We simulate real-world negotiations
by letting two large Language Models (LLMs) play the roles of two negotiators
in each conversation. A third LLM acts as a remediation agent to rewrite
utterances violating norms for improving negotiation outcomes. As it is a novel
task, no manually constructed data is available. To address this limitation, we
introduce a value impact based In-Context Learning (ICL) method to identify
high-quality ICL examples for the LLM-based remediation agents, where the value
impact function measures the quality of negotiation outcomes. We show the
connection of this method to policy learning and provide rich empirical
evidence to demonstrate its effectiveness in negotiations across three
different topics: product sale, housing price, and salary negotiation. The
source code and the generated dataset will be publicly available upon
acceptance.
