Multiscale Exit-Join Dynamics: Tactical Consensus and Strategic Coalition Formation

arXiv:2606.26139v1 Announce Type: cross Abstract: This paper develops a multiscale model of coalition formation in which strategic exit-and-join decisions are coupled with tactical consensus dynamics inside coalitions. Coalition value is generated endogenously from within-coalition information aggregation, while Aumann-Dreze payoffs, switching frictions, and acceptance rules govern strategic reconfiguration. The framework introduces a fast-slow architecture in which transferable coalition value emerges from DeGroot-style consensus processes, while coalition structures evolve through incentive-

Why this matters
Why now

This research is emerging as AI agent systems become more sophisticated, requiring advanced models for complex, multi-agent interactions and coalition formation.

Why it’s important

Understanding the dynamics of self-organizing intelligent systems is crucial for designing and governing future AI ecosystems, influencing everything from economic models to geopolitical strategy.

What changes

This framework offers a more nuanced way to model AI interactions, moving beyond simple game theory to incorporate dynamic consensus and strategic reconfigurations within AI agent groups.

Winners
  • · AI ethicists
  • · Multi-agent system developers
  • · Game theorists
  • · AI governance researchers
Losers
  • · Overly simplistic AI interaction models
Second-order effects
Direct

Improved theoretical understanding of how AI agents might form and dissolve alliances based on internal consensus and external incentives.

Second

Development of more robust and adaptive multi-agent AI systems capable of strategic cooperation and competition.

Third

Potential for AI systems to autonomously form and reconfigure organizational structures, impacting human-led decision-making processes.
