Exit-and-Join Dynamics for Decentralized Coalition Formation

The paper presents a model for decentralized coalition formation driven by unilateral exit-and-join decisions, using the Aumann-Dreze value for local payoff evaluations. It establishes equilibrium characterizations and conditions for scalar Lyapunov or exact-potential representations, while also examining the impact of switching and acceptance costs on local stability. This work is significant for practitioners as it offers insights into cooperative dynamics in multi-agent systems, potentially informing the design of algorithms for coalition formation in decentralized environments.
