Interaction patterns and coordination in two population groups: A dynamic perspective

摘要

We examine the influence of interaction patterns between different groups on the replicator dynamics of evolutionary coordination game. We show that: (1) Global coordination is always a possible solution in two-group coordination games; (2) There is no stable rest point within or on the axes of the phase plane F, i.e. within each population group, internal coordination is the only stable outcome at equilibrium; (3) If the interaction frequency exceeds a threshold value (p > 1/2 in our model), a moderate wealth distribution ratio will always drive the system to converge at global coordination.
