ABSTRACT: We show that
coordination always occurs in scale-free networks by social local interactions
regardless of the values of parameters, while it occurs in regular networks if
and only if the number of links times a payoff parameter exceeds the threshold.
Scale-free networks are ubiquitous in the reality. We study a two-strategy pure
coordination game on networks that indicate who plays with whom. A player
chooses a strategy by Logit choice and the strategies are dynamically updated.
Stable steady states are investigated.
