Information and endogenous first mover advantages in the ultimatum game: An evolutionary approach

We endogenize the first mover advantage in an evolutionary analysis of an ultimatum game where Responders are characterized by acceptance thresholds and Proposers by decision rules for how to condition offers on any available information about thresholds. The higher is the probability of receiving correct information about thresholds, and the lower its price, the larger is the share of the surplus that Responders obtain. While reliable and cheap information about Responders’ thresholds is desirable to an individual Proposer, in the long run it hurts Proposers as a group.
