Co-evolution in negotiation games

In this paper, we focus on the mechanism of co-evolution in the negotiation situations. We formulate negotiation situations as hawk-dove games. It is an interesting question to answer how the society gropes its way towards equilibrium in an imperfect world when self-interested agents learn each other in order to improve the rules of interaction. It is known the mixed strategy will result in equilibrium in hawk-dove games, and both hawks and doves coexist. In this paper, we consider evolutionary dynamics with local matching and investigate the role of the mutual learning. We show that all agents gradually learn to behave as doves, which result in social efficiency.
