Strategic Voting in a Social Context: Considerate Equilibria

We investigate voting under the perspective of a strategic game. We take into account that the agents are members of a social network in which every group of individuals has consideration for their relatives. Agents are not fully selfish as they are reluctent to act in a way that harm their partners. The associated notion of equilibrium was introduced by Hoefer et al. [7] and called considerate equilibrium. We propose to study its existence and the ability of the agents to converge to such an equilibrium in strategic voting games using well-known voting rules : Plurality, Antiplurality, Plurality with runoff, STV, Maximin and Copeland.
