Ranked Voting on Social Networks
Classic social choice literature assumes that votes are independent (but possibly conditioned on an underlying objective ground truth). This assumption is unrealistic in settings where the voters are connected via an underlying social network structure, as social interactions lead to correlated votes. We establish a general framework — based on random utility theory — for ranked voting on a soc...
متن کاملStrategic Voting and Social Networks: (Doctoral Consortium)
The effects of social networks are pervasive in everyday life, from the subtle effects on mundane, momentto-moment choices, to political revolutions driven through social media.

We propose a model where voters are embedded in a social network. Each voter observes the ballots of her neighbors in the network, from which she infers the likely outcome of the election. Each voter may then revise her vote strategically, to maximize her expected utility. Our work focuses on plurality voting, where strategic voting is a major concern. We show that in practice, strategization i...
متن کاملThe voting paradox and social networks: An empirical analysis

We provide empirical evidence for the role of social networks as a main factor of influence in the turnout of an election. More intense social networks and wider social networks are associated with a lower abstention rate.
