Extremism, campaigning and ambiguity

This paper studies a model of how political parties use resources for campaigning to inform voters. Each party has a predetermined ideology that is drawn from some distribution. To a¤ect the voters the parties use campaigning to inform the voters about the policy of the party. We study a symmetric model with two parties and ...nd that, the farther away parties are from each other (on average), the less resources is spent on campaigning (on average) in equilibrium. Thus, the main result is that if parties are extreme, less information is supplied, than if parties are moderate.
