研究两党如何通过选区重划最大化赢得众议院多数席位的概率,发现均衡中强势政党更倾向于隔离对手支持者,且选举结果偏向强势政党。

Abstract

Two parties choose redistricting plans to maximize their probability of winning a majority in the House of Representatives. In the unique equilibrium, parties maximally segregate their opponents' supporters but pool their own supporters into uniform districts. Ceteris paribus, the stronger party segregates more than the weaker one, and the election outcome is biased in the stronger party's favor and against the party whose supporters are easier to identify. We incorporate policy choice into our redistricting game and find that when one party controls redistricting, the equilibrium policy is biased towards the preferences of the redistricting party's supporters.
