Bipolar Multicandidate Elections with Corruption
研究了多候选人选举中不同投票规则在遏制腐败和实现多数主义两个目标上的表现，发现只有批准投票制能同时满足这两个标准。
Abstract The goals of democratic competition are not only to implement a majority's preference on policy questions, but also to provide a deterrent against corrupt abuse of power by political leaders. We consider a simple model of multicandidate elections in which different electoral systems can be compared according to these two criteria. Among a wide class of single‐winner scoring rules, only approval voting is found to satisfy both effectiveness against corruption and majoritarianism for this model.
