Overcoming Ideological Bias in Elections
研究了选民在意识形态和候选人能力之间权衡的模型，发现强制投票可能导致次优结果，而自愿投票通过内生调整投票率总能实现社会最优。
We study a model in which voters choose between two candidates on the basis of both ideology and competence. While the ideology of the candidates is commonly known, voters are imperfectly informed about competence. Voter preferences, however, are such that ideology alone determines voting. When voting is compulsory, the candidate of the majority ideology prevails, and this may not be optimal from a social perspective. However, when voting is voluntary and costly, we show that turnout adjusts endogenously so that the outcome of a large election is always first-best.
