选民在竞选期间决定获取的政治信息量除其他外取决于先前对政党和/或候选人的意识形态信念。事前对候选人漠不关心的选民对信息没有什么价值,因为他们认为投票本身没有什么价值。事前意识形态很强的选民也不太重视信息,因为他们认为新闻很难改变他们的观点。因此,中等程度的党派之争具有较高的知情动机。此外,政治知识的增加对投票率的影响是不对称的:新信息增加了冷漠选民的投票概率,但降低了意识形态很强的选民的投票概率。这些结果是在信息获取和投票率的决策理论模型中得出的,该模型结合了 Riker-Ordeshook (1968) 的投票行为方法和 Becker (1965) 的个人生产函数方法。然后,这些预测将根据 1997 年英国选举研究的调查数据进行检验(Heath 等,1999)。我们的实证研究结果与理论练习的所有结果都是一致的。
The amount of political information that voters decide to acquire during an electoral campaign depends, among other things, on prior ideological beliefs about parties and/or candidates. Voters that are ex ante indifferent about the candidates attach little value to information because they perceive that voting itself will have little value. Voters that are ex ante very ideological also attach little value to information because they think that the news will hardly change their opinion. Thus, high incentives to be informed can be found at intermediate levels of partisanship. Moreover, the impact of increased political knowledge on turnout is asymmetric: new information increases the probability of voting of indifferent voters but decreases that of very ideological voters. These results are derived within a decision theoretical model of information acquisition and turnout that combines the Riker—Ordeshook (1968) approach to voting behaviour with the Becker (1965) approach to personal production functions. These predictions are then tested on survey data from the 1997 British Election Study (Heath et al., 1999). Our empirical findings are compatible with all the results of the theoretical exercise.
