Demand for Slant: How Abstention Shapes Voters' Choice of News Media
研究发现，选民可以选择弃权，这打破了意识形态隔离，导致倾向性强的选民反而比中间选民更偏好中立或温和偏斜的新闻，从而产生新闻消费的跨意识形态交叉。
Political commentators warn that the fragmentation of the modern media landscape induces voters to withdraw into 'information cocoons' and segregate along ideological lines. We show that the option to abstain breaks ideological segregation and generates 'cross-over' in news consumption: voters with considerable leanings towards a candidate demand information that is less biased towards that candidate than voters who are more centrist. This non-monotonicity in the demand for slant makes voters' ideologies non-recoverable from their choice of news media and generates disproportionate demand for media outlets that are centrist or only moderately biased. It also implies that polarisation of the electorate may lead to an ideological moderation in news consumption. © 2014 Royal Economic Society.
