Responsive democracy and commercial media
研究发现，在商业媒体存在时，选民情绪波动可能损害原本受青睐政策的选举表现，因为情绪变化影响信息需求，进而改变新闻质量和选民偏好。
In an election over two policies, public mood swings whereby voters move ideologically towards a particular policy should never hurt its electoral performance. We find that this fundamental monotonicity property of preference aggregation cannot be guaranteed in the presence of a commercial media. When such a media outlet supplies news about policy-relevant uncertainty, mood swings affect demand for information. This in turn alters news quality, changing interim preferences and votes that can crowd out the ideological gain of the favored policy.
