Media Power
定义了媒体组织影响选民投票行为的能力，推导出媒体权力的稳健上界，并基于美国数据估计了权力指数，可用于合并分析和政策辩论。
This paper defines the power of a media organization as its ability to induce voters to make electoral decisions they would not make if reporting were unbiased. It derives a robust upper bound to media power over a range of assumptions about the beliefs and attention patterns of voters. The paper then presents estimates of the power index for the United States and shows how these can inform merger analysis and other policy debates.
