摘要

This paper examines the diffusion of media slant. We document the influence of Fox News Channel (FNC) on the partisan slant of local newspapers in the U.S. over the years 1995-2008. We measure the political slant of local newspapers by scaling the news article texts to Republicans’ and Democrats’ speeches in Congress. Using channel positioning as an instrument for viewership, we find that higher FNC viewership causes local newspapers to adopt more right-wing slant. The effect emerges gradually, only several years after FNC’s introduction, mirroring the channel’s growing influence on voting behaviour. A main driver of the shift in newspaper slant appears to be a change in local political preferences.

中文摘要

本文考察了媒体倾向的扩散。我们记录了1995—2008年间福克斯新闻频道(FNC)对美国地方报纸党派倾向的影响。我们通过将新闻文章文本与国会中共和党人和民主党人的演讲进行尺度映射,来衡量地方报纸的政治倾向。使用频道定位作为收视率的工具变量,我们发现更高的FNC收视率会导致地方报纸采取更右翼的倾向。这一效应是逐渐显现的,直到FNC推出数年后才出现,与该公司对投票行为日益增长的影响相呼应。报纸倾向转变的一个主要驱动因素似乎是地方政治偏好的变化。
