Although the 1960s race riots have gone down in history as America's most violent and destructive ethnic civil disturbances, a consensus on the factors able to explain their insurgence is yet to be found. Using a novel data set on the universe of radio stations airing Black-appeal programming, the effect of the media on riots is found to be sizable and statistically significant. A marginal (1%) increase in signal reception from these stations is estimated to lead to a 2.4% and 4.1% rise in the mean levels of the frequency and intensity of riots, respectively. Several mechanisms behind this result are considered, with the quantity, quality, and length of exposure to radio programming all being decisive factors.

平等权利斗争中广播的声音：来自美国南部的证据

尽管 1960 年代的种族骚乱作为美国最暴力和最具破坏性的种族内乱而载入史册，但尚未就能够解释其叛乱的因素达成共识。使用关于广播黑人节目的广播电台宇宙的新数据集，发现媒体对骚乱的影响相当大且具有统计意义。据估计，来自这些站点的信号接收略有增加 (1%) 将导致骚乱频率和强度的平均水平分别增加 2.4% 和 4.1%。考虑了这一结果背后的几种机制，其中广播节目的数量、质量和时间长度都是决定性因素。
