摘要

媒体所有权法律规制的中心命题之一是所有权整合减少了实体观点的多样性。上诉法院和联邦通信委员会也越来越多地要求为这种趋同假设提供证据,但现有的观点多样性实证措施回避了这个问题,忽视了多样性、观点或两者兼而有之。我们的文章开发并提供了一种微调的、随时间变化的编辑观点多样性统计方法,该方法基于一个新的数据库,该数据库包含1988-2004年间25篇顶级论文的1600多篇社论。使用这种新的措施,我们评估的有效性趋同假设通过检查的演变编辑的观点在五个主要的并购过程中。我们的数据揭示了复杂的模式,挑战现有的说法,显示稳定性,趋同和分歧的观点,面对-并取决于情况-整合。这些发现从根本上挑战了现有的经验监管假设——指出了编辑政策的关键作用——并深刻地说明了所有权法规和1996年《电信法》解释的可行性。

Viewpoint Diversity and Media Consolidation: An Empirical Study
One of the central predicates of legal regulation of media ownership is that ownership consolidation reduces substantive viewpoint diversity. Appellate courts and in turn the Federal Communications Commission have increasingly demanded evidence for this convergence hypothesis, but extant empirical measures of viewpoint diversity sidestep the problem, ignoring diversity, viewpoints, or both. Our article develops and offers a finely-tuned, time-varying statistical measure of editorial viewpoint diversity, based on a new database of over 1600 editorials in 25 top papers from 1988-2004. Using this new measure, we assess the validity of the convergence hypothesis by examining the evolution of editorial viewpoints over the course of five major mergers and acquisitions. Our data reveals complex patterns that defy extant accounts, showing stability, convergence and divergence of viewpoints in the face of - and depending on the circumstances of - consolidation. These findings fundamentally challenge extant empirical regulatory assumptions - pointing to the crucial role of editorial policies - and deeply inform the viability of the ownership regulations and the interpretation of the 1996 Telecommunications Act.
