摘要

媒体有发表耸人听闻的新闻的动机。我们研究了在并购谣言的背景下,这种激励如何影响媒体报道的准确性。使用一个新的数据集,我们发现准确性是由记者的经验、专业教育和行业专业知识来预测的。相反,不太准确的故事使用模棱两可的语言,并以具有广泛读者吸引力的知名公司为特色。投资者没有充分考虑到这些特征的预测能力,导致最初的目标价反应过度,随后出现逆转,与有限的注意力一致。总的来说,我们为媒体准确性的决定因素及其对资产价格的影响提供了新的证据。

Rumor Has It: Sensationalism in Financial Media
The media has an incentive to publish sensational news. We study how this incentive affects the accuracy of media coverage in the context of merger rumors. Using a novel dataset, we find that accuracy is predicted by a journalist's experience, specialized education, and industry expertise. Conversely, less accurate stories use ambiguous language and feature well-known firms with broad readership appeal. Investors do not fully account for the predictive power of these characteristics, leading to an initial target price overreaction and a subsequent reversal, consistent with limited attention. Overall, we provide novel evidence on the determinants of media accuracy and its effect on asset prices.
