Herd journalism: Investment in novelty and popularity in markets for news

Abstract

Consumers of news care both about the novelty of the news they read, as well as how popular that news topic is with others. Editors choose what to report on based on consumer preferences and the coverage of their competitors. We build a continuous time model that predicts whether news providers invest in covering novel news stories or instead report on popular. We construct a dataset of cover stories to test the model and find that both novelty and popularity are associated with increased sales, but popular stories only have a lifespan of one to two weeks. We find that the impact of novelty has declined since 2006, and the lifespan of a story has shortened. While theory predicts that editors strategically alternate between reporting on novel stories and popular stories, we find evidence of positive serial correlation in the popularity of cover stories. Finally, news outlets often cover the same story. Theory predicts that competitive news outlets are more likely to pool on the stories they cover while news outlets with market power are more likely to separate.
