We study the effects of COVID-19 coverage early in the pandemic by the two most widely-viewed cable news shows in the United States – Hannity and Tucker Carlson Tonight, both on Fox News – on downstream health outcomes. We first document large differences in content between the shows and in cautious behavior among viewers. Through both a selection-on-observables strategy and a novel instrumental variable approach, we find that areas with greater exposure to the show downplaying the threat of COVID-19 experienced a greater number of cases and deaths. We assess magnitudes through a simple epidemiological model highlighting the role of externalities and provide evidence that misinformation is a key underlying mechanism.
