In this study, we find that relative to firms with less media coverage, stock price sensitivity to positive (negative) earnings surprises in earnings announcements of firms with greater media coverage is stronger (weaker). This asymmetry in the effect of media coverage on stock price sensitivity to positive versus negative earnings surprises suggests that greater media coverage of earnings announcements intensifies stock price reactions to positive earnings surprises but attenuates reactions to negative earnings surprises. Moreover, we find that negative earnings news is less persistent for firms with greater media coverage. Overall, our findings support the conjecture that greater media coverage increases managers’ incentive to avoid future negative news, thereby reducing the persistence of poor financial performance and weakening price reactions to negative earnings news.
Environmental, social and governance (ESG) practices are pivotal to global sustainability yet face challenges. Based on the implementation of Golden Tax Project III, we find that big data tax administration decreases corporate ESG performance. Mechanism tests indicate that Golden Tax Project III can reduce tax avoidance, cash flow and green innovation, thereby inhibiting ESG through the “taxation effect.” Conversely, the project can reduce agency costs and improve information transparency, thus promoting ESG performance through the “governance effect.” Overall, however, the project inhibits corporate ESG performance. According to further analysis, the negative effect on ESG performance mainly impacts the environmental responsibility (E) element. This paper provides insights relevant to advancing China’s “dual carbon” policy and formulating a “Chinese approach” to global sustainable development.
