Abstract
This paper examines how online interaction between firm management and investors impacts stock price crash risk. Based on the previous literature, we postulate that online interaction constrains crash risk via two channels, i.e., deterring bad news hoarding activities of managers and decreasing differences of opinion among investors. Relying on the launch of Hudongyi (the first official investor relations management platform in the world) for identification, we demonstrate that online firm-investor interaction significantly reduces future stock price crash risk and that these two channels can both explain this effect. Overall, our findings highlight the important role of online interaction in risk management.
