Abstract
AbstractThis study investigates the impact of media sentiment on firms' investment efficiency in the Chinese market during 2007–2017. We find that increased media sentiment can lead to overinvestment and thus distort investment efficiency, but it has no significant effect on underinvestment. Further, mediation analysis shows that financing constraints mediates the media sentiment effects on overinvestment. To mitigate potential endogenous problems, we employ instrumental variable approach and propensity score matching method. The main findings hold after a battery of robustness tests. Further tests show that corporate governance factors can ameliorate the adverse effect of news sentiment on corporate investment efficiency.
