Exploiting the staggered removal of short-sale bans in China, we document unintended real effects of allowing short selling in an emerging market featured by concentrated ownership and weak investor protection. Pilot firms have worse short-term and long-term market performances after the removal of short-sale bans. Additionally, pilot firms undertake less risk and have worse performance following the launch of the program. The effect is stronger when controlling shareholders' private benefit is large and when corporate governance is weak. Faced with increased short selling threats, pilot firms cut capital investments and R&D expenditures, reduce equity financing, and lower debt ratios. Contrary to prior studies showing that short selling encourages value-enhancing risky investments in developed markets, our findings suggest that in emerging markets such as China, short selling can result in value losses by inducing firms to forgo profitable risky projects.

Using the extreme returns of firms in unrelated industries of institutional shareholders' portfolios as exogenous variations in institutional investor distraction (Kempf et al. 2017), we find a positive and significant relation between institutional shareholder distraction and stock price crash risk. The effect is associated with weakened monitoring, and it becomes stronger when alternative corporate governance is weaker and when managers' incentives to hoard bad information are stronger. Managers reduce firms' accounting conservatism when institutional investors become distracted, which is evidence of an increased motivation to hoard bad news. Overall, our findings shed additional light on the important monitoring role of institutional investors in corporate governance.
