We examine the causal effect of short sellers on innovation. Using exogenous variation in short-selling costs generated by a quasi-natural experiment, Regulation SHO, which randomly assigns a subsample of the Russell 3000 index firms into a pilot program, we show that short sellers have a positive, causal effect on firm innovation. The positive effect of short sellers on innovation is more pronounced when firms are subject to a larger agency problem and a higher degree of information asymmetry. Our paper provides new insights into an under-explored and possibly unintended real effect of short sellers – their encouragement for firm innovation.
