Abstract:     
We examine the 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 Russell-3000 firms into a pilot program and removes the tick restriction on their stocks, we show that short sellers have a positive, causal effect on the quality, efficiency, and originality of corporate innovation. The exposure to patenting-related litigation initiated by short sellers is a plausible mechanism through which short sellers affect firms’ innovative activities. Our paper provides new insights into an unintended real effect of short sellers – their improvement of technological innovation.
