Innovation and Volatility: U.S. Evidence
Firms engaging in innovative practices have their patents to prevent competitive forces from eroding the resulted economic rents, however, there is limited evidence about the impact of innovation on risk. In this paper, we empirically examine the impact of innovation on idiosyncratic volatility. In doing so, we shed a new light on how firms involved in innovation activities will impact their volatility, in particular the idiosyncratic volatility. To do so, we empirically examine the impact of innovation, measured by patents weighted by citations and R&D expenditures on the idiosyncratic volatility of firms. Using a large sample of US firms, 8,256 firms, we find that more innovation is associated with lower idiosyncratic volatility. We also find that information uncertainty is the channel through which innovation affects idiosyncratic risk. The results are robust for different measures of idiosyncratic volatility. These results have empirical implications for investors, managers, and firms engaging in innovation related activities.
