It is found that an oil price shock in interaction with a firm’s stock price volatility has a ‎negative effect on investment by that firm, both in the short and long-term. In the presence of ‎this interaction term, linear variables in oil price shocks are not statistically significant. There is ‎evidence that for the short-term effects of the interaction variable, the particular magnitude of an ‎oil price shock may not be as important as the fact that there is an oil price shock. For the long-‎term effects, however, the magnitude of the oil price shock does matter. Over a longer horizon, ‎oil price shocks depress investment more at firms facing greater uncertainty. An increase in firm ‎stock price volatility continues to reduce the link between sales growth and investment in the ‎presence of oil price shocks as in Bloom et al. (2007).‎
